I own a Mitsubishi WD 57734 DLP (2yrs and 3months old)… A few months ago every once in a while over a three month period the TV would stop working and the RED lamp light on the front of the TV would light up. Restarting the TV would appear to reset things and no issues for weeks. I did see after entering the Serv code recently that the TV has 9,800 hours on the bulb and the bulb had been getting dim over the past few months. I ordered a new bulb and replaced it a few days ago – all went well. All has been working fine – TV is bright and crystal clear again but the shutting off and red indicator had come on again a few times untill today. This morning the TV will only stay on a few minutes and the red lamp indicator comes on and the set shuts down. I do see some posts on reset procedures and reset buttons but did not see my specific model of TV on the forum with this issue so I wanted to ask for advice before I spend a “C” note on a service charge. The last time I had the “Authorozed” service rep come out for a prior Mitsu TV he said I needed an entire board replaced which would have cost over $800. I found another technician who replaced a small transistor on the board for about $250 and I was back in business. Anyway – I welcome troubleshooting advice.
