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 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...

Hello everyone !

I am new to this forum and also a begginer/hobbyist in electronics. I have a question about an old AT motherboard model PCChips/Hsin Tech M537 V3.1. It hasnt been powered on for 30 or so years.
I have read that it is not safe to power it on after such a long time because capacitors can suddenly burst. When I inspect capacitors I cant notice any visible damage,leak,corrosion or bulged capacitors.
What are your suggestions ? Replace all capacitors maybe or ?
Thank you in advance for your answers !

hey all, iv got my favourite battery charger here which iv had for many years probably 15 years now or maybe even more. it still works good but thought id open it up to clean the dust out of it, lots of dust inside but now its clean and noticed 4 capacitors inside it and wondered if i should replace them.
it has inside:
2 x 47uf 16v caps 105c branded as Su'scon (lol sounds sus to me)
2 x 470uf 16v LZ105c branded as G.Luxon

not heard of these brands are they any good?

iv attached photos of the charger and the board inside for an idea on the type of...

Hello,
I need help to find the value of 2 missing capacitors ( C102 and C117) on my Easun SMH-II mainboard (solar hybrid inverter). I circled it in red on the close-up picture. The 2 old capacitors are completely missing, so I have no reference. Does anyone have this board and can tell me the value or make an educated guess based on the location ?


My model is : EASUN SMH-II 7 KW
Mother Board : P/N 18947-002401250250
Maybe the EASUN SMH-II 4.2 KW have the same capacitors


Thank you...
