    Tried the RESET routine, no effect. Same syptoms as before, RED power light lit, no screen, no sound. Pressing the powere button on remotemake the power LED blink each time you press the power button, otherwise no other response from unit.

Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

I have a Sharp flat - clip_image001.jpg
1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

Hope this may help;

Regards,

    This a cold solder issues - each component is soldered into small holes on the printed circuit board which in turn connects said component to the other components. Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the TV turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough.

    Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder".

    Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing....

    Good luck:

HAVE AN BLINKING CODE OF 2 SHORT 3 LONG UNIT ITSELF MAKES A (POWER) CLICKING NOISE WHEN I TURN ON IS THIS SYMPTOMS OF A T-CON BOARD REPLACEMENT OR PERHAPS A POWER DIST. PROBLEM


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
http://electro-medical.blogspot.com/
If blinks continue without any pause, the main board is faulty.

My 73" mitsubishi dlp WD-73827 turns off and has a red status light blinking. I have replaced the bulb and the heat sensor... any answer to what else could be the problem?


It is helpful to have the sequence of the blinking red light. This may help:

MODELS: WD-52627 / 52628 / 62627 / 62628 / 62827 / 62927 / 73727 / 73827 / 73927

3. Error Code Operational Check

Note: The TV must be in "Shut Down" and not have been switched Off, to perform the Error Code Operational

Check. When the TV is switched Off, the code automatically resets to "12" No Error.



Pressing the front panel "DEVICE" and "MENU" buttons at the same time, and holding for 5 seconds,

activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem

has occured since the last Initalization.



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.

• The Error Code is repeated a total of 5 times.



Example: If the Error Code is "23", the LED will flash two times, pause, and then flash three times.

I have a Mitsubishi WD-62525. This morning my TV would not turn on so I pressed the rest button. After the Timer light stopped blinking I pressed power. I could hear the fans start than a somewhat loud...


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
