Sony WEGA standby light blinking 4 times

I've had it for about 2 years already, and it's never behaved like this.

the picture comes on, and i have it set for vivid, and channel set at 4
for my cable box. however, about 30 minutes later, whenever a commercial
comes on, the picture blurs to black, and then the sound shuts off just leaving
the standby light blinking four times in a row. then if i turn it on again, it will shut off in 10 minutes when a commercial comes on. then it progressively gets smaller untill it shuts off every 30 seconds.

i've already tried doing a hard-boot, and letting it cool off for 3 whole days, and it didn't help. any advice?

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,

Hope this may help;

Regards,
VOTIT

KV-32HS510 and KV-27HS420, seven times blink error code shows problem in Horizontal deflection circuit.

There are many possibilities like dry solder joints, weak capacitors, Horizontal transistor short or flyback transformer fried etc.

If you have little experience of TV repair and good solder skills and have necessary tools to test / check defective parts, then you can make it. you also need to have related service manual to see board location, schematics and part numbers.

I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with
troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.

If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one
circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.

Problem with Sony FD Trinitron WEGA KV-32HS510 32" TV


Blinking of standby LEDs to Sony TVs are fault indications. Form the number of blinks occur at one time, the repairman can get an idea of the faulty stage inside it. According to you, it blinks 4,6 & 7. Just visit this site, It has details about blinking codes to Sony TVs, both CRT based, Flat panels and Plasmas. I can't provide more advice to you, because the number of blinks are not constant. Check the site, and get it.

Kv-32fs16, no picture or sound , red lights flash 4 times


Hi
In sony tv`s the 4 blink code(sony error codes)usually means that there is a vertical deflection problem.
It is often caused by a faulty vertical output i.c and/or related components. If you feel handy with a soldering iron let me know and i`ll help you with it.
Hope this help Merry Christmas

Sony wega tv was on and it shut itself off and we tried to reset power and the standby light is now blinking red 6 times with no picture.


Why not try this.

If it is a tube type.

1. Turn off the TV.
2. Disconnect it from the outlet.
3. Connect the power cord after 1 minute
4. Power the TV.

TV will not come on.


The 7 blinks indicate a high voltage shutdown (high voltage exceeded 33,000V). This is usually caused by a defective regulator. Could you please post the exact model number (KVxxx) and I'll look up the part you will likely need?

Thanks,
Dan

Blinking Standby Light


KV32hs500 tv won't turn on. Standby light blinks 7 times, stops and then 7 more times, etc.. The tv will usually come on after about 2 hours or so of being off. Plays fine when on but once it gets turned off the problem happens again. Any suggestions? T.V. is 5 years old.

36 inch sony wega trinitron


I had the same issue earlier this week. 4 year old sony trinitron wega 32 in. I was told by Sony to call technician to repair and have called tech....could be anywhere from $200-$300 repair. I did research the blinks (google "sony blinking codes" to find out what each means) Ours was 6-7 blinks which meant power surge to tv. I advised to Sony that i saw many of the same issues with many of the newer tv's and suggested a recall issue--they denied and where no help.
I will buy a new tv now--definitly not a Sony.
