Mainitpa2,

The voltage and current rating for the fuse should be marked on the circuit board directly below it or very near to it. The majority of fuses in TVs these days are GMA type. If your unit blew a fuse chances are that a new one will also blow at turn on if no troubleshooting was done to find a short. It will not harm the unit to try a new, correctly sized fuse, but don't be surprised if it blows immediately. I have a tip at http://www.fixya.com/support/r6396176-projection_tv_troubleshooting which will help you with the troubleshooting process.

Thanks for using FixYa and for a great rating.

Mitsubishi tv model wt-42311, error code 2-2. what can i do?


2,2 IS short protection and 95% chance it means one of the two pico fuses that protect the convergence IC chips are bad.

This model uses two of the chips: STK-392-110 and you would have to pull the light box out to replace them safely (total parts cost will be under 30 dollars).

It involves getting at the chips and the fuses and replacing them: how much skill do you have?

Mits are bad about power supply capacitors failing. It can be fixed fairly cheaply, but requires some skill at disassembly of the tv and unsoldering/soldering.

Mitsubishi model # wt-4609 .. won't come on... error code blinks two times pauses then two more


This is error code for short protection--95% of the time in this model it means one of the soldered in fuses that protect the convergence circuit is blown.

Both convergence chips and the blown fuse or fuses need to be located and replaced----if you give me the full correct model number I will tell you which parts it uses.

Some people are able to do this repair themselves--depending on model number you would begin by unplugging the set and testing the fuses for the convergence circuit--if either or both are bad the chips for the convergence circuit got them--just changing the fuse will do no good--and can do more harm.

Let me know model number ---wt- and 5 numbers usually

Mitsubishi WT-42311 DLP Bulb Replacement


Your access should be a a panel near the back or side. You will see that it is somewhat easily removed and should have maybe one or two screws. You will see the casing to the lamp. Go ahead and remove it. Now unscrew the old bulb and replace it with a new one. There is not a lot of screws holding it together. It's a fairly easy process once you find the lamp. You should see the lamp once the panel is removed.

Most units give a error code "22" short protect circuit. If so check:

Q5A00
C557
and or the
convergence IC's (STK392-110) had failed and caused a diode (D522) to short
out.
If Q5A00 check bad there are other parts that have to be checked or
replaced.
