Unplug the tv for a while and plug back in.if it doesnot help then check out for bulged or blownout capacitors on the board.if you find any of them faulty just replace it and check.it should most probably solve this problem.

That means that the tV is on protection mode, start unplugging the set for some time first.

    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 on dvd with no receiver box 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 Monitor goes on protection there are only two possible causes.

    1The
    internal circuits are jammed because of electrostatic
    chargesaccumulating on capacitors, or because of a wrong voltage read
    by themain chip on your monitor controller board. this started the
    protectioncircuit.

    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.

    Commonfaults
    that can occurr suddenly are a blown capacitor on power board, a
    convergence IC has blown, or a fault on Digital board.
    check also
    the video cable, if the cableis shorting, or the connector is bad, you
    can get same flashing statebecause of the video cable.

    Check also connectors, try moving the video cable, and if the cable is not built in, then also try a replacement 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.

The TV keeps shutting off, then shortly after turns back on, then shuts off again... Plugging the cord into a different wall outlet doesn't solve the problem. Please help! Thank you


I'm having the same problem. My TV will play for for awhile and then it just dims down for about 1 to 2 minutes then powers up again. The green light stays on doesn't blink at all, and there is no red light that comes on or blinks like when our lamp went out. We replaced the lamp about 6 months ago and it's been working great until this week.

I have the same problem with mine. I can recreate the problem by stopping the small fan on the right side by the inputs. I'm not sure if its a heat problem or not. I already bought a new Sony Bravia but will continue to tinker with this for awhile.

The tv shuts off by itself. I will turn it on..and after awhile, it just turns off by itself, and then after about a minute I can turn it on again and watch tv for awhile, and then it will do it again.


It seems that your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. The faulty component(s) are heating up, tripping the fault control, and shutting down, it cools down again,and will restart, then the process repeats, it will eventually fail fully.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done. It is that sound that gives it away, this is a typical switchmode Power Supply problem.

Toshiba projection tv


Unplug the TV from the outlet for about 30 seconds. This will reset the microprocessor. Re apply AC and power on the TV. If your lucky the set will come on and play. If not, the red light will start blinking again indicating shutdown. There are many reasons for the set to go into shutdown, but one of the most common cause is failure of the convergence output IC`s. If your TV is in shutdown, you will need to find a qualified technician for proper diagnosis and repair.

Hitachi 50ux58b



If you have Hitachi model number 50UX58B, 60UX58B, 50UX58K, 60UX58K, 50SBX78B or 60SBX78B and you have the following symptoms you may want to grab a repair kit from www.TvRepairKits.com. They have put together a kit that includes the parts and instructions to fix these models. This is a fairly common problem with the above model numbers. It is typically caused by a blown capacitor and pico fuse. Again, you can get a kit from the above address. 
Here are the symptoms...

Primary Symptom: No Audio or Video. Power light will come on briefly then shut off.
Other Possible Symptoms : The green LEDs on the circuit board light up for a few seconds then turn off.

Hope this helps,

Pioneer sd532hd5/kuxc/ca powers down on its own


Could be a few things.First check your sleep timer.Sounds like a fail safe mode that when the tvs left on accidentally it shuts itself down so it wont overheat and die prematurely.The last resort is to remove the circuit board and carefully inspect the solder joints near the power supply with a magnifying glass and a bright light.Then resolder those.
