Re: Cable box will not turn on

Same problem here! I don't get a screen or message at all. It's like my box isn't getting power. Tried plugging into different outlets and still nothing. Then Comcast tells me I may have to pay for it. How is this my problem? This is not the first time the power has gone out and I have NEVER had this issue. So frustrating!

Re: Cable box will not turn on

Thanks much for your reply.  I will now give it a try. It's never been on 'EXT', so was baffled. Maybe this will do it.  Have a good Friday.

How is your cable box hooked to your TV set? The "EXT" is for external source, so it you are hooked up using coax, you need to press the "input" button on your TV's remote.

Re: Cable box will not turn on

I'm having the same problem.  After a brief power outage none of my boxes work.  I've tried everything to no avail. I called Comcast and was told the soonest they could get out here is Sunday.  That's 4 days from now.  A weekend of bowl football and no service?  Come on Comcast. Winter means bad weather which means cable outages requiring tech calls. Hire more techs!

Re: Cable box will not turn on

your cable box should always be able to turn on unless the power supply to it is dead, which is a rare occurance.  When you plug it in and press power what does it do?  just because it does not show you a picture to your tv does not mean it is not powering on.
