Question about Mitsubishi WT-42313 42" Rear Projection HDTV-Ready Television
I have a problem with my TV not powering on. It clicks and lights green on indicator but then clicks off and stays black on screen. It won't power up at all.
Did you get yours fixed?
I found the schematic (downloadable PDF) for $7.99 at http://www.completeservicemanuals.com. Cheapest I found and highly recommended.
The blown fuse was due to a fried convergence IC. There are two of these on the high voltage board; they should be replaced together as a matched set. The bad one had gotten so hot I only had to unsolder three pins -- the rest were already loose!
I found the ICs at http://www.electronic-repair-kits.com, also highly recommended. The correct part for the WT-42313 is STK394-250. Make sure you order a pair and they will send you a matched set.
My set is now operating; I just need to clean the optics and do a convergence alignment.

Mine was a power converter/supply issue. I took it in and 300$ later it was as good as new.
