Question about Toshiba 32AV502R LCD TV

1 Answer

Toshiba tv no power

I have a Toshiba 32AV502R LCD HDTV. After my home's power went out and the power came on, I cannot turn the television back on. Do you have any suggestions. Some sites say that some Toshiba televisions now have a full power down button which may be the source of the problem. Does my model have such a button? Thanks.

I have never heard of or seen a "power down button". Unplugging the TV and holding the power button for a minute or so sometimes will do a hard reset on the TV, is that what you seen?.
On your problem, chances are there was a spike that came down the power line when your power went out and it took out at a minimum the main fuse in the TV, you can remove the back and replace that fuse on the power board and see if it comes on or blows the fuse again, if it blows then look for a bad rectifier or shorted FET transistor in the hot section.

What type of fuse does a Toshiba 32AV502R LCD TV use?


It is Sunday and I am not at the shop to look it up, but I am yet to see a power supply board where fuses are not marked on the board itself.

Meaning that the answer to your question is on your own board.

Also, I have very rarely seen a fuse go bad on those power boards.

It is not impossible, of course, especially if you short it out manually, but unless you did chances are the issue is something else.

Toshiba 32AV502R won't turn on even though green light goes on


Try changing the input device to something you are sure works. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

When power is applied Toshiba 2av502r cycles on and off contineously.


It can be that the power supply is sensing shorts circuits so it goes into turn off/turn on cycle. You need to look inside. It can be the power supply module may have failed due to bad caps.
