A few months ago I read about LCDs that went totally dark. The document said, emphasis theirs: "Your problem IS a bad solder joint in the lamp power supply board and it is likely associated with the larger wires on its inductors." I took the thing apart and hit the larger solder joints with an iron and some rosin flux and the display came to life and ran for almost a year until the same thing happened. It's sitting on my workbench now. Cracked solder joints often respond to a sharp tap that accelerates the circuit board edge-wise a bit. Not as much as a sledgehammer but sharp. Your symptoms sound a bit like that. -- --> A fair tax is one that you pay but I don't <-- --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
