I have a problem with my TV / receiver / Bell HDTV box.
When the TV is on the picture and sound is good, then the screen turns black
and up in the top left side of the screen is HBMI 1 , sound stays on when it does this. Some times it looks like the screen is pulsing then goes black. Then it comes right back on and all is fine. This may happen 3 - 4 times in a minute then its OK for a bit.
I have tried bypassing the receiver and it still happens. I've tried different combinations but still does the same thing. tighten all the coaxial cable from the dish to the receiver.
The HDMI cable to the TV is a Bell cable that came with the box.
The TV is a Sony KDL 70R550A , Receiver Yamaha RX-V575 and the Bell HD box 9241.
Any help would be appreciated
