Mitsubishi is notorious for power supply problems. you probably at least have some bad caps on the board and also various regulators that are gone this usually due to bad or cold solder connections on the bottom of board. unfortunatlly it can be expensive, if the tv is over 8-10 years old, i would opt for another set. if however it is newer it might be worth it don't spend over 400-500$ for repair
new and used sets are almost half the price
they where 2 years ago. stay away from plasma and anything from phillipsmagnavox
any ? hit me up i am a consumer electronics

My Mitsubishi TV power light comes for about 12 seconds, without any picture, and turns off.


Try the self check when power light goes off, on front press and hold both the menu and input buttons for at least 5 seconds and let both go.

Power light will blink a two digit error code like 2 blinks,2blinks, pause and repeat it several times.

What error code do you find?

IF model number posted is correct and green power light comes on for a few seconds and then goes off:
On front of set press and hold both the Menu and Input (device) buttons at the same time for at least five seconds and release both buttons.

Power light will then blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.

Let me know what error code is found and I will tell you what it means.

I turn the tv. on , the green light comes on then


When you turn it on and it shuts off---ON THE FRONT OF THE SET PRESS AND HOLD BOTH THE MENU AND INPUT(DEVICE) BUTTONS TOGETHER FOR AT LEAST 5 SECONDS AND RELEASE BOTH BUTTONS.

Power light should blink a two digit error code---for example: 2 blinks, a pause and 2 blinks--This is the most common error code.


Let me know what error code you get and I will tell you what it means and if 2-2 what the problem is.

My 65 inch projection TV turns off within a few seconds when I turn it on. Why? No pictures or sound.


If power light does come on and a few seconds later it goes off---do the self check that the WS65909 MITSUBISHI should have:

On the front of the set press and hold both the MENU and INPUT(OR DEVICE) BOTH FOR 5 SECONDS AND THEN RELEASE BOTH BUTTONS.

Power light should blink a two digit code--error code---for example: 2 blinks, a pause and 2 blinks.

Let me know what code you get----it will repeat it several times---and I will tell you what it means.

TV turns on, then turns itself off about 2 seconds later.


set has a self diagnostic---after set does shut down press and hold MENU AND DEVICE(INPUT) buttons on front of set for 5 seconds----if 2 blinks, a pause and 2 more blinks: this is short protection error code---The set does use 2 Stk394-250 and each is protected by a pico fuse in the power supply---if either fuse is blown the set will shut down(it detects no voltage or missing voltage;) It is not uncommon for a shorted IC to cause this problem; if you locate the STK's look carefully at the resistors around them---if any are discolored or burnt---you have found your problem.

Mitsubishi VS-60705, Turns on/Turns off.


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 Normal 0 false false false MicrosoftInternetExplorer4
