Question about Televison & Video

1 Answer

1993 Sony Trinitron 27"

Will not turn on. No response at all. No noise, click, lights, nothing. The fuse in the back next to the plug is OK. Doesn't work with remote or manual power switch. Worked one minute and the next...dead (so I'm told). It is as if it were unplugged.

    Same problem on my 94 KV-27TW78...I had a power surge and had an outlet blow and even though the set was on a surge protector it will now not come on as is unplugged. I checked the bus as well and it looks to be in working order. Any suggestions on where I would find a free service manual for this model or advise on how to check the power supply?

    Mine is did the exact same thing two days ago. I also took the back off and looked at the fuse. The fuse is fine. I didn't mess with it anymore after that. I would just like to know if this sounds fixable or would I be better off just buying a new tv.

    Thanks, Rosie

As set is dead the problem is in power supply or horizontal section. though it is a simple &less time taking. but if you have no TV repair experience, or any experience tracing circuit flow with a schematic, call in a tech to assist you with this repair. This tv set is not the place to be experiementing inside of. You probably have bad capacitors and transistors in the power supply or the sweep power supply. Good Luck

Tv wont turn on only clicks and then flashes red timer light


Well, I have found out that the number of red light blinks is a "blink code" that indicates the nature of the fault with the TV. Usually these are various failures of internal fuses or circuit boards. There's a fair amount of information on threads at techlore.com on this, so try searching there. Teh specific codes and manuals are usually it seems under license from Sony and not available for free to the public. Sorry!

Sounds like you have a short in your set. Probably a shorted horizontal output transistor. You need to have a tech check it out and give you an estimate for repairs. Stargazer

T.V won't turn on


If nothing happens at all no lights no click make sure you unplug it for a while and try again the micro may just be locked up. If not also look at the line fuse, beyond that it will get pretty technical. May need a pro. Good Luck
