Re: Won't turn on

The clicking you here is the mosfet trying to turn on power on the the oscillator then power to the tranformer. The thing with red wire come from the top to a anode splitter. The question is where the power stops. You know it is going to the mosefets but is the trasformer powering the tubs. Email me for anymore questions

Tv turns on and back off

Most of these sets have a self check----if Green power light comes on for a few seconds and goes off on the front of the set press and hold both the menu and input (source) buttons at same time for at least 5 seconds and release both.

Power light will blink a two digit error code like 2 blinks, 2 blinks a pause and repeat it for a total of 5 times.

Let me know if you get a error code and what it is.

Unplugging power from the set clears the error code so if that has been done you will have to try to turn set on, let it fail and then do the self check again.

hi there,

Check for bad solder on convergence module. May have bad stk's. Do not neglect looking for bad solder on dsignal and defl boards. Mitsubishi is very prone to bad solder.

Replace bulb in lg dlp projection tv and tv won't come on

Presuming bulb was installed correctly it could be the ballast that powers it.

If possible try to look from outside where lamp is to see if it even fires up for a few seconds.

My mitsubishi 55" will not turn on... when I press


The most common failure for this model is the deflection board assembly or commonly known as a Large Signal board. The unit is going into shutdown, mode because no high voltage. Unless you are strongly electronically inclined I suggest you try to replace the deflection board.

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast. But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is xl-2100 you can find it here: a blessed one!

TV will not turn on

There are a few reasons that this could be happening first one is maybe the lamp died on you, Afraid there is no way to test this other than replacing the lamp. The second problem may be 5 capacitors on the power supply that hold the 12 volt line low and do not allow the light engine to start properly.
First thing you have to do is listen to how it trys to start, It should sound like this, first when you hit the power switch there may be a click then within five seconds the fans then a few seconds more you may here a sparking noise, if all this is happening then you most likely just have a bad lamp

No picture, hear sound, television will shut off after a few seconds.

Lamp life is only a few thousand hours. Hopefully its only the lamp that made to noise. Don't turn on again until lamp is replaced.
