Acer v193w

[newton]

Good day to all forum,
I would need the service manual of this monitor ACER V193W.
The problem with this monitor is as follows:
lights for a few seconds, you see the logo and just after the lights go out.
Can someone tell me how do I remove the back cover (I do not think there are screws).
Thanks!

My Acer v193w has a different problem

Just got one myself. It displayed typical behavior in terms of power. I got the "Cable Not Connected" message and the "No Signal" messages when I turned it on and plugged in the video cable. I was not able to get a video image, so I focused on the video board.

All are Su'scon caps. Three of them at 10 uF and 25V tested around 9 uF and 4.1 - 4.5 Ohms on my ESR Micro 3.1 and all capacitors were tested in-circuit.

The capacitor opposite the VGA port and the one near the center feature 150 uF and 10V and tested around 93 uF and 0.30 - 0.45 Ohms.

I'm worried about the one on the opposite corner from the VGA port. It features 100 uF and either 10 or 16 Volts. When I apply my ESR Micro 3.1 needle probes, the meter freezes (it was set to cycle between displaying capacitance and displaying ESR). I have to remove at least one probe to get my meter to cycle again. While I get ESR around 0 Ohms, capacitance is anywhere from 1000 Ohms to (X times 10^4) Ohms.

I'm planning to start with this wacky capacitor, but I'm also wondering if I should work on the other five.

I can't figure out the best way to remove the power board, either.

Hello,
after a long time I resumed work this monitor.
The problema is solved by changing one of the four lamps that I found dead.
Thanks to everyone for the help.

I have exactly the same situation, can you elaborate which four lamps you replace. Thanks in advance.

One of the four CCFL lamps, there are 2 for the top, 2 for the bottom.
It can be burnt out wires, worn out lamp (blackened ends).

You can make 2 test lamps to find out if you have inverter problem or bad lamp.
