Screen light doesn't turn off

looks like a( DLP) tv digital light proccessor . aka projection. most likely the bulb is burned out . if so cost is $65-125 bucks. aftermarket bulbs are available online but some dont work or burn out prematurely. if you decide to fix it or buy a new tv ,invest in a surge protector. it will save your tv from problems like this . good luck.

key question is does power light come on and or stay on or not?

Hi
if everything light up except the screen that means your screen is either loose(if you drop the phone) or you need to change lcd as it got damage.

mcdevito75 here, I just imitated sleeping on a cell phne and found mine will turn off, try turning your cell phone off, (red button) and then turn it back on. If this doesn"t help call your cell phone carrier for their advise.

IM NOT FAMILIAR TO THE PHONE BUT TRY TAKING THE BATTERY OUT AND MAYBE BLOW ON IT.. IF NOT I HAVE NO IDEA?

frist wash the petrol and assid 2 check the display ok any more sent me mail [email protected]

my cell phone did the same thing, there is no solution-most likly caused by humitity, just send it in for a new cell phone.

First off, how do you know it's the keys, rather than something else? More details are always helpful. An important question is, can you see or hear anything at all, by any means? If someone calls you, does the screen light up?
If you see incoming calls, but can't answer them because the keys don't do anything, then I'd ask if the phone might have the keyboard locked. You'll be able to tell because you'll see "Unlock" in the lower left of the screen when someone calls or you press the power button (top left edge, above the screen). If it's locked, pressing the "..." button to the left of the wheel will tell you how to unlock it (just the "*" button down by the "0" button on my Blackjack).
If you don't see anything when someone calls, you might want to figure out if the phone is working at all.
A couple of ideas (sorry if any of these seem obvious - it's bad form to miss simple solutions):
1. Is the phone powered on? You can turn it on by holding down the power button (top left edge, above the screen) for several seconds. If you make it to 10 without the phone coming on, then it might be the screen, the battery, or the phone itself.
2. Is the battery dead? Try plugging the phone in and then holding down the power button, as above. If it still won't work, try removing the battery, then plugging it in and doing the same thing over again. When you plug the charger in, you should see a Duracell-like image on the screen, even if the phone is turned off. If you still don't get any sounds or anything on the screen, it sounds like the phone has serious trouble - probably needs professional help.
3. If you hear sounds ("swooshing" on mine) when you turn it on or off and the keyboard lights up, but don't see anything on the screen, it sounds like the screen might be bad - probably needs professional help.
4. Finally, you could try connecting it to your computer with the sync cable. I haven't done that with mine, so you'll have to read the instructioins, but it might let you know that the phone is working internally, but having communications problems through the keyboard and/or screen. If that's the case, you can try fixing it yourself or get an estimate from a professional. Good luck!
