ONLY 1 of 2 things can cause this problem----
First thing to do is
remove front speaker grill--it should pull out and is secured 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 the set---remove the inspection plate and follow the wires to the
right--you can unplug both plugs(most have two and they are marked with
letters and different sizes so you cannot get them wrong)
The
idea here is to remove the front with its reset button etc
from the circuit---You will still be able to try to turn the set on
with the remote---
These sets have a Receiver that is called a DM board--(large metal box to the
left as you look from the back) and if the power goes out the green
light will blink for about 70 seconds and then go out---it is the
Receiver booting up. It is called the DM board.
If disconnecting the keyboard allows the
set to turn on--you have a bad reset switch and two choices---either
operate the set only with the remote or to remove the front screen and
get at the reset switch (it is tiny) and remove and/or replace it.
If
disconnecting the keyboard does not restore the set to operation---the
receiver is bad---there are 4 or more caps and some pico fuses that can
fail in that unit---Mitsubishi no longer sells or repairs these--if it
is bad and not the caps there is a company you can send the unit to and
have it repaired--if you need to know their name let me know---
You can
call them and get a quote for repairing the receiver. There are also sites on the internet selling a kit for this repair.

Start by checking the lamp, there's no sure fire way to tell if its the lamp or not.Remove the lamp housing door off the back right side of the tv (if you are looking at the back of the tv, it has one black screw holding it in place. Look inside and you'll see the black and silver metal housing. Then loosen the gold screws on each side of the lamp housing. You'll know you're looking at the right thing because there is a black handle that lets you pull the housing straight out (after loosening the screws, the screws wont come completely out). Take into account the amount of time it has been since you replaced the lamp, 3-4 years seems to be about average. You won't really be able to tell if the lamp is burned out or not by looking at it. Sometimes there is a break in the glass tube inside the bowl, sometimes its a white powder in the small bulb at the bottom of the glass tube. Either way, use the stickers on the housing to get your lamp number and order a bulb. Rivervalleyelectronics.net is a great place to look. I use them all the time. Any osram or philips bulb off ebay will work fine too. Email me directly if you need further assistance. [email protected] Good Luck
SOURCE: please help with tv! green blinking light wont stop and tv wont 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.
please post your error code
SOURCE: TV wont come on
One of the tubes are gone. You need to replace one. The easiest way is to disconnect the board from the tube. power it on and if the correct tube is disconnected, the TV will turn stay on. Research the problem a bit. This is a common problem
