I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with
troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.

If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one
circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.

This is a problem with the regulator circuit. If you are comfortable with soldfering, you should be able to repair this yourself. I'll look up the specific parts that require replacement.

SOURCE: Sony Wega 40" TV will not turn on, standby light blinks 6 times repeatedly

Hello,For model KV-40XBR800,

Pls check following area.

Low HV Shutdown:
On the D Board.
Check IC8004/pin 7 should be 7.4v.
Check IC8006/pin 2 should be 2.5v if lower will trigger shutdown by causing pin 1 to turn on.
Check IC8006/pin 3 reference voltage 2.2v.
IC8006/pin 1 normally at 0v. If high
turns D5007 ON which turns the latch circuit Q6532,
Q6530, and Q6527 ON and turns the AC relay RY6501 OFF.

And NOTE: 6 blinks also can be Low B+ protection.

Unregulated 7.5 v from the power supply to 5v reg IC504 on the A Board. 5v to M Board Q2314

to CPU IC2300/pin 43. If 5v missing set will shutdown with 6 blinks.

Good Luck

Hello maymet,

This sounds like the HV protection circuit is cutting off the TV due to a high current event in the set. This could be a problem in the High Voltage section of your TV (Horizontal output transistor, Integrated High Voltage Transformer, and y of the deflection components, and or the CRT in cases of shorts).

I would suggest that if you do not have a background in electronics, you should have an experienced TV technician troubleshoot and repair this problem.
This is due to the nature of the dangerous voltages that are present in the television.

I hope this helps,

Thank you,

Shuttle83

Sony wega trinitron won't turn on


  • 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.

    If a red light flashes for more than a few minutes,disconnect and reconnect the power cord.
    Check the TV/VIDEO settings
    make sure you have inserted the batteries correctly to remote control.
    Try another channel to rule out of station trouble.
    if the problem continues may be a power supply problem.
    good luck ! please dont forget to vote if this suggestion is helpfull.
