Question about Televison & Video
Got the tv from a friend from college right before black friday and it worked great, but about 2 weeks ago the lamp went. Nbd; get the new lamp, slide it in, easy peasy. Now however when i turn on the tv it tries to act normal, screen goes bzrt and i can hear a circuit or something click and the fans kick in but theres no picture (unsure about sound). It will cycle for about 2-3mins thru trying to startup and turning off, power light blue and alone for ~10secs and then solid blue pwr light and the lamp light blinks yellow every 1sec. Sometimes between startups the blue light will go out and the yellow quickly blinks ***-***-*-*. When the tv gives up at last the lamp light is solid yellow and the standby(i think, this lights unlabeled) flashes red. I did manage to get the tv to speak to me, trying to explain thats there's still a problem with the lamp as it begged me to call Toshiba support. Now i have the back panel removed, most of the wires double-checked and a majority of the dust removed, but what should my next move be?
Check the circuit boards to see if any have failed. They are small cylindrical objects. If the tops of any of these are bulged instead of flat then they are bad and board will have to be replaced. Hope this helps.

There are three fans the one that usually fails is located on top of the optical block and cannot be reached by the owner unless you take the set apart yourself. What is happening is that one of the fans are not spinning fast enough or has stopped altogether. The best solution is to replace all three fans cleaning may not be enough to get a slow fan up to speed, and the tech should blow out the dust in the duct work. This is what the tech coming out will (or should) be doing. Also some fans will have an intermittent startup, and cause this intermittently, so it is a good idea just to replace the fans instead of just cleaning them.

SOURCE: TV doesn't turn on
You really should give make & model number when posting, it helps us immensely, your lamp and possibly the ballast is bad, start with a new lamp first, odds are very good that it will fix your problem, can`t help more without manufacturer and model number, good luck, ps, order the original lamp, generics are junk and a waste of your money.

SOURCE: I have a Mitsubishi WD-62525.
the status light blinking red means a fan (the unit hs 4 of them) has failed. you need to determine which one. use the self diagnostic function:
Error Code Operational Check
Note: The TV must be in “Shut Down” and not manually switched Off, to perform the Error Code Operational
Check. When the TV is switched Off, the code automatically resets to “12” No Error.
Press the front panel “DEVICE” and “MENU” buttons at the same time, and hold for 5 seconds to
activate the Error Code Operational Check. The LED will then flash denoting a two digit Code.
Note: The front panel buttons must be used, NOT those on the Remote Control.
• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2 second.
• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
Example: If the Error Code is “32”, the LED will flash three times, pause, and then flash two times.
• The Error Code is repeated a total of 5 times.
and read the code.
35= Chassis Fan failure
36 =Exhaust (Back Cover) or Lamp Ballast Fan failure
37= Engine (DMD or Lamp) Fan failure

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.

unfortunately I don't have any solutions for you. I have just started to have the same problem and have only replaced the lamp. i was going to move on to the ballast but wouldn't want to if it going to be a waste of time. Did you ever find any way to resolve the prolem?
