I've got a couple HLZ's that keep going into high and lock out the buttons on front, but once you unplug it and let it cool down, the buttons work just fine for another 24 hours or so. Just wondering if that's normal for happening when the computer for the HLZ's are going bad because once I change out the computer for the HLZ's the problem goes away.Name:  ImageUploadedByTapatalk1343419926.458861.jpg
