Re: Beware next generation Chinese fake Sanyo WG!
You mentioned profit, and so I'll assume that you're charging the owner for these repairs. If you're knowingly charging people to make junk repairs that only last a year, then that to me is deceitful....

Re: Beware next generation Chinese fake Sanyo WG!
Ah yes, I see now. The table was a bit confusing the way it was laid out, especially since the quantity was formatted for currency. Mind you, I don't think comparing KZG and KZJ against HZ and HN was a fair test; the real question is how long do you want the repair to last?...Leave a comment:

Re: Beware next generation Chinese fake Sanyo WG!
I'd hardly say there's a huge difference in the price, and if it costs 8 dollars more to get them from a reliable source and know you'll get genuine parts then it's worth it. If the caps you put in are just going to fail 2 years down the line, then what's the point of repairing it? To me that's not taking pride in your work....Leave a comment:

Re: How to remove leftover solder
If the copper of the through-hole joint goes through the entire board, then it's often easier to attack it from both sides. First fill the joint with leaded solder, apply some flux, try to get as much out as you can with solder wick, and then turn the board over and use the wick on the other side of the hole to pick up what's left.
This method usually works out pretty well for me.Leave a comment:

Re: Fried graphics card
You're right. I'm so used to the design of FZs that I didn't stop to take a closer look, especially as I know how popular they are in graphics cards. There are newer FZ capacitors that don't have any vent stamps on them. Also the two small green ones by the fan connector are Teapos, yes....Leave a comment:

Fried graphics card
I pulled this 8400GS from a dead Asus machine today, and I was quite surprised at what I found. This card has a Capxon capacitor, Teapo, KZG, and the cherry on the top is a single Sacon FZ. I've never seen so many bad brands on a single card.
Surprisingly the machine still works; it just needed a new power supply and a new graphics card.

Re: are these bad caps?
In my experience, it's typically Samxon capacitors that are the cause of Samsung monitors becoming defective. For example, here is a Samsung Synmaster 2220WM with bad Samxon caps on the power supply board:

Re: are these bad caps?
It looks like these are Samxon capacitors:

I don't know much about this particular line of capacitors, but Samxon in general tend to go bad. Samsung often use Samxon in their monitors which have a habit of developing problems.
The datasheet says that they are polymer capacitors, so maybe it's worth a try.Re: are these bad caps?<br /> <br /...ulr.html[/url]Leave a comment:

Re: Scary Trend of Rubycon MBZ failures - No bloating!!
I've pulled a load of 2200uf caps from Dell 745s; most of them were Rubycon capacitors dated '06 and '07. I decided to test them for the sake of curiosity and most of them were around 500uf. Many of them had vented or had some electrolyte crust, but some of them still appeared to be normal.Leave a comment:

Re: New more 'explosive' Sacon FZs
I hate Sacon FZ; the only thing you can rely on them to do is explode. I had a graphics card with these on them that blew up when I was watching a full-screen 1080p video -- it kind of startled me when there were two loud pops. It was a lesson learned.Leave a comment:

Re: New Members - please post your introductions here
Hello all,
My name is Guy and I'm from England. I'm a electronics hobbyist and I'm also a professional hardware support technician -- a position which I've held for almost a year. I care about quality in everything that I do, and designing and building electronics is no exception.
I've met a lot of bad capacitors throughout my life, and my job is no exception to that. I've had the misfortune of having to repair some Dell Optiplex 745s that constantly have the same 5 bad capacitors over and over. I mostly...Leave a comment:
