If you actually have a flat panel set, then the "fix" you list is not applicable. Those are for a standard CRT based Sony set. Can you please post the make and model of your unit. We can then look up the diagnostic code and provide you with a proper diagnosis and solution.

Thanks,
Dan

Tv won't turn on


High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits. 7 blinks to standby light indicates this. If you wish to get some details, http://electronicshelponline.blogspot.com/ Pull up older posts.

No Picture and Lttle red light next to power buttons blinks for about 30 seconds


First thing to do is reset ( see link below) and see if it resets otherwise if problem continues it will need some work

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. There are some common breakdowns in the High Voltage circuits in this set. One is the flyback transformer. Another is a small high voltage capacitor in the sweep corrction circuit. There is a cap that goes open in a high voltage circuit (C6532) which needs to be replaced.

Our tv turns off as soon as we turn it on. the red light blinks 7 times


Seven blinks = High voltage shutdown (overcurrent protection). The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits, otherwise send the TV to a workshop for a quote on likely parts and labour costs, then make a decision afterwards about whether it is economical to repair or not.

Usually it is either the flyback transformer, the tuning capacitors in the collector circuit of the horizontal output transistor(s) as well as the transistor(s) which could be faulty. These parts should be replaced at the same time.

Short-circuit horizontal output stage - hence the 7 blinks error code from the standby LED.

Standby light blinks 7 times and tv will not turn on


Hi,


Thanks for using FixYa. Standby light blinking 7 times means high voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. You’ll need to check power supply regulation and horizontal circuits. Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

Sony TV will not turn on. The standby light flashes 7 times. Whats wrong?


Hi,
Seven blink indicates high voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.
Also it can be due to bad flyback.

Hope this helps.

Thanks for using Fixya.

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
