Hi and welcome to FixYa,

Your described problem indicates that the TV is in auto protect mode. Its built-in diagnostics detected a fault and prevents the unit from turning on. This is normally brought about by a power failure/fluctuation. Often culprits are capacitors that has leaked or blistered due to electrical surge.

This page describes the repair procedure. It has also links to step by step images. If I may add, it would be to your advantage to have access to a Service Manual or at the very least, a schematic diagram.

Good luck and thank you for using FixYa.

I have a WS-65907 tv, it wont turn on


Mitsubishi self check: 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.

Turning off when trying to turn tv on..


If power light comes on for a few seconds and then goes off: On the front of the set press and HOLD both the menu and input (device) buttons at the same time for at least five seconds and then release both.

The power light should blink a two digit error code: 2 blinks, a pause and 2 blinks is the most common.

Tell me model number and what error code you find and I will tell you what it means and if possible what needs to be done.

This is a self check feature all WS model numbers had.
