Title: LG42LG3000 LD84A Chassis
Post by: stephenjames on February 03, 2011,15:53:12

LG42LG3000 power up and red led appears.Switch on via front panel switch or remote control and led flashes 3 times then backlight switches on for around two seconds,backlight then off and blue led appears and stays on.All voltages appear to be normal.Have tried replacing slave and master inverters to no avail.I am beginning to think i may have possible ccfl problems.Any body seen this before?

                                                    Kind Regards

Hi Steve,
What power supply does this set have, any reference code, most of the LG's I've worked on have psu electrolitic problems, bulging. Check download area there is a schematic for your chasis.
