Looks slightly like a Philips display module. Does it have an IC built into the board which looks like a "blob" of black epoxy. The Philips ones were well known for failure but the ones I worked on were green.

I agree... Looks identical to the Philips modules.

I just repaired the display on a newly acquired CD202 tonight by flowing solder through all the vias.

Went from having 5 working segments out of 32 to 29 working out of 32 (the missing ones were on the first digit, which always shows "0" anyway)... Not perfect, but a far better result than when I first got it.

Yeah, on the back of the pcb, the pin spacing is a bit different to the one shown, but i guess that might not matter, here is an image of the pin positions -

Still no word from the krell dealer.

Picked up a few led's off ebay which are newer types and have more pins, i don't know if these will even work, although i have had a few segments lit up, without the datasheet for the original units i really don't have a clue....
