Turns on but doesn't do anything else. Screen doesn't come on. Can hear a clicking sounds like a turn signal sound.

1-check the vent door actuator while you turning the knob from the (vent/defrost/floor) if its not changing the directions and you hear clanking or plastic gear rubbing ..then that's the actuator broken 2-turn the knob again same above and if you don't hear the sound of the actuator ..then you have the climate control unit is defected if its Digital control unit .

Right-click the speaker icon in the Notification area and look at all Playback settings; some settings might be muted, or not selected. There might be two speaker icons if you're running special software for the soundcard.

Hello, Sounds like internal malfunction, needs to be checked by service tech.

key question is does power light come on and or stay on or not?

Send your tv back for professional repairs as this is the first sign of failing LED's somewhere in your tv. I hope this helps

Hello sorry to hear that. From your description it sounds like your signal board may have been damaged by you plugging in your laptop to it. The signal board is the one with the tuner on it.

It sure could be. But, first...by "won't turn over" you do mean it cranks at normal speed but won't start?
A simple test of the fuel pump is to stand by tank and listen as someone turns key to on. When first turned to on, your pump will activate for 2 or 3 seconds, pressurizing the fuel system, and then shut off if the engine computer doesn't get a cranking signal. Do you hear it come on? If not, then something's not turning your pump on. If you can hear it buzz on briefly, then maybe it's your filter. Another test: Spray a little starting fluid into your intake manifold (remove the big hose going into intake manifold) while someone tries starting it.If it doesn't fire and try to stay running, then it's probably an ignition problem. But if it does fire off, then you know it's a fuel problem-likely your pump or filter. good luck.

There is no sound touching icons. Never has been. There is only sound sliding the lock unless someone turns it off.
As for the lock not working. Chances are your screen is malfuncitoning

The problem is most likely a warped plastic housing around the color wheel. When the wheel is forced to stop, the projector will go to standby and the lights indicate a problem.

It means your hard drive has failed. you will need to install a new hard drive and reload your operating system.
