Element FLX-3710 Need cap size for 860-AZ0-GF371H MLT070A

Hello.

I am working on a Element FLX-3710. Typical bad power supply with the 2 matched caps. The problem I have is the power supply has 1000uf/50 volt caps (bulged) and look like they were already replaced at some point. i ordered a kit and I received (2) 1000uf/10V instead of 50V caps. I thought the 50v was odd as I usually dont see that voltage range installed in these. Regardless, does anyone have experience with this specific power supply and be able to tell me what the correct values are? Location C112 and adjoining (sorry cant find the location id)...dont want to install 10v rated caps and damage something else.'
Thanks

Here is a picture from the internet showing the caps. It has 35Volt caps but they may have been replaced also. The originals may have been 10 volt thats one of the resons why they failed,

Are they the caps for +5V power supply, the two by the small transformer with MLTxxx sticker on top?

Hi budm,

Yes they are the two caps by the small transformer as you described.

install the caps and if it fires up, check to see what the voltage is at the caps.
if it is 5 volts a 10volt cap is good
if it is 12 volts 16 or 25 works
if 24 volts 35v will work

someone may have put 50 in thinking 50 was better than 10, but they may not have paid attention to esr or to amps on that 50


The two tall ones at the top of you picture and between the second largest heat sink and small transformer look like they are marked 25 volts

I assume I can do the voltage check with the bulged caps installed? It does fire up but has static and all sorts of weird responses. It looks from the back as though someone already had replaced those caps with 50V based on the solder markings, but they are bulged.

voltage might be off a bit with blown caps, but it should be in the general area.
you can also backtrack the traces from the pins that go to the main board if they are labeled for voltage

I think that is the 5 volt side which should be on even with the main disconnected
