Replace the mainboard, you can find it on Ebay, the price range is wide, but if you post your brand, model and product code (back of the TV, where the serial number is) I can narrow it for you.

I have a sony kp57ws520. The set wont turn on and the lite blinks 9 times. I was told at one time to solder two specific diodes on the g-board and that worked for a period of time. Now the problem is back....


Resoldering those parts is known as a temporary "fix". Those parts need to be replaced. I believe that they are D616 and D6301. Both are on the "G" board. I don't have a listing for your specific model, but most of thr 57s are similar.

Keep us posted.

Philips 42PF7320A/37 won't power up Led blinks 7 times


This what to do measure from the logic board which is located under the small signal board and have the AV jacks connected to it. If the voltage is 3.1 or close the problem is with the power supply or a boar connected to the power supply. Unplug the set. Disconnect the Y main board first that will be on the left side of the set facing the back. Plug the set back in if the led is solid replace the Y main and the Y upper lower. If still blinking plug the Y main back in and unplug the X main which is on the right side facing the back. If the led is green replace the X main. If the led is still blinking replace the power supply.
But if the volts are 0 the problem is the SSB or the logic board. In that case take the (SSB) small signal board out the set and place 1 jumper on J8003 and another jumper J8004 of the left side of the power supply. Then place 1 jumper on CN2072 of the lower left part of the logic board. Plug the set back in if the set displays a white, blue ect screen replace the SSB. If not and on the logic board you don't have 1 solid blue led and 1 blinking led data is not flowing and change the logic board.
