I have the WD 62627 model. the lamp light is on, when i power up the tv, it comes on for like 6 to 10 secs then it turns off. Does this mean I need a new Lamp?

Those blinks are fault indications. From the number of blinks occur at one time switch on, you can get an idea about the fault circuit section inside it. http://electronicshelponline.blogspot.com/ Visit the site linked here to know more details about the blinking codes.

Your lamp cover is not installed. That is what causes the LED to light amber. Remove and re-seat the lamp cover door. There is a switch it hits to tell the TV the door is shut. This is to protect you from electrocution.

should be in the manual. Or you can look on line for Mitsubishi model wd62627 owners manual download.

major circuit problem, time for a flatscreen

Inspect the lamp first to see if shattered--set has a self check feature also:

Here's something that might also be useful. After you turn on the set, and getthe regular red blinky lights, hold down the Device and Menu buttons togetherfor about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filtercover 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 cablebetween FMT and Engine disconnected

Replace the lamp of your tv or check it first if damage, feel free to send feed back good day and best regards.

it sounds like the lamp is not seating right, make sure it is, try unplugging the tv instead of messing with the lamp if it powers on then you are better off calling a tv shop.

Try this:
1) turn on the TV
2) from the remote control press MENU 2,4,7,0 then ENTER
3) tv will state on screen that it is INITIALIZING
4) when done press the front reset button.
5) should be good to go!

the lamp is simple; yet you can run into problems with this tv. be very careful replacing lamp. the plug in the tv can be damaged. (due to the design)

usually with that model when you get a 34 eror code for lamp abnormality, its directly related to the capacitors on the Power Pwb. You can get the V26 Power PWB repair kit at the following link which repairs that issue. It contains the replacement High temp capacitors with the board location numbers and PWB identification as well as the service manual on CD. Heres the link its under their repair kit ctegory.
