So in follow up to prior post (thanks Chris Groff) I decided i will give this a whirl. We all have little intricate things we prefer to get more heavily involved in then others. Board repair stuff has been of considerable interest to me for a long time, but is a little difficult to completely make it a profitable thing in any large scale....I think? I am sure there is a bunch of people here who are doing board repairs

We are totally in a throw away society, and as far as vehicles are concerned it is almost a reasonable argument that these electronic devices should rather be discarded than repaired. But on the other hand, when the devices are rather expensive and solution can be found things can be done so that all parties win. Client pays less for the repair on an existing part, shop can make as much money on a repair as they would have by selling a new part..... (and I get a little cash money on the side for doing this at home in my man cave :) and.... one more part stays out of the landfill

However, the troublesome thing is, where can one source schematics for the boards in question? I have tried getting in contact with companies like bosch and delphi to see if there would be a source we could get schematics for various different modules made by say Bosch..... But its usually radio silence or the reply back is "that is only for internal use" and so on. So that leaves us to compare notes with each other and lots of trial and error etc etc, which again makes it difficult to get too much into such repairs. Anyone here have access to such documents or would know sources on where they can be purchased?

In the title i posted the VIN just because I thought I should. This is the IPC from that Van and you can see from the picture it took me some practice to get some LEDs back on the board which still worked after I was done. I cannibalized some off a Savana IPC I had laying around. Maybe an assortment of these LEds could be purchased from the electronics stores..? I might look into that.

Maynard, Glad to see you posting and I hope to see more in the future, though there is no need to thank me. We are all here to learn from each other, as well as to teach each other. I agree completely with the throw away society comment. I often get ahold of old modules and the like, I get them working sometimes and use them to play around with networks and such, nothing nearly as constructive

Chris, maybe more people will put stuff up that they have fixed. There is some pretty cool facebook groups where this work is the main topic of discussion. I posted this over there but can here as well, likely 1 of my favorite modifications so far. This is my personal vehicle, so all legal matters aside, When people live in Canada and the odometer reads in km rather than miles, on certain Toyota

Nice work, I have a stereo shop just down the road that does this stuff everyday. If you have the time and skill it can be worth it. I usually pull the cluster and send it down. Unless I have time to tinker. I know they buy a lot of stuff from digikey​.​ca , they have a mass of products.

I do board Repair my self and have not found a source to get any schematics so what you need to do is reverse engineering! It takes a little time and practice but you’ll get better every day. As far as parts depends of what you are looking for. For instrument cluster if you are doing just a few a month then buy on amazon, you can get complete kits with step motors, LEDs. If you need parts for
