Question about Mitsubishi WT-42311 42" Rear Projection Television
TV turns itself off after about 45 minutes (green light remains on). I can turn off the TV and turn it back on immediately, however, the TV turns itself back off after a few minutes (possible heat/overheat problem with an electronic component).
The TV turns itself off right after I turn it on. Anyone know what that could be?
I had a similar problem with my Phillips 42 in. LCD HD TV.
Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.
Hope this helps
