I recently recapped a 15" Kristel LP LCD that was used in an arcade game.
It was flickering as if the backlight was going bad, but I opened it up and found several bulging Teapo caps on the main PCB. I replaced them, only to find that it still flickered.
I took it back out and went over it with my ESR meter and found that all 27 caps on the board, from the larger 1000uf caps to the miniature 22uf caps were all bad, most of them being totally open. After a complete recap with some UCC KY series caps, it is working like new again. Every cap on the board was Teapo.
Anyone else ever run across LCD monitors that have toasted caps? This thing was only a year or two old.
I prefer to stick to Samsung LCD's, but I've got my eye on a Sceptre 20.1" that has a 1000:1 contrast ratio. Since it only costs ~$230, the odds are probably pretty good that It will have crap caps too.
