Faded pictures it is caused by leaky or short capacitor it could also be power supply problem causing the optic engine and light not to work correctly, or you could have a bad DM board, or a bad light engine sounds like a bad DM board find six of the fourteen known-problem caps to be visibly bulging -- both 3300s and two of the four 1000s on the PWR PWB plus two of the four 1000s on the FMT PWB (see photos below). Ironically of the four 1000s on the DM PWB, which I have heard are the most common to go bad, were bulging and I considered skipping these as the DM it is the toughest board to extricate from the chassis, however I figured I had come this far and I would just as soon replace all twelve 1000 uFs as the parts cost $0.23 and I really never want to have to do this again.

If I had to bet, the two 10V 3300uF caps on POWER board, which were actually leaking black goo, are the actual culprits, but with four of the 1000 uFs also bulging it is probable only a matter of time until they failed as well.

Here is the POWER PWB with the known-problem caps (C9A37, C9A38, C9A51, C9A52, C9A61 and C9A62) highlighted:

here's the FMT PWB with the known-problem caps (C8F19, C8F21, C8F22 and C8F27) highlighted:

and the DM PWB with the known-problem caps (C81A2, C81A3, C81B3 and C81B4) highlighted:

Here are close-ups of the bulging caps (C9A37, C9A38, C9A52 and C9A62) on the POWER PWB:

Air flow blockage


Take care of it NOW. We ignored the error (knowing we're under a service plan so we'd get to it eventually). Then last week the TV just cut out and we got no picture and the red lamp light came on. Service guy came out today and replaced the lamp and it didn't work and then called Mitsubishi. They said it is probably a very common capacitor problem on the power supply board. If you open the back and take a look you are likely to see bulging caps. Parts C9A37 and C9A38. The caps are cheap if you can find them, but the parts are really hard to find right now so Best Buy is actually replacing these for people under service plans rather than fixing them. The message you are getting is a sign that the caps are getting too hot and need to shut down to cool off... It will eventually ruin your lamp if you let it go on.

Good luck! BTW, our guy said the repair will run you about $200 if you can't do it yourself, but someone else on this board with guru status recommends a kit that comes with a CD and a manual that will help you fix this. They even give a web address to order it. If we weren't under a service plan I would be going this route...
