p244w

[Phailak]

Hi,

Have an Acer p244w monitor that died, simply no power. Tried unplugging it, tried another outlet, nothing. I think I had a power surge that might of wiped it out so I opened it up.

What is identified as C603 and C604 seem to be badly damaged, white hard 'bloating' out of it. I'm a newbie at this stuff but this past summer I was able to change something similar on my salt system board for the pool, was wondering if I could do the same here (if indeed this is even the cause for the monitor not powering on)

I can't seem to find the part, I have the service manual for it I found online and it shows the diagram for the part, but also refers to it as C603 and C604

Included a pic, sorry if it's not great quality

Any help / guidance would be appreciated.

Thanks

EDIT: I guess I failed to upload the pic, trying to link it here:

Re: p244w

Where to begin....

1. Please do not post pictures inline. It really irritates retiredcaps and annoys others. Instead, use 'manage attachments' - below the text entry area.

2. The hard white 'bloating' stuff is glue, used during the assembly process. It's not the cause of the problem.

3. The photgraphic quality is more than adequate. The picture doesn't really help us.

4. I would like to see two more pictures - One from directly over the top of the power supply / inverter; the other from directly over the bottom of the power supply / inverter.

Re: p244w

Apologies... tried to edit it to remove the pic, can't seem to be able to do it, hopefully a mod can do so. I realize now it's because the pic was too big in width and height.

Sorry for my ignorance, but I have no idea where the power supply / inverter is. I took these from both sides top view. Maybe you can see where the ps and inverter is and I can take a closer pic.

Thanks, appreciate this.

Your photos ARE of the power supply AND inverter. In your case, the power supply and inverter are combined on a single board. "No power" is a little vague. Does the power light on the front panel come on at all? Do you get any type of flash of light on the screen when you push the on/off button? Any observations would be helpful.

A little more info on the symptoms.

Re: p244w

No nothing happens, no flash, no semblance of light, it's as if it's not plugged in. Like I said, at about the same time, I had my salt system board stop working as well and looking on line I saw that some people had the same symptoms related to a varistor (spelling?) that was burnt. It was easy to see on that board, there were burn marks, none here so it might just be a coincidence. I can't say it happened at the same time either, since I use the screen every day but only check on the pool a few times a week.

So no lights where there used to be (power button is lit usually as well as others) and screen remains completely dead.

I can try to get my neighbor to do some tests maybe, he did so for that salt system board.

As for other observations, don't really have any, it was working fine and just stopped one morning. No power, tried to unplug, replug, tried on another laptop, other outlets, those kind of tests and it remained 'dead'.

Re: p244w

1) Since you had a power surge, I'm assuming you've already verified you have power coming out of your wall outlets.

2) With power off and monitor unplugged, set your meter to resistance and check the main fuse F601 (next to C603 and C604) for continuity.

3) If the fuse checks good, set your meter to DC volts and try measuring the voltage across one (doesn't matter which one) of the large brown caps above F601. BE CAREFUL, since this is high voltage! Have your friend perform this test if you are not comfortable doing it.

4) If you get zero volts across the large cap, then checking the varistor, VAR1, would be a logical choice. However, I see the one on your board is missing. Did you remove it?

Re: p244w

OK will do, thank you appreciate it, should know more tomorrow.

I did not remove anything and I don't see any parts having fallen out when I opened it up so that is weird that it's missing...

The white 'stuff' between C603 and C604 is Glue, so ignore that.

VAR1 was never installed; it's a surge protector. You are thinking of the thermistor, which is just to the left and below BD601.
