Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time.

Turns on but doesn't do anything else. Screen doesn't come on. Can hear a clicking sounds like a turn signal sound.
looks like a( DLP) tv digital light proccessor . aka projection. most likely the bulb is burned out . if so cost is $65-125 bucks. aftermarket bulbs are available online but some dont work or burn out prematurely. if you decide to fix it or buy a new tv ,invest in a surge protector. it will save your tv from problems like this . good luck.

Turn on but remote doesn't work
I would try new batteries first. If that doesn't help then replace the remote with a universal unit that you can program to work with your TV.

THE T V WILL NOT POWER ON
plug the cord into the outlet. If the wall outlet doesn't work find a different one. If the tv doesn't turn on with the remote take the plastic off of the batteries in the remote. if this all doesn't work, then there's something wrong with the tv and you should return it and get a new one.

When I turn on my set, light turns green, then after 30 seconds turns red won't come on
Sounds like there is a problem with the power supply. Try unplugging the T.V. and hold the power button for 30 seconds. Plug the T.V. back in and see if that helps. If it doesn't try switching to another outlet, and if that doesn't work then you may need to replace the power supply which would probably cost anywhere from 140 to 200 for one.

Unplug the set and hold the power button for 30 seconds. Plug it back in and see if that fixes it. If it doesn't then it sounds like there is a problem on the board underneath the power button. Something isn't allowing the circuit to be cut.
