Re: Set will not turn on

If you're NOT still under warrantee you should at least open the TV and look for a blown fuse near where the power cable enters the set. A lot of times you can buy replacement fuses at a local electronic or hardware store and they're easy to replace. Check the fuse. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again, or if it is not blown, your problem is probably in the 'X' volt regulator and you will need professional help with the repairs. good luck!

The TV will not power on at all


Is the set completely dead? if so you should see no indicator lights and hear no "click' when the power button is pressed. If so than the only thing wrong with the set ic the main Fuse (6.3A 250VAC) has blown.

1993 Sony Trinitron 27"


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

Red light blinking


If the tv is a dead set with only as you say the red light blinking, then your tv has a defected power supply or related circuit.if the screen light up with no sound then the tv is having a problem in the IF circuit or also the power supply.in either case you will have to call a tech to look on your set to repair it.good luck

Remote won't turn set on anymore!


Hi Smittie, I had a similar problem with another type of TV set. All functions work well except power. The solution was to replace the batteries, perhaps they are running low. It will also reset the remote which might help as well. Hope this will work for you too. Cheers.

TV won't turn on


If the TV wont go on with the manual button on the front panel, then you have an issue with the tv set. Try a differant wall recepticle. Or unplugging it overnight. If it wont go on with the button on the front of the set after this is tryed, then its time to go to the repair shop, as the set has a power supply problem or a problem in the HI voltage/sweep circuit. Good Luck
