I hate to give you bad news but I believe this will be a panel issue and it's not going to be fixable. You can try a different tcon board but I don't think it will help
This could be the TCON board. IT could also be cable connections and the edge connection on the LCD. It is not going to be cheap to fix. If you post the model number if would help.
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
maybe your TV have a deffective LCD PANEL,cause those are the systoms of the deffective lcd panel..better to put your unit the nearest service cnter or well trained technician to do the job,,goodluck
Uh-Oh....Vertical lines, NO PICTURE. That is NOT good.
Did your TV get hit or fall over?
The LCD panel is actually broken.
If
you had a picture on it, it would still be a bad LCD panel, but when
you get lines and no picture, it means the row/column bus has been
severed somewhere.
The downside is the LCD panel will cost the same or more than the TV set.
the problem may be a combination of three things, it may be the lcd panel, the main printed circuit board, or the logic printed circuit board, the small circuit board that the panel plugs into sometimes. replace either one at a time or all, these situations always come with some trial and repeat testing. Good luck.
Inside the monitor.
I don't know how comfortable, or knowledgeable you are about monitor repairs, but your next step would be to open the monitor, and reconnect any wired connections within.
Make sure to take safety precautions any time you work on the internals of a monitor.
If the monitor is still under warranty, contact them aboout a repair, or replacement.
If it's not, it's time to "go under the hood".
With the cost of LCD montiors as low as they are now, it may not be cost effective to attempt a repair beyond checking internal connections.
