Emax

Hi Mike,

It's a bit of a sorry tail of woe. The dim backlight didn't bother me  
too much, but there was a background high pitch whine that some  
people attributed to the lcd so, after buggering up the original one  
by shoving bits of cardboard behind it, as advised, I thought I may  
as well completely replace the module.

The one I got conforms as closely to the recommended replacement as  
any I could find, but the documentation on it is all a bit  
overwhelming and confusing for a novice like me.

I desoldered the original one away from the pins that connect it to  
the board, leaving the pins in place. I cleaned up the pins and  
plugged them straight into the aligning holes on the lcd module. I  
then tried cautiously powering it up without committing to any  
soldering. I get no response at all. What worries me more is that no  
LED's come on either, although the floppy drive does start spinning.

Could it be that I need to bite the bullet and actually solder the  
thing in place? I have wiggled the module in place while powered up  
in case the contacts just aren't firm enough, but it seems to make no  
difference.

Any suggestions?

Thanks,
Alan
