I have a 2004 Sony Wega Trinitron KV-HS510 that will not turn on. When I try to turn on the TV it sounds like it will power up and then I hear a click, and the TV turns itself off. The Stand By Light is flashing 7 times then pauses and then flashes 7 times again.... Any idea what the problem is or what the cost will for getting it fixed as most in house techs are charging $100 to $150 just to walk in the door and tell me it doesn't work... Thanks, Andy

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.

Please replace Horizontal Output Transistor in KV-2167MT and TV will start function.

Hold setup button on remote while pushing the ON/OFF button on the TV at the same time. It worked for me. Here's the website I got this from: http://www.kb.sony.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=http--esupportsonycom-perl-tutorial-displaypltutid297templateid1regionid1KSMFlag7370&sliceId=&docTypeID=DT_TUTORIALS_1_1&dialogID=53101564&stateId=0%200%2053105132

how do i adjust the brightness if i dont have the controler?

Hiii...
I'm not certainly sure how many time the led blinking ?

I hope hear from tou soon...

Thank's

i dont think its HV
3 blinks is B+ voltage.

just replace the main board.
sum times andrews electronics has them for around $80

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!

tv is in protection mode...first u most measure psu output, next horizontal transistor driver, and all outupts from flyback....and find witch one is in fault

I get a black screen after power on...then a bright white light in the middle of the screen.Then the red light flashing and turns it self off.
