Jodav/Lac, just to further explain when I try to change channels or volume using remote up & down or volume or any other button they is no immediate response, does not change channels or volume immediately, it just stays on existing channel, then several seconds 5 to 10 later it will change, what I have noticed so far is when the lights start to flash on the modem then you can change channel using the remote, but if the lights are solid and not flashing it won't change channel it just freezes in other words although I am pushing the button to change channel nothing is happening, the batteries are new "duracell" and been tested also tried with a spare fully working remote control and still same outcome, turned off both modem and box 30 seconds no joy, I will try what you suggested Jodav and get back to you tomorrow ...............Lac BOX IS A 780 not sure what you mean "using a cell phone, point it at the I/R on remote, press any button I/R should light up" can you explain tried 4 phones and 2 remotes & new batteries none of us can work that out.
