SID panel Repair

SID Panel Repair
by Leon Murphy

Remove SID Unit, I found by removing the 2 switch blanks next to SID I could push panel out from behind

Press in plug retention clip as shown, and lift plug at a right angle

Pull cable plug to 90 degrees and remove

There are 4 Torx8 screws to be removed to gain access to the SID internals

Once you have removed the 4 screws, carefully pull up the connector housing cover

There are now 4 press tabs to be released around the units fascia, carefully push these down using a small flat blade screwdriver, at the same time applying pressure to remove the units back housing

The housing should pull cleanly off easily, if its tough, check all press tabs are released!

There are now another 3 screws to remove, once removed the actual LCD panel and board can be separated from fascia

Now you will need to very carefully separate the LCD panel from the main PCB, there is a plug on one corner, remove carefully so not to suddenly pull apart and damage ribbon cable!

Now carefully lay the 2 parts apart on some anti static foam/mat, this will reveal the ribbon cable, the most common cause of SID failures

Using something reasonably blunt (I found biro worked well) apply pressure along each contact of the ribbon cable, this will hopefully realign any lost contact

Now once you've gone across all contacts, carefully reassemble the unit, on re-assembly I also fitted a piece of card between the LCD panel/ribbon contacts and main PCB.
Also ensure the PCB slides into the guides of the back cover.

And hopefully the end result will look something like this!
