Hi all,
I have GA-K8NF-9-939 motherboard and had a FSP300-60PN(PF) that I replaced it with Antec TPN 750 blue PSU. I noticed a week ago a capacitor leakage on top of it, after a few days one more, today another one, the top of it is getting brown.
When I had first PSU, had no problem at all (was pushing more air down to the pc case too), since replace it, the capps started to fail one by one. There are 5 of NCC KZG 6.3V 3300UF
The system is working fine, no problems.
I have also replaced the cpu's cooler with Freezer 13. The fan is pushing the air from one to other side not down to the cpu like previous cooler. The Northbridge temps is over 60.
Since noticed the first capacitor brown on top of it and swollen, I left the side panel off, thinking that the heat could be a problem.
I have ordered some of Sanyo WG 6.3V 3300UF to replace all five capacitors.
I am thinking to send back the new PSU to get a different one.
Any advice is welcome.

This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
i've got a pretty rare motherboard that i'm evaluating for repair. it's a biostar m7mia-raid which is the only ddr socket a motherboard ever produced, consumer or industrial, with an isa slot. its 20 years old now and finally gave up the ghost last month. i was saving a dd image of the hdd to a portable usb drive when i found it unresponsive with a black screen and a solid lit hdd led. after forcing it to power down it never posted again. the psu/cpu/case fans will spin and the onboard motherboard power led will light up, but no beeps or error codes even with the cmos reset and ram plus all expansion... -
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... -
Hey there, retro fans.
I have an MS6163 version 1 board I'm trying to repair which was obviously used as a donor because it's missing a few parts, mostly capacitors. There are few high quality images online that would allow me to read the capacitor values (bad angle, blurry photos). I thiiiink I've figured out most of the values for the missing ones except for one in particular, number C210, which is in the bottom-left of the attached photo. Could someone with this board be so kind as to take a look at theirs and tell me the capacitance and voltage values of all the highlighted missing... -
Hi,
I have a Dell Latitude 5590 with motherboard LA-F411P Rev 1.0 that has liquid damage and doesn't turn on anymore when only the charger is plugged in. However, it does turn on when powering it from a battery. I couldn't find schematics for this exact board, but LA-F401P seems to be similar (that post says LA-F411P, but the attached schematics are actually for LA-F401P): https://www.badcaps.net/forum/troubl...oardview-neede...
