Have a Mitsubishi wd-73736. Plug in, the timer light blinks green rapidly then the lamp light blinks orange about 30 times. Press power button, smoke billows out back. I intend to fix myself. Advice?

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)

I have a wd-57731 The lamp light blinked orange. i replaced the lamp turned the tv on and the timer blinks green for one minute and then the lamp light blinks orange again. It won't turn on. Can you suggest anything?

There should be a system restore button on the front that you can use a ball point pen to press. If you hear a difference if operation (like the fans starting up) then you have reset the system. However if it does not come on and light up the screen then you are likely to have a bad lamp. The lamp has an access door either on the front or the back of the set and is usually on the back. Take the lamp out and inspect it for breakage inside the bulb. Also look very carefully at the root of the filament in the center for bubble like of the glass. If so it is bad and needs replacing. The best place I have found to get a lamp w/housing is pureglare.com

Hi,
It seems problem in power supply board that got few electrolytic capacitors leaky and causing problem. It does not look like lamp issue.
Let me know are you handy with electronics stuff repair and can replace parts in circuit board?
Thanks.

Mits has had an excessive number of problems with color wheels in some of their optical engines. Provided you replaced the lamp with OEM parts I would suspect the color wheel is causing the noise as well as the shutdown issues.

There are 3 different LEDs on the front of this televison. The TIMER will blink green. The STATUS will blink orange and the LAMP will flash red or orange depending on if there is a failure or if the lamp timer is showing over 5000 hours.

If I answer your question directly and the status is blinking a steady orange light, then you have left the side filter cover or the front lamp cover off or they are loose.

Also holding the menu and device buttons together until the timer light blinks will reveal a code that will help in diagnosing your problem. Goodluck.

Install The C26 DM and V26 Power repair kits available from www.tvrepairworld.com the kits contain the replacement capacitors and the CD with detailed repair instructions.

There is a tiny reset button to the left of the timer light. Press with a pin or something small, wait 60 seconds. Viola!

continuous blinking green light indicates that the capacitors have failed on the DM pwb. You need the V26 DLP DM repair kit which is available at the following link under their repair category.
