Can you send me the instructions as well I am considering this. I'll PM my email address

 

Well I got into the changing of the LCD display. The dissasembly of the speedo is pretty srtraight forward, the toughest part is the removal of the needles. You just have to pry them up.
Now the one issue I have is the actual removal of the old and re-inatallation of the new LCD. The connection to the curcuit board is a flat ribbon cable, no solder is visable. See pictures attached. So my question is for the original creator of this thred, how do you remove the old LCD without damaging the board and install the new LCD?

Well since we did not receive any formal instructions from VRSO2 on how to remove and replace the LCD, i did a little searching on the internet and what I found did not make me too happy.

The only correct way to cennect the "Flex LCD Connector" to a circuit board is a process called "Hot Bar Bonding". It utilizes a pretty expensive machine to lign up, heat up and press together the cable and the circuit board.

See the attached link.

I consider myself very able with tools, but this is one thing that I definately should NOT have tackled. The potential is definately there to completely mess up your entire speedo. I don't care how much soldering experiance someone has, this is an extremaly delicate operation which requires very expensive machinery to carry out correctly.

So until I read a easy-to-follow set of instructions on how to do this, I would discourage anyone from buying these LCD's as there is no easy way to replace them.

On the other hand I could be completely off my rocker and wrong, in that case I would like to ask for vrso2 to forward a set of instructions for everyone to see on how to do this safely and effectively.
