Hi, Power supply blow the main input fuse that tell you the main Switching IC or transistor shorted,
first of all should get the service manual, but many service manual don't include schematic for power supply unit, but you can get the parts number for it and go on line to find out who have it. Or you can find out what IC number is for it, Is it available online shopping.
Power supply is the most easy fix portion of LCD TV. |
