Question about Clarion Car Audio & Video
My motorhome has a vma 7194 monitor located on the back of the seat and cannot turn it off. The screen only displays vertical lines in various colors, especially green. How can I turn it off. I press the power button on the monitor and will not turn off. I am afraid if it stays on, it could heat enough to start a fire.

sounds like a graphics card failing
is it on board graphics ?
if so try a graphics card in there see if that helps it
also if you could borrow a monitor and see if that helps
its either one or the other and is a process of elimination

Your panels are dying.
Well more to the point the driver tabs that run the panel are dying and are not going to be cheap to repair for either case.
For the stand alone LCD, it is cheaper to get another one.
For the laptop, find a laptop on Ebay or similar with a dead motherboard and swap out the screens, also gives you spare parts for the laptop. If you goto a repair shop and get a screen it will cost you as much as a new laptop.

Vertical IC loose connection. Best is to reflux it or resolder. It is in internal circuitry inside the monitor commonly an upside single line IC.
And its a minor repair only. But I recommend it to be serviced by a qualified technician. Inside it are plenty of nasty voltages. It might caught you.

The Problem may be due to the defective inverter unit inside the monitor. Dry to resolder if any dry joint on the inverter PCB or replace the inverter board.

Have you tried to connect your laptop to external monitor?
If you get normal picture on external monitor, then you need to replace LCD screen, but if you get same picture on external screen, then unfortunately you will need new motherboard, because graphics card is integrated to motherboard.
