Sometimes you will need to reinforce the whole circuit with new soldering metal as well. Mass produced circuitry sometimes uses very little of the stuff or uses soldering metal of poor quality.

Lg 563n horizontal driver transistor overheats and get shorted after a few hours or in a couple of days


Look for bad solder connections in the horizontal drive circuit, especially at the horizontal drive transformer and any capacitors in the area. Ring cracks around the transformer leads are common and cause the drive signal to distort. You may also want to check the values of any tuning capacitors in the drive circuit. I've never worked on one of these so I can't give specific parts to check, but I've seen these troubles in many TVs and monitors.

Width of picture increase


Have you checked your display adapter settings? Check the display settings in control panel. Make sure you are viewing the screen at a decent resolution. 800/600 or larger. Let me know what happens. Good Luck, Tim
