SOURCE: TV is not powering up and red light keeps flashing

I had the same red blinking led problem on my Toshiba Theaterview tv. I resolved by:
- Unplugging the tv.
- Press several times (3 or 4 times) the tv Power button.
- Plug the tv back in and press the Power button once to turn the tv on....tv worked!!!

I've had the problem before and tried unplugging the tv for a couple of days and that had also worked, but I this recent solution seems to be faster.
Good luck!

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

You probably need a new projector bulb. Google up your model and buy the best warranteed one you can find. Buy a "caged assembly" and not just a bare bulb.

Then unplug your tv and get a screwdriver. Follow your model's instructions and just snug down the electrical screws. Do not overtighten them.

Then consult your manual on how to reset the lamp timer so it knows you put a new bulb in and fires up from the first try.

Treat yourself because you've just saved yourself a trip from a repairman!!

Turns on and off then back on then off


Discovered bulb had blown out.
At power on button, red light and green light flashed and no picture was present. I opened side panel after unplugging tv and let the bulb housing cool, then removed the bulb and discovered it had blown. Luckily I had a replacement bulb from the purchase, replaced it and it worked again.

50" philips won't power on. get the 4x red blink led light


i have fixed 3 of this tv, with that exact problem in the last 2 weeks, needs a power supply, you can try to unplug it again, plug it in, hit the power button, as soon as it turns green, unplug it again, after 15 seconds , plug it back in, if power doesnt turn on by itself, turn it on, if it turns red again, emediatily hit power again, may have to hit power a few times in a row, but most of the time you can get it to come on this way, once it is on, it should run ok, until you turn it back off, but not a fix, needs power board

No the DLP units can flash more than 8 times. 9 blinks mean Zero Crossing detector which means diode number D6166 or D6114 is open they are on the A board.Let me know if you need any further info.
