If you can open than open your LCD tv & checked Inverter Borad it have White & red color connector may be this board is defective.

This Proscan 19LA25Q has no relay to make any clicking sound that I can think off. The common problem with this model is the fail backlight inverter board. Did you see the screen flashes on for a second? You should also check the output voltage of the AC adapter, it should be 12vdc with load. Check the surface mounted fuse on the inverter board (this board is really hard to find).

SOURCE: I have a 47" Proscan
Right now the standby 5vdc power supply for the processor on the main board is working (the standby power supply and the processor are running 24/7, even when the TV is OFF) but nothing else, and since you cannot even turn on the TV at the TV control panel it may mean that the main board is not functioning.
I would inspect the power supply module first though just to make sure it does not have any bad caps, burnt parts since bad DC can make the TV to have strange symptom.
Please read my guides first to understand more.
