Building an arcade cabinet, so needed a 4:3 LCD which (in my area) is hard to find. Occasionally a Samsung 204B shows up, but often with capacitor issues, but for the lack of options, I decided to grab one to fix myself.
Powers on, takes a long time for the screen to finally show up, and kinda dim.
I was going to buy a kit off eBay, but wanted to make sure I was getting good parts and the 100uf425v capacitor that the kits don't have. I figure, if replacing the others, may as well replace it as well.
Using www.digikey.ca (Canada) and I've done my best to match the uf, voltage rating, used my caliper to measure the height/diameter and lead spacing and tried to match them as close as possible as well. I searched for Nichicon because read that they were very good quality, and sorted by lifetime@temp assuming the more hours the better.
Ripple current/impedance however... I have no idea about. The old ones don't show that info (I didn't see) and no idea if higher/lower is better.
I was hoping someone with some know-how might be able to look at what I planned to buy and see if would work or if the wrong ones? I know this is a very common issue, so, probably a few people here have dealt with it before.

Again, info I had at hand I tried to match, but ripple current/impedance... I have 0 clue.
Thanks
EDIT - Went back to the site, made a spreadsheet for each capacitor, narrowing down the list by size and manufacturer (Nichicon, Panasonic, Rubycon, United Chemi-con) capacitance, voltage, stock etc.... physically, I believe these will fit, and the basic capacitance/voltage is a match... just not sure about the other specs.
