    I took off the back and the capacitors on the power supply board look the same.

First of all try all inputs!

If its doing this on all inputs "everything" and you have no lcd but sound, the issue could be with one of the back light inverters not firing, it also can be caused by a bad power supply. so check the following

1. check all inputs
2. try unplugging the tv waiting a few min's then plugging it back into the wall.

If both those do not help it will need repair, now I do not recommend Mike if you not tech savvy to dig into this tv, I would prefer you take it in to get it worked on.

Let me know

otherwise please od click the accept button for my efforts.

I have a Whirlpool (2004?), and when I release the reset button, the pilot goes out...as long as I'm holding the reset button down, the pilot stays lit. Even after two minutes, when I think it'll stay lit...


Almost always it is the thermal coupling, change that and try again...They're not too expensive, but you do need to get the correct one...

Alternatively, hook up a bicycle and have the teenagers generate the heat...... << Good luck selling that one. Tell them ALL of the teenagers do it.....

No sound at all on Mitsubishi LT-52151. Fixed before by unplugging, waiting 30 seconds, plugging back in. Was occurring more and more often to the point of having to do this every time I would turn it on....


Just fixed this on my TV today! (after 2 months of the sound intermittently failing to turn on and failing completely yesterday) Go to Mitsubishi-tv.com. Go to support. Enter your model number. You will be directed to the documentation for your model which will include a zip file for a firmware update and a PDF file with instructions for installing the update. This fixed my sound.
