I purchased a Lyman DPS 1200 several years ago Unit was DOA. Returned it and got a free replacement. Loaded up 4-5 boxes of ammo and the thing died. Sent it to Lyman and they replaced the keypad. I put the thing on the shelf because it was such a PIA to change powders. I bought the upgrade kit this year and all was well. Loaded a box of 243 perfectly yesterday! Today, the scale won't work. Keypad is operating and it will dispense, but won't stop because the scale continues to read zero. I called Lyman CS, but they are not answering the phone today! Anybody here run into a similar problem?
