I bought this DW-003 off the 'bay, which needed a battery. I have installed one (10 screws later) and reset it a few times but the sound doesn't work, while everything else does, including the EL backlight...
I tried a "no sound" search but couldn't track any ideas down other than keep resetting it. I should note the module needed to be seated after I opened the back, as it sort of popped up. I think I did that part successfully.
Any thoughts? Also, I was thinking a "Trouble Shooting" subforum might be in order, akin to the How to... threads.
