Some el.components are loose on tv circuit board.I have removed the back cover,supported tv picture tube 45 deg.against wall.This tv is heavy!One screw on left holds the circuit board to bottom case.Removed and supported this board on few heavy books.Turned tv on and gently probed all the componets on top of the board with plastic drinking straw.In my case transistors Q-830 and Q-421 needed resolder loose joints.These components are mounted on flat aluminium heat sink strips located sligtly left of center of the circuit board.Also blobed bit of silicone into base hole and foot of alu.heat sink to support it.
no rocket science here - my son fiddled with the cable cord attachment, until presto, the screen became sharp. Then we moved away as fast as possible, lest we shifted it and it put us back at square one.!!
I should mention, however, that if it's connected to cable (or certain satellite services), you won't need a converter to watch the TV - you'll receive the digital signal (although you won't have the 1080-pixel HD resolution - the 36A50 only has 850 lines of resolution).
I hope this helps. Please let me know if I can be of any further assistance. H2H
