Working on a motherboard that starts up (fan turns on) but don't get a POST. It's for a multi-game arcade cocktail setup and would like to identify the motherboard (see picture below). Here's the information I've gleamed so far:
AWARD BIOS PCI/PNP 2018 268436163
Chip Set: SiS 651
Southbridge: Sis 962L
CPU: Intel Pentium 4 2.406hz/512/533 sl6rz (socket: 478)
Dimensions: 190mm x 245mm

Re: Physical Electrolytic Cap Size Question

Unfortunately, the parts list states pF, but the actual size is uF. See attached photos.

My question has to do with through-hole Electrolytic Capacitor physical size and finding the correct specification in ordering a replacement.

Example: I'm working on an old video arcade monitor. The parts list calls for two (2) 6800pF, 50V Electrolytic Capacitors (ECap). Based on that specification, you can go to Mouser, DigiKey, etc and get a through-hole ECap at that spec…and get a far smaller one (physical size-wise) than what was on the board.

From my limited knowledge, I understand that size does matter in this application because of the stress that the circuit...

Re: New Members - please post your introductions here

Grew up on the Atari 400/2600/800, IBM XT, video arcade games and have been in IT ever since. Although I'm in management now, my engineering days was focused on telecommunications, networking, and security (Cisco, X.25, X.42, Frame Relay, MPLS, dial-up modem banks, SNA, firewalls, IPS/IDS, and a bunch more)

I've always been very interested in electronics but in the last three years have been able to finally focus on it as a hobby. I enjoy troubleshooting and repairing old arcade games (especially monitors), power...
