Thats a strong possibility as the STK730-010 is the power amplifier for the convergence circuits. Its an inexspenive part to replace and easy to install. You can get a replacement IC at the following link and they provide free on line tech support for free as well as send instructions on how to replace the IC. Here is thier link if youd like it. I am one of thier on line tech supports as well as one of thier board rebuilders.

Rca P52690 Distorted image


First of all, if you have any warranty or service plan, exercise them. Secondly, you can bring it to a local service center. There are also a lot of technicians willing to work on-site at your home. You mentioned an IC that needs replacing. I cross-reference that and it seems it is a very inexpensive part ($7.90) that you may be able to replace yourself if you have used a soldering iron. It is simply a switching regulator. It says it controls power switching on CRT displays. If your TV is a CRT don't bother with it, the repairs can cost you more than half of what a VERY decent LCD would. Go into a local Radio Shack and ask about the 37'' AKAI, it even has a built in DTV tuner, the picture is beautiful. It supports 1080i/p but it is scaled(1366x768).

The color is distorted on the lower left hand side of the TV, or maybe distorted is not the correct wording. It looks like there is a yellow haze in that corner...

PHILIPS 60PW936317 - COLORS GOT DISTORTED AS I WAS WATCHING TV


Your convergence chips and convergence resistors are going bad. When they fail the screen colors will look distorted/3d looking.  Another symptom is one or more colors can't be converged using the convergence menu. You can purchase the parts over the internet. Just make sure you get Sanyo brand convergence chips and the correct flame proof resistors. You can also check the site www.TvRepairKits.com. They are working on a complete kit for this model.

Probably the convergence circuit, the STK output devices, associated resistors, power supplies, etc. Generally about $250 to repair. Have a service tech come out and check it out, also have them eveluate the condition of the crts before going too far. Good luck
