have you checked the lamp? with those models they will power up and if the lamp is bad you can hear audio until the tv shuts off. the lamp is located in the front behind the speaker grill assembly. if the "status" light is blinking then you are having a fan failure if the "lamp" light is on then check the lamp like i listed above.

does it give you the "airflow" message?
if so it needs a new thermal sensor by the lamp, known issue defective sensor..

if not, suspect bad capacitors
there are many bad caps across 3 board , all part of the chassis.
a repair center will ship the chassis into mits for rebuild, about 400 or 500 total bill

Thermal fuse is the most likely cause

I trashed the set and bought a new one.

Is the LED blinking a 2 digit code? Let me know mitsubishi will blink a repeating diagnostic code when theset goes into shutdown. Which is what your set is doing. let me know if you can distinquish a blink code from the LED.

resolder the horizontal driver transformer and all of the coils that start with "L77xx" on the left side of the sweep board, there is also a jumper staple just above L7711 that must be soldered it does not have a designation number but you`ll see the solder is bad on one end, very common issue with your model.

I Can Assure You That This Problem Is Associated With 2 Capicators On The Power Supply Board.
