One half of picture is distorted


to create the total geometry in the tv is needed a system called Convergence.Convergence amplifiers are damaged in this unit, magic focus cannot work because magic focus works to level computer and controls the amplifiers damaged. this repair is for a technician because an adjustment is needed after the amplifier's replacement.

Samsung rear projection tv has multiple images with differnet colors


The auto self focus screws up if the picture does not remain constant or close to it while focusing. It is designed to self focus every fifteen minutes. Go to menu and then setup and turn the auto focus feature off. I have had mine off for the past year and have had no problems. If you slide the bottom portion of the remote down you will see a self focus button. My suggestion is to put a DVD in and hit the pause button during a scene and then hit the self focus button. It should align back up and may take a couple of tries. (If you have an aftermarket remote, just enter the menu and then setup and you can activate the self focus feature, just don't turn it to auto focus!)

Rca tv picture blurry and arched up at bottom


Replace the Sanyo I.C. chip on the heat sink of the power supply convergence board STK730-XXX. Last 3 could be 130/010/020, any will work.
