Hi I have a touch screen monitor. It work fine for many years, but now It shows its age!
When I turn on the monitor, white lines appear on the display. They jump for a few seconds and then the display goes off.
Can you give me some pointers on where to start with the diagnostics.
There was a trail of dried light brown liquid on the board that the display connects to, as if a capacitor had leaked, but I couldn't find one. I cleaned the circuit board and resoldered the legs where this liquid was, but to no avail.
