I have two Series 3 HD (TCD652160) models running on Verizon Fios multi-source M-cards, with upgraded drives (1-TB). Both had been running fine for the past few years, but the older of the two of them (almost 5 yrs old) began to freeze unpredictably a few months ago, during live programming and consequently when recording as well - resulting in incomplete recordings. For the past three weeks all I now get is a gray screen all the time - no channels/live TV, no access to recordings, nothing. Also the yellow LED lights 480i, 480p, 1080i no longer illuminate.
Some prior posts have suggested either a faulty cable card or a dead hard drive.
I have restarted a coupled of time with no success in resolving the problem.
I believe the hard drive is a WD caviar Black, but am not 100% certain on that.
Thanks in advance.
