Trouble code: Standby LED blinks 9 times

I have a sony wide screen projection tv model # KP51WS520. After recently rearranging our living room; we moved the tv to the oppisite side of the room, the tv doeen't come on. Instead the standby LED just continueously blinks 9 times then pauses for about 3 seconds and then another 9 blinks. If you continue to try to get it to come on it eventually will turn on and everything works just fine. Somtimes it takes 5or more minutes of pressing the remote to get it to come on.

    Sorry I haven't replied back sooner. I tried your sugestion Without any thing happening. Does the TV have to be on when you do this?,because I can't even get it to turn on today. Do you mean to sequence through these buttons re: push display then push the 5 button then vol minus and then the power button, or do you mean to push all these keys at once?

  • tinmandave Jan 15, 2008

    OK, I got it to turn on finally & it lists #s 2 thru 10 they all are zeros except 9 which says ZCD 255 so what does this mean & how do I get this self diagnossis display off the screen? Any help you can provide is much appreciated. Tinmandave

  • tinmandave Jan 15, 2008

    Yes I'm positive that it blinks 9 times. My Sony is a model KP51WS520 it's about 3 yrs. old. The display reads like this

    2: +B OCP 0

    3: +B OUP 0

    4: V Stop 0

    5: AKB 0

    6: Low B 0

    7: H Stop 0

    8: Audio 0

    9: ZCD 255

    10: HV Prot 0

    101: WDT 0



    I found someone with the same problem on another site and they were told that the problem was with 2 diodes on their G-Board. I don't know if I have the same problem or not ,I was hoping there was a simple solution.

  • tinmandave Jan 15, 2008

    No I don't have a service manual. I just moved the set from one side of the room to the other and then it started doing this. I thought maybe moving it had something to do with it,like maybe it shook something looose.

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.

    Sequence through the buttons that should put your set into self diagnosis. And list the problems on the screen

  • Sonny Berry
    Sonny Berry Jan 15, 2008

    Okay those are the code that says your diagnostics doesnt detect any errors. Youre positive it blinks 9 times? Cause Sony is supposed to only go to 8 blinks. To clear your diagnostic screen just push the power button off, this will get you out of diagnose mode. Count your blinks again then let me know.

    Sonny Berry Jan 15, 2008

    Thats a good possibilty. Because sony is not susposed to blink 9 times 8 is the most. So you could very well have some bad Diodes. Do you have a service manual for this set

  • Sonny Berry
    Sonny Berry Jan 15, 2008

    You probaly just have a loose connection from moving it. Its probaly a real easy fix. usually just moving them doesnt cause Diode failure. Probaly a connection on one of the modules.

Is it a problem of the inverter board ?


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
http://electro-medical.blogspot.com/
If blinks continue without any pause, the main board is faulty.

Sony 3lcd wega engine tv screen turns black, power/standby button blinks 45 times, then screen goes back on. This repeats over and over again. Do you know what's wrong with my tv? Thanks.


First check your tv if it has standby power. if it has standby power please do count the number of blinks of red led. (it is on a sequence) so that we can walk through the steps and procedure to get rid of the trouble. if theres no stanby power, its probably the power supply. please do check busted fuse and replace with same ratings.

My Sony Trintron's LED Light blinks 9 times when I try to turn on the set


  1. 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). If you wish to get more details about the blinking codes to Sony brand TVs, check this link. Pull up older posts there.

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.

count the flashes again carefully, as that model should only blink a maximum of 9 times, unless your getting two seperate codes. Try counting and trying to notice if it pauses a second before blinking again. then let me know what you discover.
