Question about Televison & Video
You didn't mentioned the brand and model number of the tv. Any way from its appearance i think its Pioneer Plasma tv. As you says you are facing this problem every day , There is some problem with the Power supply of the Plasma monitor. Probably the electrolytic
capacitors. After a long period of use may electrolytic capacitors can become bad by the heat produced by the nearby components. The bad electrolytic capacitors in the power supply can create such problems in Plasma tvs and also in Lcd tvs.
Working in the power supply of plasma tv is a skilled work. Not only the power supply of the plasma, Power supply of all the electronic equipment should be repaired by a person who has well knowledge in electronics. Because the is risk of electric shock Even if the power is removed. Because some of the electrolytic capacitors in the power supply will hold a DC charge for more than one day. This Dc charge is more lethal than the mains AC charge. If you think that you can go trough the power supply and is able to replace the capacitors with out making any harm to yourself then inform me the same with the exact brand and model number of the tv that you have. I will try to assist you to solve the problem that you are facing

I bought one of these tv's at a thrift store and it had the same problem, orange light blinking and static sound coming out of the speakers, no video at all.
The problem was the power supply board, this power supply has multiple outputs that feed the circuitry, 12V, 24v, 5V.
There was nine electrolitic capacitors I had to replace to fix it, all of them were bulged they are easy to spot, I measure one of them that was supposed to measure 1000uF but measured only 65uF. you can buy these from digikey for about 50 cents each, they need to be rated at 105 deg c and the profile has to be below the heat sink otherwise they will hit the top of the heat sink, the spacing between the leads has to be 5mm so they fit in the pcb. I replaced 3 1000uF/25v, 3 470uF/16v and 3 1000uF/16v and that fixed the problem, I bought this tv broken for 100 bucks fixed it with 6 bucks.
Good luck, don't perform repair if you are not familiar with dangerous AC voltage inside the TV.

The tv has an internal safety switch that turn tv off when there is a short, overheating or overvoltage. This is often caused by a bad capacitor, bad cold joint or faulty IC.
Try first unplugging tv from power cable for 15 minutes or so, so to reset it, sometimes this fix the problem.
If this did not work, to find the cause of the problem you need to have a technician testing components inside tv.
You find the phone number for repair service printed on last pages of tv owner manual, also check your guaranty terms.
