Question about Sony KP-46WT510 46" Rear Projection HDTV

1 Answer

A WEEK AGO MY KP51WS520 SONY TV STARTED TO TAKE AWHILE IN THE MORNING TURNING ON. THE STANDBY LIGHT WOULD BLINK 9 TIMES. MONDAY MORNING IT WOULD NOT WORK AT ALL STILL BLINKING 9 TIMES. GOT ON A THREAD THAT EVERYONE WHO HAD THIS PROBLEM FIXED IT BY REPLACING THE G BOARD OR SOLDERING THE 2 DIODES THAT ARE ON THIS BOARD. I ORDERED THE BOARD AND REPLACED THE OLD ONE. NOW TV JUST BLINKS 3 TIMES AND WILL NOT TURN ON STILL. I KNOW IT HAS TO DO WITH THE POWER SOMEWHERE JUST CAN'T GET A GRASP ON WHAT IT IS.

    WHEN I PUT THE G BOARD IN I WAS GROUNDED, ALSO THERE ARE ONLY 4 CONNECTIONS ALL PLUG IN THERE IS NOT TOO MANY WAYS I COULD,VE HOOKED THE BOARD UP WRONG. SO I AM KIND OF WONDERING HOW IT COULD STILL BE THE G BOARD. IF THE 1 I WAS SHIPPED IS GOOD

  • bullit25 Jul 16, 2009

    WELL BY NOW I'M AT WITS END. I HAVE 2 G BOARDS 1 BLINKS NINE TIMES AND THE OTHER BLINKS 3 TIMES. AS I SAID THE NEW REFURBISHED BOARD CAME SEALED STATIC FREE BAGS THE WHOLE 9 YARDS. AND I WAS CAREFUL AS I SAID I GROUNDED MYSELF AND HAD RUBBER SOLED SHOES ON. I HOPE THEY DID NOT SEND ME A BAD BOARD. IT HAS TEST STICKERS ON IT. BUT I HAVE THROWN IN THE TOWEL AM NOW WAITING FOR REPAIRMAN. SUPPOSE TO BE HERE AT 1 IT IS NOW 4:15 BUT HE PROMISED HE WOULD BE HERE BEFORE 6. HOPE I CAN GET OUT FOR A COUPLE HUNDRED. OR IT'S OFF TO BUY A NEW TV LOOKING ONLINE NOW FOR $$, RATINGS, TYPE. LOOKS LIKE LCD LED IS THE WAY TO GO. YES?

    THANK YOU FOR YOUR HELP

    HAVE A SET OF SONY BLINKING CODES HERE I GOT ONLINE FROM SOMEWHERE A LITTLE DIFFERENT THAN YOURS IF YOU WOULD LIKE I CAN E-MAIL THEM TO YOU.

    that can be possible.many a times the faulty boards get delivered.but its 50 --- 50 chance.sometimes the companies get it replaced it for you.sometime they reject the replacement.mostly if its not any physical damage or any short circuit they replace the board.but if its a bit short circuit which is not seen by you with naked eyes but in the board detecting machine they directly get it checked if there is a minute short in the board after connecting.

    but for better help.get the board checked at local tv repair shop as they have such types of machine.it will be confirmed in sometime is there a short circuit.also take the model number of tv with you and ask the technician is the board compitable to this model number.this will be help full.

    thanks.thanks.please do rate the solution.thank you for using fixya.keep updated.

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.

Trouble code: Standby LED blinks 9 times


Try pushing the buttons on the remote and let me know what comes up on the screen if anything.
Display, Channel, 5, Vol Minus, ( Not plus ) then Power. This brings up
a screen with a list of the problems and number of times they have occurred.
Each of the problem names is abbreviated as, "OCP", "OVP", "V STOP", ETC.
We have repeated them in parentheses in the text for the "Blinks" described
above so you can correlate between the diagnostic screen and the blink
codes.
