shaun

Now the tv u turn on?Ur tv now,have no power to the tv at all or the tv have a red or green LED power light indication is flashing only?Yes,than the tv power supply board is the causes and the problems.That the tv board where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Hi, This could be an internal fuse in the tv itself, worth a check if you are confident yourself, make sure you replace it with the exact same type and rating, if it blows then there will be a pretty bad fault somewhere on one of the panels, most likely the power supply.

Please! if you are going to attempt anything yourself be careful, always unplug the TV first before attempting anything and be aware that power can still be held within the TV even when off.

If you are at all unsure please consult your local TV technician.

have a 55 inch Mitsubishi TV.. the green power light keeps blinking.. is there anything I can do myself?.. or I have to have someone to get it fix?

possible bad light engine

The power light is an error code that tells me exactly what is wrong with the TV. Count how many times the POWER led flashes per second? (Dont worry about the OPC led)

1x per second (constant steady blink) = bad inverters/lamps
2x per second = bad power supply
3x per second = bad main board

If its 1x per second, try doing the factory initialization to get the TV back on to confirm a bad lamp/inverter.

Try doing the Factory Initialization (WARNING: THIS GIVES YOU ACCESS TO THE SERVICE MENU. DO NOT ADJUST ANYTHING IN THE SERVICE MENU OTHER THAN WHAT I PROVIDE YOU IN THESE INSTRUCTIONS. IF YOU DECIDED TO ADJUST ANYTHING OTHER THAN WHAT I PROVIDE YOU IN THESE INSTRUCTIONS, I WILL NOT BE RESPONSIBLE IF ANYTHING WRONG HAPPENS TO YOUR TV.)

1. unplug tv
2. press and hold at the same time “Vol –“ and “input” button on the TV set.
3. while holding those buttons, plug the tv back in
4. the tv should turn on by itself, keep holding the buttons until the letter “K” appears. Then let go.

Once the TV turns on, take a look at the screen. Does it flicker then shut off? Or do you hear a buzzing noise from the right edge of the TV? If so, then you have bad inverters or lamps. Once youre done, unplug the tv to get it out of the service menu.

If it is 2x per second or 3x per second, then those boards are just bad and they need to be replaced. There isnt anything you can do right now to fix it.

It sounds like you've lost the primary winding of your High-voltage transformer or the regulator....accordianman

If your model # is 32V420T, your TV probably has a bad
transformer = part # 271996............if not,please provide......T.
