Question about Mitsubishi WT-42311 42" Rear Projection Television
My Mitsubishi projection TV worked fine, then shut off and when I attempt to turn it on, the light comes on for about 3 seconds and shuts itself off, without sound or picture. I tried pressing the menu and input buttons simultaneously but nothing changed. Please advise...
Same problem, same solution. Small green pico fuse on the power supply board. There is a sticker inside the back cover with the layout of the fuses on the board. Check them all, one of the 5A125V is bad on mine. I have the board out, now I just need to locate a replacement and someone with the skill to solder it in for me. Thanks for the help...hopefully this saves me thousands on a new TV. I bought this TV five years and one month ago to the day. Guess when the extended warranty ran out...a month ago today.

Mine did the exact same thing after I turned it on and turned off too fast. Checked all the fuses with a multimeter and found a bad one. soldered in a new one and works perfect now. $7 fix with a few minutes of my labor. I got lucky that it wasn't something particular that blew the fuse but that is a good place to start
Hope this helps.
