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.

I have a 56 inch tohiba DLP (56 HM 195). Replaced the bulb for the second time this year. last time only lasted 3 months. TV is tough to turn on. When I get it to turn on, and then shut it down, the yellow light blinks constantly for 5-7 mintues. Then it shuts down completely. Is the set overheating? There is nothing in the manual that speaks to this issue. thank you

It is an error code. Count the flashes and then re-post asking what the amount of flashes means and how to repair it. Make sure you post make and model of TV.

SOURCE: No Picture on Toshiba 42RV530U
I had a similar problem to this yesterday. Tv is same Toshiba model as you mentioned about 4 months old. In my case, after the TV working perfectly following installation, the standby LED on the front (the one that is red on standby and green when on) went to a flashing orange (after switching on from standby) and the picture disappeared although the sound remained OK. I was unable to get any response from the setup or menu on the remote, otherwise I would have tried resetting the TV. Regardless of how much switching off/on (including disconnecting the powerlead and leaving for few minutes), disconnecting all peripherals, etc., nothing helped. I looked up Toshiba's web site and under support they basically suggest switching off the TV and restarting using the onset buttons (not the remote) and pressing the menu button (again the one on the set (not the remote) and if you could get the menu box to appear then reset to default settings. I tried this but the results were the same. I therefore thought the TV was defective. However, after much frustration I did the following (I think): 1) Disconnect everything from the TV 2) Powered up from the mains switch whilst keeping BOTH the startup and menu buttons on the side of the TV pressed down. The result in my case was that the standby led and one of the two beside it flashed green simultaneously. However, when the buttons were released, the TV started up the same (flashing LED orange and sound no picture). 3) Pretty well defeated at this point, after doing the procedure at (2) several times with the same results, I somehow thought of pressing the standby button on the remote either whilst the two buttons on the set were depressed or just after they were released. I am afraid I cannot remember which and cannot replicate the problem as I don't know what caused it in the first place. 4) The TV then started normally ( no reception as I had not aerial connected, etc.,) but I was able to gain access to the screen menu/setup buttons via the remote which were in French rather than English. However, after reconnecting everyrthing the TV has worked fine (obviously after resetting the language via the menu). I am sorry I cannot be more precise but I hope this might be of help to someone with a similar problem.
