I copied this description from an archieved post, as it exactly what is happening but there was no replies / answers. Any help would be appreciated !
When the cable box and TV are initially turned on, there is loud static and very fuzzy picture. The remote locks up and doesn't allow the box to be turned off. After 20 to 30 seconds the unit turns off. Turning it back on then has a normal picture and sound. I have rebooted the box several times but it does solve the problem. Any suggestions?

We're sorry to hear that, kafoka. The next step in the troubleshooting your issue will be to send a repair technician out to your home to inspect the wiring setup and possibly replace the box.
