I own a Dell 1800FP whose Power supply (LG part #:6870T445D10 2003.05.07) is bad. I know this because I have replaced it with a known good power supply and the monitor works fine. I want to fix the power supply so I can have 2 monitors.
1st, I purchased fix it instructions that say to resolder the transistor connections at T901, but my connections there look stellar (perfect). Do you think I can skip this step?
2nd, upon visual inspection of D903, I'm not sure which sections should connect to each other after I'm done. Should just A&B be touching with solder? or just A or what? How does one know without a schematic? Could the browning between the top 3 connections be shorting out the cirucuit?
3rd, there's a lot of other browning on the board (not listed in the instructions of things to resolder) where it looks like the solder got runny. Might these need to be "resoldered" as well?
Thanks for any and all help,
