I can't tell you if the three flashes identify the problem better but it is with fair certainty a power supply failure. It may be the main power supply or a separate board that produces the high voltage required by the plasma display.
Typically, the parts cost will not be high but the labor may run it up.

When turned on, no picture, sound or response. LED is OK


I had a similar problem with my HANNSLounge 32", the screen switched on with green light but none of the front panel buttons worked (screen is black apart from showing the input source in the top left).
After powering off numerous times I tried starting up with a blank SD card in the reader and the tv cycled between red green and blue screens and then reset itself. (Some sort of firmware restore?) After which point I had a working screen again! (Will have to see how long it lasts for!)

TV not turning on.


Mine was doing that and I ordered a replacement power supply board for it and now it work. It's fairly easy to replace.
