If you are using a cable or satellite receiver to tune your channels, they have settings that may be causing the problem. There should be a menu option for System Settings or something similar. Make sure that no type of Zoom has been turned on. Also ensure that your type of TV is set properly. If your TV is a Widescreen then make sure either that or 16:9 is chosen. If all of those settings are correct, and there is no Zoom feature is turned on your TV then there maybe an internal issue with the TV. You'll have to get a technician in to find the problem or check the internal settings that only he can access.

Hi,
According to the self diagnostic system 4 thimes LED blinking,
The fault is in vertical section, Vertical deflection is stopped, 15V not supplied (D Board), IC 5101 could be faulty(D Board).
Therefore check the above mention area it will help you.
Thanks for using fixya.

Diodes are blown on the G board ( POWER BD) replace the G board.

I think I can help you whit this, This is a common problem with the "G" Board (power supply) it will need two diodes one of them is a royal PITA to solder/handle and about 2mm long surface mounted(very small).

Yes, that's the G board.Replace D 6116 and D6301. 1 is on top of board and 1 is on bottom and very tiny in size surface mount type. You might want to order an extra of that one as they are easy to lose being so small. I have found the larger diode I think it's D6301 fails most often. Buy both but try that one first and test you may only need to do that one.

Could be something to do with your channels not tuned in propperly or your signal is being lost.

The d board is the center ( Tan) Board as shown in the pic below. You can get one at the following link. Just leave them a email with your model number and what you need if you dont see it listed as they only list a fraction of the boards that they have.

Yes It can be repaired!!
the problem would be the G board but I think is NLA so you have to send it to this company called PTS (http://www.ptscorp.com) so they can fix it for you

Ten blinks means, "HV Protection". The probable cause locations listed are as follows:

1) Q8014 or Q8013 have shorted replace alone with R8051 on D board.
2) IC8005 is damaged (D board).

I hope that solves your Problem, If so kindly accept it.
Thank You, Arjun.

Hello,
Please mention how many times standby light blinks on your KP-57WS520
There would be bit long pause between blinks so count the blinks and let me know to help you.

I've seen many of the same solutions to this problem, but do I dare take out the G board myself? Will it screw anything else up. You can't get a new G board anymore. Where do you get the diodes and how do you replace them yourself.

This is called a zero cross detect problem and has to do with the power supply. There are one or two bad switching diodes in the power supply

replace the zero crossover detect diode in the power supply
