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

+5v--21.0A
+12v--10.0A
-12v--0.5A
+5vsb--2.0A

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?...Leave a 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....Last edited by lee123; 03-22-2011, 03:50 PM.Leave a comment:

Re: CCTV capacitors
as its an old pcb and the caps were lose then the plateing in the holes had come away with the solder when removing, so i put new cap in and have left the sitting high so i can solder from other side, will post more photos as soon as i can. thanks lee...Leave a comment:

Re: CCTV capacitors
dam, now replaced 5 caps and still keep rebooting every 5mins, when its cold and on boot up they are 5 chips come up on the monitor display, the 3nd one has a X on it and cams 10, 11, 12, and 13 dont work, also the front panal cam leds 10,11 and 12, are off.
when it get warm thats after about 20mins and 5ish reboots later it seem to be OK and all cams work, no X, and all leds light up,
seanc :- you seem to have come across this board before, have you or anyone got any information that may be helpfull,

Re: CCTV capacitors
thanks for the links, the only thing i would have to wait as in UK
thanks got some from RS 20 in all, cost £0.74 for caps, post and vat cost £6.83 in all
if i leave the legs longer, (about 10mm) as i have to fit them on the other side of the PCB, will that make any differance?

Re: CCTV capacitors
FAKES!!!!! what ever next, Panasonic FC caps sound good to me.
Are they any way to tell fakes? had a look on Mouser.com, DigiKey.com, Farnell.com ether £12. delivery charge or £20 min spend+delivery charge.
thanks for that link.
two more good links, as i'm in the UK i have waited up to 45days to get the from over there.
the cost and time is why i was looking on ebay but i did not know about all the fakes out there, but i do now.
do anyone know...Last edited by lee123; 03-18-2011, 04:15 AM.Leave a comment:

CCTV capacitors
1st of hi all
can anyone help me i have a CCTV box its an adata LJD 16 Colossus and it keep rebooting, "seem to be ok when it get warm"
i have had a good look at the PCB and have found at least 5 capacitors are lose, i did remove and resoldering them, but it seem its a bad design as the pads are under the capacitors, "if you know what i mean" so if i get some new capacitors with longer legs on i could fit them one the other side so i can get to the pads, leavind the legs a bit longer,
so my question is were can i get some of these capacitors "RM 220uf...
