I have a Mitsubishi wd-73734' and lately the unit powers off and the red timer indicator is flashing on the front panel. After unplugging set for a few hours it works ok,what is causing this thank any info appreciated. [email protected]

No TVs will behave that way due to a timer. TVs only will display a nag screen telling you to reset the timer. If your lamp is more than 2 years old, it is suspect of failure. Be sure you buy a lamp with an Osram brand or Philips brand bulb inside. Any compatible(knockoff)lamps will not perform as they should. Mitsubishi DLP TV Bulbs
These folks sell original Osram bulbs in their lamps and they have a 6 month warranty. I use them myself for repairs and really have had great experiences with them.

Try a reset. Start by unplugging for 1 minute, then plug back in & if still won't restart try the following. If none of the following work, you will need a technician.

Initializing the TV in many cases can remedy a problem.
In the 2006 product line Initialization is now a user function.
Pressing the front panel "INPUT' and "FORMAT"
buttons at the same time activates Initialization. When
complete all user settings will have to be set again. The
table in Figure 4-3 list the User Initialization procedures.
Note: Pressing INPUT and FORMAT is the same as
the Initialization in the Option Menu (MENU-2-4-7-0)

LED Indications

The front panel Status LED provides an indication of

the set's operation and the possible cause of a malfunction.

If an abnormal condition is indicated, perform the

Self Diagnostics procedure.

Self Diagnostics

To activate, press the front panel <ACTIVITY> &<CH

??> buttons at the same time and hold for 5 seconds.

The STATUS LED will then flash denoting a two digit

code.

• 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

(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.

Table 2-2: LED Indications

Error Codes, descriiptions and the most likely cause of

the error are listed in Table 2-3.

Note: The TV must be in "Shut Down." The LED

will probably be indicating an abnormal

condition. If the TV is switched Off, AC is

removed, or a System Reset is performed, the

code automatically resets to "12" No Error.

See the Error Code Log to retrieve a history of

errors.

Note: Use the front panel buttons, not the remote

control.

Note: If there is no response, the front panel may be

locked by a V-Chip setting. To unlock, press

and hold <ACTIVITY> on the front panel for

8 seconds.

9 PERCENT IS YOU MAIM BOAR

The status light blinking red is indicating that a fan has stopped. which is not allowing the set to power up.

You probably have a bad lamp again I hate to say. These lamp are so critical when being moved. If after you atttempt to power on TV then red light shows, press menu+input on the front panel and hold for 5 seconds. Front timer LED will blink a 2 digit error code five times then stop. Code 34 and 66 are lamp errors, and if you read code 66 the lamp is broken. Good luck

Try to reinitialize the set , with the remote press menu 1 2 3 enter.

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

I RECENTLY HAD A LAMP ISSUE THAT MAY ASSIST. I HAVE A MITSUBISHI WD-52525 52" DLP. I HAVE OWNED THE UNIT JUST OVE THREE YEARS. THE UNIT INDICATED THAT THE LAMP NEEDED TO BE REPLACED WHEN THE UNIT WAS TURNED ON. I ORDERED A LAMP AND BEFORE IT CAME IN THE UNIT QUIT WORKING. I REPLACED THE LAMP AND WHEN I POWERED UP THE UNIT I GOT A STEADY YELLOW INDICATION AND THEN A SOLID RED. MITSUBISHI TECH ADVICE STATED THAT I MAY HAVE BEEN SHIPPED A BAD REPLACEMENT LAMP. I SENT THE LAMP BACK AND ANOTHER WAS SENT TO ME. THAT LAMP ALSO GAVE THE SAME RESULTS. I CALLED CHUCKS ELECTRONIC REPAIR AND A VERY KNOWLEDGABLE TECHNICIAN RESPONDED TO MY HOME. IT WAS DISCOVERED THAT THE POWER SUPPLY BOARD WAS BAD AND THAT THE LAMP NEVER NEEDED TO BE REPLACED. I SPOKE WITH REPRESENTATIVES AT MITSUBISHI SEVERAL TIMES AND THIS WAS NEVER EXPLAINED TO BE A POSSIBITLY. THE TECHS AT MITUSBISHI BASICALLY JUST READ FROM THE OWNER MANUEL AND HAD NO IDEA WHAT THEY WERE DOING.
