Question about Televison & Video

Weak or no signal

The other day I decided to add a cable box so I could watch On Demand through Comcast. Once I hooked it up the message on the screen said ''Weak or no signal''. Comcast wanted to come out but I had decided to just return the box. When I reconnected the cable directly to the the TV from the wall I still got the message ''Weak or no signal''.

I have had this TV since around April 08 and it always worked fine. It was working right before I connected the box but not since. I have also tried connecting the cable to a different TV and it worked fine.

Any ideas?

    I have tried both cable and air in the menu. I do not have an antenna for the analog but I can pick up 2 channels. The picture is weak but stronger than I would have expected with no antenna. I have also tried unplugging the TV for a few minutes, don't know what I expected to happen but it was something to try.

    I am wondering if there could have been a problem with the box that may have caused a problem with my TV.

You would need to know if the tuner is picking up analog signals in the air well( stick a wire a little bit in the tuner connection to see if channels pick up good or use an antenna , if so there should not be a problem with the cable being hooked up to it , if there is a problem even with an antenna then the tuner is bad and will need to be replaced , and the cable could have caused it to go out , but make sure that the tuner is working or not first.

My comcast on demand has been down for over a week, can I fix this myself?


Depends on what the issue is. If you have a cable leak in your home and the noise is getting into your coax "ingress" then yes you can walk around all your cable fittings and tighten them all up. Ingress is white noise or voltage passing into your TV signal coax. This corrupts the data packs your box uses to get to the Cherry picker on demand server and gives you a no access display.

Error message SRM-8012


That is generally a network busy error. Meaning the on demand server is handling too many request at that time. Most often on Fri and Sat nights. However if you get that error all the time it could be a signal problem in your home or even a faulty set top box.

Cable box only works during evening hours.


You need to schedule a service call to meter the feed to the house. You signal is lowest during the day since everyone is taking up bandwidth for internet access, thus dropping the signal to unusable levels. Have them meter the feed from their tower to your main panel then from your main panel to the modem or any box. Hope this helps

Can;t record on VCR since Comcast went Digital


I have Dish Network and a DVR and I do not know what I would do without it. I can record 2 shows at once and watch to 2 recorded programs while recording two shows. But getting to your problem... It sounds like the vcr cannot process the digital signal. You could try hooking up the vcr to the rca inputs from the cable box but you will only be able to record whatever channel the cable box is on. Any way you hook them up the programming of the vcr to change channels at different times for different programs probably won't work now. It sounds like Direct TV with two DVRs will solve your recording needs.

Motorola DCH3200 cable box: sound and sometimes video cutting out


Sounds like your SNR is getting too high and causing the signal to overload. A few things can cause this a bad splitter that causes the signal to bleed and introduces noise, or a more common issue is having a weak signal coming from the cable provider and once it goes through a splitter it causes the signal to become to weak to be stable.

Since it sounds like your cable has been working up until recently, you may have had a cable or splitter go bad.

Call comcast and have a technician come out and test the line.

I'm thinking the Comcast DVR box maybe putting out weird HDMI signals and the TV can't translate it. I would call the Comcast people on this one.
In the meantime, I would try finding another source the uses a HDMI cable to rule out the TV as the problem. Basically, testing the TV to see if the problem still happens when you use something else than the Comcast box. Try a Blueray player, Playstation 3, or Xbox. Just something that uses a HDMI cable.
