Question about ViewSonic NextVision N2010 20 in. LCD Television
Channels changes continuesly. from channel 2 to 60 in less than 20 seconds or so, very fast. I thought remote button is stuck but I removed the batteries from the remote and operated the TV manually with the same problem.
I can change the source to DVD and play DVD movies with no problem. Only when I am in the TV mode, channel changes automatically. Sometimes it stops at a certain channel randomly for few seconds to minutes and does the same.
There are a few things that can cause this. #1 most often cause is either something spilled on the channel button or something wrong with the bezel where the buttons are located causing the button to be pressed all the time. Check the buttons on the tv and make sure none of them are stuck. #2 is a bad button (switch). Replace the switch or the control board. #3 is a short on the wiring harness going from the switch to the mian board. Maybe it's squished against the frame somewhere. #4 would be a bad main board. You will likely have to take this unit to a service centre to have it looked at.
