This tv have a problems call convergence,it dead.The tv convergence board must have the 2 STK convergence ICS and some or all it resistors are dead.These parts must change to solved covergence problems.The shop will cost u $300-350 for parts and labors.
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.
You have a convergence problem. Here are some of the most common symptoms.
Screen looks 3D One or more colors can't be adjusted when when using the convergence menu. Screen is bowed in but stationary.
Solution: You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit inlcludes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself. Its an easy fix.
You need to replace both convergence ICs they are STK392-120 this is an easy repair that you can do yourself and save yourself around 400.00 for about 45 minutes work. You can order the new ICs at the following link and they provide free installation instructions with pictures and also free online support with a support tech while you do the repair. I am one of their support techs. You would also want to order at least 4 convergence resistors and they send the proper ones for your model as often a couple resistors go. Your model uses 6.8ohm 2watt 5% metal film resistors. So to recap you will need (2) STK392-120 Convergence ICs and (4) Convergence ICs . very inexspensive repair if you do it yourself. here is the link. http://servicemanuals.vstore.ca/
Check the other posts for convergence problems. This may be what you're experiencing. Have you tried bringing it in with multipoint convergence? It's under Menu -> Picture -> Manual Converge -> Multipoint Red and Multipoint Blue.
