We have a QIP2500-3 STB. About once a week the time displayed on the box when it is off will freeze during the early morning hours. The colon will blink but the time will stay frozen at something like 2:50 (am). When the box is turned on the clock resets to the correct time. We turn the box off when we are finished watching TV for the day because we want the clock on in the room at night. When the box is on, we have it set to display the current channel. This problem started about 3 months ago.
A support technician performed a hard reset to the box and when it happened again the next technician had the box replaced. It happened this morning on the new box.
I called Verizon support this morning and the technician told me he had 6 years experience on the job and never heard of this problem. He went on to say that it was not a problem - the only things that were problems were when the box malfunctions while watching TV. He also said that turning the box off was a no-no. When I told him that the clock did not freeze for the first 3 years that we had FIOS he said that changes were made all the time and now I should not turn off the box.
I see that "figsgrandpa" posted this exact same problem to this forum on 11-14-2011 and traced the start of his issue to the 1.9 upgrade.
So there IS a problem. I suspect there are many people out there just living with this issue or do not know about it because they leave their boxes on. Hopefully someone at Verizon will read this post, acknowledge the problem and plan a fix for an upcoming upgrade.
