Big spot on OPTOMA HD20 projection

Hi Luiz,

Interestingly i have exactly the same problem with my Optoma HD 20 - the orginal bulb blew after arround 3800 hrs and I put a new one in - after a few weeks I now have the same symptom of the transulcent black spot taking up most of the image. Keen to understand how you have resolved

thanks
Paul

Guys, it sounds to me like you used a "Generic" or so-called "compatible" lamp, which really WASN'T the CORRECT lamp for the projector and burned a lot hotter, causing the damage. I've heard of that happening to several other users who tried to save a few bucks on the lamp, only to destroy their projector.

Replacing the optical engine is NOT a cheap option. I'm surprised you're spending that kind of money on repairs instead of replacing the projector.

I'm surprised it was the OEM lamp, that's very unusual. Sorry for the assumption.

The price you were given for an optical engine is a lot cheaper than I have seen for other projectors.

I would reconsider leaving Optoma as they are one of the very few manufacturers who will sell you parts. Optoma and Panasonic are two that come to mind. Most only sell to authorized servicers and there some manufacturers who don't have parts, period. Dell is one.

Good luck with whatever route you take.

Hi Guys,

Unfortunately I did what Sheridan1952 surmised – I did install an non-oem lamp – I was told by the supplier it was the same OEM bulb as the original, but in a non-oem casing. I figured as long as the bulb was the same it should not be a problem.

Regrettably I have disposed of the original bulb so I can’t confirm the specs, but the lamp bulb I have is stamped as follows:

OSRAM
P-VIP 230/0.8 E20.8
Made in China

If someone can confirm this is different to the original lamp bulb I may have a case to go back to the supplier to pay for a new optical unit.

Loiz, I would be interested to get the details of who you spoke to at Optima and the part details as this looks like a far cheaper option for me than buying a whole new projector- did they give you any indication of when they may have stock? If you can send through to my email paul.roworth@hotmail.com it would be appreciated.

Many thanks
Paul

Sorry Loiz, just reread you response saying Optima won't have stock of the optical unit till march, so ignore that part of the response :-)

not really awake at all getting your name wrong twice, my appologies Luiz

Geez I'm a klutz, sorry, my email should be paul_roworth@hotmail.com - the dot version is the same as my work so it looks like I was auto pilot - appreciate your support and patience Luiz
