Question about Mitsubishi WD-52525 52" Rear Projection HDTV
About two months ago I replaced the lamp and everything has been fine uptill now. when you turn the tv on the sounds comes on but now picture. Then after about a minute or two the TV shuts down and displays a red lamp light. (This only happens occationally. Sometimes the TV powers up fine and runs great.)
The replacement bulb was a different part number than on the back of the tv, but was supposed to fit my tv so the store said. When I received the bulb it was only the bulb and didn't come with the housing. I removed the old lamp from the original housing and installed the new bulb in the old housing.
I have been reading about different arc lengths could this be my problem or is it a ballast problem, or is it just a bad lamp?
What is the ballast and where is it located? Is it something I can change myself?
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
