Hi...

Three blinks means- B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.

Thanks
Smith

The blinking standby lights are an internal diagnostic code. The 3 blinks usually indicate a problem in the power supply area. Since the problem changed with the new board, you may actually have a couple of problems. This is not a problem that is easily diagnosed remotely. If you have no experience repairing TVs, I would not suggest starting here.

Check the regulators on the power supply board, specifically looking for bad solder connections. Repair any of those that are found and update this with the results. I expect the behavior to change.

Thanks,
Dan

Stanby light blinks 9 times after powering on but no picture


  • Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections.
Hope that helps.

TV won't turn on


There's a small diode on the power supply board that causes this. Its identifiable by its purple stripe. You will need the correct type of diode to fix this properly. The diode supplies the standby voltage to the system control circuit, so when it fails, the TV will never come on.

57 "SONY, DOES NOT TURN ON BUT STAND BY LIGHTS BLINKS 9X, THEN STARTS OVER


Hello,
I dont think your unit has big problem.
1. 9X blinks means 9 VDC supply is shorted either in A or B board.
2. IC708 is faulty in A-board
3.PS701 or PS702 is opened in A-board.

Dont forget to Rate!

Good Luck

Sony Wide Screen Projection TV KP-51WS520


I had the same problem. blinking 9 times, pausing, 9 times...... remote would not power the tv on. after five minutes of pressing the remote it finally would. after turning it off you would have the same problem. sometimes a half hour of pressing remote in every which what way. finally left the tv on for three days and would mute at nite to go to bed. didn't think that was the best way so turned it off and it never turned back on. checked all the forums and found out it was the g board. unfortunately, you cant buy the whole g board anymore. if you take the back panel off the tv, on the lower left corner is where the g-board is. there are 3 little things to unplug and two screws (phillips head) in the middle of the g board. its simple to figure how to take it out. go to the sony direct parts website. the part # is A1054157A for the g board. since they dont sell it anymore they have a phase 3 program where you send in your old g board and they repair it for 64.95. it'll cost about 8 bucks to ship it to them. better than the 400 bucks the tv guy wanted. address is sony customer satisfaction ctr. , materials door 27H, mount pleasant, PA 15666 there number is 866-748-8272. call first and they give you the step by step instructions what to do. after tax and shipping it came out to less than 80 dollars.even came with a warranty. got it back in a week, popped it in and just love turning the tv on. anyone can do it.
