buzzing from tv

[ssdmax87]

I have a 2010 jay flight G2 32bhds, I have a buzzing sound coming from the tv wheneve rI have it on, it does this no matter if using the antenna, or cable tv. I have turned off the power signal booster,but still there. The tv in the bunk house does not have this problem at all. I'm thinking it might be coming thru power supply. We have been to different campgrounds and same buzzing, so its in the trailer. Any ideas would be appreciated! Thanks for your time & effort! We love our Jayco!!!

I am assuming this HDTV is a 120VAC item and not a 12VDC item. I guess another question is how is the AUDIO OUTPUT of this HDTV used. Does it use the TV internal speakers or is connected to a home entertainment audio sound system.

For a quick test I would run an 120VAC extension cord into the the trailer from the camp ground pedestal and plug the HDTV into the 120VAC extension cord and have it using its internal speakers... If the HDTV sound has the HUM using its internal speaker using the pedestal 20AMP 120VAC source then I suspect the HDTV sound circuit is going bad on you...

Usually an AUDIO HUM occurs in the HDTV setups when you are connected to the cheap MSW INVERTERs running from your battery. This case however sounds like you are connected to the camp ground 120VAC source and not using an optional MSW INVERTER to watch HDTV with.

In our case we have our home entertainment system connected to a Pure Sine Wave 600 Watt INVERTER at all times that runs off the battery banks even when are connected to camp ground shore power. Since we camp most of the time off the power grid it just works out better for us to have the 120VAC home entertainment items always connected to our battery system using an INVERTER.

Just some thoughts on this end...
