Fixing your digital dash

Post by Bugle »

Thanks to Leon, thought it should be posted in here.

As mentioned befor with my dash it was the power supply board on the dash main board which was the problem.... Trying to post some pics for your viewing pleasure....

So where did you actually solder?

He just resoldered all the farked solder joints. After a while solder joints can crack and cause intermittent problems. It's pretty easy to see the cracks going around the joint, sometimes not so easy to see. Best off re-soldering every single joint.
I'm sure mine has the problem once it wouldn't turn on at all then few hours later it was fine again. Also a couple of bars of my tacho aren't working I think the whole VFD would fuck up rather than just 2 bars so it's probably the solder..

Its just like an old TV. lol.

Good pics Bugle. 10 out of 10.

At a guess id say the solder itself is the main culprit. Solder is made up of all sorts of stuff parts of which would be corrodable. Add in age and vibration too.
Ditto for the copper tracks on the circuit board it can corrode too if exposed to air.

Id say to be doing a job like that you want a clean fine tipped soldering iron. No gunk on the tip clean it up with a wire brush. Use as little heat as possible so you dont upset the electrical bits.

So how did you get the power supply board off? did you just snap it off? Or did yours slide right off? coz mine is soldered on very solid.

You have to remove all the solder on each of the pins then it'll slide out

To do that you'll need a solder sucker or solder wick. Couldn't find a sucker thing on jaycar but here's the wick stuff link

I'm surprised they have the board suspended there only supported by solder. That's asking for trouble!
