[sdiy] Emu XL7 Keypad - Light Sensor

[foRUMS 4 punkdISCO]

Hi all

 

I have a new Emu XL7 (a complete blast!) but one of the keypads is very
flaky (mainly dead).

 

It is definitely not the rubber pad or the rubber contacts.  I've cleaned
these all up and done various experiments..

 

I think the issue is a flaky light sensor of some description..  In the
below picture, the square component marked U1 is some sort of light sensor;
you can trigger the sounds by putting your finger over these.  Anyway, the
faulty one I can get working by pressing it around a bit but after I
re-assemble, it eventually stops working again.

So my questions are:

 

1)      What is this component?

2)      Will it be easy to find a modern replacement?

3)      It's VERY small so is it going to be impossible to swap out?

 

Big thanks for any reply's..
