Having problems with your Flat Panel Televisions ?

I have A Samsung 52 inch LCD TV model #LN52A580P6FXZA. The relay clicks at A random rate, there is A red light that flashes steady. It will not power up. All my standby voltages coming from the power supply are present as well as the run voltages. Power supply on voltage is present, inverter on voltage is present, occasionally, it will give A loud high pitched squeal. It never comes on. Any help would be appreciated.

I have a Samsung LN46A530 46" LCD TV. Lost my backlight and wondering if the two wire connectors feeding the R and L inverters is where I would meter for power, and if not what are these for ? Or is it the ribbon cable on the top left (it's pin ids are 1. 12v_cold, 2.FB, 3.FB, 4.GND, 5.GND, 6.LD, 7.LD). Would this TV use 12 V to power the inverters ??. The inverter enable is on (5V), so I assume it is either the pwr supply or the master inverter.
