Default Hanns-g HL248

Hi guys, have a HL248 that was going black or I'm thinking scramble lines sometimes. Sometimes it would work fine but seemed like code on a page would make it fail. Other times straight to black. It's been in storage a while and pulled the boards before trying again so going off memory.
I've heard of a successful fix on this monitor just replacing the caps. My problem is I'm trying to figure out the best caps to put in it that will fit. None of mine look bad. Has anyone had similar problems and fixed one of these yet?

The board with a single cap has a low impedance FOAI FZD 47uf 63v.
Data sheet www.chinafoai.com/ep24.htm

Easy enough and looks like digikey has panasonic FC or nichicon UPW that would work. Which would you recommend?

The other board has 3x FOAI CD11XH 220uf 16v and 3x FOAI CD11XH 100uf 16v.
Data sheet http://www.paullinebarger.net/DS/Foa...H%20Series.pdf

Now this one has a height restriction of 9mm but up to 10.5mm may be able to fit with some finessing.

The only options I'm seeing are URZ and ML for the 220uf and GA, URZ and UTT caps for the 100uf. Which would you recommend?

most of the time I use Panasonic, Nichicon or Rubycon. Never had any trouble with these brands. Nothing had come back that I've repaired using these brands.

How about on the smaller ones where only UTT and ML for the 220uf and ML, URZ ,MH7 and UTT caps for the 100uf are available? These are the ones I've not used. I also notice 1-4 impedance available with the UTT being 4 and others not showing.

The other board has 3x FOAI CD11XH 220uf 16v and 3x FOAI CD11XH 100uf 16v.
Can you please mark the location of those caps?

The 220uf are the 8mm diameter and have the tri score top and the 100uf are the 6.5mm. I can mark them and upload a pic of the back side of the board if it helps. It has pin out markings also so good for getting a documented fix if it works.

Why not just install the caps leaning on their sides then. That should allow you to use just about any low-ESR cap, possibly up to 8 mm diameter (since you have 9 mm of height of the old cap).

Between Panasonic FC and Nichicon PW... I have no preference really. Both are excellent and I've never had failure from either.

The board with the dvi/vga gets clam shelled in a metal cover.

The FC/PW is only available for the 1 cap that is on it's side. The other 6 I'm unfamiliar with the series available. The impedance seems like it might be important also.

On the plus side I have a new camera DVR with known crap caps that I want to replace also. Just have to figure out what series of the brand they are. Feel better about paying more in shipping than the order cost if I can kill 2 birds with one stone.
