Hi,
Let me know do you have related service manual of Sony KP-57WS500 to guide you further?
Without service manual it would be difficult for you to understand our directions like what to check and where to go in TV etc.

Bad IC is my guess...

On anotehr note convergence 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.

Convergence


Seems like you need to replace its convergence amplifier ICs (2 pcs). The convergence amplifiers are attached vertically to two heatsinks. When replacing these, remember to reapply thermal paste (white paste for better heat transfer from IC to heatsink). If you don't replace these, over time other components will be affected.
