Decoding "Screen Bypassing": The Holy Grail of TV Repair
-
In the case on his bench, he opened the T-con and discovered a cracked solder joint on a decoupling capacitor and a hairline fracture in a PCB trace where a screw had stressed the board over the years. With a microscope, he reflowed the joint, bridged the trace with a thin wire, and reseated the ribbon cable. He tested the TV—first power, then backlight, then full-screen patterns. The image returned, colors stable, bands gone. Master’s LCD LED TV Repairing and Screen Bypassing
