Why are you mad, it's probably overdue for replacement.

Getting a free replacement bulb would basically mean you started out with a defective bulb, so I'm happy that I didn't get my free replacement...

I looked at some past posts in this thread but didn't see anything directly related to my problem.

I have a WD65-838 that's about three years old with about 5250 hours on it. I decided to replace the bulb with this link on Newegg:

http://www.newegg.com/Product/Product.aspx?Item=9SIA07905Y9420

Says original Mitsubishi replacement lamp 915B441001 and comes with a Oscam bulb - actually sold by Ness Electronics which is AKA shopjimmy.

Received and replaced. It worked for about a minute or two then the screen started flickering in a green/cyan tone and make a clicking noise. Put the old bulb back in and the set works fine.

I called Ness and was told that this is a KNOWN problem with this model and Oscam replacement bullbs. The color wheel detects a problem and goes nuts. Not sure it happens with every Oscam bulb but it happened to mine. Ness emailed a prepaid UPS return sticker for the item and is sending me a Phillips replacement bulb which they say should solve the problem. I'll have to wait and see.

Anyone else have this problem?

lloyd, that sounds exactly like the problem I had with one of the non-OEM replacement bulbs I received. Upon initial startup it worked for several minutes, then it went into that state. I shut off the TV and let it sit for a few minutes, turned it back on and in a few minutes it did it again. I swapped bulbs and the set was fine. Switched back, and the same behavior. Keep trying and hopefully you'll get a good one.

Back here I mentioned I was trying yet another OEM bulb. I still feel like it's dimmer than what my original bulb was.

I never thought to look at newegg. I'll have to remember that for the future.
post #8766 of 8788
Thanks for the reply Keith - not sure why the color wheel would be so fussy to what the bulb is doing. Seeing how it take a minute or two to screw up the color wheel the bulb must be changing once heated up - drawing more current or less (?) and why some bulbs - like my original or a replacement that you finally installed - don't cause this problem.

My question is if it's a KNOWN problem with your model WTH do they offer the Osram lamp for it?rolleyes.gif JMHO

My guess is that tolerances could be slightly different either in the sets themselves or in the Oscam bulbs or a combination of the two. Maybe some work fine - maybe most work fine - but not mine or Keith's.

Could be the Phillips won't work in mine either.

Please let us know how it performs. Good luck!

I always recommend getting your replacement lamps from Mitsubishi. I've read many reports here in the forums of TV troubles with aftermarket lamps. They can even damage your TV and void your warranty. Saving a few bucks isn't worth it if the lamps don't work correctly.

IMHO, I don't think it's necessary to buy direct from Mitsubishi. Mitsubishi doesn't make the bulb - they use a Osram P-VIP 150-180/1.0 E22RA which can be purchased from many other suppliers. I compared the original bulb that came with my set to the replacement I got from Ness and they are identical. I don't think Sylvania makes a special version just for Mitsubishi - if they do I can't detect any difference with the labeling. The lamps that Mitsubishi warns about not using are knock offs made by other companies.

After my replacement from Ness didn't work correctly I tried swapping out the lamp holders thinking that might contribute somehow to the problem but got the same results. Swapping out the bulbs was fairly simple so in the future I would only order the bare bulb - that is - if the new Phillips they send works. If not I'm not sure what I will do - maybe keep exchanging until I get one that works.

I was thinking about this and how the color wheel is causing a problem with the new bulb. The color wheel has a reference mark and a light sensor to detect its position. Seeing how the problem doesn't start until the bulb has warmed up and reached full brightness maybe the photo sensor is overwhelmed by the new bulb's intensity and can't detect the reference mark due to a coating of haze that's built up on it over time. There is a YouTube video about how to clean and prevent this haze build up. The original bulb still works as its output has dimmed with use. Just a theory that's probably wrong.

Live and learn. I sincerely hope you get it working.

SUCCESS! The Phillips works great.

If you need to buy a replacement bulb I would definitely buy a Phillips.

I didn't mention this before but I actually tried two original Osram bulls with the same bad results.

I had purchased a genuine replacement bulb - Osram - two and a half years ago to have on hand just in case the original failed, When I tried it a few weeks ago I got the flashing blue/green screen from a malfunctioning color wheel. Since it had been long out of warranty I ordered another from NESS but got the same results. The Phillips replacement that NESS sent works better than new..

Thanks for the update, appreciate it! I'll be going with a Philips when I order!

So did Ness (shopjimmy) send you a sealed Mitsubishi OEM lamp housing with Phillips bulb or did you just swap out the bare bulb in the OEM housing?

They sent the complete housing and bulb - in fact, the Phillips came in a much nicer shipper box - much better protected than the Osram. But, as I mentioned in a previous post, I would only order the bulb in the future and save about $10. EDIT - actually save about $20.

My Mitsubishi definitely needs the Phillips bulb - not sure every 738/838 does but it's only about $11 more for the Phillips so why take a chance.

I just ordered one from Shopjimmy ($104.39) as well for my 65738. I have an extra lamp assembly for all my Mitsubishi TV's except for this one and was going to order from Mitsubishi but since they jacked up their prices I thought to order from Shopjimmy after reading these posts. Thanks for letting us know about the Philips and Shopjimmy.

Strange !, I just put a new lamp in and the values for brightness had to be lowered by 15 from the factory setting of 31 ( I use 27 on new bulbs) this was using the natural mode with the standard lamp setting. It was the same on all inputs , anyone got any ideas why i have a super bulb on my hands?

Its one of the two I got from Mits last year upon hearing about their exit and suspecting an eventual price hike!Model numbers for the lamps confirmed and I haven't tested the other yet ( I know I should've tongue.gif) I'm going to try a factory reset to see if somethings a miss, I ran it all day yesterday for 12hrs and did notice perhaps a bit more fan noise and the usual more when switching from standard to bright! I'll post back what I find but still curious as to why wink.gif

Ha! after two days of what I'm assuming are normal viewing and power ups and downs, all is back in spec smile.gif none the less I shall indeed report the life of this one wink.gif

post #8785 of 8788
Blah, i'm frustrated...

I owned an original 62725 - the ones with the defective capacitors. that died just after 5 years. Mits offered me the new 65738 for $700, which i took. that was 4-5 years ago.

the bulb just died last week wed. 7330 hours on original bulb.

so i plop on over to amazon, since i have Prime, and order this POS...

http://www.amazon.com/gp/product/B0051WTMJ2/ref=oh_details_o02_s00_i01?ie=UTF8&psc=1

I get it 2nd day, which is awesome. put it in, Friday, and it's fantastic for abt 15 mins. then the image degrades, flickers, green/blue... whirling noise. i turn it off.

rinse and repeat, no dice. reset, no dice. reseat the lamp, leave power plug off, yada yada... give up. request RMA.

order original Phillips here...

http://www.amazon.com/gp/product/B00BBFYC8E/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1

received today, MOnday. it's an original Phillips - warranty card, stamp on bulb, ect...

put it in and is great for 15 mins. then shuts of by itself.

no matter what I try, the picture is great and looks perfect, but will shut off after a few mins. i'm thinking the first generic bulb was too hot and screwed something up??

***
Update: Tues 4/1, tried turning on the TV after work, the TV made a series of "clicking" sounds, as if the bulb was trying to fire up. After it ran it's course, I removed the Phillips bulb and there is glass shards inside the bulb.

Any thoughts?

I appreciate any advice you can give.

Thanks.

~Eric
post #8786 of 8788
kevang, your experience with that first replacement is not that uncommon, I had something similar happen. The next bulb I got was too dim, the next one was ok. It just seems hit or miss with the generics in particular. I doubt it had anything to do with the failure of the next bulb you tried.
post #8787 of 8788
I was always skeptical of those that said dlp lamps would dim. I thought they must be videophiles that are noticing maybe the slightest changes. My lamp had 10,300 hours on it, so I thought I would get a new one and see if there was a difference. Wow, I feel like I just bought myself a new tv with the new lamp. My eyes must have been adjusting to the lamp dimming, because the new lamp makes my 65738 look amazing. Off axis viewing is also great. I'll buy my next new lamp much sooner.
post #8788 of 8788
I have somewhere around 5-5500 hours and I already see a noticeable difference in brightness. In day to day tv it is fine, but on movies, especially dark scenes, it is almost unwatchable. I swung by Shopjimmy this week and picked up a new phillips bulb for it, but was planning on waiting until this one died, or I just couldn't take it anymore.

I had $25 credit there for some reason, so it was about $50 for the new bulb.
