Hi.
I have one problem with my monitor (Philips).
One video with problem:
The monitor has fault with and without input signal.
The problem is not immediate, it happens after being turned on for a few minutes.
The power supply is discarded, it is external (19v 2.3A) and I have replaced it with other.
I have replaced the large 47uF 100V electrolytic capacitor, but the same is still happening.
