SOURCE: RCA Big Screen Turns off
This is a shutdown circuit problem, I would suggest that you send it to atv shop, or find a shop on FixYa.com to look at this for you. I have fixed problems like this in my shop, but I always require the customer for pay a schematic and a exploratory fee prior to me starting the job, other shops may or may not do this, so shop around first.
SOURCE: auto focus problem
The auto focus is not actually focusing the tv. When it is running it is adjusting the convergence. Most likely the repairman that replaced your tuner didn't plug the sensor wires back in. I would call him back out and have him hook it back up.
There should be a convergence menu in the tv. Use the samsung remote and go into the menu and look for convergence.
