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

I'm not sure which question will get posted back to you so I have provided the same "solution" in each. Please only update one.
Thanks.

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.

Sony trinitron kd-34xs955 standby light is blinking 7 times


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.
As you can see here, seven blinks of standby light is due to some over voltate at the final anode of the picture tube. This is a protection process that going on insde the tV circuits, to prevent more damage to other comnponents on board. The most common cause for this is with the main power regulator out voltage itself. If any way, it ahs exceeded 135VDC, this kind of fault will occur. Check the main power regulator section circuit for any damaged component/s. Replace all the small electrolytic capacitors there. Visit the site named 'Electro-help' for more details. Check this LINK and select the site named above. View it in 'Flip card' option, which can be selected from the drop down box menu at the left top corner or the display window. It will make search easy. Some times, the ads attached with each posts might help you to find the availability of spare parts. There are more than 550 posts to different brand TVs. Blinking codes and details are there.

I am getting 5 blinking red lights before going solid red; already replaced the projection lamp approx. 1yr. ago My Sony 50" KF 50WE610 model is about 7 yrs. old. Please give me some guidance


Hi dalposadas,

5 blinks of the standby led lights is an error code for no high voltage coming from the ballast board.
You have to check first if the supply voltage from the power supply is present feeding the ballast board. If yes, you have to replaced the ballast board. High chance that the fault came from it but you need to confirm it by the presence of the voltage from the power supply.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

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 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.

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

Sony Triniton Wega Model KV 32HS510. After pushing the power button,the tv starts to power up, then the standby light blinks 7 times then pauses before blinking 7 times again. It continues to do this,...


This is usually an indication of a failure in the scan amplifier sections. When the scan amplifiers or high voltage sections fail, the main power supply will usually also require servicing.

It is very common that the fly-back and high voltage multiplier and also the horizontal output stage fails in these sets. Along with it, the power supply will usually require to be serviced. On rare occasions, the vertical deflection amp fails.

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.
