Mitsubishi HDTV "bright spot" - need advice

... got a Mitsubishi 52" HDTV (Model WD-52525) new this past X-mas and I've noticed that there is a diagonal "bright spot" that has developed right in the center of the screen. It's only noticeable when showing dark scenes and/or when the room is dark... but very noticeable when the unit is $2000+!! I've tried adjusting contrast, brightness, etc., but it makes no difference to the intensity of the anomaly. There does not appear to be any discoloration--looks more like somebody is shining a flashlight (with almost dead batteries) at the screen from an angle. (I've ruled out glare from something in the room... Tried all imput sources and it's the same for them so it doesn’t seem to be in the signal. There's nothing magnetic near the TV so it's not that either.) You might not even notice it unless you were nit-picky like me but the TV is new and I don't want to see this much more pronounced about 48 hours after the warranty expires.

Has anybody else noticed this with this model or any other TVs? Could there be something on the bulb causing this? I hope that this is the issue but I would think that something on the bulb would create a dark spot (not a bright spot) and it seems to be too "focused" for something like that.

Any ideas or suggestions?--Thanks in advance.

I have never seen your particular TV so I don't know, but most direct-view CRT HDTVs have problems regarding localized magnetic screen discolorations that they simply hope buyers don't notice. I don't know the cause but I suspect they use magnets inside the television to try to get the image geometry reasonable on a flat screen (which goes against the natural design of TVs, which should have curved screens).

I only don't see discolorations of any sort on old analog small (20" or less) curved screen TVs or CRT computer monitors.

When in a Best Buy recently, I was lucky enough to catch all the HDTVs displaying a pure white screen, in which the discolorations were obvious. But according to you, your problem is more apparent when the screen is dark, not when it is light, so perhaps it is a different problem. Have you tried going back to the store and checking to see if their display units of your same TV have the same problem? (I realize it may be difficult as most stores have their TVs playing stupid source material that is not good for judging quality).

Thanks for the reply. The in-home warranty is still, of course, active so I had a guy from Sears come out and look at it. He said that this was "normal" and he went off on some spiel about how the television uses light to produce the image... (You're kidding!) Anyways... He basically said that the TV was within specs, told me that the professional opinion would have cost me $187 had that not been under warranty, talked about compression ratios for DBS, and then left. I was not impressed because I still don't like the bright spot. At the least, the anomoly is documented so if it gets worse later on, I can say I tried to get somebody to fix it. --Ted

I would still say that the next time you happen to be at Sears or whatever, check their display model of the same TV and see if you can try to spot the same thing (even though it may be difficult as they are likely to be playing source material that hides defects in TV sets).

Maybe you should repost this thread in the Rear Projection TVs forum. They might know more. Unfortunately I do not know much about RPs myself.
