I'm going solely on ottoinct's experience and reviews I saw on Amazon, but I am assuming (hoping?) it's not difficult. I purchased the Osram bulb from Dynamic Lamps through Amazon.com. Strong seller scores and Amazon return policy.

I saw them (dynamic lamps) I think the bulb was around $18. I'm assuming it's the right bulb for my model. Is there anything special I should know about installing the bulb in the housing?

Thanks for the reply and advice.

My Osram bulb arrived and I followed the fairly simple and obvious steps in this video
Don't touch your new bulb. You will need gloves, and a magnetic screwdriver. Securing that wire at the end is tight. Unplug your TV and don't remove the old bulb until it's been off for at least an hour.

It only took about 10 minutes and was easy, except in my case, in the very first step, both of the plastic tabs snapped off when I tried to pry the assembly open. The good news is that the cover snapped back together anyway and it feels pretty tight, despite having those little pieces broken off. I would be very surprised if it created any problem.

The Osram bulb appears to be identical the the OEM bulb that it replaced, and was half the price of a whole assembly, so I'm a fan so far. It fired up and is definitely brighter than the old one. Will put it through it's paces in the weeks ahead.

For what it's worth, I spotted this Guide for spotting counterfeit projection lamps, but only after I installed the bulb, and I'm not taking it apart again just to check. If anybody else orders, it would be interesting to run it through this checklist.

7 Tips for spotting counterfeit projector lamps...

...7. Naked bulbs, no cage

Counterfeit lamps are often sold with no cage just the light bulb. Phillips has authorized MI Technologies to sell their replacement bulbs since this company also manufactures its own cages. It’s this is a rare exception to the rule, however. Most companies selling only light bulbs are selling counterfeits.

philips lamp

I know their are lots of threads about bulbs but I haven't found this before
I installed a new Philips lamp in a working wd 82738 tv the new bulb worked great for about 5-10 min then started flickering and getting weird looking.
I returned for a replacement and it did the same thing . I returned it I don't think they are knockoffs as they weren't cheap($90,)
Has anyone seen this problem before Ii order a new lamp from Mitsu?


Thanks for any help

I had that with the first bulb I changed. It was a loose bulb that I had to install in the assembly myself. I assumed the worst but before I threw in the towel I removed, disassembled then reassembled everything. I paid extra close attention to the electrical connection points and made sure they were as tight as possible. I worked for three years and a month before it popped two weeks ago.

I bought my replacement bulb from batteries plus. It took four business days for the bulb to arrive. I can't vouch for its authenticity but it's the complete unit, out the door, for $71. There are some minor differences between the original and new assembly but it was plug and play and works great. This TV with a new bulb is still a great unit(65738). I even spent yesterday afternoon mucking about in the "Manual Geometry" section of the service menu. I should have done that yeas ago.

I only use Mitsu lamps. They're not as expensive when you consider they are actually spec'ed for the TV, and how long they last, vs. bad lamps and possible TV damage when you roll the dice on aftermarket junk. To save what? $50-$80, over a two or three year period? I spend more than that for a month of cell phone use.

You said you replaced the bulb in a working set. Does that mean the original still works?

Yes the original bulb still works. I just wanted to be proactive and replace it before it dies.
I have had the tv for several years, not sure how to see how many hours the bulb has on it .

That would leave me to believe that the bulbs are either bad or incorrect for the set. The first time I replaced my bulb I accidentally ordered the wrong one. It was identical in appearance to the original. If you want to get one that, barring TV issues, is sure to work; order from Mitsubishi.
