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..

My Sony TV Model # KP-51WS510 flushing 4 red light or blinking 4 red light again and again, once I turn on the TV power. No picture on the screen and you will hear that it will shut off but the 4 blinking...


Usually a flashing power light on a rear projection TV means a bad bulb, try replacing the bulb. Also try unplugging it for 10-15 minutes, then come back and plug it in and try again. Also if its been a long time since its been serviced it could be dust buildup causing overheating, do you hear the cooling fan running? It could also be a failed cooling fan. Generally the first thing i do with projection TV's is clean them, clean all the vents, pull the bulb out, clean out the cooling fan and bulb housing, and then try a new bulb. If that doesn't fix it then its a bigger internal problem and there is no quick fix but have it serviced.

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.

Hi,
Symptom shows Lamp is weak in result and causing restart of TV again and again. Your TV requires new lamp as per following part number...
A1085447A* LAMP BLOCK ASSY XL-2200U
It is available in Sony Accessories Store for $200 and replacement procedure is written in instruction manual of TV.

Always buy Sony original lamp for TV and avoid aftermarket / cheap lamp for TV safety.

Kia optima low beams


First verify that the switch is energizing the relay in both positions by turning the low beams on and then pulling up the relay--does it click? If not, replace the switch. If yes, next check for power on the red wire as it comes out of the column. Switch on, no power--replace the switch. If power, check for power at the head-low fuse in the engine compartment fuse box. No power--find break in wire. If power, check for power on the yellow/red wire as it comes out of the fuse box. No power--repair fuse box. Power--check for power at lamps--same wire. No power--repair yellow/red wire.

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,
