Samsung SyncMaster 932B

[stripe4]

Hello!

An absolute novice here! I came into possession of a Samsung SyncMaster 932B monitor that has the infamous "2 seconds then black" problem... So I took it apart and saw that the PSU board has 2 CapXon caps bulging.
I plan to recap the board but I want to make sure I have picked the right substitutes.

CapXon spec sheets are here:




The original capacitors and my planned substitutes are:

CapXon 1uF 50V KM 105C
RUBYCON 50ML1M4X5 CAPACITOR, 1UF, 50V
http://lv.farnell.com/jsp/search/pro...sp?sku=8126933
I am most concerned about this one as CapXon has 13mA ripple current but my planned Rubycon has 8mA ripple current. Sadly I do not have much choice as Farnell does not have better options. Perharps this one (can I use 130C instead of 105C)?

CapXon 47uF 50V KM 105C
RUBYCON 50YXF47M6.3X11 CAPACITOR, 47UF, 50V
http://lv.farnell.com/jsp/search/pro...33&Ntt=1144633
I already have these Rubycons from my previous recap job.

CapXon 330uF 10V KM 105C
RUBYCON 10ZLJ330M6.3X11 CAPACITOR, RADIAL, 10V, 330UF
http://lv.farnell.com/jsp/search/pro...sp?sku=1831266
Or maybe I can use the one below as I have it from my previous recap job?
PANASONIC EEUFR1E331 CAPACITOR, RADIAL, 25V, 330UF
http://lv.farnell.com/jsp/search/pro...48&Ntt=1800648

CapXon 470uF 25V GL 105C
PANASONIC EEUFM1E471L CAPACITOR, RADIAL, 470UF, 25V
http://lv.farnell.com/jsp/search/pro...sp?sku=1219470
This one is slightly longer in size but I think it will fit.

CapXon 820uF 25V GL 105C
PANASONIC EEUFR1E821 CAPACITOR, RADIAL, 25V, 820UF
http://lv.farnell.com/jsp/search/pro...53&Ntt=1800653
I have this one from my previous recap job.

CapXon 1000uF 10V KM 105C
PANASONIC EEUFM1A102L CAPACITOR, RADIAL, 1000UF, 10V
http://lv.farnell.com/jsp/search/pro...sp?sku=1219456
This one is slightly longer in size but I think it will fit.

I will double check tomorrow if my selected capacitors actually fit when the monitor will be reassembled again.


Thanks in advance,
Janis

Hey Janis, you can go with 130 degrees for the caps. But it will be more expensive than the ones 105 degrees.

Thanks, stan999 for your answer!
I measured the space available for the replacement caps. If I go for the 20mm (in height) ones, the caps' tops will slightly touch the plastic. I assume it is not rather good... but is it bad?
