I looked through old emails and I found a Digikey receipt for the capacitors for the logic board, so it looks like I replaced all of them with Rubycons back in 2017. I'm pretty sure I've never touched the power board but I wouldn't figure that could cause flickering just in specific color gradients. That sounds more like it would be an issue with the logic board. Maybe it's something else on the board. -
Fixing an I-Inc IF281D for the 3rd time, now with added flickering!
Hello everybody! It's been nine years and I'm back again with the same monitor that several people here helped me fix back then. The first time, I replaced two caps as was recommended here and the original problem was solved. Then it started acting up a few years later and I came back for a parts list and replaced a few more caps (I didn't make a post about that and don't remember which ones), and again the problem was solved. This time, however, I'm not sure if it's caps.
The monitor stays on but certain colors will flicker. Generally it's darker colors like dark greys or dark blues,... -
Dell Latitude E6540 - 2nd dead motherboard
Greetings and sanitations! Several years ago I received some really awesome help on this forum for fixing my monitor (which is still working) so I figure maybe someone can help with this laptop issue.
I have a Dell E6540, motherboard 9411P, DP/N:VWNW8. A year ago it died a strange death where at first it wouldn't turn on all the time, but would turn on when it felt like it, then it got worse where it wouldn't turn on at all and I would just get a flashing light. So I replaced the motherboard with a matching part number board. (I still have the old motherboard) Now a year later this... -
Samsung JU6500 Problems
I've got a Samsung JU6500, 55" TV with a display issue. You guys were super helpful with fixing my monitor, so I thought I'd ask about this TV.
It turns on but there are vertical lines all over the screen. At first, one side is black and one side is white, both full of lines. Then when you plug a source into it, the pattern of lines changes, but you can never see an image.
I've looked around and I can't find any information about issues with this TV, except a few people on Amazon complained that they flat out died on them. There seem to be three boards inside,... -
Re: Fixing an I-Inc IF281D (caps) on the super cheap
I'm back again, this time with my friends' monitor. It's the one I mentioned above that's identical to mine. I replaced all of the caps about six or eight months ago and it's been working since then. If I remember correctly, the function buttons were finicky but the power button worked fine. Until last week. Now the power button doesn't do anything and the monitor doesn't turn on. No light, no "check signal", no anything. When I plug the power cord into it I can hear a very faint "donk" or click noise.

Re: Fixing an I-Inc IF281D (caps) on the super cheap
Wow, thanks! That's good news since not only do I not use the monitors' speakers, they're not even plugged in internally. When I first got the monitor there was a light buzzing sound from one of them so I didn't plug them back in when I put everything back together....Leave a comment:

Re: Fixing an I-Inc IF281D (caps) on the super cheap
Not sure how this board feels about necroing an old thread, but I thought I'd give an update.
It's been almost exactly two years since I replaced those two caps on my monitor. It's been working well all this time up until a few months ago when I started noticing artifacts in solid bright green colors. Then maybe six weeks ago it started having trouble turning on, flashing on and off several times before it settled down and stayed on. I figured it was time to replace the other caps.
I bought Rubycon...Leave a comment:

Re: Fixing an I-Inc IF281D (caps) on the super cheap
If any of the professors would like to grade my first (and cheap ass) cap replacement, here's two pictures. Pretty sure I don't need to point out which ones are factory and which ones aren't....Leave a comment:

Re: Fixing an I-Inc IF281D (caps) on the super cheap
I'm probably going to get a rap on the knuckles for this, but when I was looking for an old board or card to practice desoldering on, I found several old parts which still work and happen to have 16v 100uf caps on them. One is an old ATI Rage pro AGP card from around 2001. ATI used to build really solid cards. I just threw out an ATI all-in-wonder pro PCI video card from 1996 that still worked when it went into the garbage can. So... I desoldered two caps from the ATI Rage and put them into the I-INC where Lumberjack suggested,...Leave a comment:

Re: Fixing an I-Inc IF281D (caps) on the super cheap
I have a 30W soldering iron and lots of patience. I have flux, but I'm not sure how/where to use it. I've never needed it with this rosin core solder. I can get some desoldering wick if absolutely necessary, but there's not much solder on these old caps. I read about how to clear the holes before installing the new caps and I'm confident I can do it correctly. Going to practice on some junk boards this week.
What things do I have to be careful of to avoid ruining the board?Leave a comment:

Re: Fixing an I-Inc IF281D (caps) on the super cheap
Thanks a lot for the replies. I was getting concerned about whether I should be directing my attention at the logic board or a different board, and you guys have settled that pretty solidly. The logic board it is.
I actually managed to locate a soldering iron for stupid cheap, so that frees up just enough cash to get all the caps for the logic board from Digikey. W00t!
Lumberjack, that is indeed my board. It's good to know that I can likely fix it with just two caps. I will definitely start with those...Leave a comment:

Re: Fixing an I-Inc IF281D (caps) on the super cheap
Even on eBay the good brands of caps are out of my price range. The best I can find on eBay are the ones I listed above. The only place that sells caps around here is Radio Shack and they charge $1.50 apiece. I thought I had found a cheaper place at Newark.com but their shipping charges are insane. It looks like Digikey.com or Mouser.com are the cheapest for quality brands of caps, though they're still slightly out of the range I'm working with.
After toying with the monitor a little more, I found that when the...Leave a comment:

Fixing an I-Inc IF281D (caps) on the super cheap
Greetings Peoples!
I'm new to this forum, but not new to forums in general, or to electronics. I have a long history of fixing PCs, though this will be my first attempt at replacing caps on a PCB. So right to the issue:
First I'll start out stating that I'm broke. Like my wallet is so empty the dust mites in it are going "WTF man, seriously?"
Yesterday I got an I-Inc IF281D 28" LCD monitor in exchange for some work I did. I knew going in that these screens often have issues with bad caps, but there's no dead pixels an only one small... -
Re: New Members - please post your introductions here
Greetings and Sanitations! Just picked up a 28 inch monitor with, guess what? Bad caps! Or at least I think it's bad caps. These screens are known for that problem and it matches the symptoms posted by others with the same screen.
I'm on a ridiculously tight budget, so instead of buying a pre-assembled kit with all of the caps in one handy package, I'm going to try to source the needed caps individually by size. For that, I'll probably need a bit of assistance from some of the crazy smart people I've seen in this...Leave a comment:
