When switched on, only a horizontal line across the screen appears but there the sound is normal.
Don't leave the tv on you will burn a line into the screen because it's so intense.
You have whats known as "Frame Collapse" Have a tv tech sort it
SOURCE: TV has a thin horizontal line across the screen
intermintence in vertical IC deflection its a job for experienced tech need to look for that circuit and do fine job resolding that IC
SOURCE: Proscan PS35123-horizontal line only,sound ok
You have whats called a verticle swep falure. Its probably just the verticle output IC but if you dont know much about soldering or circuit troubleshooting ,you should leave this to the pros. Theres way to much Hi voltage inside these sets to twiddle around inside them. Also there are no consumer serviceable parts inside these sets as well, as they are all solid state, and my advice is spend a few bucks and get a pro to do this job for ya, as it can, and will, kill ya if your not careful.. Is it worth saving a few bucks??? Naawww Call a pro.. Good Luck
SOURCE: Black line running horizontally across TV screen
A line on an LCD, either horizontal or vertical usually means the video driver board is defective or the screen is defective, does it show up as black even on a dark screen? That means a line of LCD "shutter"s is not working and there is a problem that cant be fixed by a reboot or channel change. Bummer.
