Understanding Sony Television Blinking Codes

Many of the later model Sony TV’s have a built in self-diagnosis function. If the timer/standby indicator is blinking, this could be an indication of a problem with the unit. The diagnostic blinking will occur automatically with no action required by you to engage it.

The timing of the blinking you see would be as follows: two to nine blinks, (depending on the fault), about a third of a second apart, then a pause for 3 seconds, then the two to nine blinks about a third of a second apart again.

Here is a list of the problems that might have occurred indicated by the number of blinks. The words in parentheses are those, which you will see for each of these faults on a diagnosis screen described later in this article.

  • Unit is dead, No blinks - Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open).
  • Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.
  • One blink - not used for the self-diagnosis
  • Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.
  • Three blinks - 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.
  • Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505
  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.
  • Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.
  • Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.
  • Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.

  • 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. Make sure the regulator is -12 or -13 (negitive).
  • Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.

Intermittent problems? This is a great feature. You can also bring up these fault codes on-screen to see a list of the problem numbers with the abbreviation of the problem and the number of times this problem has occurred. This is slightly different than entering the service mode. To see the diagnostic screen, press the following buttons: Display, Channel, 5, volume 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 problems named, are 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.

Now that you know about these self-diagnostics, how do you use them? Say that you have a set with a black screen. You see that the LED is blinking four times. This would tell you that you have no vertical sweep, which is why the video is muted. If it was blinking 6 times, you would know that you have a horizontal fault. It's not a sure cure..

IMPORTANT: After you repair the unit, you MUST clear the values on this diagnostic screen. These codes do not reset themselves after the fault is corrected, so if you don't clear them, you'll be seeing "old" fault codes the next time you enter this screen. Clearing is done by going into the service mode (display, channel, 5, volume plus, then power ). Press 8 and Enter, which returns everything to the factory preset condition.

hi, if the sony bravia tv, SONY KDL-60EX500 POWER SUPPLY PSC10309E / G8S-E 3H315W

I have a source of that model
but I have no diagram, sorry


have same sony KDS-R60XBR1 After I changed the engine block projector, it show me up 3 time red led, but the lamp and lamp door is exactly could any one help me?
Great thanks

for each change of parts needed an upgrade, or at least try to full reset tv
disconnecting all test well to the antenna for at least 30 minutes and then again connect and switch

I am getting red green and orange lights that flash indefinitely. What could be the problem.

My 36in Sony2003 TV no longer turns on and blinks. At first it would take a couple of try's to turn on TV. Then it became more, now none and just blinks afterwards. Still has great picture. Is it worth to fix?

Hi! I've got a KDL40EX723 and the red light blinks 8 times. It's started yesterday and switched itself off about 5 times and wasn't really responding to the remote. I changed to new batteries as well so that's not the problem. I've done a factory reset then it was fine. Today evening it started again. So far in the last 3-4 hours only done it once then I've done factory reset and it works fine now. Any advice? Also I was trying to get the diagnostics menu up but I can't see a display button on the remote (RM-ED044). Please help me what to do.
Thanks

I own a sony nsx-40gt1 and its blinking five times. I changed out the power supply board and its still blinking 5 times. Is there a circuit diagram to show where Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board?

My KDL-32EX302 Sony TV set turns itself off after a few minutes of working.It shows six blinks for as a faulty code.The only thing we changed from the last time is our satellite receiver.Does it have anything to do with this or it has some internal problems??Appreciate any kind of help...

Sony projection TV when turned on plays for a few minutes then turns itself off on green lights about 40 times then turns itself back on. What can I do?

Where would I find "Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board"
Where is the D board???? How do I find Q8013 or Q8014???

I have a Sony KP 53S70 and it is not functioning. I was watching when I heard a pop sound come from it. the screen turned black and no longer works- no sound or video. It is about 10 years old and some folks have said that it is not worth repairing. Since I do not know what the problem is, do not know if I can repair ( or have it repaired), I don't want to take this step yet. Can anyone there help me? JohnC

On klv-40v400a on start green led comes on then red led flashes 5 times what could be the problem?

Hi was just given a Sony wega kdf-e50a10 and it turns on for like 5-10 seconds then turns itself off and the red light on power/standby blinks 5 times pauses and repeats. What do I need to do? You have a manual or steps how to fix this? It came with original remote but no manual. Any help would be great thank you.

Bought a SONY Bravia KDL40XBR9 new about four years and watch it about three hours a week, total. Wife wanted Amazon streaming so I configured and connected a Netgear WNCE2001 WiFi LAN directly into the set. I've read many folks have used this as opposed to Sony Dongle with great results. First I updated the firmware successfully with thumb drive in USB port. Got all three OK's on the network report indication network connection etc., then downloaded internet content that I watched, in this case, a couple of You-Tube videos but all the widgets from Yahoo and the other streaming channels were there. Went to go to Amazon box to get the code to register and the set had no internet content and asked me to download it (again, I guess) went into download mode and suddenly stopped and went into the three cycle on/off and 10 blinking red lights. Did a power reset, same thing. Did a factory reset with arrow up button on remote and power on from the set and same on/off three times then 10 red blinks. Repeated this 5 times all same results. Help, please. I dropped the unit off at a repair center that an acquaintance owns but he does not have the drive to plug into the back for diagnostics. Any help would be greatly appreciated. By the way, could the netgear wifi adapter or the firmware update have caused this? Unit was amazing for past 4 years. Did this and poof! Thank you in advance

I have a sony 50 inches LED (model 50EX645). It has a problem no video and red light blinking 6 times. Please advise how to repair it.

Thanks,

I have a sony wega sxrd projecton lcd tv. When I turn the tv on the screen stays black and the green standby light continuously blinks for awhile then the red lamp light blinks 12 times then continuously blinks.

Can anybody show me the location of the IC 1509 & Q 1505?

My Sonys recently started this little party trick. It clicks twice when you switch it on and has picture or sound,
It then decides to pique your attention with its little flashy idiot light. Subliminally forcing you to mentally count its morse code style message.
Hmm, mes thought. Whys it doing that?
CLICK CLICK, FLASH FLASH now knowingly taunting me with its peekaboo secret signal.
So, I thought, Where do you turn to for info on decoding said signal?
Aha. . . Interblag !!
If its been spotted doing this kinda behaviour in other telegrottos before, Then thats where I might find some sort of insight into amending this delinquent mischief...
And so in the time it took me to come to this revelation. The fuckin thing throws me a curve ball by silently sneakily switching the screen back on !!
But by this time I have stumbled onto this little goldmine of listed / filed Sony Tv foilables. . .
So if you have 2 clicks to 5 flashes you might just try a bit of patience after powering up your tempsemental tv and mentally tick off about 25 flashes, low and behold you should witness it sidle out of its hidyhole and then youll be hiding behind the sofa while Doctor Whos on. . . !! :-))

sony grand wega 56 inch I think new bulb but green light turns on a few seconds, no pic no sound, (I don't even think the fan turns on)and then it blinks red start/standy button 10 times over and over. HELP, please, disabled, too blind to watc smaller tv w/o this large screen,5 year extended warranty expired long time ago.

I have sony LCD Tv , Model KLV 32V300A. onc ethe power is set to ON, the green led is lashing for once then remain in solid position for 9 seconds. again flash for once and remain solid for 9 seconds. what wouldbe the cause and let me know the remedy. Regards

I have sony bravia KDL-55EX720, the red light blink 2 times. What can I do?, can I repair it myself.

I have a KDL-60EX500. When u turn it on. Sony icon blinks on and off 3-4 Times with no picture then red light continues to blink in increments of six repeatedly. Getting electricity to tv but most power supply board outflows have no output by using meter. No power in to inverter. When tv is powered on there is a clicking sound coming from power board when sony icon blinks on. Any ideas?

I don't understand what these things are will someone explain them to me plz?
Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206

Hi, i have sony bravia tv 32 inch model number KLV 32V400A. it keep blinks for 8 times then repeat again. may i know what the problems? thank you.

What does the One Blink mean?? Whats it used for.. is my unit sleeping?
I have no pic or sound with the 3 red blinking lights. I have researched and hopefully nailed it down to the OVP? My question is what board does that correspond to and are there more troubleshooting steps I should explore before trying to replace anything.
