I am rebuilding one of my boards and there are really small caps of 10uf -25v/22uf -25 ... I was checking them out today and noticed that alot of them had rusty color residue under each of them and let me guess I have to replace them too because they are leaking ??? If this true them I will be buying over 100 Capacitors for a single t.v.....

Re: Capacitors
If they are leaking then yes. Could you post some pictures? Those caps are really cheap. With the price break on Digi-Key 100 of those sized caps is under $10 before shipping. Time consuming...yes. Expensive? no

Can you get some more clear pictures? Is there a macro mode?Last edited by Pentium4; 11-26-2012, 06:10 PM.Comment

Re: Capacitors
Is it under every single one of them? If so, it could just be grime deposits. See if there is a similar brown residue on or under anything else that has no electrolyte to leak out.Comment

Re: Capacitors
I can't tell from the pics, is this looking more like brown gunk with dust in it, which probably isn't electrolyte, or more of a crusty lighter colored substance? From what I can see I'd leave the caps in, it's unusual to see ALL of them leaking unless they were all in parallel or complimentary portions of a PSU subcircuit which wouldn't usually use small caps like those.
What was the initial problem with the TV?Comment

Re: Capacitors
They might be leaking, or it might just be leftover flux.
BTW, 'Decon' caps are crap...Muh-soggy-kneeComment

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 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... -
I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow
This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board
After all of... -
I picked up a 70" Samsung UN70TU7000WXZA. The original owner said they were watching it when the power surged and knocked it out. I pulled the back off the TV and disconnected the main board from the power board, and the LED backlight came on, which I was told meant the power board was good. When everything is plugged in the standby light will not come on, looking at the main board BN94-17775A with a thermal imaging gun I can see one of the chips labeled 3202 is 251 degrees F just sitting idle. I found a replacement board, BN94-16115X; this board has the same symptoms, except it is a different... -
Hi All,
I recently purchased as MSI RTX 2080 SEAHAWK X, which isn't working. I noticed there are 2 capacitors missing from the back- see images. I am wondering, could this explain why the card won't work? I appreciate any help!11-12-2024, 12:20 PM
