Question about Toshiba 50H82 50" Rear Projection Television

1 Answer

Had a "low power" problem in the wiring in new house, got the wiring fixed, but TV didn't fare so well. It now has the blinking red light, but power doesn't come on. Is there a fuse, or something else that can be replaced to fix it?

TV have power, but when turn it on, the red light blink a few time but no display.


It sounds like a bad circuit or outlet. Replacing the power supply will not fix it. Try measuring the voltage with TV on. Try it again with an electric iron, waffle iron or something like that plugged in. You should not sag by more then 3 or 4 volts. Be aware this may cause a wiring fault to fail and could cause a fire. If you get a large voltage sag turn the breaker off and get an electrician.

The infrared receiver light just keeps blinking red and TV won't power on. Tried unplugging for a little while but didn't help.


kindly count the blinking led to diagnose where the fault came from..

also try the initial check....open the back cover and inspect the power supply board for any bulged capacitors inside..

I put a new lamp in my hitachi 50v720 tv. The light keeps blinking and the power will not come on


If it was blinking like it was, it's probably either a bad lamp or a faulty install. Try re-installing the housing of the lamp in the T.V. if you're sure you didn't over tighten or under tighten the screws on the lamp. These are all simple things to check before you send back the potentially bad lamp.

Recently there was a storm in my area. Satellite quit working then TV went out. TV is on a surge protector and nothing else quit working but tv. The power light blinks and nothing can be done to make TV...


Usually the blinking indicates a power section problem. That could have been from a power surge. Thats a shop job to fix. Since its out of warrenty you need to get an estimate first. Repair costs can be more than a new tv. Last one I saw was $450ish. If you have any local tv repair shops talk to them , then talk to sharp and get contact info for the repair depot and talk to them. Get estimates from all, then compare that to a new tv cost and you will know which way is best for you to go.

Unless you spent almost as much on the surge supressor as the tv they are only actually meant to protect the wiring in the house. The do not react fast enough to actually stop a power surge. They just cut off a short circuit problem so the house wiring doesn't overheat and burn the house down.

KDF-50a12U Powers off then standby light blinks 3 times


Please recheck Lamp Cover and make sure it is fixed in its space securely as 3 times red blink shows lamp cover error.
There is small safety switch in TV cabinet under lamp cover that has to be pushed by lamp cover if it is fixed in its position properly. That switch is not being pressed by lamp cover and causing this error.
Thanks.

TV turned off by itself and now blinks red led 6 times


6 blinks means a low B error. Which is no DD 6volt output on G1 board . This will cause no picture and no sound. To fix this yourself you would need the manual to get the correct sequence to test and proper part to order. You can get a service manual for 10.99 at the following link and they will ask if you'd like it emailed to you after purchase. Here is the link,
