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.

It wont turn on it blinks 7 times can i fix this


Hi there.
In sony tv`s the seven blinks code(sony error codes)usually indicates a high voltage shutdown(t.v has exceeded 33k volts). That is often caused by the power supply regulation and/or horizontal circuit fault.
Hope this help Merry Christmas

Stand by light blinks 6 times, wont power on


Here you find sony blinking codes

SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking selfdiagnosis
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.

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.

TV Sony Trinitron won't switch on


There is a problem in the set, the blinking l.e.d is numbered by way of the number of blinks. It might be your IFT, better known as your high voltage transformer, those codes helps the tech isolate where the problem most likely is.

TV's always make a clicking sound as the Main Power relay turns on. If you are asking why it then doesn't turn on, it can be many things. The processor monitors a number of circuits and if something is amiss, it turns off. The most common failure is the high-voltage circuit and if the set is any where near 10 years old, I'd plan on replacing the flyback transformer as well as anything else it damaged while failing.
Another option is to wholesale replace the main board from an outfit like PTS Electronics at ptscorp.com.
Hope Ya Fix It!
