Question about Sony KP-57WS500 57" Rear Projection Television

1 Answer

Sony kp-57ws500 Alright so I have a couple problems that I am really needing fixed. First what board should I replace when I get the seven blink code error? or is there anything i should check and see to replace first. Second the cap off one of the guns came off and leaked coolant, I dont believe it leaked onto the board BUT if it did it only leaked on it a little, where would be the best place to buy coolant, because i dont want to start it up without that in there? I am begging for help here cause I would really like to get it running again!

You can get coolant at a electronics part store if there is one in your area, does that tv have a g-bd on the left side looking from the back?  that also might be your 7- blink problem

The tv goes on stand by mode by itself. My 57' sony does not turn on but remains in stand by mode. Blinks 9x then stops, then starts all over again. What needs to be done?

9 blink in your Sony KP-57WS500 shows error / problem in Audio section.

1= +19 volts &-19 volts are shorted by any reason on A and B board.
2= IC708 is faulty on A board
3= PS701 & PS702 (fuse) are open on A board.

Above are possible reasons of 9 blinks.
If you have electronics knowledge and have tv repair skills then check as per above info. otherwise I recommend get help of TV tech person or contact nearest Sony service center.
Thank you.

Six (6) blinks on the Timer/Standby led

6 blinks means lamp thermal fuse blowing, replace thermal fuse.
