Problems with sound, video , and powering on

It sounds like a wire is having problems inside the TV itself for the power to the panel. The clicking you hear is probably sparks inside the TV of the cable having problems. Please open the TV up and check the cables going to the panel.

Its the power supply not to exspensife to fix do you hear a click and the red led display light come on

I believe the sound you hear is simple static, if there are no power buttons showering where they should, look for a bad power adapter, make sure it is on, see a light? next check your battery.
Now past this you have a problem inside of your laptop, as in a bad motherboard or bad video chip....

Now tv turn on have power LED and OPC LED lights indications flashes together?Yes,this problems,it is the tv Tuner signal board it is causes and the problems.That the board where the incomming broadcasting signal cable plug into it.If turn tv on.No power LED light or any kind LED lights at all.Yes.Than the tv power supply board that the cause and the problems,that the board where the tv power a/c cord plug into it.U have some basic mechanicals skills like take things aparts and putting it back together again?Yes,tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish tv Tuner signal board or tv power supply board for the replacement.

First thing to try is a video reset.

While the PS3 is off (red solid light) hold down the power button until you hear the SECOND beep, quickly release the power button.

Let me know what happens.

check your screen back Light or get a working screen and test it or your screen flax is bad

Your tv screen has problems with the video mode
that has setted up on your ps3, hold the power button till hear two beeps, this will reset the video mode of the ps3, and leavse you at a screen to set up the video mode of the ps3.

Succes.
