These power supplies are complicated to work on. There are some preprietory parts that you would not be able to genericaly puarchase from general electronic parts suppliers.

If you are very strong in knowledge about power supply design, and if you can have the service manuals, have a scope and a DVM, you should have a chance to figure out what the fault is.

Take care that switching power supplies can be dangerous to work on. They employ high current using high voltages on the drive side.

Normally, these power supplies are not designed to be servicable.

When you remove the back of the set. You will fined a couple of caps on the power supply board that are bulged and they need to be replaced, or you can buy a new power supply at www.partstore.com. If you want to just purchase the caps, you can get them at www.mcmelectronics.com

Parts for older Mitsubishi are difficult to find. If you give me the complete model number I can check if the part is available online.

Light is blinking after power failure


If the light is blinking and the TV wont start up, chances are that the power supply got spiked when the power came back on...look for blown components on the power supply board, or buy a new power supply board.

WARNING: be careful, messing inside TV's can KILL! If your not sure what your doing, Pay some one that does!

Picture and sound on my old zenith bigscreen flash on and off.


Sounds like a power problem to me. Possible shorting out inside the tv. If its old I would recommend discarding this tv. The price of repair costs are really high for TV's. You can probably upgrade to a flat panel for what the repair cost would cost you to repair this older tv.

Does it turn off and on as if you were pressing the power button? Or does it happen really fast? If its happening as if you were turning the tv off and then having to wait for it to come on again I would say its the power supply which is probably going to cost you hundreds in a repair shop. However you could possibly find a power supply for it on ebay buy searching for the model number and brand in the search area of ebay. Putting a power supply in a tv isn't really that hard, unless there is something in the way to get it in or out of tv. Usually it just involves unscrewing it from the chassis and unscrewing the hot wires and ground from the supply...then putting the new one in and screwing them back down.
