Question about Panasonic PT-40LC12 40 in. LCD Television

1 Answer

Hard time turning tv on and once on, will turn off after a period of time

It usually takes 3 trys or more to turn the tv on. Each try the green light will flash for a while and then the red light blinks and the red lamp light will blink about every 4th time. Then when the tv turns on it will turn off again anywhere from immediately to a few hours of use at which time the red light blinks again along with the red lamp light. I seem to have an easiere time turning it on when it is warmer in the room. When I get home I turn the air on, so it's warm when I first get home. I tried switching out lamps. I had the lamp I took out when the "change lamp" light came on a year ago but get the same result. The tv worked fine before I moved but had it shipped in our last move and wonder if something go jarred loose.

Sounds like it may have been jarred or theres a larger tall capacitor in the power supply that goes bad in these sets alot. Its not something a layman should attemt. As a matter of fact the only thing in this set that is user replaceable, is the lamp. Sorry but your going to need the service manual and soecialized tools tom trouble shoot this set. you really should seek out a pro for this repair.

Tv won't turn on. red power light is out
red light is on, but when the tv is turned on, it immediately shut down and goes back to the red light setting. It is like it blows a fuse or something to that effect.Post Solution

Ps3 says cannot start the correct hard disk was not found
try safemode
hold down the power button while the console is in standby. the light will go from red to green.it will beep once flash green beep again, and then beep a third time. after the third beep the light will turn red.

once the light is red, take your finger off the power button and place it back on the power button. the light will go from red to green, beep once flash and then beep twice quickly. after it does the double beep, take your finge roff. the light will stay green and you'll get a screen asking you to connect the controller.

after connecting the controller, try option 3, or whichever option is restore filing system. this can possibly correct media loading and will 95% of the time fix the console when it freezes before loading up your icons(the xmb)
