suddenly everything worked alone normally :)
i can't understand what happenned
receivers are like computers--temperamental. :)
I used to have an issue with a receiver so I connected it to another cable to see if it was issue and voila--it started working again. It did it a few times and I fixed it the same way. Eventually, the electricity got to it and it literally burned up.
Rest in cinders.
