After several hours of troubleshooting, found the tuner to have bad 
connections. Removed and soldered
inside the tuner.
Thanks to Joe Searles, Gary M.and everyone else for their help and Russ Gray 
for sending me a print.

Set has chassis A8S81200
I ruled the tuner out, but do not have a schematic.
A/V inputs produce good video.
If I disconnect the tuner and input a signal, I still don't get anything.
As I was looking for bad connection, found PCB cut on IC101 pin 10/11. This 
appears to be intentional, so
I don't know if another shop did this as a modification.
I repaired the trace, but still no video.
This set came in with a bad flyback, I tested it fine, but when I turned it on 
today, found this problem.
Any ideas?
Thank you.
