you may have a bad colorwheel or its possible the flyback is going out on the tv itself.either way you will eventually lose the whole picture

um . that model doesn't have a reset button . but if no lights on front of the set even blink when you press the power button on the front or on the remote .then suspect front panel buttons ,with that model.

ONLY1 of 2 things can cause this problem----
First thing to do is remove front speaker grill--it should pull out and issecured with plastic pegs--behind it you will find an inspection plate---
Notice the one or two pairs of wires coming from the front keyboard of theset---remove the inspection plate and follow the wires to the right--you canunplug both plugs(most have two and they are marked with letters and differents so you cannot get them wrong)
The idea here is to remove the front keyboard with its reset button etc fromthe circuit---You will still be able to try to turn the set on with theremote---
These sets have a Receiver that is called a DM board--(large metal box to theleft as you look from the back) and if the power goes out the green light willblink for about 70 seconds and then go out---it is the Receiver booting up. Itis called the DM board.
If disconnecting the keyboard allows the set to turn on--you have a bad resetswitch and two choices---either operate the set only with the remote or toremove the front screen and get at the reset switch (it is tiny) and removeand/or replace it.
If disconnecting the keyboard does not restore the set to operation---thereceiver is bad---there are 4 or more caps and some pico fuses that can fail inthat unit---Mitsubishi no longer sells or repairs these--if it is bad and notthe caps there is a company you can send the unit to and have it repaired--ifyou need to know their name let me know---
You can call them and get a quote for repairing the receiver.
Let me know what more information you need--I am here to help.
