Re: ECS mcp61pm-hm 6-bad 1800uf 63 Tk caps

Just goes to show that the Japanese can make junk caps too. I have an aced at work from a customer. It has an entirely different board to this. Caps are a mixed bag of TK and sanyo. The TKs are bulging, but the others look fine.

EDIT: I always add fans to the chipsets on these boards too. Being nvidia chipsets, they need to be kept as cool as possible.

i have 3 of these in the recap pile waiting for me.
came to the conclusion that the tk caps are junk.
these were used in a industrial unit with an ac hanging on the cabinet.still blew up.in about 2 years too.

I know digging up posts is a bad thing, but I wanted to give a thanks for badcaps and this thread. I picked up a dead hp pavilion for free and found out this guy had the EXACT same caps go as the one I found! Must be one really big bad batch of caps. The time this board would have died is similiar to the OP.

Now I need to keep my eyes out for more easy fixes.

Well, success! I've purchased replacement caps from this website.

Good job. Thanks for supporting this site with your purchase.

Well, success! I've purchased replacement caps from this website.
All went okay. A little difficulty in clearing the holes of solder after removing the bad caps.
I ended up using a 0.65mm drill bit to do the job.

My HP Pavilion a6357c is back to life! Prime95 now runs stable.
Thanks BadCaps.net!

After removing my MCP61SM-GM motherboard I found the 5 bad caps are the same 6.3v 1800uf caps as in the first post. So I figure I'll just get 9 and replace all of them to be sure. I'll have to post some pics later of my progress.

Re: ECS mcp61pm-hm 6-bad 1800uf 63 Tk caps

Where can I get the replacement caps? I just ran into a friends' computer with 5 bad ones, an HP Pavilion a6357c with a MCP61PM-HM (Nettle2) motherboard. I haven't yet taken it apart to see which values they are, but they all seem to be the same type, like the row near the CPU.

I was trying to find a replacement board, but they're hard to find. A different board that may fit could be around 60-130$. I've recapped an ECS board many year ago, so it shouldn't be too difficult.

Does anyone know if the badcaps store MCP61SM-GM kit would work the same?

Re: ECS mcp61pm-hm 6-bad 1800uf 63 Tk caps

i have done a bunch of these.used 330@16 sanyo sep in vrm input.
820@2.5 fujitsu re on output.
same on vdimm and vtt.

Re: ECS mcp61pm-hm 6-bad 1800uf 63 Tk caps

Looks like it will be fine now. It ran without incident for:
24 hrs Memtest
24 hrs Prime95 Blend Test
24 hrs Prime95 In-Place FFT Test
24 hrs Prime95 Small FFT Test

Here's a picture of it with all those polys.

Re: ECS mcp61pm-hm 6-bad 1800uf 63 Tk caps

I've recapped mine. I ended up going with Panny FJ for the non-VRM 1800uF caps (a bit cheaper). It's been running in memtest all night now (15 Hours, 54 minutes and 38 seconds to be precise). 34 passes and still no problems yet.

Re: ECS mcp61pm-hm 6-bad 1800uf 63 Tk caps

I got fedup with mine sitting in the corner and randomly decided to order some polymers. I replaced every one of the 1800uf Tk's with (they are LG and either 820 or 1000uf) but I've not tested stability yet, I probably will sometime this week though and I'll let ya'll know.

Re: ECS mcp61pm-hm 6-bad 1800uf 63 Tk caps

Same board, same caps, same problem. 3 TKs are bulged. Two near the PCI-E slot and one between the RAM slots and CPU socket.

This board has already been given a partial recap. I replaced the 3 1800uF 16V TK caps with 1500uF Ruby MBZ and the 1000uF OST RLS caps with Sanyo WG.

I've ordered more caps to replace the rest. The 470uF 16v caps (currently G-Luxon) will be replaced with MBZ. The 4 1800uF caps on the VRM out will be replaced with 820uF Nichicon LF Polys (like the other polys on it) and the other 1800uF caps will be replaced with MCZ.

Re: ECS mcp61pm-hm 6-bad 1800uf 63 Tk caps

if the caps are bulging up in the center, then most likely they are bad. one other thing to check, make sure that all your fans are working and nothing is clogged up of blocking air from getting through. If any parts are overheating, it can cause the same problem.

Re: ECS mcp61pm-hm 6-bad 1800uf 63 Tk caps

I've seen bad TK caps as well on an ECS board. I consider them as a bad brand, Just like Chemi-con KZG and Nichicon HM and HM. Just because a cap came from japan doesn't mean it will be reliable.

Re: ECS mcp61pm-hm 6-bad 1800uf 63 Tk caps

This is a year later but just wanted to let everyone know I am experiencing the same problem with these capacitors. I would experience freezups and restarts and bsods in vista and w7. Sometimes scans would go for hours of memory or backups but other times i would freeze every 2 minutes. Tried everything I could think of software wise and even swappin out parts PS graphics HD.. and did notice these caps bulkin at top, no leaks but very frustrating problem. We mustve got a bad batch.

Re: ECS mcp61pm-hm 6-bad 1800uf 63 Tk caps

Hmmmm. Except that this value isn't listed. Likely a "special". Maybe made by OST for TK or vice versa?

I'll go with the heat related. The ratings per the datasheet are very good.

Re: ECS mcp61pm-hm 6-bad 1800uf 63 Tk caps

TK is simply distributed by OST. TK is a japanese company, and is typically reliable.

This may be heat related, not correct series for this situation, or a manufacturing defect.

Re: ECS mcp61pm-hm 6-bad 1800uf 63 Tk caps

Wow, why does capacitor web have TK listed as a good brand?
