I was given this defective LCD TV. It had no working backlight. I located a faulty transformer, one of 8, and replaced it. Backlight is working now.
However, the only way to get colour is when I use the component inputs. I don't believe the 2 faults are connected, in fact I don't even know if the colour problem could be fixed by setup. I got no service manual.
Has anyone out there an idea where I could start?
Cheers
Tony PS:(I am running the unit on an temporary PSU. The original PSU was missing (24V 6A) and the one I ordered on eBay (China)had the 4 pins wrongly connected, believe it or not! Rotated by 90 deg. Lucky it just shorted and didn't reverse the voltage...)
