Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

You must remove the front bezel and frame holder to replace the screen. You will usually see the screws holding the from from the rear of the unit. Once you get the frame off, take note of the way the old screen is installed. There is usually a label on one side near the bottom; the new screens must be installed with the label in the same location. The lenticular goes on the outside (facing the viewer) and the fresnel goes on the inside facing the mirror. You will be able to recognize the fresnel, it has a series of concentric circles that are raised on the sirface of the plastic Be sure to rate this solution.Thanks!

If the power light comes on (green) for a few seconds and goes off:

MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD "device"(input) and "menu" buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC's is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and two blinks--this is the most common and easiest to fix.

I think you would be lucky to be able to sell it for that amount. Due to the shear size, weight and bulkiness of the tv, it is likely to sell closer to around $250 - $300. I believe the target group that would have interest is likely very small.

That's just my opinion based on what I am able to sell TVs for in my area.

look for a button on the remote most probably labeled " CC " or go into the menu in the audio or setup section and you should find the closed caption settings.

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 keyboard2.gif 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 keyboard2.gif 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.

when the light constanly flashes, you have a bad digital module, in most cases you can remove the module and replace all of the 1000 microfarad at 16 volt capacitors in it, some have 4, some have 7 capacitors. that usually doea it, but you probably need a repairman.
