There is a lamp cover on the back that only requires a few screws to remove. the lamp is behine there, you will need a standard screwdriver to remove the lamp and inspect it. If indeed the lamp is bad you will see it shattered and/or burned at the tip. The timer light flashing for 30 seconds is normal as the TV is going thorugh a boot up process. One word of advise, don't touch the glass part of the lamp pnly the case.

Mitsubishi wd-73738 turns itself back on


It sound like the remote is powering off the cable box but not the TV. The remote control may need to be reprogrammed to the TV. When you press power it may only power off the Cable box. At that point, try pressing the TV button on your remote and then Power. If it does not power off the tV after pressing the tV button, the remote may need to be reprogrammed to the tv. Cable companies usually have the codes needed to program their remotes to the TVs.

My mitsubishi wd-65c8 has a flashing green light.. I have replaced the capacitors on the DM board and the same is happening.. what else could be the...

Common Repairs
For the following models: WD-52631, WD-57731, WD-65731, WD-Y57, WD-Y65, WD-57732, WD-65732, WD-57831, WD-65831, the most common repair problem stems from television shutting off almost immediately after it has been turned on accompanied by the message, "TV will shut down in a few seconds. Please check if the air flow is blocked." According to the Mitsubishi website, this issue is caused by a loose connection as a result of a faulty thermal sensor. For models: WD-73727, WD-73827, WD-73927, WD-73732, WD-7383, the most encountered repair problem has been in relation to the optical engine. Another common situation consumers have encountered is failure of the TV to turn on along with unceasing flashing of the green power light. The solution for this problem, caused by the DM board, will vary by repairman. Consumers have also encountered issues with moving vertical or horizontal lines appearing on the screen which can either be due to problems with the capacitor, light engine, or formatter board. Make sure all bad caps are changed.

Model WD-57731 LED Timer Light

You have a dm board problem could be the capacitors or you may need to change the entire board.

Continuous green flashing light

ther are some bad capacitors on the dm board in this tv, but this model is not layman friendly, we usually send in the entire chassis to Mitsubishi for a rebuild this cost about $300 then there is the cost of service also, this job will probably cost around $5 or 600 dollars.
