It was shocking and tell you honestly. I almost gave up repairing this unit. But as other knew me. I do not easily give up. There will always be a way when circuitry isn't damage, and or parts inside is not missing.
As I am dismantling this at first seems OK. Getting deeper from the dismantle process.
Someone of no knowledge actually repaired this one. The actual display has some missing digits and speed reading no longer functional. Probably due to not properly fixed.
Ok then getting deeper.
Here we can see what was behind that glue stick. Wow a Glue stick. Very clever huh! Broken board that snap in two pieces must be joined by something else. Aside from the stick glue. They tried to use a cynoacrylate just like mighty bond. How bad they were thinking. As I am tearing it apart, Been thinking how in the world that this speedometer board got into this kind of situation given that it didnt came from an accident or a hard knock to simply snap the board. Do not even have a clue why? nonetheless this unit will still be repaired and make it functional again.
And so cleaning here removing the glue and moving on the repair each and every broken copper foil path must be joined by just using some enameled copper wire as shown,
cleaned it first with 100% iso alcohol scrape all coated path to be joined and voila!!! looking good.
Board is 2 layer top and bottom so both sides must be securely joined by solid wire.
LCD missing pads must be tied with an enameled thin copper wire. as shown.
Checking everything after all connections was done and after turning it on was a success. Who would have thought a broken PCB board cannot be fixed and turn a non functional unit into a working item. Everything needs patience. There is no impossible fix. Just doing the right approach and you'll get what you wanted and get things done right.
