Trying to get my dynex tv to turn on

[Treyminator]

How do I get my dunes tv to turn on, I've had it for almost 2 years now and when I press the power button the green light comes on but then the screen flashes and it changes back to orange I've been able to turn it on recently after about 30 mins of pressing the button

This happens when the power or system boards starts to go, it can take a long time to turn on. For a Dynex set, it's probably cheaper to replace it with a new or used working set then pay someone to repair it, unless you want to try to buy a system board and swap it yourself. Issue may end being not the board though, would be simpler to replace it.
