LG plasma buzzing

I have a new LG Plasma TV and recently hooked it up to FoxTel Australia's cable tv service. The cables from the cable box plug into the tv's red/white/yellow AV input sockets.
I now have a strong, low-frequency buzzing everytime I watch cable, and does not go away regardless of whether I use AV1 or AV2 red/white/yellow sockets. I get no buzzing from either regular antennae tv (free to air) or DVD player. It this likely something wrong with the tv (it's two months old) or has anyone ever heard of a cable signal delivering a low frequency buzzing. thanks

Problem is probably with your cable box as you have confirmed that the set is working by using the dvd player, that is unless you have a bad cable for the cable box.

Usually that is an indication of a faulty ground with the incoming cable. contact cable repair.

Why can't I get the DVD player to work? I have it hooked up to a cable box.


im wondering why you did not connect it to the tv ?? but instead to cable box , does it have a pass thru capability ?? does it need to be off to pass thru ?? as most dvd player don't have a rf output but instead use a hdmi or composite signal output , would it not be easier to connect one of these to a spare input on tv then when u want to use dvd you only need to select the proper input from tvs source button to view the dvd ??

My lg plasma tv is cutting off the edges of the shows we are watching. I cant find a setting that will take care of it. Can you help


hmm normally these settings are found in the picture settings of the set top box or just a setting in the tv's picture settings now there might be an option to say fill screen that may work best for some or leave the tv in 16:9 some broadcasts may only be in 4:3 at times this is normal broadcasting and not much can be done unless the setting on the picture option is set to fill screen

I have pioneer plasma tv about 6 years old. I turned the power on, sound but no picture. Do you think it is worth fixing?


no
plasma tv units consume considerable power and the latest led units don't so for the extra cost of a new unit , there will be a power saving over the years

Where can I purchase the Audio Video Connection for my dvd player I want to hook it up to my TV but can't find the correct cable Thank you Sandy


For the COBY TF-DVD7500, the video is carried on a single RCA plug cable. You can make due with a composite video cable (with three RCA plugs on each end) or get an RCA cable. The audio output can either be digital audio (which uses a special coax cable) or a headphone connector (analog audio).I believe the headphone jack is a 3.5 mm connector. If you use a composite video cable to your TV, you can connect the red and white plugs to an adapter (3.5 mm M to 2 RCA F). Then the TV speakers will get the audio track; otherwise you can use the DVD player speakers or the digital audio out.

I hope this helps.
