    PT-53WX42F - I have the same problem. There are two convergence settings - the first gives you a huge cross hatch across the screen, but I can't get it lined up...the line stays wobbly so some parts of the screen give a red and green shadow.

I'll second the original fix recommendation. I just did this to a 47WX42F - I replaced the STK392-110 convergence ICs with STK392-150 parts. The STK392-150 is a higher rated part than the 110, so hopefully it should last a little longer. You should also make sure that none of the power resistors feeding to the Convergence ICs (they sit right in front of the ICs and are 2.2 Ohm parts) have burned or opened up...replace them, if damaged, too. None of mine were damaged, though. Other recommendation is to get Hitachi STK ICs, not a knock-off version.

Joe,
It sounds like your may need to replaced your convergence ic's loc# ic7001 and ic7002 stk392-110. That should take care of your alignment problem.

Picture suddenly went out and the lamp and temp lights in front circle are blinking.


Hi,If your tv is between 2-4 yrs most likely it's time to replace the lamp.If you hear continuous clicking it could be the ballast which is the board that powers the lamp.If you hear buzzing it could be the color wheel,which is a spinning wheel that creates the color on your tv.God bless you!

RED ARCH ON LEFT BOTTOM CORNER


This is a very common failure on Projection TV sets.
  • 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.
You can see some example photos and find a solution here...
