Sounds like corrupted firmware. Contact any service technician. However, try a reset to this set, and check before doing a firmware update. There are two types of reset to TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight; will be better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done

SOURCE: mitsubishi wd-73837 doesn't turn on at all, no

I'm sure it's nothing you did wrong. I maybe a blown fuse inside causing the problem or a bad power supply. But, I wouldn't open up the TV. It may void the warranty by playing around inside.
Best to take it back and exchange it for another one. Tv repairs now and days cost an arm and a leg. Use warranty to full advantage.

SOURCE: I get sound but no picture then the tv shuts off after 5min. It is a Mitsubishi wd-73837

Popping noises are not a good sign; I suspect the sound came from the catastrophic death of an electrolytic capacitor or worse, the death a a power semiconductor.
Open the lower cabinet and using a good light, look for a smaller, separate board with fairly large parts on it; some cylindrical in shape, others block-like that may have copper wire showing.
If, as common, this board is plugged with connectors into other parts of the system, you may be able to swap the failed board out for a replacement bought from a Mitsubishi service center.Expect to pay $100-$150 US if the set is no longer under warranty.

blinking yellow indicates no lamp or the lamp door is open. if you had the back off you may have gotten the door switch aligned improperly. the door switch is located just inside the lamp door.
the lamp may also be bad.

Timer is on and Tv will not come on


Press the System Reset Button which is on the RHS on control panel
If the TV fails to respond to the remote control, control panel
buttons, or will not power on/off, press the SYSTEM RESET button on the control panel.
The green LED on the front panel will flash quickly for up to one and a half minutes. When the green LED stops flashing, you may turn on the TV. Recent setting changes you made before using SYSTEM RESET may be lost.
If that fails try pressing and holding the menu button for 8 secs

RESET Mitsubishi WD-65837


The set aside from a reset button recessed on front (some do and some do not) has at least 2 hidden menus= adjustment and OPTION MENU---option menu will do a hard reset of the entire set---but it requires a 4 digit number code by model---being 1500 miles away from my paper files I have a suggestion.

You can search to see if can find (I strongly doubt Mitsubishi will tell you) the entry code for your model.

Some of these sets also had a soft reset (no harm trying) and it is with the set turned on and using the Mitsubishi remote (also needed for hard reset) Menu, 1,2,3 enter.

That ought to be at least tried and the OPTION menu is usually last resort here---

Mitsubishi wd62526 tv has a passcode on it that i dont know ;so is there a way to change it or reset it


Bypassing the V-Chip Lock After you set the lock, you need your passcode to view a V-Chip locked program, view the locked TV, cancel the lock, or enter the V-Chip Lock menus. If you forget your passcode, you can view the locked TV without entering your passcode. This is done by pressing the number 9 and QV buttons on the TV remote control at the same time, when your passcode is requested. This process temporarily unlocks the TV. When entering the V-Chip Lock menu, this process deletes your old passcode and prompts you to enter a new passcode. Press HOME to exit the menu.

Bypassing Front Button Lock If you have misplaced the remote control, you can bypass the front button lock by pressing and holding the MENU button on the front panel for more than 8 seconds
