In desparate need of a flyback for 1084S-D1! Please HELP!

[Franko]

So... what's a flyback?

This...

[Franko]

The RGB socket is fine, If I recall correctly on that model the CVBS input can be used as Lumma and the phono socket above the audio input can be used Chroma for ... (need to check my through my manuals first...)

[Franko]

Still trying to find the manuals... be back in a bit...

[Franko]

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

I have four 1084s of different styles, can honestly say the picture on them all are fine no matter who manufactured the tube...

[Franko]

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

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.

[Franko]

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...

(WARNING:- Remember, Lethal High Voltage Involved Here...) :nervous:

[Franko]

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]

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...
