Try to go MENU, and restore to factory default and try it again.
If the problem persist, you must test the power supply, in order to see if the +5Vdc- 5 vdc+12vdc etc are there,
God bless you

Is Worth Fixing Panasonic PT-50LC13-K Rear Projector TV


most likely a bad mainboard or bad caps in the power supply. Borderline on the repair-ability. I would check Shopjimmy.com to see if used parts are available. If they are it may be worth it.

DSC W80.


Whenever you switch on the camera the lense comes out to a certain places, stops and the camera is initialized to take the picture. In some cases when there is a friction in the movement of the lense, it does not comes out fully up to the proper position. so the camera mechanism draws it back and again pushes it out. this happens 3-4 times and if still the lense does not reaches its position it displays "turn the power off and on again" and the problem continues.

Your camera needs a repair of the lense assembly.

Tv display black bar in the middle of the screen


I battled with this for a while before I realized that my 18 month year old had somehow turned on one of the less common closed caption modes. Since the mode was not supported, it just displays a black frame over most of the screen. Just turn it off and you are good to go.

Computer monitor comes on for 1 seconds, flashes "analog power save mode" and then goes black.


Most monitors will say "Power save mode" when they can tell through residual voltage that the signal lead is plugged into a machine, but there's no picture being transmitted. The four states of a monitor are:

* Off entirely.
* Switched on, plugged into a computer but no video signal being received - usually displays "analog power save mode" or "digital power save mode" for a few seconds, then blanks. Comes back to life the moment a video signal is received. This state is the default in full power saving mode.
* Switched on, not plugged into a computer. Some monitors don't display anything, some go into power saving mode, some fly "CHECK SIGNAL CABLE" or a similar message around the screen. Picture is restored when the signal cable is plugged back into the computer
* On fully, receiving an image, and displaying.

Hope this helps.

Panasonic PT-47WX49E


The only thing I can think of that would make the picture fade to black is a loose solder joint on the filament supply. Each of the 3 picture tubes has a filament and if the 6.3 volt supply to those filaments is suddenly lost, the picture fades to black as the filaments cool down. An experienced tech can find and correct this for you quite easily.
