Hi there, we have a sony KV-30HS420 30 inch fd Trinitron that is blinking 7 times and then shuts itself off. We can turn it on again but this problem is understandably quite anoying. What do you think...


There is a power supply fault causing the EHT to rise above 33KV.

High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.
Hope that points the engineer in the right direction.

Timer button blinks but doesn't turn on


There are several faults that can cause this. Shorted diodes in the high voltage, a bad flyback transformer, a shorted CRT driver IC. None of them are very easy to fix.

KV-36XBR450, FD Trinitron WEGA


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,

TV Blinks 7 times


The 7 blinks indicate a safety shutdown due to over-voltage in the high voltage section. The high voltage has exceeded 33,000V. This is usually a problem with the power supply regulator. I need to look up the specific part for you. If you are comfortable working inside the set and can solder, you should be able to repair this yourself.

Sony KV Trinitron WEGA 36" TV won't turn on


My 36 wega did the same thing last week it must be contagious. Blinks 7 times mostly but sometimes 6 if hit power switch again. The problem is the D-boards shorted Flyback high voltage transformer but the ones Sony is selling $130 do not hold up and seem to burn out in a few days, yes twice bitten. Finally they send me new D-board can't wait to see if this fixes it once and for all. The board costs around $200 but is worth it to get it running again.
