Good luck on that monitor. It was manufactured for Dish by Thomson/RCA. I bought one of those and out of the box the picture was squished on one side. It sat in a repair shop for many months waiting for a voltage transformer that ended up not being available anymore at that time. The repair techs said a lot of those sets were failing and the voltage transformer is the most common problem.
