Title: LG 32LC46
Post by: stellaman on March 30, 2010,06:39:35

Can anyone help please.This TV switches on LED flashes green,backlight comes on then get a buzz from top of inverter PCB, then no pic or sound but green light on. I know there is an LG mod requiring the removal of coils etc. but this board must be a later version as this has already been done.Any help appreciated. Thanks, Dave
