Wow that board is dirty. Is that flux residue? Looks like someone touched up that board and didn’t clean it after.
I don’t think it’s flux. I think the chip labeled IC001 burned up and that’s spatter. Hard to see from the pic but the side is melted out. I haven’t tested to see if those traces are burned. Once I discovered the chip was obsolete I just closed it back up and put it back on the shelf. That one is a 94 thunderbird non-premium radio, so I don’t have another one like it to parts swap. It’s forever stuck on tape, but doesn’t actually play.
I am curious if the circuit boards very from similar radios in other cars? Do we need to start snagging F150 and Crown Vic radios for their chips?
The radios aren’t all the same. Still trying to get a sense for it, but it does seem like radios from other 93-95 fords were similar, but later 97-01 radios changed internally. Differnt conponents and such. Even the 87-92 amp wasn’t the same. It changed a couple times and the graphic equalizer radio got a different one.
I do have an original 93 cassette and cd player, although both are busted, but it seems a lot of 93-94 Lincoln’s and other ford radios share the same basic internals.
I fixed one radio that wouldn’t power on ( bad trace) but the CS player isn’t working and the sound is quiet/terrible. Another radio just shows this
You don’t say?
I’ve got maybe a dozen or so of these style cd players and tape decks that have various issues. Trying to parts swap them into some fully functional units.
This 94 Lincoln deck sounds great, but the tape doesn’t work. It’s similar to the 93 mustang unit. Trying to figure out where to tap the right and left channel to add Bluetooth. I found the individual 4-channels to the amp, but I need the left and right channel.
I did find a guy on eBay who was an audio tech unloading all his service manuals. I bought one for a similar 1993 style radio so I hope it gives me enough info to be dangerous. We will see. There’s no reference or schematics for these. The unit above shows BaD but there’s no service doc that tells me what that means exactly. I’m basically poking around and learning.
BTw, if you guys have busted 87-93 radios and amps, I’ll take them. Premium, non-premium, etc. Looking for broken stuff so I can mess around and see how they work to repair them.
