We have a dtr-t2100 which we have been delighted with. Unfortunately now it hangs on startup. The first time around 2 weeks ago when it happend I was I was able after many tries to get it to boot, so that I could perform a factory reset. This time it dies each time on the loading screen - lights go off etc and does not come back even after being left for a day.
No the BTTV subscriptionis no longer active. I had some success. I tried replacing the HDD with an alternative HDD. While it did not accept the new HDD, on refitting the original HDD it offerred me the option to reformat the original drive. That seems to be working for now. Not sure if it will last as I think a dodgy HDD is the source of my problem. Probably bad sectors on it.
I'd be interested to know if there are particular models of HDD drives I need use for replacements.
