Acer AL2216W - Bad Caps!

[shovenose]

Of course. Stupid Acer Junk!

Some information: got it for free, from somebody who now wants it back because they think it's valuable. So I decided I should at least test it before I ask them if they're sure they want it back.
Well, it made a horrible squealing noise and didn't work.
This was going well for me
Told them it's a goner and I might try to fix.
Unfortunately I think that they are under the impression I'd be happy to give it back when it's working again.
Not really. I want this LCD to replace the 3rd monitor I'm using with my two Dell 22-inchers... an Apple LCD at 20" that is a piece of crap. At least this one is the right size and color, even if it's an Acer!
Iffy thing is, the person also gave me an almost brand new $500 Dell Color laser printer and an Intel iMac. Along with an iMac G5 with bad caps which is another story

Caps that need replacement:
-CapXon 220us 25V (3x)
-CapXon 2200uF 10V
-CapXon 1000uF 10V

Umm, so they gave it to you, but now want it back? Why did they give it to you in the first place?

I count at least 7 capacitors that would need to be replaced.

Don't think the capacitors that aren't swollen are good, they're also bad.

There should also be a small starter capacitors somewhere near the transformer, maybe under that white gunk ... 22-47 uF / 35-50v... something like this.
It's cheap enough to be worth replacing it at the same time.

If you're gonna order solder from digikey, order the caps at the same time and save on shipping costs.

A dreaded DAC- board but cannot read which one...good luck, hope its just the caps.

Re: Acer AL2216W - Bad Caps!

Bloated CapXon! They never fail! OP must have faked the picture. They are the most reliable caps in the world! [/TROLL]

Re: Acer AL2216W - Bad Caps!

lol...
I'm not replacing all of the CapXons because I'm lazy (and somebody gave me about 10 inches of solder they had lolololol so I can't waste any)...

I'm not ordering any parts. I have already picked replacement caps out of my cap bin

OK, let us know when it dies again; hope it lasts for you. These Acers seem to die a lot. My dad has the 19" version of this. Hasn't died.... yet.

Of course they die a lot they're Acer
I'll be sure to keep this thread updated!

Re: Acer AL2216W - Bad Caps!

Well, given that I couldn't find the rest of my solder and I also couldn't find my soldering iron the project had been suspended.
My friend bought me some solder from RadioShack - it's the best solder I ever used! (not kidding)...
Anyway, I replaced the big cap with a Rubycon and the other three with SamXon capacitors. I left the 10/1000 bulged as I didn't want to bother trying to unstick it from the white glue and I was too excited at the prospect of a third monitor to wait 10 more minutes.

Anyway... (sorry about the horrible tablet picture), IT WORKS!!!

Nobody seems to care?
alright, no problem, whatever.

That white glue is such a pain in the ass that any device with that glue on it is almost not worth repairing. However, you should have replaced that cap while you had the monitor open.

White rubbery glue is easy to cut off. The yellowish hard glue is the pain in the ass. It's almost indestructable and will begin to conduct electricity over time.

Care to share how I should remove that?

The white glue in my computer's power supply sticks back together after it is cut, leaving no sign that anyone ever tried to cut it. After it reseals, it is just as strong as glue that I didn't try to cut.

A blade.

Re: Acer AL2216W - Bad Caps!

It depends whether it's the hard white glue or the rubbery stuff. If it's the rubbery silicone stuff, then you can just cut it off, as th3_un1qu3 suggested. If it's the hard stuff (which I think it is on this monitor) you have to cut and pull it off with pliers. I don't usually worry too much, though, about white glue. It's only the hard brown stuff that gets conductive which I really try to remove.

No no no no no. NOOOOOO! Just clear the solder off the holes with some desoldering braid, grab some pliers and rip it off. I've done it heaps of times, and it won't hurt it
