Re: Dell GX620
Hi all
I have just got a used mobo Dell Optiplex 755. The mobo code is OGM819-13740 assembled in China. Two capacitors have been replaced by Nichicon 1000uF-85oC. They are C667 near internal spk socket and C502 b/w the CPU and the North bridge. I would appreciate if you could help me with the exact value of the capacitors which have been replaced.
Thank you

Re: Asrock 775V88+ Mobo
Coud you try to locate a SMD transistor positioned nearby the power-on/reset pins. I used to detect a broken B pole. I replace it with a NPN 600ma general purpose transistor and it is fixed. Another Asrock 845 got the same symtom but this one has a defective TL431 located near the south bridge.
A "special" characteristic of Asrock mobo is that it does not work with "aging" IDE cable while other mobos were not affected.
Hope that would helpLeave a comment:
