Okay he's got a JVC IART Pro AV-36P902 TV
http://www.avguide.com/products/product-2064/
It's hooked up to a receiver.
When you change the input on the receiver it's blank. There is sound, but no picture. So playing DVD works, playing Digital cable doesn't, and playing N64 does the same thing.
Now in order to see if it was the receiver, another TV was hooked up and it worked fine.
So, when you change the input on the receiver the TV doesn't seem to get that it's not changing.
Any ideas/suggestions?
Thanks
