Your main board doesn't have to complete replaced, however your power supply module is the culprit and should be replaced.

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

    Your horizontal output transistor (HOT) is busted already,you better replaced
    it with identical rating,so it will works better again,if you have a
    knowledge of electronics,you can do it yourself.If not find a TV
    repairman to do the repair for you or bring it to a TV repair shop,
    maybe they cost you $100 to $150..



    Hope this may help you.

Sony Trinitron color TV 36 inch


hello,

You should examine the input power of the TV. If you dare to open the back of the TV You should examine the by using the tester to test the continuity of the voltage input of the TV. i guess voltage regulator need to be tested.

Be careful high voltage inside the TV.

The best way is to contact the vendor of the TV or sony service center in your area.

may this help,

Stand by light blinks 6 times, wont power on


Here you find sony blinking codes

SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking selfdiagnosis
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.

Good day,

Your problem indicates that there is an issue with the horizontal or vertical circuitry. Some parts may have been busted thats why your tv cant function normally.
I suggest you have it checked by a repairman,

Good day.
Flyback could sometime be a problem but seldom that its the source. Have your circuits be checked first particularly the vertical section. Also, check on the supply of your system IC. there may be some imbalances there.

Response is highly appreciated.
