Bad lightning the other night. Big bolt knocked out everything and flipped some breakers. After flipping the breakers back I walked around the house turning everything back on one by one. Eventually I got to the cable box. Turned it back on and it looks like it is working fine. Boots up , shows the clock and shows signal just like when it is on. Problem is that there is nothing on the TV. Nothing, nada, zip zero zilch. It looks like there is no box connected at all.
Here is what I tried:
1. Changed the HDMI cable thinking it might have gotten fried. No good. I used the cable on other devices and it works fine with other devices. So it's not the HDMI cable.
2. Checked the TV. Plugged other HDMI devices using the same cable to the same port and they display fine. So it's not the TV or that particular HDMI port.
3. I tried the cable box on another TV to be sure and it does not display anything on 2 other TVs too.
4. I changed cable boxes. I took the box to Cox office thinking it was fried and they gave me a new (new to me at least) box shrink wrapped. Brought it home plugged it in and exactly the same thing! So I'm guessing it was not my box.
So now I called tech support and the support guy was stumped. After going through all the regular things like making me power cycle the box :uhh: he is sending a tech out tomorrow.
But here's my big question. Even if there is no cable at all connected to the box, shouldn't it be send something to the TV? Shouldn't it at least pop up a dialog saying that there is no signal? My feeling was that the problem had to be between the box and my TV. But after getting a totally new different box supposedly checked by Cox the same thing happens, so I am starting to think that it may be something from the cable. But how can that be?
