Question about Projection Televisions
The TV is on protect mode.
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.
If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.
1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.
2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.
If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.
Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.

It is the balister not the lamp. Very common problem that Panasonic will not address. Costs over $600 to repair. file a complaint with consumer affairs please.

I can almost guarantee that the circuit board(s) have bad capacitors on them. I repaired one last week that had 20 bad capacitors on 4 boards.
Fixed one the week before with 15 bad caps on two boards.
A repair shop may be able to replace the boards, but it may be expensive.
- I hope my diagnosis is wrong-

THIS IS MY STANDARD ANSWER TO THIS QUESTION==SOMETIMES PEOPLE DO NOT
TRY THE EASY POSSIBLE REASON--IF YOU HAVE ANY QUESTIONS LET ME
ONLY 1 of 2 things can cause this problem----
First thing to do is remove front speaker grill--it should pull out and is secured with plastic pegs--behind it you will find an inspection plate---
Notice the one or two pairs of wires coming from the front keyboard of the set---remove the inspection plate and follow the wires to the right--you can unplug both plugs(most have two and they are marked with letters and different sizes so you cannot get them wrong)
The idea here is to remove the front keyboard with its reset button etc from the circuit---You will still be able to try to turn the set on with the remote---
These sets have a Receiver that is called a DM board--(large metal box to the left as you look from the back) and if the power goes out the green light will blink for about 70 seconds and then go out---it is the Receiver booting up. It is called the DM board.
If disconnecting the keyboard allows the set to turn on--you have a bad reset switch and two choices---either operate the set only with the remote or to remove the front screen and get at the reset switch (it is tiny) and remove and/or replace it.
If disconnecting the keyboard does not restore the set to operation---the receiver is bad---there are 4 or more caps and some pico fuses that can fail in that unit---Mitsubishi no longer sells or repairs these--if it is bad and not the caps there is a company you can send the unit to and have it repaired--if you need to know their name let me know---
You can call them and get a quote for repairing the receiver.

Did you ever get a answer to this question? I have a hitachi 50vs810 with the same problem. I found the same sensor "tokin ohd3-90m."
I ohmed across mine and it shows open. I then held my lighter under it and it stayed open. I suspect this part is bad so I tried jumping it out. No change. Still have the same blinking temp light.
So... in the end I don't know if I tested it right or not either. Good luck and let me know if you learned anything that can help me out.
