    all steps to the end to exit. It starts with the B parameters, then C,
    S, and M, then you can exit by pressing power and action ON THR RECIEVER
    for 2 seconds. The TV will turn off and come back on on ch3 with sound.
    BTW, you advance thru the menus by pressing power on the remote. )

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.
