Try changing source or input
SOURCE: TV screen goes blank but power stays on
Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.
Check if the remote is in TV position, that is, because most of the remote controllers have the feature that you can program them for use with another devices. Make shure that one button that says "TV" in pressed and released once before you try to change any function on the TV.
SOURCE: Prima HDTV has a black screen on TV, but works fine while Playing DVD
try turning the channel up or down with the tv remote to input 1 or 2 depending on which one is being used for the dvd player. tv should use input 1. dvd should be on input 2.
when turning the channel set it to show the dvd screen, then go up 1. if it doesn't show, return and go down 1.
SOURCE: Dynex 19Inch Vga no signal
You may need to set up the video card to see the TV so you can display the computer on it.Somewhere in the setting for your video card should be settings for that.
SOURCE: Dynex DX-LCD32-09. tv was working fine, then out
This type of failure could be in the LCD controller board or the power supply might not be providing enough voltage to the main board and LCD controller.
Let me know if you require further assistance locating the boards or part numbers.
