SOURCE: screen removal
pop off the front cove were the speakers are grab each side just under the screen were it is seperated. and it will pull right off. then their are two screws holding it in place on the bottom corners. after screws are removed the screen slides up to unhook.

The clicking noise that you are hearing is actually the power relay. Normal operation by either the remote or the power button on the front panel, you would normally hear a soft click just after the press of the power buttons to turn the unit on or off. When you initially plug the unit in to power, you will hear the same click noise. Being that you are hearing it all the time indicates a failed relay. TV's now a days, or at least ones built during the last 15 - 20 years have different Printed Circuit Boards (PCB). There are PCB's for power (which youre dealing with now), sound,video and so on. The PCB that you need to repair your clicking issue will run you about 80 U.S. dollars for the part plus the average going rate for repair from a qualified service tech. You could purchase the part from Thompson Consumer Products repair and fix it yourself, but be aware, there will be no warranty on the part itself unless an authorized tech does the work. Located on this PCB is the power on/off relay, fuse, usually 4-5 connectors for power to different PCB's (depending on model and features). Now depending on how old the TV actually is, you may want to invest in a newr set, the reason why I say that is, is because the new power unit may and can overload the other boards and cause damage to them and now you have a new problem to deal with( along with more money being tossed down a hole.
Good luck
