Re: Why are crap caps still in use???

No you can't bring a screwdriver to split them open, but you can be a voice for others. Look out for the weaker of the herd or we'll just get lesser products as a whole. The wolves do not dictate product satisfaction.

But this is a small section of the interwebs that knows more than the average bear. I don't know the brands you mentioned. Maybe because they're set to fail on a world market.

Re: Why are crap caps still in use???

Let the customer suck up the cost then. Had this in my own thread, but it wasn't fit for my own topic. I fixed 16 Samsung 204B's a while back and am tackling 24 225BW's and two more 204B's sitting in our graveyard:

Going with the BadCaps question of "why is this still happening?", it's hard to really figure out why this happens. Like iPhones, I guess the upgrade cycle shortens and most aren't expected to keep LCD's very long so it's "Good enough" and get's them through the warranty period.

Re: Samsung LCD PS - Change 150μF/450V?

Perfect link, thanks! I did search but not well enough obviously.

I never went so far as figure out what exactly they do in the circuit. These big caps are in a section of the PS that appear to be in the line voltage side (60Hz/120VAC here), do seem to be filters, and did see prices in the ballpark you've noted. That last part is what got me as it will double the cost to repair them all and decided to ask if you'd even bother. Peace of mind is always helpful and I very much appreciate it!

I feel comfortable...

Re: help can't find replacement caps!!!!

A DMM with a cap setting gives funky readings back on a bad cap. My Fluke 189 shows a random bad 820μF as being 34.6μF and 330μF as being 67.1uF. All different readings as I dig through the bad-bin and doesn't give a good value unless it's actually a good unit. If these are known to be bad units, I'm afraid a DMM isn't going to help much.

I'm good w/ Photobucket too since 2002. Maybe something's changed and I'm just grandfathered in or something? That's another topic entirely.

Hey, new to posting but have been lurking for years. Now I have a subjective question for ya'll.

About 8 years back I picked up a bunch of plagued Samsung 204B LCD's from work. It's just as much trouble to dispose of them so I decided to repair them instead. They all seemed to have the same bad condensers on each and everyone of them (CapXon 680μF &330μF / 25V) which I replaced. I didn't have an ESR meter back then to test the big one so I just replaced the obvious bad ones With Ruby's and all worked for a very long time (donated them and no complaints).
