TV won't turn on and standby light blinks 9 times... what can I do to fix this? Thanks, David


Nine blinks - Indication of shorted/leaky diodes - D6116 and D6301 on the "G" board. Panel Module Error or Thermal Error. Unless you are technically experienced, this can only be repaired by an authorised service centre. Obtain a quote for this, the parts are inexpensive, but labour costs might not be.

If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching IC regulator on the "G" board or check connections. Make sure the regulator is -12V or -13V (negative rail).

If the repair is done by an approved workshop, they will clear the error codes (standby LED blinks) as part of their 'soak-testing' and it should reset the TV back to factory condition. Remember to ask about what work was done and if the errors have been cleared/reset before you pay their bill.

TV has been working great for the past 6 years, this morning when turning on the TV nothing happens except the standby light flashes about 9 times on and off. No click like I usually hear when turning on...


Hi Dave,

We have had this same problem twice now - the first time under warranty (no problem) and now currently. The 9-blink error code refers to needing to replace two diodes on the G board. Specifically, D6301 and D6116.

The warranty time, the repair guy came and resoldered the new diodes onto the G Board, reinstalled the board, and was on his way. We had no problems for the next 3 years.

THIS time I ordered the two diodes from Andrews Electronics (www.andrewselectronics.com) am removing the G board myself and taking JUST THE BOARD to a local TV repair guy. This is a LOT cheaper than calling Sears or taking the whole TV to the repair guy. Here are the links to the specific diodes:

D6301 - http://parts.andrewselectronics.com/search/electronic-parts/parts/7/6-500-567-21.aspx

D6116 - http://parts.andrewselectronics.com/search/electronic-parts/parts/7/8-719-081-97.aspx

They are a heck of a lot less expensive than other places and the customer service I received was great!

I hope this helps!!

Tv wont turn on but blinks 9 times again and again


9 blinks is a ZCD error code (zero crossing detection) which means it is a bad g board. I had the same problem with this tv and have yet to fix it cause you cant find the board you need anywhere and most suppliers have boards that they fix themselves which only work for a month or 2 and then die. but you need to replace Replace D6301 on "G" board and d6116, d6117 i use 1n4148 for the little smt diodes, d6301 nte116 should suffice
it will be those few diodes and 15-20 caps on the am board if you choose to fix it yourself. here is a manual that lays everything out for you if you choose to fix it yourself. click here for repair manual
if you need further assistance please let me know and i will be glad to assist you from there. thanks and good luck

The tv wont turn on. the red light blinks 9 times.


There is a problem with one or two of the diodes on the G board.
Zero Crossing Detector 9 times 9:0 or 9:1
Probable cause • D6116 or D6301 is open (G Board)
symptom • No picture
I hope this helps and good luck!

No picture or sounds red light blinks 10 times


The parts you need are two diodes, D6301, D6309, and D6116, Sony part numbers 6-500-567-21 (D6301 and 09) and 8-719-081-97 (D6116), they are located on the G board, and that's located on the left side of the set, as seen from the back.

D6116 is connected to pin 9 of transformer T6101, and D6301 and 09 are in series off of pin 7 of that transformer.

TV will not come on. TV standby light blinks nine times continuously. TV is Sony KP-51WS520


Nine Blinks- Replace D6116 and D6301 on the "G" board, do not solder 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. Make sure the regulator is -12 or -13 (negative).

Re: Blinking Stand-By Light


This is the fix and it is not likely a do it yourself

Resolder D6116 & D6117 (Surface Mount) REPLACE D6301 (Do not just resolder D6301 REPLACE IT) Can use ECG116 (1N4004) ALL On G Board

Sony tv Model # KP-57WS520


A common problem for this error code is D6301 on the G board leaking under a load. D6301 is a Pt# 10erb20 -tbs.. This is neither an expensive part or that difficult for a quality shop. Kind of a no-brainer repair... But getting at the G board might be difficult if you don't have the technical experience. Personally I'd recommend taking to a shop if you haven't repaired many of these Sonys before..
Have a great day!
