The dissasembling part was very tricky. It required a lot of patience. Be very gentle with the plastic frame and do not bend it too much or it will break.

ACER V193HQ LCD MONITOR DOES NOT TURN ON
ACER V193HQ LCD MONITOR DOES NOT TURN ON
Recently a friend of mine had a problem with a Monitor Acer V193HQ which didn't want to switch on. The power light kept
blinking amber.
I found the Service manual here.
I could go on and on about the procedure to find the problem but I will leave that to you.
The dissasembling part was very tricky. It required a lot of patience. Be very gentle with the plastic frame and do not bend it too much or it will break.
The problem was a faulty SMD resistor (2,7M) with a much lower value (500k) than it should've been which I replaced with an axial 1/8w resistor. Then a couple of capacitor filters, C818 220uF/25V and C822 470uF/16v where bad (bulged). If you have a look to the schematics the cap's have different values in particular C818 it apears to be 35V and it was 25V in the board. I replaced them with HT/105ºC type of cap's and with what I had at home, 100uF/35V and 1000uF/16V.
After this components were replaced and the monitor put back together, it worked perfectly well.
