That tv is very old and it just reached its life expectancy. It could be repaired but it will cost you more than a brand new tv. Black Friday coming up and you will find a great deal.

We heard a pop last night the screen went black but we can still hear and the tv turns off and on


Hi,
Most likely the loud pop that you heard was the lamp filament shattering and you can verify that by physically inspecting it,the UHP lamps have a life expectancy of 6000 to 8000 lamp hours when they are Phillips and from 3500 to 4500 lamp hours if it is an Osram,and you can find this items on discount-merchant.com or on Ebay

Sony full definition lcd model 1080


Yes you have a bad lamp. Unfortunately, I have noted that many dealers either "forget" to tell the customer that the lamp will require replacement, or they overstate the expected life of the lamp. The usual life of a lamp, as stated by Sony is 4000 to 8000 hours. There are 3 factors that effect lamp life:
1) the number of times the TV is turned on and off. Every turn on works the lamp very hard, so to make the lamp last longer, limit the number of turn on/turn off cycles. My rule of thumb is this: If you will be back to the TV within 30 minutes, leave it on.
2) Proper ventilation. In general the TV should have at least 6 inches of space on all sides to properly cool.
3) Power loss. If you have frequent power outages, buy a small UPS for the TV. The TV requires a "cool-down" cycle where the fans run to properly cool the set. If the cooling cycle is interrupted, it can effect lamp life.

Replace the lamp with and original Sony lamp and vacuum any openings you can see that are dusty and you should be good to go. Be sure to rate this solution. Thanks!

Plasma tv screen goes black once you turn it on. Only sound


I have a panasonic TH-42PX60U plasma TV. When I watch TV programing I have no problems, or with the DVD input. But if I switch to another input, be it video game (PS2) or vcr the screen sometimes goes black and the red power lcd light next to the power switch flashes. Holding the power button in for a few seconds will shut down the tv. Then I can turn it back on and it may operate normally again for a undetermined period of time, before the screen goes black again. This never happened when new. The tv is about 1 year old. Any ideas on this problem? Thanks Ernie
