Cost to repair....over $900, I bought a new plasma set...got to tell ya I am disapponted in this $3000 paperweight.

Listen: you need to wait for the set to first shut off! then push on the TV(not the remote) Input and Menu both at the same time for 5 seconds and then release---the power light will then blink---this model has this feature--
Unfortunately you will need an experienced TV tech. This unit will need 2 ICs STK392-110 for 1 has shorted and caused damage to the 2nd as a result blowing 1 or 2 pico fuses in the power supply. It is an involved job and may be somewhat costly depending on the pricing in your area. Hope this helps
The first thing to do is to try to determine why the set is not turning on. It is equipped with a self diagnostic feature. On the front of the set push the MENU and DEVICE button at the same time and hold until the LED starts flashing a two sequence code. That will narrow things down for us.
The remote is not the problem. The switch for volume up on the control panel has become leaky. Very common problem for this generation Mitsubishi. If you don't mind not having the control panel working you can disconnect it and the set will work just fine with the remote. To disconnect the control panel pull the speaker grill, it just snaps off, and remove the front access panel. Once that is done you'll see a cable going to the switches just disconnect it.
Press in together the menu button and the Device/input button on the set and hold them both in together for 5 seconds and see if the led will blink a two digit error code, then respond to this same post and let me know if it gave a error code and what the two digits were.
