Samsang hpr4252x/Xsan. Screen light but no pics


If the set is connected with a cable or sat box and or a receiver: Unplug set and box and or receiver from power for several minutes and power back---any of them locked up inside will cause this---I will presume you have checked for this on all inputs the set has.

LG PLASMA TV MADE A LOUD POP NOISE NOW PICTURE IS SNOWY


Hello,

A common problem for these is bad capacitors in the power supply, Remove the back from your TV and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps

Panasonic TH-42PX75U Blue Screen


This could be a reception problem of the cable transmission or the cable box if used. Are you using cable or SAT box. Tv goes to blue screen if signal is weak automatically.

My plasma LG TV has a black display box in the top left corner of screen. No words or text in it, just a black box covering that coirner of picture...how do I get rid of it?


There should be a button on your TV remote that will be called "Display" or "P in P".
The display button usually displays which input you have selected, such as: SAT for Satellite; AV1, AV2, AV3 or AV4 - depending on how many inputs your TV has, to plug in devices like a VCR or DVD recorder/player.
Otherwise, if you have a more sophisticated TV, it could be that you have accidentally pressed the "P in P" button, that selects the Picture in Picture mode. If you have done this, your TV will display the main picture of the input you have selected, plus another input, (such as SAT or AV1 or AV2 etc. as I've mentioned above). If the AV1 or AV2, etc. input is not active (not switched on) then that input will only display a blank (black) picture in the top left corner of the screen.
Hope this helps...

If it has not tuner/antenna input then it is just a monitor. At that point you will need a cable box,sat box or something to provide a picture scource to it.
