Question about Infinity BASSLINK Car Subwoofer
Have a basslink in the trunk of my car, loved it for 2-3 years now! went out recently- green servo light is on constantly. removed inputs and remote wire so power and ground only, still servo on. turned all controlls to minimum, fuses fine, red power light fine? out of warranty. really like to fix it. anyone know if way to reset or is amp blown? thanx in advance
So, thanks to the other posters here for getting everyone close the issue that brakes these things! I wanted to pile on, as I repaired mine. See the pics, but yes, you're going to want to get near the power resistors and transistors called out earlier - they COULD be failed, so you will need to do what I did and isolate them to test them (within goo electronic principles). For example, I have a Super Cricket transistor checker that will do the job in-circuit. Many of you will need to remove them to test them for gain with the right meter.
You can see in my pics that the resistors have cooked the caked sealant material, but the resistors themselves were intact and tested right at 3 ohms (correct). So, those weren't bad. However, one power transistor tested bad, so I removed it...to see it test well on the bench? Huh! So, I put it back in, and then notice that the solder pads to both locations were nasty in the original pics I took - they'd CRACKED at the pads! So, cold/cracked solder joints were the culprit here. I reflowed them and the amp powered back up nicely on the bench.
Again, check the pics they show where I had to do the work!
