It's a brand. I believe they are owned by Daewoo or partnered with them: http://www.megastar.com/products/daewoo/Comment

Re: Need advice on recently recapped capacitors
hi ...i'm back
my board is working fine now but now my friend who has a similar board and problem is asking me to fix his old board too. HIs board model is similar to mine just its M2N68 AM SE2 (Mine was M2N68 AM PLUS)
What i noticed was that his caps were all the famous KZG series 15 in total of 820uf 6.3 v ones. i desoldered them all of the board and found that all caps look fine but were actually leaked from the bottom.
the other caps on the board were 2 1500uf 6.3v caps near eatxpwr connection (the caps has a (M) logo i.e. 105 c FJ (M)) and 1 330uf 6.3 blu cap with same m logo and a 470uf 16v M logo cap. and finally 7 small thin caps of 100uf 16v with same logo(i.e. (M).
No should i replace all the caps or just the KZG cause i dont know what the M is for. Also the board has the same symptom as my board had (cpu spins up but no display). looks like i'll be battling the same problem again..
Any help much appreciated.....
Also,
I have YEC , 1000uF , 10 Volt caps can i use these as a replacement for the KZG 820uf 6.3v. its esr is 0.08 at 20% tolerence.Last edited by firstview; 06-19-2013, 05:52 AM.Comment

Re: Need advice on recently recapped capacitors
those caps with the M logo in a square should be panasonic caps. the M logo stands for matsushita, the parent company (conglomerate) that owns panasonic. panny electrolyte caps are some of the best in the world and its highly unlikely that they are bad.Comment

Hi everyone, I recently acquired an HP EliteBook 840 G4 (6050A2854301-MB-A01) that I'm hoping to bring back to life. I'm fairly new to laptop repairs but eager to learn and willing to put in the effort to understand and fix this. Any advice or guidance would mean a lot!
What Happened
The issue started when the laptop was accidentally plugged in with reverse polarity. Before this incident, the laptop would show a power/charging light whenever it was plugged in. However, now it's completely unresponsive—no lights, no power, nothing. I've been doing some research and understand... -
I am attempting to repair a Dell Latitude E6440 laptop that was damaged when an end user shoved something into a USB port so hard that it destroyed the port and sheared off a surface mounted capacitor located behind the USB port; effectively preventing the laptop from powering up.
The capacitor is round approx. 5mm diameter by 5mm height with a plastic 'foot' and two small soldered pads visible (can't recall the specs printed on the top).
In order to repair it, I'm thinking of replacing the capacitor by transplanting a similarly marked capacitor from a donor board taken from... -
I've just been repairing some (very) old speakers with a loud hum that occurred as soon as you powered them on regardless if any actual audio is played through them. I work in a School so it's 99% likey that the Teachers have hardly ever turned the power off on them for well over 10+ years.
As you can see the top large capacitor on the right has a bulge on the top so defincately needs replacing. As the one next to it is exactly the same capacity and voltage I planned to replace them both.
What is your advice/opinion on whether or not on old(er)... -
I had my Quadra 840AV (which I recapped and had working) plugged in for some time without using it and randomly decided to turn it on today. Unfortunately it did not turn on. After checking the PSU, I found out I was not getting anything from 12V, only from the 5V rail. After a few minutes, I removed the PSU and plugged it back in the electrical outlet and it suddenly started making a weird sound and soon after smoke started coming out. I quickly unplugged it. I opened it up but on first instance I didn't see anything out of the ordinary really. I later turned it back on and one of the MOVs blew...12-22-2024, 05:07 AM -
Hi, I have some 32 bits computer motherboards that need repair, as they fail to
power on.
Here are some examples :
(N.B. "capacitors" indicated here are electrolytic capacitors located in the onboard
switching supply area).
(N.B. #2 : I could not find a 3300 microF aluminum-polymer with a higher voltage
than 6.3 V.)
1 - Motherboard #1 : this is an Asrock K7VT2 (socket A) that still works well. To put it on test
I replaced capacitors with aluminum-polymer.
3300 microF/6.3 V. x 4 replaced by 3300 microF/6.3 V. (KYOCERA...
