I tried unplugging and waiting a while, but same result. Tried pressing re-set and waiting a few minutes and powering on, but same result. Status light is solid red.
Two thoughts:
First is this is a DLP set and the lamp may have failed
Second is it should have the self check which reads error codes---most of these sets that is the same:
" After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
(then release both)
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected
This is for a earlier Mitsubishi DLP but should be the same as your set as Mitsubishi rarely changes things like this.
If you get the lamp abnormal it is likely your problem.
SOURCE: I fixed the blinking light, but still no picture
Here is the correct and official service manual on the unit. Check all of the diagnostics first, then go into the service menu and validate your settings.
