My 2006 WD-65732 has sound but no picture.

My 2006 Mitsubishi WD-65732 65" DLP has sound but no picture. After hearing the sound with no picture for about 1 minute the sound goes out and the Status light turns constant red. The error code I get is 61. Help! Getting sound and no picture has happened to this set before but, by unplugging it for a while and plugging it back in got a picture again but that is not working this time. Also, does anyone know if one can find all the error codes & what they mean posted somewhere on the net?
