So picked up a SC recently (Loving it!), however it has a slight annoyance in that there seem to be a few lights out of sync in the backbox. May be better explained by checking the following link...

So - it seems that as can be seen around 23 seconds, a pair of led's come on...(in test, L16 lights L16 and L17) and somehow, this moves all the rest following out of sync - meaning that L17 Lights what L18 should be etc etc This carrys on until L24 at 38 Seconds... and it ignores L24 altogether, and then

There also seems to be an issue around 1:06, where both the Vault and L41 come on at the same time.

Finally, have attached a pic which illustrates a little more the issue - The four Alarm bells should be lit, however the bottom right is one light on from that!

Very weird one - Has anyone come accross this before, or can anyone make sense of the circuit diagrams enough to advise where to start??!! It does say it's the technical forum... and this most certainly is!

Many thanks!
Paul

Skywalker - you star! I have to admit I'm a little hacked off as i was looking at the cct diagram and did think about the 4094's, however guessed (rather incorrectly) that.... Nahh only one would go - not a bunch of them!

Loads of thanks for your help and pointers - I'll get some ordered and change them out

Cheers
Paul
