When the Video On-Demand feature on your Comcast cable box stops working, an error code message will appear on your TV screen. The most common error code encountered when the On-Demand won't work is the "E1003 error" code. This could mean that there is interference in your cable signal caused by faulty wiring at the cable splitter box in the house, or it may be because of the cable line that feeds into your home.
E1003 Error Codes
If you can access the On-Demand main menu, but when you select a show to watch you get a message telling you that you have a set-top interactivity problem or Error "E1003," you either have a faulty set-top cable box, or you ordered a channel package upgrade that has not been completed in the Comcast computer system. Call customer service and speak to a representative or e-mail them.
Unable to Process Request
If you see the message "Unable to process request," "s0a00," "error 7," "65532," "cl-7," "err-36896" or "SRM-8" it means that your cable converter box can't communicate with the On-Demand system. Wait five minutes and try again. If you still see this message, turn off your cable box, wait five minutes and turn it on again to re-boot it to get the On-Demand to work.
Check Your Equipment
You may have the wrong cords leading from your cable box to your television. Unplug all of your equipment, including the power on the cable box and go through all of the wiring. If you have a splitter, which looks like an electrical outlet with three female coaxial plugs, it may be that the cable TV splitter was not installed correctly. Try attaching your cable box to the other splitters and turning on the cable to see if this fixes your problems. If it doesn't you may need to replace the splitter or coaxial cable because the wires in the cables may be faulty and causing the problem.
Check your Services
You may have a cable television package that does not include Video On-Demand, or you may live in an area that does not provide it. Call and speak to a Comcast representative to see if you can get it added to your cable.
