Question about Sony KP-57WS500 57" Rear Projection Television
OK. I replaced the convergence amps but the picture is still 3D like so they are not getting power. How do I trace/repair the source.
There should be approximately 8 to 10 fuseable resistors around those convergence ics. They should stand out as they are a bright yellow colour. You should measure a short over them. If none of these are faulty I would leave the supply to the convergence alone and rather check the +5V / -5V and +12V supplies used by the convergence logic ICS. A common problem is the - 5V supply also used for your HT-protection cct op-amps. These ics goes short and pulls the supply to ground. There is no protection on these before mentioned supplies and therefore the set is still switching on but with a convergence problem.
Hope this helps.
