1. Try this - hold the menu button down for 10 seconds. TV should power up; you will have to turn off front panel buttons on menu.

2. You can also try plugging in the TV through the USB on its panel to a computer or USB charger, and it may work. However, this is only a temporary solution.

3. Powering down the set or putting it in standby may have allowed the power supply to cool. Weak capacitors often go out of spec when they cool, thus preventing a section of the power supply from firing up properly again. There is a simple trick...just warm the back of the TV with a hair dryer for 5-7 mins after you have unplugged the TV. Look for the little areas of holes in the back panel of TV. Use these as your guide at where to use the hairdryer, but don't hold the dryer too close (say 5-6inches away). (Make sure the dryer is on High heat). If the TV doesn't turn on after you have heated it up (like it tries to come on but then turns off) you need to unplug the TV again, this resets it. And repeat those steps till it works. Resetting the TV after it fails to turn on is the key. Also, just leave the TV on. Don't turn in off. Since it is LCD, it doesn't take much power...only a few bucks extra a month for your utility bill.

4. A circuit board may crack about some of the larger components mounted on it. You can inspect the PCB's for fractures, and then repair them. It may also be poor soldering that has failed. I would be checking for these things first.


5. If you want to go in for a long term solution, you can easily replace the whole power board or just change the faulty capacitors. You will have to open the back panel and take a look. You can make out which are faulty, because their caps will be swollen on top. Here's a sample pic (not same model):

Check the specifications of the faulty capacitors, and get the replacements from your local electronics shop. If you are comfortable with this, you can use a pair of needle nose pliers to G-E-N-T-L-Y pull out the defunct capacitors. Once that is done, solder in the new capacitors carefully. If are unsure how to do this, try to get a friend who knows how to do this kinda stuff do it for you, or get a qualified technician. Warning: If you do not have a background in electronics repair, or are inexperienced, get a qualified technician to do it for you.

REMEMBER there are very dangerous voltages inside a TV that can KILL. Be sure to work SAFE when dealing with electricity. DISCONNECT THE POWER BEFORE YOU DO ANYTHING.

Hope that helps...Should you have any further questions, please feel free to post them here.

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.

you must check the light indicator if how many times does it blink which tell the main problem or the error code of the tv. either the power supply doesn't work normally or the lamp need replacement.

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
