1) You want to replace ALL the electrolytic caps on the board especially if they are poor reliability brands like Capxon. The exception would be the largest filter cap which rarely, but not never, fails.

Capacitors (C designation on the PCB board) die from age, heat, and shoddy build quality. Capacitors DO NOT have to be visibly bloated in order to bad. They can be out of tolerance uF (a 1000uF measures 20uF) and/or have high ESR (ohm). A multimeter will be insufficient to test for ESR. For that you need an ESR tester which costs between $50 and $300.

Most members here will recommend that you replace ALL capacitors with reputable brands from reputable sellers. Brands like Rubycon, Panasonic, Nichicon, and United Chemicon are suggested. A list of recommended caps can be found at

2) Assuming those are Capxon GF series, you want to replace the caps with the following critera:

a) uF - same uF
b) V - same voltage
c) ripple - same or more ripple
d) ESR - same or lower ESR
e) size - you want to make sure the cap fits diameter and height wise

3) The Capxon GF datasheet is at

Look for 1500uF 35V. Assuming the original is 13x35mm, then the ripple is 3350 ma and ESR is 18 mOhm.

4) Now compare that to Panasonic FR series at

Caxpon GF, 1500uF 35V, 13x35mm, ripple = 3350 ma, ESR = 18 mOhm
Panasonic FR, 1500uF 35V, 12.5x30mm, ripple = 3630 ma, ESR = 13 mOhm

5) You can see Panasonic FR is a good match compared to Capxon GF as it has the same or more ripple and the same or lower ESR.

6) Now repeat for all the other caps. You can quickly search in digikey by specifying this in the search field

1500uf 35v fr

7) If "FR" is not in stock or available in those parameters, try FM, then FC (in that order).

Just for fun, here is Panasonic FM

Caxpon GF, 1500uF 35V, 13x35mm, ripple = 3350 ma, ESR = 18 mOhm
Panasonic FM, 1500uF 35V, 12.5x35mm, ripple = 3750 ma, ESR = 12 mOhm

If you are new to this forum, we can help a lot more if you please post clear focused pictures (max resolution 2000x2000 and 2MB) of your boards using the manage attachments button so they are hosted here. Information and picture clarity compositions should look like this post.

We respectfully ask that you make some time and effort to read some of the guides available for basic troubleshooting. After you have read through them, then ask clarification questions or report your findings.

Please do not post inline and offsite as they slow down the loading of pages.
