Any idea on whats causing this thing to allow me to cut it on, but only for about 2 seconds, then it shuts off, never see a pic or sound??? Need service manual, if availiable. Thanks

i replaced the 4 capacitors and checked the on board fuses they are good i reseated the dm board several times with and it appears to be seated correctly with no damage to the board or connectors what is next in the troubleshooting area.

I have a Mitsubishi ws-65711 witha DiamondShield on it. It has some fingerprints on it, but more that than is has some areas when it has been scuffed up. It does not appear to be "scratched" or gouged. From the manual I gather this is a fairly particular in how it is cleaned. Does anyone know how it can be cleaned/polished?

Thanks
