My 1084 monitor is dead for years. It turns on and I can hear the noise from its board and even the audio but no picture :(
My Amiga 2000 has only mono composite. All I have is the RGB to Scart+Audio cable + Scart to Composite+S-video adapter.
Can I make RGB to Composite/Component converter? =(

I had similar issue, it was the infamous "flyback transformer".

What's that? Is it possible to repair it?
I remember my dad was using it as TV when I was child, that's why it died soon x)
I know someone here that sell A520 for $40, don't know if it's worth or not.
-
Maybe sometimes, you just have to realize that old hardware breaks down.
I used a flatscreen tv/monitor with scart input, the picture was perfect, takes up less space and uses less power.

Why don't connect it to your LCD-TV with your RGB to SCART cable?

well its a common cause of failure. There is this excellent site:
http://www.jammarcade.net/commodore-1084s-p1-repair-part-ii/
but dont try it, high voltage, leave it to professional, blabla.
Is there a high pitched noise?
The hardest part is finding replacement. Original is quite pricey. I found cheap Chinese copy, locally, think it was less than 10eur.

My TV has no Scart port, only HDMI/Component/Composite.
I thought it works only with 1084, so can I connect it to any TV with scart port?

Yes, there is high pitched noise and the power LED doesn't turn on but it's powered on.
It's the Philips model of 1084 (non-S)

Generally saying YES, but old scartcables don't usually have all the needed wires.

Most of LDC-TVs also works as a flicker fixer, so you will get flicker free hires interlaced mode as bonus.

Or you can get yourself a nice Indivision and use just about any modern monitor or TV in existence. :lol:

What part of "poor boy" did you miss Mike?
That is an expensive option.
-
You could try using a GBS-8220... they go for around $20.00. I used it briefly before I bought an indivision.

My time is worth more than money. If I can buy a thing for $90 and have it installed and working in 15 minutes, vs. posting questions on forums, buying two or three $20 cables, moving the TV, plugging them in, unplugging, pushing buttons and trying different settings, going back and reading more forums, etc., etc.
TL;DR. If I can buy a thing that "just works" verses di**ing around for two or three hours trying to kludge together a poorer quality solution, I consider myself having saved money.

The flyback transformer is a high frequency transformer that produces the HV for the CRT anode as well as several other voltages. If a replacement part is available then changing it is fairly straightforward but you do have to be careful poking around in monitors. I've repaired CRT monitors for decades and could fix it if you happen to be local to me (Seattle area) but shipping both ways would be cost prohibitive. Whatever the case don't throw it out, CRTs are not manufactured anymore and the last tube rebuilder shut down a couple years ago. What's out there now is what we have and when they're gone they're gone.
-
It's all very well saying hoard old CRTs even if you don't know anyone nearby to fix it but seriously, who has the space? I managed 28 years out of my Acorn ADF-32 28-ADF32 using with both an Atari ST in the 80s and early 90s and then my AGA Amiga since 1995 and I consider that good service. Even when the power button broke I continued to use it (it was stuck 'ON') by plugged it into an Eyetech external Amiga PSU. When it broke this year I just thought it's seen its day to be honest and over a quarter of a century's use is awesome! Sometimes you just have to let go and I'm very happy with my Benq BL702A ;-)

I have also found that in the amiga world..."poor" equals I don't want to spend MY money.

LOL. Ain't that the truth. I've reached the age in my life where I have more money than time, and will gladly spend it on things that I enjoy. Amiga is not a cheap hobby. Go build houses out of popsicle sticks or something, if you want a cheap hobby. :laughing:

"Funny" story SACC sells tested used donated amiga (a 1080) stuff at AmiWest.
I was at the SACC table where a user asked how much? I said $20 us.
He said too much... (LOL) kind of

There are more options besides hoarding it or throwing it away. It's easy to find someone who will take it, with people paying $100+ for beat up vintage CRT monitors on ebay it's not hard to give away even a dead one if it's something vintage. Most of the older ones are easy to fix, they're very simple. A lot more fun to work on than the modern stuff and to my eyes they look much nicer than LCD.

Okay, come to a SACC meeting, I will give you a monitor!

I've given away about five of them over the years. You can't sell 'em, since there's almost a 100% chance of them getting damaged in shipment. So unless you can find someone who wants them locally they're about as useful as a doorstop, lol. ;)

I bet if you post it on craigslist it will be gone in no time. I've shipped CRT monitors successfully but it requires careful packing and is not likely to be worth it for one of these. There are some where it would be though, for a while I was looking for an IBM EGA monitor for my XT but I eventually gave up. A few of them went up on ebay but they all sold for >$300 + shipping.
15kHz RGB monitors are popular with the arcade guys too as bench test monitors.

Just bought an Amiga 500 with A520 which works fine, colored output.
But when I connect its A520 to my Amiga 2000 rev6, it gives me grayscale output :( :(
-
LOL!!!
Actually, it should be around 40$ CAD.
I've had a real hard time to find a way to "clip" the color levels properly. I'm in what we call the NTSC problem or "Never Twice the Same Color"... :roflmao:
I changed the design alot and now I'm using a ready made color conversion matrix on a chip. This chip was designed for new gaming console in order to convert RGB signals to Components / S-Video / Composite video signals. :razz:
Prototype will be arriving soon from the shop so stand by for more news about it's performances.
In the mean time, check out if your LCD TV is compatible to 240P. Fast way to test it is to connect the Amiga monochrome signal into the Y input of the components port. If you have an image, bingo, you're good! If you have a "no signal" message , then your TV can't interpret 240P. You can try put your Amiga into interlaced mode (480i). The image should appear then. You need another LCD screen. Most Sony Bravia and Samsung TV are compatible.
Cheers!

Yes come to a SACC meeting or come to Amiwest and take home a nice working 1084 monitor. Or invest some money in your beloved Amiga and get an Indivision and never worry about being in this situation again.
Or, enjoy that classic monochrome gaming and pretend your Amiga is a Macintosh.

:roflmao:
The RGB-Component converter solution is to bring the Amiga video port into the 2000's era. (HDMI would be 2010's). Problem with Indivision is that it does not work on non AGA Amiga, which is my case. I'm offering an alternative at a reasonnable price. :hammer:

My A2000 has an Indivision in it. Works fine. Just make sure you order the ECS version.

Thanks, I'll try to find someone to repair it for me.
Just got an used 1084S-P and it was working fine for 5 minutes until the picture started to shrink and I smelled something bad :confused:
I had to turn it off quickly and didn't turn it on anymore :(

Other options, i have one of these.. plugs into the video slot and provides component video:
https://gglabs.us/node/2014
He was selling them a while back on ebay,but i dont see them now. Other option is if you have the know how he provides the pcb files and parts list to build one.
this version works off the external rgb port, a better 520 per say and offers component video:
https://gglabs.us/node/983
he claims to be working on a new better version also.

Thanks, I have ordered GBS-8220 but need to repair 1084s too.

Have you tried making a VGA adaptor and hunting down one of the VGA monitors out there that do RGB (https://gamesx.com/wiki/doku.php?id=av:combo)? Many can be found at secondhand stores for virtually nothing, and new models that are RGB-capable are being discovered all the time.

Interesting, I didn't know that but it's also hard to find those.
I need to buy HR 7506 :(
Where can I buy?

You can get a used LCD TV on EBay or Craigslist for $20-$30
CRT is done.
