New Ruby Bulb Dim?

I just installed a new bulb in my Ruby, and immediately thought the picture was not as bright as a new bulb should be, although definitely brighter than under the replaced bulb. (BTW, this is in a ceiling installation, and I'm damn proud of myself for pulling it off alone.) But after checking blu-rays and DIRECTV, I got back to a blank blue screen which definitely looked nicely bright. Fiddling with brightness/contrast didn't seem to help. Your thoughts, please. Some possibly important observations: my previous bulb (which was either my second or third, I can't recall) lost significant brightness suddenly....one minute I just had to get a new bulb; there didn't seem to be any tapering down. The lamp counter was in the 2,000s, but possibly had not been reset the last time a bulb had been replaced. But I'm sure until just a few days ago the picture seemed brighter than what I have with this new bulb.

Was this an OEM lamp with the Sony Logo and other office stuff on the box or was this an inexpensive replacement lamp made in china?

This was the real deal, purchased from the reputable B&H Photo; came in a SONY carton.

That would almost suggest a lamp power supply problem, except that usually they work well or not at all.

I would try an other "good" lamp if you can borrow one, and if the problem persists send the Ruby for service.

Sorry, that's probably not much of help...

Thanks...if I can't get "used to it" I guess it's off to Texas. Takes a helper to get it off the ceiling.

Have you contacted the place where you purchased the lamp? It could be defective...

No, but by tomorrow I might be ready to....having slept on it and checking today, I have no doubt this bulb is not as bright as it should be.

One last thought, remove the lamp housing and re-install. It could also be an alignment issue. Make sure the lamp house is seated properly. I know they do not leave much room for miss alignment that would mostly take place with the bulb itself and how it was put into the lamp cage but still worth checking. A new lamp should give you a nice bright image with renewed contrast. Fingers crossed.

I felt at the time my installation was done correctly, and as you say there doesn't seem much room for an improper installation. I just checked DIRECTV and the picture now looks as poor as it did under the replaced bulb. I have decided that trying to return the bulb will just waste time, assuming they allow a return. The solution is to send it to Laredo, where the SONY repair is. I've dealt with them twice, and they're good people. Fortunately I saved their packing from a few years ago. I had sent it to them packed myself, which led to about $500-$700 in repairs of breakage. UPS took the position my basic insurance of the parcel didn't cover customer-packed problem. My local UPS store man said to let him try with corporate -- and he wrangled me about $500! As luck would have it, the man who always helps me take it down and put it back up on the ceiling is on vacation for another twelve days; of course, this is not my main "TV" for program watching. And I admit there are a lot worse things that can happen to you in this world, as we all know.
