Problem with Mitsubishi 60" TV (Model No.: VS-60705)

[midaiz1221b]

As mentioned in the subject line, I have a Mitsubishi 60" TV (Model No.: VS-60705) that recently started shutting down upon turning it on.

I would turn on the power (both by either remote control or on the set itsself) and i can hear the TV turn on, but 85% of the time, it will immediately turn off again after only a few seconds. Occasionally, the TV will stay on a few seconds longer.

Sometimes, it stays on long enough to render a picture. If/when this happens, the image is distorted. Sometimes, the images 'adjusts itsself' and looks fine. But, most of the time, the TV shuts off again.

What could the problem be? And how do I go about fixing it?

I've checked the power cable. It seems fine. Could the TV be overheating? Is it true that if I leave it on for 6-8 hours straight, that this kind of problem can occur?

Any help on the subject would be much appreciated.

you might check for poor solder connections on the vertical output IC. It may also be some bad capacitors in the power circuits.

Solder up the convergence ics to start.

press menu and input at the same time when set won't power up. Read the error code displayed by led.

I am experiencing the same issue. My TV will only power on for less than a second and then immediately shut off. Despite this TV being on a surge suppressor (for both the power and the coa), this trouble began immediately followig an electrical storm. I did open the back and found a fuse that I am going to have checked (though it looks okay). Service call is $115. What did you end up finding out?

I have just had our 1998 50" Mitsubishi rear projection TV looked at by a serviceman and after diagnostic checks on all tubes he's saying we need to replace the "power deflector board?" Can anyone let me know just what that is and how much you might estimate a cost for?? After finally finding someone to come to home and check out it cost $100 just for the look-see and estimate.

Same problem as everyone else. right after start up it shuts down. i get a blink code of 2 - 4. Repair man seemed just as clueless as me. there is only one Mitsubishi repairman in the area.

any suggestions, i can solder.

Code 2-4 is the +24 volts vertical deflection failure. Could be bad convergence IC's or the vertical IC puked.
