My RCA 52" HDTV Rear Projection TV Model #MM52110JX1 will not turn on. Neither the remote, nor the front panel switch will turn on the TV. When you press the power button on the remote, the red indicator...

you must check the light indicator if how many times does it blink which tell the main problem or the error code of the tv. either the power supply doesn't work normally or the lamp need replacement.

Hitachi 60UX58B will not turn on

I think there could have been a power surge... ask the repairman if the power supply is blown. :)

TV won't turn on

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.

For example, 3 flashes, then 7 flashes = 37.

Here are the error codes, and the corresponding problem:

12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected

Mitsubishi VS-50607

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source.

Tv will not turn on

The blinking red light is telling you that the set did not start up due to an overvoltage somewhere in the set. Most likely the main power supply has a fault like a bad regulator IC or a component associated with it, or there is a fault in the sweep power supply somewhere. if you have no electronic repair experience, play it safe and call out a tech to assist you with this repair. Good Luck.
