ADDCO DH1000 Message Board Trailer Stuck on One Message

I have a 2006 ADDCO DH1000 message board trailer that I recently purchased. The trailer is in excellent condition all around with the exception that when I turn the power on and the current message operates properly, I am unable to get the keypad to respond with anything other than "PLEASE WAIT..." Therefore, I can't program any other messages to display on the board. I've called ADDCO a number of times and left messages requesting to purchase an operator's manual, but they have yet to return my calls. Internet searches turn up little to no information on these machines, and there's no one in my neck of the woods that repairs this equipment. I've tried rebooting, checked for proper grounds, and I replaced the dead battery in the control unit, but still no luck. Any information would be much appreciated. Thank you.

I have manuals I can send you .Whats is your email address .If you want email me at [email protected] . You might have a hand held controller that went bad .I have had one go bad in the past on a unit . thanks ED

Thanks Ed. My email is [email protected] . How would I know if the hand held controller is bad?

bobfunghoul I just email you manuals to your email address.What number did you call for Addco ?I have two number for you 1-800-616-4408 toll free or 651-488-8600.

Hi bobfunghoul Did you have any luck getting your sign running? I recently purchased the same sign and am experiencing the same issue. I found if I leave it on the “please wait” screen for about 30 - 40 minutes, then turned the battery isolator off and straight back on. The system will boot up correctly. I now have another issue, where the HHT says press any key to continue. When I press a key, I get a key tone but it continues to say press any key to continue. Has anyone experienced this or have any suggestions? Thanks, in advance Adam

Adam, From my understanding, it's the hand held controller that is the issue. It's a big chunk of change for me to purchase new, and it may not be the problem. So I've been hoping for a reasonably priced one to come up on ebay. I don't know if there is anyone out there that rebuilds them. Right now, I'm not even getting the "please wait" prompt anymore. Ed offered to to help me out with the issue but I got caught up with another project and I just let too much time pass to bother him. Thanks anyway, Ed. My apologies. Anthony

Thanks Anthony, hope you get it running. Cheers Adam

Thanks, Adam. If anything comes up I'll let you know. Be well. Anthony

How ever i have three cells that dont display at the end and now all my messages are missing the first thee letters. i moved the board in three spaces thinking the Led panels might be bad and still the same issue.
