Every few minutes the sound drops out for a couple of seconds. Tv is a Sony and I am watching via sky


Does the TV do this no matter the video source, for instance does it do it when you watch a DVD? If the sound is steady on other video inputs then the TV is not the problem.

Turn off protect mode tv


It sounds that the TV's internal circuit board has some loose solder terminals. You have to re-solder them. In most cases, these faults are related to main power supply regulator board.

That's a broadcast signal issue not TV issue. If it was the TV all channels would be the same.

My 31GT740 tv's picture is taking up to 5 minutes to come on...


There is possibly a loose solder joint in the horizontal drive circuit. There is a little coupling coil just before the horizontal output that will get loose. This should not be real expensive to have repaired.

No sound


Hi, Probably you first have to determine if the "no sound" is the TV or your source (cable box). Try another source such as a DVD player hooked to the audio/video inputs of the TV, if still no sound then you have confirmed that it is the TV, if there is sound, then it is the cable box (in some cases it may be just the cables connecting the cable box and the TV; try wiggling it a bit, might just be loose). If it is the TV, go through the routine of the setup/menu; look for audio, stereo, SAP, etc, try different settings (pls log down original setting in case no change and you have to revert back). If all else fails, try the "thump test" this will help you determine if its a loose/cold solder problem inside the TV. Give your TV a good whack at the side, top or back, if sounds comes on even briefly, it's a loose/cold solder problem, if not then you probably have to have the unit serviced by a qualified professional. Good luck and kind regards.

Model 2780R intermittant Picture & Sound Failure


The set has loose power conections to the tuner and judging by the model it might have other loose conections in the chassis,the loose conections need to be resoldered and might not be easy to find,try taping the side of the set to see if it reacts while is doing the problem.Be safe and call a technician unless you are familiar with tv service.
