I own six Mitras LX 7206 and I recently starting to have an issue with two of the units. In the past week, I have found two of them off in the morning. The display is completely dead but the GHL logo is flashing on and off about a second apart. If I power cycle the units, they come back online and will function normally for a time. Of the two units, the one unit failed twice but the other one has failed at least 6 times. I am running firmware version 1.10.

Thank you.
