    re: the processor monitors fans, nice little bit of info...

    This is the third lamp for this set, I always use bare bulb replacement into the original housing, although I admit it feels like it's getting a bit brittle from the heat.

    Nothing different this time around.

    When the lamp failed the fans did run, now there is no fan noise, nor air flow, although the pix is back.

    I'll pull the bits and check again.

This model monitors the fans, should one not work the set should not even turn the lamp on, leaving only the timer LED flashing. Recheck your work but you have had other problems to begin with. Be sure the covers are reinstalled properly. Are you getting a Temp LED that is lighting? If so then the Temp sensor needs to be replaced.

How to remove headlights to replace bulb on twin hella.

Most German type Hella lamps are removed from inside the hood/bonnet with a quarter turn twist, and then pull straight out, remove the wiring connector first and see which way it gives when turning gently. Replace your lamp with the proper replacement from OSRAM. They make more improved versions than the OEM includes with your car. Hella uses OSRAM/Sylvania (USA) bulbs as std.

Premature Lamp Blow

Have you been turning off this set from some OTHER power source, such as a cable box ? The set MUST have constant power for at least 3 minutes after turn off for the bulb to cool down. Also, do NOT use a generic "bargain bulb" to replace--either an original or a phillips one do NOT use an Osram "neolux" lamp, Mits. do NOT like them !!

Hi, your part # will be 915p020010. The original maker is Osram which last around 4000 hrs. You can get the Philips which last 6000-8000 hrs with a superior picture quality,only if you have the housing that has a white cart board covering the back of the lamp.If your housing is complete plastic you will have to get the original Osram. Here's the link where I found it:

Replacement lamp not bright

as i previously posted, my picture was dim, muddy looking after replacing lamp with osram lamp. i fixed mine by taking the screen off and cleaning the small mirror. it had a thick layer of dust on it, cleaned with a microfiber cloth. no water, no glass cleaners. i also used a very fine new small paint brush and dusted the projector lens which also had a dust film. brightness, contrast and clarity returned!

Mitsubishi wd 52725 lamp troubles

You can use Mitsubishi 915p020010 or Osram E023. Remove the front and clean the lense using only a clean microfiber cloth. dirty lense main cause of dark picture. The lamp could be incorrect wattage.

Burning out lamps on my 65inch dlp

I have 65" Mits. lamp lasted about 2+ years and burned out. bought new on internet, that lasted about 5 months and went. Got free replacement and that lasted about 4 months. No more free replacements ...

Bought new from different source and it burned out in a week.

Note: These were ALL OSRAM original lamps from reputable suppliers.

They sent a new one but also cautioned about cleaning the "filter" on the lamp housing. NOT the large screens on either side, but the small rectangular one (about 3/4" x 2"). I did this with a shop vac pulling and pushing from every angle and it was really clogged almost solid. No way air was going across the bulb to cool it.

THIS IS CRUCIAL and I feel is the keys to the kingdom! I did this and voila - no more "plastic smell" when installing the new lamp and everything's great!

I feel that Mits should be held accountable for this for not recommending the lamp housing be cleaned periodically (maybe yearly). I really feel if this were done with my original one it would have last a lot longer.
