The picture separates into the blue and red images. is this worth repairing? can I repair it myself?

Yes you can repair it yourself if you know how to unsolder and solder IC's
The two large Ic's in your convergence Circuit has failed. You will need to replace both of them to return to normal viewing, Also the unit may need a convergence alignment after repair to insure picture quality.
Your tv's menu should have a user convergence alignment option in the setup option, but for factory quality have a technician do a factory mode alignment. Replaced both IC's with part#'s STK-392-120

Hope this helps you:
Please leave comment for futher assistance.
Thanks Lavell

Same convergence problem as the other guy, but...

I would not recommend replacing them yourself if you have no soldering experience,There are many smd's very close to where you need to solder that can easily be lost or damaged if you don't know what you're doing.

Bad convergence on my jvc model av56wp74

If you can solder and you are comfortable working inside a set where there are potentially dangerous high voltages, yes you can fix this. The problem is likely to be either bad connections on the convergence ICs or defective ICs. If you still have the results of the previous repair, please post those here and I'll provide you with additional details and instructions.

Capacitors on DM Module

I just fixed the capacitors on my WS-65713. I can email you instructions with pictures if you wish. You will need to de-solder and solder on new capacitors but if you check out video instructions on utube you should be okay with some practice.

Tv won't power on

Big Irish,

I saw how close to the bottom of the cabinet the main board and
all the soldering connections were and chickened out on repairing it myself. I found a local fixit shop who fixed it for $160

Thanks for the information though. I appreciate your suggestions.

Picture is going bad

    The problem you are describing is called convergence mis-alignment.The repair is mechanical and requires soldering.
If you are prepared, I can take step-by-step.......

1) Remove rear cover and front speaker grill cover for access
2) Locate large,finned heatsinks that have STK IC's on them.
3) Replace Ic's
4) reassemble
5) check alignment

For more detail,please look it over and tell me STK # by
tomorrow if you have time...........T.

ProScan 52" Projection Turns on the right off after clicking a few times

I've had the same problem with a 60" proscan. The tech repaired it ($400 for the repair) and left a note inside the chasis explaining what he did (in case he had to fix it again). He replaced a resistor and re-soldered a number of ICs. It happened to me again, and I may attempt the repair myself this time around.
