Model is: DTR-Z250
Purchased 2012 (approx 2 yrs old)
No lights or any response - completely dead.
Not that I know of, sorry. TV and computer were both working.
Personally, I think it's just kaput, but then I'm not an expert lol
Thank you anyway, Michael, for your assistance.
Thanks for the offer, Michael, but I must decline.
Purchased a new device which is working splendidly.
