My TV click on and off repeatedly when I try to turn it on...
I have a Sony Television and it started just clicking on and off when I try to turn it on. It never actually comes on now, just does this clicking thing and the picture stays on the screen for about 20 seconds. Is this something that can be fixed?

Try the 60 seconds unplugging of wall plug in your outlet. Or check your line if this have surge protector. Temporary plug your unit to wall outlet directly. Just check if it still within voltage operating range.
The standby light should be blinking a repeated count with a pause between counts. Can you post that here please? That will indicate the cicuit in which the problem was found that casued the shutdown. Armed with that info, I should be able to indicate the most probable defective parts and how to resolve the problem.
life safty should be 1st priorty before opening of TV set ;)
if you are skilled or qualifeid, then go-ahead and
if its Sony TV, you will see stand-by light blinking while tv try to power up. let me know how many time this light blinks.
When the set ends up flashing the LED, it should be a repeatable count. Can you please report that count here? Also, since the set eventually works, I'd suspect a bad connection or a part that has changed value over time. The blink code will help to narrow down the offending circuit.
If your Sony TV is hooked up to a good signal and is set up correctly, but only clicks and has no picture or sound, and even the menu will not show up on the screen, then it means that the main power supply has stopped working. I usually find that a small crack in the solder joint of the horizontal drive transformer or a shorted flyback will cause the large horizontal output transistor to short out, and this shorts out the switching transistors in the main power supply which then causes the Sony 0.1 ohm fuse resistor to open up. I have also seen power surges or power failures (brown-outs) cause the switching transistors to short out. In any case, the set absolutely should be serviced by someone experienced in repairing Sony TV's.
