Re: CCTV capacitors
yep.. and this actually looks like a bog standard ATX PSU.
edit: wait.. comparing the size, it looks more like a microATX (a.k.a. SFX) PSU

Re: CCTV capacitors
Yep, crack open the PSU and take pictures please.Comment

Re: CCTV capacitors
well its open, not a lot of room, to get at anything, look to hard to repair it if its the prob, are they a way to test it? first? or put a new one in if i can find a match.Attached FilesLast edited by lee123; 03-22-2011, 03:50 PM.Comment

Re: CCTV capacitors
Are there any bulging capacitors in there?
Are there any brands which are known bad?
You should be able to unscrew the board and take it out of the case if it's hard to see in there..."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: CCTV capacitors
Agreed, snip the zip tie holding the cables in and pull them out. Take more pictures.Comment

Re: CCTV capacitors
cant see any bad caps, cant read brands till i take it apart then it will still be hard.
got to desolder a few wires to get it out just got to find out how to get the iron in there.
could i try a diff PSU, just to see if its the prob first, i have one from an old PC, i bit bigger but is only to try, are these the same?Comment

Re: CCTV capacitors
I have no idea.
Does the PSU you have give any indications as to the output voltages and pinout of the connector?
Is it the same connector as an ATX PSU?"Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: CCTV capacitors
hi its a, fsp groupe inc, model FSP200-60ATV(PF) from an old Acer
200W (+3.3v & +5v=105W)
+3.3v--14.0A
+5v--21.0A
+12v--10.0A
-12v--0.5A
+5vsb--2.0A
all 20 pins (they ony 19 wires) colour code wires match to pins like for like
i think i may be able to find a bigger watt one in an other computer if this ones no good to tryAttached FilesLast edited by lee123; 03-23-2011, 05:56 AM.Comment

Re: CCTV capacitors
well i have tried that PSU, its a little under power, but it has the same fault, so my quess is, its got to be on the PCB board somewereComment

Re: CCTV capacitors
Since you said the problems appear heat related, do you have freezer spray and a hairdryer you can use to see if you can narrow down the culprit?
Never done it myself, but have read about others doing it. I assume this is the kind of scenario you would try it in."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: CCTV capacitors
i think what i'm going to do is replace all the cap on the top PCB board "3 at a time".
also go over as many solder joints that i can with the iron, just to see if they are a dry joint, would i need to use some flux to do this? if so what sort?
thanks lee
good call Agent24, must get me some sprayLast edited by lee123; 03-23-2011, 03:32 PM.Comment

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... -
Hi.
I'm posting this here in part as a memo to self as well as to describe the procedure I used in case anyone else found it useful. I found a lot of the necessary information to make this work on this forum and I figured I would give something back. If this is not the appropriate place to post this, I don't mind it being deleted but I hope it can help other people.

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... -
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...
