No video but sound ok

My Westinghouse Roku TV display just randomly stopped working. Sound is ok as I can hear the menu change when I use the remote. Right before netflix was being buggy so I turned it off then on and it was fine until it just went black. 

Since then I’ve turned it off and on, plugged it out, pressed the power button for a minute and restarted it using the remote. Every time it comes back on the display is black then it fades into vertical boxes that range from black to white. Seems the longer the tv is on the whiter the boxes get. 

please help! I just bought this TV a few months ago.
