Step 2

• The C928 Capacitor 100uF 25v is the one talked about in the forum mentioned in the intro.
• While I was checking the solder side of the board I noticed there was a bad solder joint on this cap. You cant see it at this resolution though.
• While checking the state of the other caps on the board I noticed that this one 1000uF 10v was also showing signs of heat stress.
• Both capacitors were replaced.
• You can see the new caps in position on the right.
• For the princely sum AU $1.20 in parts, 20 mins setting up, 5 mins to fix, 5 mins to put it all away I have saved myself aprox $200 for a new VOIP router :)
