All the sudden my picture is bowed in the top left and bottom right

Yes, this is rare but I have seen it before--not fixable if it is what I think it is----It is what is called a Dome effect---the shadow mask in the picture tube is actually contracting and or expanding depending on temperature---

Directly behind the phosphor coating (the stripes that you see on the screen) is a metal screen--the holes or perforations in it line up with the stripes on the phosphor screen.

Some masks either have a material or a defect causing the dome effect----Not likely to be anything else---a Pin amp problem will not usually act the way you describe but a shadow mask inside the picture tube will act exactly that way.

If you know what you're doing - why not. Most probably something has got loose inside the lens and needs to be fixed.

I just had the convergence replaced and have a great picture

Yes, you have a bad convergence Ic--set uses two of them---have someone change both and adjust the set in the Tech menu--if you need more information or help email me [email protected]

the colorwheel is collapsing and needs replacing. it's under a metal brace between the colorwheel and the lens. it's a 4-sided mirror tube that is glued together, and the glue wears out after a while.

I just replaced the 2 convergance chips, but it did not seem to fix the problem. I then tested all the resistors that feed the convergence chips anf there was a 2.2 ohm fusable blown. IT was R7050 on mine. That seemed to fix it so that I could adjust all the colors through the convergence 2 screen. There seems to be a slight bow near the bottom when you look at the c2 screen, but not noticable when you are watching a picture. Since I got this broken, I am not sure how perfect it should be.

If anyone can send me the service manual, I would appretiate it. Thanks.

Replace Both of your STK ICs convergence ICs STK392-110 use 150s Better ICs Call Mats 1-800-628-1118 Also RK42 RK46 RK48 RK50 RK54 RK58 RK60 will have to get back to you on resistor values

This is a convergence board problem. Have a tech replace convergence IC's. The part no. starts with STK. If you are good in soldering and know how to test resistors, you can do it.

Convergence ICs are faulty what is your model number? I can post which ICs you need and where you can get replacements that come with free instalation instructions so you can do the repair yourself
