I've heard of several people having problems with the no zap cams crObar, now whether there has been a faulty batch or there are compatibility problems is a different matter. Have you tried resetting the cam by switching the power off and on again a couple of times?
No-Zap on Astra19.2 actually tells that not all CI recievers are compatible, I don't remember which, but it was a long list of CI recievers. I can't check it now because I'm listening to music on 26.0East, and I don't have a motor so it is confusing to manually change the position 10 times aday.
Sky HD, TM6800HD, Manhattan Plaza ST550 and TM1500 CI+. 1.0m dish and 36v motor, Panasonic DVD HDD recorder and Panasonic video/DVD recorder. Sony G800 HD TV stand/surround system + Sony KDL40W2000. Infinity USB, Elvis, CAS1, CAS2.
There is a bit of news on No-Zap which may help you cr0bar if you don't already know. The channel has had uplink problems leaving some viewers without a service. To combat this it has launched a second TP on Hotbird (13deg E) at 12.520Ghz (SR: 27500, FEC:3/4). Best of luck.
