    Same problem, light blinks constantly, but no way to get the picture on via manual or remote. Even my teenagers can't figure out a way to get it on.

Starkrayving, this dont even have a light bulb in it. I can't believe some people that think they are techs on here. but i guess give everyone a try. lol how about a hands on tech that has fixed several sony's answer your questions.... follow this link. and follow the steps. one thing that may not be listed is adjusting the screen control on the back of the flyback a lil bit. if you think its on but no picture and the light is blinking. this is a sure sign of the tube getting weak or the flyback. you could get some time out of it if adjusted. everyone else follow the link.

I think we had this problem and it meant that the Light bulb inside needed to be changed. You order it from Sony. It costs upward of $200 but fixed the problem for us.

SOURCE: my sony trinitron will NOT

If you let us know how many times the light blinks, that will let us know whereabouts the fault area lies. Her is the list. I hope it is helpfull.

  • 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.

My sony trinitron television will not turn on. it will click and the stand by light blinks, but there is no picture. can I fix this?


It sounds that there is a direct short circuit in anywhere in circuit board. Most probably, it might be to vertical sweep output section, in Sony TVs. Here you noted that the standby light blinks. Blinking of standby light to Sony TVs are fault indications. Count it, and check this.

1 Answer

Sony trinitron


Need a little information here...

1. The TV remains on, yet there is no picture and no sound? Or does the TV turn off altogether?
2. Are the blinks constant and continuous? Meaning, does it blink two times, pause, blink two times and go on and on like that?
3. Can you turn the TV on? Or can you not get it to turn on?

Answer those questions and I can give you some more information or send you to the place where you can get it.

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
