Normal on cheap monitors but this one is tough to repair. Usually capacitors and glue turning conductive. Second, this is usually the flyback transformer not stiff enough. Yours is working correctly and no faults. Have to accept that since replacing flyback will not help here. I see this happen on …

Not retro, although some may argue the system is old enough to be retro, as it's not supported in Win 11. I upgrade a sata ssd to 256MB nvme (haven't seen any speed improvements, still takes 31 - 32 seconds to boot and load all start-up apps. 2 days later, the 128MB sata ssd failed BIOS SMART …

FYI 3.3V wires can be totally ignored. If you are running 2.5", just wire up black (gnd) and red (5V). If you need to run either 2.5" and 3.5" wire up red, and yellow and black wires to theirs wires that's 5V, 12V and ground. Cheers,

Many AT PSUs will have the 3.3V plug that looks like third motherboard plug except the wires is two wires in orange (3.3V) and one red 5V, and three wires are black. Get ATX to AT adapter cable and this PSU with this third plug to meet this needs. https://www.ebay.ca/itm/194261003449?hash= …

[quote=dionb post_id=719082 time=1544489575 user_id=37143] I'd say you're being optimistic there. Just looking at my own experience - in 1988 we had a pretty high-end 386-16 with a 60MB HDD. Friends with 286s and 20-40MB drives were jealous! In 1995 my Pentium 60 came with a 540MB HDD. Nothing …

Oooh. You are not supposed to do this with video source like this.

This is not what per service manual says, the service …

Don't forget you need flux paste "no clean" kind, squirt some to coat the underside fully prior to reflowing the BGA IC. Solder crusts up exposed to oxygen instead of perfect clean solder. Cheers,
