Long term storage of my LC575 - tested today and no longer boots. Ughh. Pulled board and while caps look ok (I plan to replace them all of course), I noticed that a component labelled LP1 (marked 'PECKO 0063' on mine, but on other boards I have seen online is 'Steward 430-2 155-0064'. I think it is a ferrite filter of some sort) near U12 (see image) had corrosion that was bad enough that the pad closest to the LP1 label is entirely gone. I removed the component , cleaned the 5 pads which looked good and put it back leaving the 1 pin unconnected. Using microscope I could not see even a hint of where the pad might have been connected to. No schematic so I have no idea where to connect a jumper wire. Image is from online but shows the connection that is missing. Any ideas where this should connect to? Much appreciated.
