CCTV capacitors

Re: CCTV capacitors

I think no.
My take is the asker tried to remove and re-install the old caps and the legs were too short.

yep to short.

OH NO!
Channel Well likes Fuhjyyu caps

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.

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.

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...

Re: CCTV capacitors

Agreed, snip the zip tie holding the cables in and pull them out. Take more pictures.

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?

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?

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 try

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 somewere

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.

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 spray
