try the hard reset method , that is, unplug all the cables and wait for half an hour , and replug all cables and try ......hope this will help you

Yes,this problems is 100% convergence problems,it dead.The tv have colors lines R,G,B mis alignments anywhere in the pictures,have colors shadows pictures or 3D pictures look alike?The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors too.These parts on the tv convergence board,must be replaced to solved the tv pictures convergence problems.The shop,will cost u like $300-350 for parts and labors.

100% Ur 2 STK convergence ICS are still dead.Ur ICS soldering some how,u got the ICS shorted.Or ur ICS not right kind of STK ICS,u replacing in ur convergence board.

You can get complete convergence kits from www.TvRepairKits.com

STK-series integrated circuits are amplifier IC's that are most often used in projection TV sets as convergence output amplifiers. When these or other convergence parts fail, the three color images no longer line up correctly on the screen.

Your TV most likely has a Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.

Solution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.

replace the stk-392-110 (x2) and any burnt resistors. cost 20$

may not be convergence may be a bad stk for convergence if that style if so try stk

if you can remove the rear panel assy. look for the convergence ic's they start with stk--- and you got the part number you need a source panasonic is 814 source and the number on the ic's stk 390 ----/
