Is it the television or antenna or both.
This is one for the electronic folks to ponder.
I have a 2010 TT with a Jensen 18 “ Television and a Winegard Sensar antenna of the same vintage. The problem is the tv will drop the signal.
If I am at home where the signals are strong and the tv’s signal strength bar is in the blue indicating a superior signal; the TV will periodically drop the signal and then re-sync, perhaps every minute or so. In a campground where the signal strength is weak to moderate the tv will drop out and re-sync several times a minute.
So far I have done the following,
• I have removed and taken the Winegard Sensar head apart to make sure the circuit board was not corroded or full of insect nests etc. It was remarkably clean for a unit that has been outside for 4 or 5 years. The plastic housing opens and snaps together very easy.
• I have tuned in a station and shut the amplifier power unit off to make sure it was sending power to the antenna amp.
• I have shut the amp power off; which bypasses to the external tv wire connection; usually a cable box hook up. This seems to have worked also.
• I have removed all the face plates and backs panel so I could check the antenna wire connections.
So far I have found nothing.
My next plan of action when I get home to a strong signal area is to,
• Measure the voltage to the antenna pre-amp.
• Unhook the Jensen tv and connect another tv to see if it also drops the signal.
• Hook up an antenna to the external antenna line to see if the tv still drops the signal.
Before I do all this I wondered if anyone on the board has had this type of trouble?
Things were easier in the pre-digital days; you either had picture, picture with snow, picture with more snow, or you had nothing at all. :W
