Question about Sony KP-57HW40 57" Rear Projection Television

2 Answers

Concave picture with rainbow effect at the edges

I have a 4-5 year old Sony KP-57HW40 57 in. Rear Projection Television. The TV suddenly developed a concave picture (i.e., the picture looks "bent" or caved inward), and there is some serious rainbow effect at the left and right edges of the screen. It happens with any input source (cable, DVD, XBOX). I checked the automatic convergence on the TV, and it is converged properly. What might be wrong? If it needs a repair, roughly how much would it cost? I am trying to sell the TV and get some money out of it, but I am not sure if I should repair it to get a little extra money or sell it as is at a lower price. Thanks.

IF IC1606 AND IC1608 ARE THE CONVERGENCE ICS, IT DID NOT SOLVE THE PROBLEM. STK 392-560 AND ALL THE 100 uf CAPS WERE REPLACED. THE GREEN CONVERGENCE IS CONCAVE RADICALLY ON THE TOP AND BOTTOM, LIKE A HOURGLASS. LOOKS LIKE THE GREEN CONVERGENCE CIRCUIT IS NOT FUNCTIONING. NEED SCHEMATIC TO GET ON SCREEN ADJUSTMENT CODES, TO SEE IF IT WILL ADJUST OUT? GEORGE ACE TV CENTER HENDERSON, NV 702 382-2340

My 12 year old Sony KP-53V80 TV suddenly turned off and will not show a picture just a small rainbow at the top of the screen, then a whistling sound, crack and turns back off. can you help?

sounds like the inverter went bad...There's a high voltage device in there that runs the whole "picture" thing. There are capacitors involved with it that have probably failed leading to this mess.. That would be what that "crack" is...If you try to turn it back on does it just "click " and then stay off?

Picture is concave and red, blue, green rainbow shadows objects on the screen.

This is and indication of convergence chip failure. two stk-392-560(ic's 8002,8001) and their assocated bell fuses. Our shop generally charge around 150 for this repair. But prices vary with shop.
