I replaced the power board capacitors, and the DM capacitors on my Mitsubishi WD62725 the tv then worked for about 10 minutes then it powered off and the green blinking light came back on. I only hear the fan on top of the boards running. Is there a fan by the filter that should be running? could this be the reason for the green blinking light?
Ther is a Thermal Switch attached to the back of the light engine labled "JC" on the connector. Sometimes they go bad so you might want to check it.
