What is the red light on my wd-60737 mean? - Mitsubishi WD-60737 60 in. HDTV

Hm Code 12 is "no error". Which is odd since you have an error.

However, since the age of the TV is around 7 years, you may have the problem that the power supply is known for. The capacitors in the power supply fail.

To be safe, check the lamp and make sure its in good order. May want to change it anyway if its more than a year or 2.

I have a Mitsubishi model WD-60737 and to make a long story short 1st time problem lamp replaced fine for a month til my uncle hooked a DVD player to my TV next day turned on with solid green light then TV kept turning off after 2 to 3 minutes of beingetting turned on and a solid red light to show after. What does that mean? It's a brand new lamp and worked for a month so why shut down now? Could my uncle have did something to where it shook up the circuits or something?

Is this a projector? WD-60737 ?

The set has power, and the power regulator section inside is working well, but there is no working of main board.

Mitsubishi TV troubleshooting
Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for 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 filter cover 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 cable between FMT and Engine disconnected

The orange blinking light means a light bulb needs to be replaced. You should go to a Mitsubishi store and see if you can get one. Good luck
Take the old one with if you can get it out.

the optical block is an integral part of the light engine which is the large black plastic unit that the lamp shines into.
