I have the same TV - I have a dark spot in the upper left hand corner. I have always thought this TV was dark. Be sure to get OME lamp. Cheaper ones are not worth it and can damage your TV more. dlplampsource,com--Just a note if this ever happens to you. TV would not come on in the AM-Had no picture, but had sound. It was not the lamp, but the safety switch. It's blue and at the bottom of the lamp housing. As soon as I flipped it and replaced the back cover, the TV came on.
This problem seem to be the LCD screen have dead pixels or a bruise spots on the LCD screen itself that why you have dark spot or spots on the LCD Screen.This problems can't be repair because this problems doesn't causes by the electronic circuit boards.Tried move the monitor as an angles to the right or to the left might help some lessen the dark spot on the LCD screen that all you could do.If this problems is a very dard bruised spot will not help all or if it is dead pixels on the LCD screen itself.
The back light is the whole of the screen, the screen is illuminated by a CCFL lamp (fluro tube) on the bottom of the screen. A inverter supplies high voltage to this CCFL lamp. If
your laptop appears to boot up and the hard disk LED flashes, then the
problem is probably a back light fault. This can be a faulty inverter or a
faulty CCFL lamp. Please click on this link and follow my instructions

It could be a power supply problem or an inverter board problem or something internal having to do with the backlighting of the unit. remove the inverter, and look at the back side and you will see a hot spot, now on the other side of that hot spot, re-solder the service mounted components and that should take care of your problem.
Please get back to us if you have further query else please accept the suggestion.
quote:"The spot was too hot to keep my finger on it while the rest of the
screen was cool" You have a partial hardware failure on the lcd's internal circuitry (column and row drivers, stuff like that). The short time it's working is about the overcurrent protection delay, it cutt's itself the Vcc, Vdd and control signals for limiting the fire hazard.
