Facing TV Problems? Ask a TV Technician.
Hello, my name is ***** ***** I'll assist you. I'm sorry you're having trouble with it. I need additional info to troubleshoot the issue.
- Does screen glow/ show back light or any graphics such as volume or menu appears?
- What video devices/ sources (such as cable box DVD player etc) are connected to TV and does the problem occur on all video input sources?Thanks.
OK, does backlight stay On as long as TV is On?
I'm working on it, please hold your replies.
Please make sure the main board jack is connected to power board securely and tight.
Did you get identical main board, t-con board and power board having same part numbers as of old ones?
This is bit odd issue in TV, since backlight stays On that means power board is fine so when you turn On the TV, does Samsung logo screen appear?
OK, since backlight stays On that means t-con board might not be getting video data from main board because of defective/ misaligned/ broken LVDS cable. Have you checked the LVDS cable is plugged securely and tight on both boards?
We can continue it later in your convenient time.
Can you try another LVDS cable, if possible/ available?
Check following supplier link to get replacement LVDS cable..
and if problem persist then I'm afraid it would be display panel failure because all have been replaced in TV and last thing is the screen which is suspected, replacement of display panel would cost approx new TV price of same size if still available with Samsung Prats in area. I trust my input will help you out.
