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,

I have a sony wega trinitron, when the tv is turned on, (no visual, or sound) the red stand by light blinks 7 times, and you hear the tv click off? Please help


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.

Hi
In sony tv`s the 4 blink code(sony error codes)usually means that there is a vertical deflection problem.
It is often caused by a faulty vertical output i.c and/or related components. If you feel handy with a soldering iron let me know and i`ll help you with it.
Hope this help Merry Christmas
