Re: A3640 problem & A4000 questions

Sorry to have rekindled this thread again, but I have uncovered the same problem with my A3640 Rev. 3.1 board.  I have followed this thread as wells as the article written by James Jackson on this very subject, but I have a couple of questions I would like to cast out to the techies.  1) Can I use the radial versions of the capacitors 22uf 16volts, or must I use the SMT versions?  2) Can I use a higher voltage like Jame Jackson eluded to in his article(i.e. 22uf 25volts)?    I have removed all the caps C106(leaked), C105(leaked), C107(leaked), C102B(it appeared to have leaked), C102E (Did not leak, but removed just the same).  Before proceeding with my Cap removal I tested with a good A4000 mobo and memory, all I was getting was a purple screen with the hard drive light constantly lit.  Then tested mobo with A3600 '030/25 CPU card and booted right up.  So, that is what isolated my attention to the A3640 and the Cap problem.  Thanks for any help....

Thanks for the information.  It was most helpful.  My questions were not directly answered, but the links provided  were very helpful.  Thanks, Mike.
