Plasma TV's are notorious for power supply problems, its most likely failing capacitors in the power supply. If you can find a repair shop i would take it in, otherwise you might also be able to find a replacement power supply board online, but its a crapshoot to find a good one so its better to try and repair/rebuild the one you have. If all else fails its just time for a new TV. It sucks, i know, but i see so many 2-3 year old TV's failing its like a plague of the repair shop.

I have seen similar problems (features?) with Syntax LCD TVs. One thing to try is to make sure that the backlight brightness is set to its highest setting. On my Syntax, when this is set to a darker setting, it produces annoying hum through the speakers. Mine also is smart about turning *off* the audio amplifier when set to zero (or mute), which sounds like the behavior you are describing.

If you wish to buy its original remote control, contact the authorized service centre, or authorized dealer to your device brand. They can either give you a genuine remote control to your device, or can direct you, from where can you purchase a suitable one.
To select a proper universal remote control, you should know about the number of digits to its set-up codes. There are 3 digit, 4 digit, 5 digit, 2 digit and even single digit codes, to some brand devices. After confirming this, check the sites linked here. Both the sites have set-up code list and set-up procedure to many popular brand remote controls. Check which brand remote control has set-up code/s to your device brand, and buy that one according to availability. Brand name of the remote control isn't a matter, but it should have set-up codes in its code list, to the device brand you have.
Please note: Every new universal remote control will have set-up code list, and set-up procedure along with its pack. Never accept a remote control, that hasn't both of this. For more details about the set-up codes, visit the sites.
Universal remote controls are available at most of the electronic spare part selling shops. Visit some on-line sites too, which deals with electronic spare parts.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here.

It sounds not a switch fault. It should be the fault with its main power supply regulator board itself. Its start voltage will not be proper. Contact any service technician.

Dim the lights in the room. Turn on the set, does it go from a black screen to a light gray screen? If not, your panel isn't being primed and is most likely caused by a defective Y Sustain board.

That is probably the cable's fault. Disconnect the cable and reconnect it, both on whatever it is connected to, and in the TV.

if it has a burned image/s on the screen they cannot be removed, use set and ignore those, cost for replacing the screen unit is more than a new set.

Ten years is two lifetimes for a Plasma, it most likely is either the display panel itself or a main board, in either case not cost effective to repair or smart but the real problem would be parts, I bet almost zero is available for this.
