which items are the easiest to replace the capacitors? i dont mean troublehooting; im not counting the repair of ther components (ie transistors) or anything else going wrong...

Re: Easiest to recap?
PSUs. They are hardest to damage the PCB onI love putting bad caps and flat batteries in fire and watching them explode!!
No wonder it doesn't work! You installed the jumper wires backwards

Definitely a Bestec power supply

Re: Easiest to recap?
Also set-top boxes/DVD players etc., especially if the power supply board is separate.My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.Comment

Re: Easiest to recap?
ive never seen a dvd player with bad caps. even thuough i did pop open a no-name generic junky one that didnt work and it did have crapxons but they didnt look bloated-but it wasnt worth trying to fix seeing that there plenty more better-quality working ones...Comment

Re: Easiest to recap?
i would have said PSU but some of the lower end ones have easy to burn off traces. add in cards tend to have less caps ... they do not have evil ground planes either.sigpic

Re: Easiest to recap?
wel computer PSU i agree is harder to mess up the pcb, but some of em are kinda hard to access or sometimes i have to remove like other componentes in order to reach the caps... as for computer mobos i've had certain issues with em hahaha i think some models/brands are a little hard to desolder specially... so my vote goes to other devices that might include some LCD

Re: Easiest to recap?
I'm going to go video / add-in cards here. PSU's, you have to fight the wires, heat up giant gobs of solder to desolder the old ones, battle glue, etc. Some PSU's go easy and some are a giant pain.
Video cards, you might have to remove the heatsink and run the soldering iron a bit hotter. There's no case to take apart, other than the computer case to remove the card. There are no wires to fight. There's no glue to hold things together or obscure the rating on the capacitor so you don't know what replacement to get. I think when you consider the whole job, the video / add in card is easier.A man convinced against his will is of the same opinion still.Comment

Re: Easiest to recap?
um-you basically mostly copied my post what i wrote, and you have ads in your signature. um m getting too suspicious of you being a sly scammer. but i think you put enough time and effort into making your account here you may not be.
if you are not don't be offended. welcome to badcaps forums!
if you are, go the fuck away

Here’s another motherboard that needed a full recap: an ASUS P5GC-MX.
This one was gifted to me some years ago by user Pentium 4, along with a few other goodies. It actually came in working order with no bulging or leaking caps. However, I noted there were United Chemicon KZG caps everywhere on the motherboard. The CPU VRM output (CPU V_core) was the only exception: it had only 2x KZG. The rest was 6x UCC TMV 4V 680 uF caps… which aren’t any good news either.
So here is what the motherboard looked like with its original caps:

Hi:
I am trying to repair this amplifier that I've bought as faulty. I've found some transistors damaged, the ones where I am drawing a red circle.
With the final transistors not yet installed (the expensive ones), I've started to measure some voltages:
Where I am supposed to have 1.12V (base Q524/Q523) I am reading -42V..................both channels don't seem ok.
Where I am supposed to have -1.12V (base Q526/Q525) I am reading -44V..................both channels don't seem ok.
I removed and tested Q514,Q516 & Q513,Q515 but the analyzer... -
I had a Sundown SFB-8000D amp come into the shop yesterday that wasn't giving any output. The guy who brought it in said he bought it off some crack head on Facebook marketplace for a good price, but bought it knowing it was broken. Apparently the original owner was cutting out the transistors to the right of the ones pictured whenever one would blow and take the output out. Best I can figure he also cut the legs on the S5 and S6 ic's as well and soldered them back together.
My problem is Sundown decided in the factory to remove the original markings on the IC's and now I can't figure... -
Welcome badcaps, repairing a Crosshair 15, in need of transistor specifics. Received a broken laptop that's was perfect for repair, threw away the looser transistors in a haste... Should and could have salvaged them.
In any case, I will be posting all my discoveries to this forum as a thanks in advance. Thanks in advance lol.
P.S. If anyone is familiar with such things, as in, If anyone knows that MSI uses one or one of a few types of transistors when marked with a number please let me know how I can find more specifics before I start throwing hail marys. -
I've been seeing a lot of cheap-looking (but not always so cheap) no-name AGP video cards on eBay for a while. They started popping up quite a bit when the market for AGP cards became more alive all of a sudden due to interest in “retro” PCs. One thing that struck me about these cheapo cards is that they almost always seem to come with garbage caps - including the abominable Sacon FZ. That aside, though, I've been wondering about the rest of the quality (or lack of?) on these cards. So I decided to satisfy my curiosity yet again.
This one was actually suggested to me by ChaosLegionnaire....
