This is what they call LOW ESR. It's from Abit KT7A - some of them were bulged but this one has no signs and worst ESR of all.

Re: Jackcon LOW ESR
It's those caps that fail in no visible manner that are the nasty, sneaky bad caps - those that may make someone suspect a non-repairable problem and throw away the board for dead...Originally posted by RainbowThis is what they call LOW ESR.

Re: Jackcon LOW ESR
I have spoken to the designer of the ESR meter because it is not capable of reading the ultra low ESR of say the Samxon GC series or better. I have suggested some instrument design changes but I do not think the product will change.Gigabyte EP45-DS3L Ultra Reliable (Power saver)

Hi all
Hope this is in the correct place.
I'm planning on recapping both motherboards. I actually already ordered recplament caps for them, where I will be changing out most for poly's.
Could use some double checking to see if I'm not doing something stupid
.
Pictures of the boards are attached.
What I will be replacing with what : (planned)

got this tv from a friend who got a new one and didnt want to bother repairing this one.
he said it sometimes would just flash color patterns.
and sometimes it would just work
i figured it had some intermittent mainboard issue.
i stored it at home for a while before looking at it
when i plugged it in for the first time, i heard some popping noises
and then a big cloud of white smoke came out of the back of the tv!
i noticed the smoke didnt actually smell like anything. not like when an IC blows.
i unplugged it and took the back off and discovered... -
Greetings,
I have an Abit BE6-II motherboard that posts sporadically with the bare minimum components installed - CPU, RAM, PSU, and a Keyboard. I know it posts when the speaker beeps. Re-seating the components has no effect.
I thought the sporadic posting might be capacitor related. Upon inspection, non of the caps are bulged or leaking and they are all original. So, I pulled them ALL. While the ESR is OK, over half of them are leaking current between 1 and 2 mA. The biggest offenders are way out of spec, like a 1500uf / 6.3V measuring 2600uF and many of the 820uF caps... -
