I take it this is a projection TV. so they use three lensed CRTs red green and blue. you should have a setup screen that projects a grid pattern. red green and blue. there is SOMEWHERE a adjustment that overlaps the three projected grid patterns. Making a WHITE single grid pattern. red green and blue make white light. Pin cushioning is the bowing. you may find a POT to adjust on the back of the set. I have no idea what set you have.
Lastly.. Pin cushioning can also be caused by faulty flyback transformers.
Hope I could help.. new here LOL
Happy Fixing =)

Bowed in at top and bottom and colors are separated


You have a convergence issue. First question in customer menu under setup do you have the convergence optioin? IF you DO NOT then chances are you have the fl231 problem. check under my profile in the tips and trick section. IF you do have the option try autoconvergence. if this fails(goes red screen then you might have a convergence power supply problem.

Check your screen. I have the same problem with mine. If the screen has a ripple in it, it could give the same effect.

Warped Picture, Separated colors


Each color (red,green & blue) has an amplifier IC (STK-).
When there is a convergence issue,the first step is change both
IC's for reliability. Then check for open fuses devices,usually
pico fuses.Then re-check convergence alignment.......T.

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.

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.
