in this set 3 blinks means lamp cover not set properly but i think that your problem is your 6x red blinks that means you have a problem in the audio section in your set(missing a voltage) or a themal fuse open.

Ths 5 blinks usually indicate an AKB problem. There is a break in the video path. I'll look up your specific model and post the results here. Please update this if you wish to attempt the repair yourself.

Thanks,
Dan

SOURCE: Sony 50 Wega LCD flashing red light

Hi

How many times is the red light flashing? The number of times the red led blinks means---


  • 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.
  • No blinks(Unit is dead) - Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open).
Please do rate this solution as FixYa and revert for further assistance.

Thanks

Please make sure lamp cover is fixed properly in its position after lamp replacement as it has to press a safety switch located nearby lamp cover.

Hope this will help.

TV WONT COME ON AND THE LIGHT KEEPS FLASHIN RED AN GREEN ON THE STANDBY BUTTON


  1. If your Sony Wega will not turn on, the front green light blinks, you hear a faint whirring sound and the green light turns red and flashes, it probably means the lamp inside the set is no longer working. If you noticed the screen beginning to dim in the preceding days or weeks, this most likely is the cause.

  2. If the green light flashes and the picture comes on momentarily but then goes off, and the green button flashes until the set restarts, then the seal around the lamp mount is loose and needs to be refitted.

  3. If the picture on your Grand Wega cuts in and out and the green standby light flashes, both of the set's STKs need to be replaced. STKs are small chips on your television's circuit boards and are identifiable by their labels. The specific STKs used in your Grand Wega TV will be identifiable by the numbered labels on top of the STKs.

  4. When you plug in your Sony Wega and hear a loud popping sound, it's probably caused by a defect in the high-voltage circuit. Let the professionals take care of this one.

  5. If, after turning on your Sony Wega, you can hear your set but the screen is black, you most likely need to replace your projection lamp.

Changed lamp and TV won't turn on, power light flashes 3 times


Hi,
Red light blinking 3 times shows problem with lamp cover.
Lamp cover is not fixed securely in your tv after lamp replacement. Lamp cover is first thing that was removed to replace lamp, check lamp cover and make sure its back in place properly.
Thanks.

Tv wont power up Standby light keeps flashing.


First step in any Sony LCD projector repair is bulb or lamp replacement. Fixes 95% of problems.

Taking apart and trying to measure things without a known good bulb is a waste of time and effort.
