Today all of a sudden HDVR3500 stops to work, seems to be stuck in black screen, no way out.
situation till today: HDVR3500's FTA satellite function is working(didn't use much on iptv, etc.)
first accident: after duly starting the box, watched an usual channel A for a while without problem, then switch to channel B, then the screen turn black, buttons on remote don't work, buttons on box front panel dont' work
phenomenum: channel B is on a different satellite with weaker signals. as the wind displaced the dish a little bit, so HDVR3500 seems to be in an endless loop trying in vain to lock on the stream, unresponsive on any push on buttons. I can only switch on/off at the back of box, but that changes nothing. after rebooting, the box would show the initial boot screen, then display "0000" on the front panel then black screen continues.
resolution: I adjusted the dish position to point it at the right direction so the signals come in again, upon this HDVR3500 comes back to life, seems to function as normal. I wonder if I can't get channel B signal back, is HDVR3500 to stay in black screen forever? looks like it is.
second accident: after watching a few active channels, I switched to a non-FTA channel C I saved before. I don't have decode card for that so naturally I can't view it. however, the box goes into black screen again, exactly like in the first accident. As I can get channel C decode I can't get the box at all to work again, since no button in remote or panel works, restart or switch on/off doesn't change anything.
this never happened before during my 1 month+ plus period of using HDVR3500.
I'm on the latest official firmware.
I can telnet into the box using "root" or "stb", but don't know how to fix it.
please can anyone or tech help on this.
