Title: In desparate need of a flyback for 1084S-D1! Please HELP!
Post by: TakeShad on September 18, 2010, 09:12:19 AM
Hi,

My 1084S-D1 died out after 20 years and I just need to get it back into action. I can't stand using my Amigas with any other monitor or TV that I can get a hold of.

Sadly, I can't get a hold of another 1084S as they are very rare in my country (Poland) now. My only hope is to fix mine but I need a new flyback for it. The replacment flyback for the orignal 1084S-D1's flyback (Daewoo DCF1580) is HR46045 which is hard to find at a reasonable price since it's old and many people take the price into the realm of absurdity.

Maybe someone will be able to help me out by offering a flyback for 1084S-D1 in a good price? I would pay via paypal.

Is there any reason you couldn't use one of these instead?
http://amigakit.leamancomputing.com/catalog/product_info.php?products_id=918

It would possibly be less than finding and shipping a flyback. And are you sure that's the problem. I know they do go bad, but I've seen other bad components make it appear to be a bad flyback. Of course if it's burned the case or motherboard, it's a good bet to be the flyback.

Edit: Yeah, my lucky 1300th post.

I hate the image that modern VGA and LCD monitors are displaying when I use Amigas with them. I just love the softness and the colors of 1084S and I really can't use my ammys without it. Besides, scandoublers are even more expensive than I thought they would be.

The problem is also that... I'm poor. I can't afford a £70-100 (plus shippping).

There's also the fact that I've been using my 1084S-D1 with a variety of retro stuff, like NES and C64. I have a whole retro corner that was plugged to 1084S and now that corner is dead with its center part gone... :CRY:

I don't have a flyback.  It seems to me that if you are up to changing one out, you may be able to arrange some other solutions.

There were a number of monitors that would sync down to Amiga frequencies (15kHz ?).  I have seen them listed on the net.

The other computers you have connected to the 1084 are not using the analog RGB input.  They use color composite input.  There are many TVs with color composite input (stereo sound, too) available in Thrift shops since the HD standard has obsoleted them.

I understand Amiga video looks decent through S-video.  If you can find a TV with that input you can be back in business, perhaps with more options for display.

Yes, I'm from Poland and that's the problem. I'm poor and we don't have many 1084S here. Even if I can find the flyback on ebay, the price of the shipping will be so high that it really doesn't pay off, so to speak.

I really need some help. Please guys, help me out if you can. All that I have to spend is 45$ so it must include shipping.

Did you check the solder joints on the flyback? I've seen a lot of 1084's fail because the joints to the circuit board open up. With the high frequencies in the flyback, it tends to vibrate & break the solder joints, which can just open up, or even arc & spark then burn up. It's worth a shot to touch up those solder joints & see what happens.

No, the flyback is dead. I have given the monitor to a service shop and I have been told that it's deadly dead. Nothing can be done with it. As for the link you've posted - it's a great shop and the price is excellent but do they accept paypal and do they ship overseas? :<

Surprisingly, hrshop.es doesn't have HR46045 any more but even if it was there - the price would be an overkill. The prices in that shop are ridiculously high.

Working 1084s are in short supply everywhere.  Ppl value them almost as much as Amigas, repair them when they fail.  Our community is facing a monitor crisis.  That's why several of us have tried to point out inexpensive work-arounds and HD adapters.

@Plaz: Sadly, HRShop doesn't have HR46045 any more, like I said before. As for that Equivalent Flybacks list - I know all of the equivalents but I have only found MSH1FCT31. I wanted to buy it but A) it's expensive (but now I will be able to buy it) B) I have been told that replacing a flyback is a tricky business and there are many problems with high voltage if you're using anything other that the original model. Will MSH1FCT31 really work?

Post by: Plaz on September 22, 2010, 12:48:16 PM
Typically I've found cross referenced parts work well. There is always that 1% chance a substitute part does not perform. I was able to track this flyback information from serveral sources, so personally I would not have a problem installing the substitue.

Over 27 years I've repaired a couple thousand monitors, replace hundreds of flybacks and often used substituted parts when necessary. Another thing that's VERY important in high voltage section repair is to find and replace any other componets that failed along with the flyback. Often a flyback will wipe out other parts when it fails. How often I've seen techs replace a couple of bad parts, turn on the monitor and fry the same parts all over again. :P All bad parts must be identified and replaced before turning it on again.

It's also possible for other components to die that give the appearance that the flyback has failed when it hasn't. In the case of your 1084S though, flyback is a common failure. I'm not bashing your tech guys, and they might be great. But I'll just warn that I've also repaired monitors first looked at by other techs. I think the repair was too difficult for them so they claimed flyback failure and gave large repair esimates I guess in the hope that the customer would go away.

If possible have your techs replace EVERY electrolytic capacitor. After 20+ years, they are all bad or going bad and can cause a bad picture or a newly repaired monitor to fail again. They are not very expensive. The whole monitor can probably be done for $10-20US

One last item... I have seen monitors that have "leaky" picture tubes. (at least 2 of them were 1084's) The bad picture tube causes the flyback and high voltage circuit to be over worked, run hot and fail again soon. This is rare, but worth knowing if you get your monitor repaired and it dies again after a short time.

BTW, you can get a look at my most recent monitor repair here.... :)

The man that I have given the monitor to is a 30+-year-in-the-business friend of my dad. I don't know how good he is but I think he's quite good.

He said that the flyback died along with a resistor that made the flyback going. He took care of the resistor in a few minutes and also repaired the power switch but he failed at finding a replacement for the flyback and then he said that if I can find one myself, he will repair the monitor easily.

I hope he's right and there's nothing more than the dead flyback.

As for the picture tube of my 1084S-D - it's in great shape, that I am certain of.

BTW - great gallery!

If he has been around that long perhaps he knows someone that still rewinds flybacks - yes, in the 'old days' when a living room color tv in the U.S. cost (http://www.tvhistory.tv/tv-prices.htm) one third of a new car (http://auto.howstuffworks.com/1960-1969-volkswagen-beetle1.htm)  there were places that rewound them.

The flyback is part of the tuned circuit of the horizontal deflection amplifier, so you *probably* need to replace it. If you could get away with just supplying the HV from an external source, they are not hard to build:

Post by: TakeShad on September 22, 2010, 04:17:18 PM
He told me that it's no use in rewinding flybacks because a regenerated flyback will die very quickly - it will live for a few months at best. Also, there's a big risk that something will be wrong and the whole monitor can just kick the bucket.

As for building my own flyback - I would just kill myself with the HV...

Post by: Plaz on September 22, 2010, 08:12:21 PM
Sounds like you have the right person to repair your monitor then. Just need the correct part.

As for winding your own... not unless you're an expert. I havn't done a winding myself since 1977 and that was just for testing. I didn't use it in a repair. HV is normally 12,000 - 36,000 volts. You don't want to mess with that.

I have given up on the flyback at this point. It's too expensive and there is a risk that a replacment part will not work with my 1084S-D, as I have been told by some tech guys.

The hope is not dead yet, though. Thanks to the help of a very generous and kind man, I may be able to buy a new monitor. Ebay is out of the picture since shipping to Poland is truly pricey (sometimes it's over 60 EUR). Thankfully, we have a Polish web auction site that lists two 1084S-D right now. The problem is that those auctions generated a hell of attention and many people are bidding.

http://allegro.pl/monitor-commodore-1084s-black-cdtv-cd-tv-i1242864321.html

I don't even dream about the black one since it's considered a rarity among Polish Amiga fans and the price will be very high. But thanks to the help of the person I've mentioned above, I might just have enough money for the regular white one... It all depends how the listing will turn out.

I am surprised by two things; One, that I could read, or at least understand, much of the Polish technical text on the site; Two, that the monitor markings, shipping boxes, even the manual was in English - I thought CBM was more internationalized than that. Especially since the founder was from Poland!

You might also look for older Daewoo, Philips or Magnavox monitors that have the proper inputs. In the PC world they were called CGA monitors.  These are the same monitors that Commodore put their name on and you might find them cheaper. Also look for old multisync monitors. For years I used an NEC multisync that had all the correct connectors and worked great with my Amigas. Make sure any multisync you look at has a freq range of 15Khz-31KHZ at least. Many don't go down to the 15K that you may require.

I've found a guy who has Philips CM11342/00G for sale but... The monitor seems to have strange inputs.

I don't see Chroma and RGB seems to be modified in a way that won't allow a standard 9-pin RGB cable to be connected...

EDIT: OK, the RGB input is normal. Just the cable is weird, with only one screw. Still, the lack of chroma bothers me since I have a LCA cable for my C64.

What do you guys think about this? Should I buy this monitor?

I don't believe that this monitor supports LCA. It doesn't only lack Chroma input. It also doesn't have CVBS<=>LCA switch.


Unfortunately for you, your right, that model doesn't have Chroma & Lumma inputs, these were on other versions that commodore made for different countries. :(

The RGB Connecter pinout's for it can be found here

That's a FAIL. I love LCA picture from C64... :<

What about the picture on this Philips? Is it as good as on the 1084S? I've read that Philips used worse tubes and the picture wasn't so good. :<

Yes, but I've read that it's different with Philips-branded monitors.

Had one of these and I didn't like it. The  raster was too visible so the pixels weren't beautiful, they look much  better on the original Commodore one.

Can only say that the ones I use give an excellent picture, never had any problems with them other than the flyback going on one, but when that went a number of years ago you could still purchase the flyback quite easily... :)

This monitor is CM8833-II, if that helps.

Any quick reviews?

EDIT: BTW - 1084S is .39 mm dot pitch and this Philips is .42. Maybe it's true that this Philips has worse picture?

I really need some good info soon. If I don't buy this monitor fast, the owner will list it on that auction site that I've told you guys about as a part of an A500 set  and then I won't be able to buy it.

Thats one of the ones I've got, it gives a good clean picture, although with age the focus can go a bit. but this is easily rectified by adjusting the focus & or voltage on the flybacks potentiometers. :)

Don't know if your going to be able to view it before you buy first, as buying an old monitor online you're taking the sellers word for it and his opinion that the picture is good and the sellers opinion on what's good can be very subjective. :)

According to www.amiga (http://www.%3Cb%3Eamiga%3C/b%3E)-hardware.com/, 1084S is .39 and CM8833-II i .42.

EDIT: I've bought it. The guy didn't want to wait any longer so I had to decide. I decide to go with it, mainly because it uses flyback HR7533 and that model is cheap and avaiably even in my country so in case of emergency I will be able to repair it. I hope I will not be disappointed and this monitor truly is just like 1084S.

Yeah, that is confusing.  They are actually talking about a different monitor, the 2080.  
Not sure why it's in their 1084 section?:confused:

So you didn't lose any quality and possibly gained some!  :)

Yeah, that always seemed odd to me... I think they wanted to say that 2080 is much like 1084 but has a different phosphor. They should have made it clearer, though.

I hope so but then again, I've lost LCA so now my C64 will have to be plugged through the crappy composite... :<

Also, the monitor is still a mystery. I'll wait with the champagne until I know it really works and is without faults. Oh, wait... I can't afford champagne.

That's a nice one but it's expensive for my wallet. I can't even afford 79,00 EUR for the monitor and the shipping is additional 29,00 EUR.

Like I said, I've already bought the CM-8833-II that I was talking about earlier. It was the only Amiga monitor I could afford on that Polish auction site. I hope it will be as good as 1084S (it should be). It will arrive in the next few days so I'll be sure to make an update.

EDIT: It's so ironic... Just a few days after I've bought the CM-8833-II from that polish auction site TWO new 1084S auctions popped out and the price on both of them is low... I seem to have bad luck with this monitors... I just hope the Philips that I've purchased won't die on me in the first hour of using it... :<

The monitor arrived but I can't say that I'm totally pleased. I don't want to brag but sadly, the other guy was right and something is wrong with the raster in this Philips monitor.
 
 The sharpness is incredible and the colours are very rich, much better than on my old 1084S-D1. But the problem is that the pixels are very visible and I don't like it at all. My boyfriend says it's cool but my eyes don't like that. I loved 1084S softness... :<
 
 Also, the monitor has bad pixels... One in a very noticeable place. I didn't expect this from a CRT but I did see dead pixels on some CRTs before so I'm not totally shocked.
 
 I'm adding a low-quality video of some of my CM8833-II testing.
 
 I also want to thank everybody who tried to help, especially you-know-who-you-are. I may not be fully pleased with the new monitor but I've been given a lot of help on this forum and I really appreciate it. THANKS!!!

If you want a softer picture (although I don't understand why... :confused:) then all you have to do is, take the back off and on the flyback transformer you will find two adjustment potentiometers, one for Volatge & one for Focus.

A tiny adjustment of the Focus pot, will give you the softness you desire... :)

It won't help. As someone stated before, CM8833-II has a very strange tube that features bad raster that makes every pixel visible as hell. The image looks like crap because you can see the net of pixels. :<

I am sitting here looking at my CM8833-II right now with the back off, to put it quite simply, if you want a softer picture open it up and adjust the focus and you can have a picture you should be happy with. :)

It's nothing to do with a so called 'bad raster', although I still don't understand why anyone would go to all the bother you have done, then want to change a sharp picture to a blurred one... :confused:

@Franko: It is about the raster. Maybe your CM8833-II has a different tube. Mine has an awful raster and it makes all the 2D games look bad. The pixels are just too visiable and I can't believe Philips put a tube like this into a computer monitor.

I can't show it because I don't have a high-res camera
Title: Re: In desparate need of flyback for 1084S-D1! Please HELP!
Post by: Franko on September 30, 2010, 06:26:09 PM
My CM8833-II also has a Phillips tube, along with my other 1084s,  CBM 1942 & Microvitec monitors they all have one thing in common, that is if you're sitting close enough to the monitor then the pixels array can be clearly seen on all of them.

I'm still not quite sure why you find this a problem though, or what you were hoping to achieve with this monitor, as with any cathode ray tube, the pixel grid array will always be visible if you're sitting close enough and your eyesight is good... :)
Title: Re: In desparate need of flyback for 1084S-D1! Please HELP!
Post by: TakeShad on September 30, 2010, 06:42:41 PM
No, you're totally missing the point. It's not about the fact that you can see the pixels if you're close enough. That's obvious with CRTs displays. The problem with CM8833-II is that the pixels are very visiable, the raster is strangely made and it causes every pixel to be too noticeable even from a distance. I see this for the first time. I've used many CRTs in my life and I never noticed anything like this.

What I wanted to achieve? 1084S-level image. Philips CM8833-II has a much worse raster.

My Dreamcast performs great via RGB with CM8833-II but that's mainly 3D graphics and the raster isn't a problem in 3D. It's a problem in 2D. For example, Kickstart 1.3's start-up screen on my A500 looks like crap on this monitor because you can see a net of pixels even from big distance. The image doesn't look solid - it looks as if it was made from grains of sand.
