We have a mitsubishi 735 series tv. When we power it on the mitsubishi sign comes on then the tv shuts off. We replaced the lamp bulb but that wasn't the problem. Any suggestions

hi make sure the lamp door is shut tight, thanks

Replace your lamp. Make sure its a real Osram bulb and not some cheap knock off. These folks have Osram bulbs and a 6mo warranty. Projector Lamps and TV Lampson Sale ProjectorLamps com stocks Superior...

The buzz may be coming from the ballast which powers the lamp--a few possible reasons: new lamp is generic or even bad. ballast is bad.

Also, do not rule out the possible dirt issue--these sets intake air from the front and the usual dust at the same time--fans and areas they vent become blocked and set will detect fans run too slow or temperature too high and shut set off.

To begin with in this situation in our shop we roll it outside and with air clean it completely out.

A few things to check and a place to start.

It sounds like the lamp in your "Mitsubishi Lamp-Cartridge" blew.

If your TV remains under warranty, you'll want to call Mitsubishi at 1-800-553-7278, and you'll need to have (a) Mitsubishi Model number, (b) serial number, (c) TV purchase date, and you'll have to ship the old lamp module back to Mitsubishi so that:
"All lamps replaced under warranty must be returned to Mitsubishi where they will be inspected for defect verification."

Return old Lamp-Cartridge to:

Mitsubishi Digital Electronics America
1001 Cherry Drive, Suite 2
Braselton, Georgia 30517

If you have trouble finding your TV's information, you need better "Warranty Management". Warranty Management can be done with software, or on paper. You may even choose to toss all your Owner's Manuals into a box, with the receipts. In case anything malfunctions/needs to be reprogrammed/reset then the manual & spare parts/cables (in a large Zip-Loc(R) baggie or two) can be quickly located and consulted.

If you television happens to be out of warranty, a nice (expensive) new lamp module can be ordered from Mitsubishi by calling 1-800-553-7278, or by ordering online at http://www.mitsuparts.com.

Refer to pages 75-76 of your Owner's Guide for complete Lamp-Cartridge module replacement instructions (with nice illustrations).

Your TV's Lamp-Cartridge part number is: Mitsubishi 915B403001

Here's an online source for the Mitsubishi 915B403001 Lamp-Cartridge:

Note that with the dlplamps.com offerings, you can purchase the lamp only for $109, or the entire lamp-cartridge module for $129. So you can save yourself $20 if you're handy. Remember to keep all fingerprints off the lamp glass element - this small amount of oil will weaken the glass, and cause premature failure of the lamp. In the event that you get a fingerprint on the lamp glass, erase it thoroughly with rubbing alcohol. Alternatively, one may prevent fingerprints with latex gloves (make sure you haven't an allergy to latex, though).

If the reason that the lamp blew turns out to have been a clogged Lamp-Cartridge Filter (once you have the Lamp-Cartridge out of the TV and in your hand, you'll be able to easily see the mesh filter), then place a regular PM (Preventative Maintenance) of this filter on your calendar.

That's the error indicating the lamp/ ballast fan has stopped working. You can get the Mitsubishi lamp / Ballast fan 299P321010 used in the V39 series DLP televisions. It comes with installation instructions and is available from www.tvrepairworld.com under the Mitsubishi DLP parts category.

Hi! it's either that the ballast is over heating or the fan is malfunctioning.

the lamp is simple; yet you can run into problems with this tv. be very careful replacing lamp. the plug in the tv can be damaged. (due to the design)

I had the same issue when replacing my lamp for the first time. I replace just the bulb with the Phillips replacement bulb. After installing the power down issue started and it would take up to 7 attempts before the TV would stay on with a picture.

Since I never had this problem until i replaced the bulb i decided to send the new bulb back and replace it with a difference one. In my opinion replacement parts are never made to the same standard as original OEM parts. This TV is definitely very temperamental in regard to the bulbs.

When the second replacement bulb arrived I decided to not only replace the bulb I also cleaned the connector plug in the cartridge with a QTip and alcohol. I did the same for the plug receptor in the TV.

When I replaced the bulb i insured the the top of bulb lettering was facing the handle of the cartridge so when you put the cartridge back in the TV the top of the bulb would be facing you.

I also cleaned the entire inside of the TV where the cartridge is inserted including the screws.

Once I did all this the TV turned on the first time and has been working fine for three days now.

I do believe the replacement bulb position is very important as to how it heats up and determines when it needs to cool.

I hope this helps others with the same success i had because I really do not want to replace this TV and start replacing all the parts others have done with little to no success for this issue.

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

OSRAM VS. PHILLIPS
This is about buying replacement bulbs for the WD62327 TVs.I dont know about the other models but I purchased a PHILLIPS replacement bulb and it worked for about a week and then those dumb flashing lights and no TV. I did some research and others were saying that you had to replace some condensers. Shop would do it for 600 dollars..Well i sent the bulb back and bought an OSRAM replaement bulb. The TV is now working perfect.
