My Toshiba Rear projection TV Has A blinking power light

Power light blinking TV Won't turn on

Posted by on

  • james3332 Mar 04, 2009

    My TV just stopped turning on. The power light blinks but it doesn't go on. When I unplug the set and plug it in again, I get a couple of clicks, then the red light starts blinking again. This TV is about 10 years old.


    Is this a power supply problem? If so, about how much would it cost to repair it? Any other potential problems besides the power supply? Does it make sense to have a TV repair guy come out to the house and look at this or will the cost of repair, no matter what it is, probably be the same or not much less than getting a new TV?

The power supply is in protect mode. There is most likely a short on one of the boards, or the high voltage generator, or a scan amplifier, or the power supply itself has a failure. Without troubleshooting the set it is impossible to know.

Thats the error code for the convergence. You can get the PT53WX53 Convergence repair kit at the following link. www.tvrepairworld.com

You likely have bad convergence output IC's that have caused one of the supply fuses to blow. This repair will have to be performed by a qualified technician. If you were in our area and has us repair this the total cost of the repair would be about $340 if I am correct about the cause of your problem.

SOURCE: sony projection tv no power

I purchased a service manual for $16.99 from ServiceManual.net. I downloaded the manual. Read it and you have to make note of how many times the power LED blinks red. My 55" Wega was blinking 6 times then pause then repeat.
The manual indicated it was a "Low B error, No "DD 6V" output ( G1 Board) No picture/No Sound.
The manual gave me instuctions on how to remove the G1 Board. I took it out and clean off the dust reseated the G1 Board, still the same problem. I order an new G1 Board, part# A-1060-177-A from the "Partstore.com" for $186.25
Problem is fixed and I save $350 on service call.

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.

65" mitsubishi rear projection tv won't turn


IF model number posted is correct and green power light comes on for a few seconds and then goes off:
On front of set press and hold both the Menu and Input (device) buttons at the same time for at least five seconds and release both buttons.

Power light will then blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.

Let me know what error code is found and I will tell you what it means.
