    When turning on the TV the green light lights up as if the TV is coming on and then it clicks back off within a few seconds. This is with the remote as well as manual.

    WT-42313 turns on (green light on) with either remote or tv panel button THEN immediately shuts off a few seconds later. It won't stay on.



    Wondering since the previous two posts are within months of my problem occurring if we're not all experiencing a defective part or problem that's just being noticed now? ie: happens after 'x many hours of use?' And wouldn't you know it would happen just when the Olympics are having swimming finals tonight!

It could be coolant leaked from the CRTs, or a failed fuse due to the conv ICs shorting out or going open, depriving the turnon circuitry of its proper voltages.

These are the usuals. Since Mit has very elaborate protection circuits, it could be anything. More troubleshooting needs to happen before we'll know more.

I do a phone coaching service if you want to check that out.

Mitsubishi DPL TV model wd73c8, serial 100759. The tv will not turn on & has a solid red light in status.


Try to turn it on manually by the power switch - not by using the remote control. Try to unplug it for an hour or more to discharge the power system, then try again.

Replace both of your STK ICs set should come back on then, they are big black ICs will have part number on them.Call Mats for parts 1-800-628-1118. STK392-570 maybe what your TV uses.

there are 2 fuses -24v and 24 v normally would go out because
covergence ics failled . That would be a shutting down problem cased by missing those voltages.so you would need to replace those 5A (small green fuses) , you would need some kind of soldering and unsolderin skill) and the ics are stk392 570.two also. open the set from the fron ,taking speaker grill off and then the wood board behing (4-6 screws) you the the board in the center big metal heatsink. you would need to work from the back to repace those puppies.hdtvman
