I am an owner of an 35" color tv and the picture goes fuzzy and buzzes with a loud noise for a few minutes into the show, this continues to happen as long as he tv is on. I can wiggle or hold the antenna connection or the antenna wire in the back and the picture clears right up, once I release either the tv starts to mess up again. I look forward to hearing from you soon.

Re: RCA 35" Home Theatre
You have diagnossed the problem by moving the antenna imput,the problem might be a loose conection in the tuner itself,the grounds ussually get loose and need to be resoldered,if you are familiar with tv service you can resolder all the pins and grounds,there is another possibilty and that is the conector itself where the antenna screws is loose and it has broken the solder conection inside the tuner and the will have to be taken apart and resolder,the conector has to be solid .You have an option and is using the aux,1 or 2 and coneting you vcr to either one those imputs then you will need to change the channels thru the vcr,this way you will not have to worry about the tuner.Let Us know how it goes or if you need more information.

Loud sound would be coming from defective color wheel that is mounted i light engine, next to lamp housing.

You should check your home wiring and grounding. Also be aware of anything that has recently been turned on when this happens. Anyone using a microvwave, cell phone, or other appliance that might be causing the interference.
