Infinity IL50 issue - is it possible or worth it to fix?

[kmcorolla15]

I have a set of Infinity IL50s that look amazing, but one of them appears to have some damage to the RCA and line/speaker inputs. I had a friend remove the amp module and it looks like the board itself wasn't damaged, but we weren't sure whether just the switches/inputs could be replaced or if the whole module would still need to be replaced. Every module I found online needed repairs, and I'm not paying $175 for a broken one. Is it possible to replace individual switches, or should I just say screw it and get new speakers? Thanks in advance for helping this newbie!

Kind of a tough call. Finding the exact components to replace just the connectors might be difficult. You could theoretically replace them with alternatives that should still work if they are connected via wire and not directly soldered to the board. Though they are nice speakers, unless you REALLY love them, I'd be looking for new speakers.

It is hard to see from the pic if the damage is significant. Are the connections still working?

The connections aren't working at all. It appears that someone bumped the back of the speaker hard enough to knock the connections loose and bend the switch next to them. They were from a storage auction, so who knows how they were loaded into the unit.

With connections not working, I'd say the hit was hard enough to potentially damage the amp beyond just those connections, though the connectors took the hit. Meaning they were not packed in boxes, or not the correct boxes, during their last move. The reason you don't find any working amps is because people aren't likely to sell working ones lol. But it also means failures also aren't uncommon at this age.

Or just use a different amp and bypass this plate amp for the "sub" which the speaker really doesn't have in the first place....

Components like switches and RCA jacks are not too difficult to find. There is PartsExpress, Digikey, Mouser and the biggest selection is probably on AliExpress if you don't mind ordering from China. If someone hit the back of the plate amp hard, I suspect that the damage would go beyond just the switch. It is quite possible that some of the copper tracks on the circuit board were broken, which you can check with a close visual inspection and multi-meter. That does not guarantee that there are no other electrical issues. Whether you are up to the task depends on your experience in electronics repair and how much effort you want to put into it. You could also take the plate amp to a local repair shop and have them give you an estimate.

If the board is not damaged I would bet it is easily repairable. The board will have to be removed though. Remove the board, labelling all the connections carefully, and then take a good picture of where the plugs and switches attach to the board.
