Try first unplugging the TV for 20 or thirty minutes , see if this can reset the unit.

If the TV does not restart, then it means that there is an internal fault, often a pproblem with the power board.

My WD- 73727 dont turn on


Helllo
Will you please send me some more details about the fault? The description you have given here is very short to understand. Do the standbylight at the front of your TV lights up? Do you hear a small 'click' sound soon after you switched the tV's power On etc: Give me more details. OK.

Timer light will not stop flashing. can't turn on TV


Unfortunately the first generation DLP's from Mitsubishi are prone to have Capacitor failure through out the chassis. Most likely that is what your set is experiencing. I would start by replaceing the suspect caps on the DM amd The Power boards. You can get the V26 Chassis DM/Power repair kit from www.tvrepairworld.com which also contains instructions.

Call MITS, and try to get a tech to assist. Green timer flashing is "waiting for CPU to boot". Normally 70 seconds after plug-in. If doesn't stop, then not booting, and you won't be able to turn on. It only boots after being unplugged.

Continued from no picture no sound just clicking


The TV is on protect mode. The clicking sound is the protection switch that keep turning the TV off to prevent further damage, this happens when a fault had been detected.

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 an akai 27 lcd tv which shut down while watching. No sound no picture but the power switch is flashing red.I don;t know if it is a power supply problem or a burnt out backlight.I haven't opened the...


I would suggest to start by measuring the voltages from the power supply to the main/back light circuitry. If the voltages are low or jumping up and down, that means a defective power supply.
If the red light is blinking, the power supply has a shorted component.
Let me know if you need further assistance.

Tv keeps turning off?


cutta, you will most often hear a click on boot then the fans start up and lamp will then fire. The picture will start to show up....at what point does it shut off? and do you hear a click when the tv is turning off? Is it the complete tv shutting down, fans and everything that turns off? Do you see any lights on the the front panel "POWER", "STATUS" or "LAMP", what are they doing? If you see a Power, Status or Lamp light after it shuts off the below are what they mean if there is an issue. POWER - STATUS - LAMP - CONDITION/ISSUE: Off - Yellow - Off - Temp. high/dirty filter/excess room temp Off - Off - Yellow - 4000 hrs. Lamp usage warning Off - Off - Blink Yellow - Lamp Cover open Off - Blink Yellow - Off - Air Filter Cover open Off - Off - Red - Lamp failure (failed to turn On or broken) Off - Blink Red - Off - Fan Has Stopped Off - Red - Off - Circuit failure (short) or DVI cable disconnected If you want to check for the last "Error Code", after you first turn the TV on, by pressing the front panel ?DEVICE? and ?MENU? buttons at the same time and holding them for 5 seconds, it activates the Error Code Mode. The ?Power LED Light? blinks/flashes (1/2 sec delay) and then flashes again denoting a two digit Error Code indicating no problem or an error has occured since the last Initalization. i.e. "Power light" blinks 3 times (1/2 second delay) and then blinks 4 times then 1 sec delay and repeats a few times. This would mean "Error 34 - Lamp abnormality". See below for error codes..... Error Code - Description or issue 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 & Engine disconnected. Sorry for the long answer but it was an open ended question.

Power light flashing/ no picture


I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.
