The tv works fine when started works for awhile then the screen goes black and the power button flashes green 20 times. It comes back on works for awhile then the screen goes black and flashes green again. I have had the LIFi bulb go before and it presents itself differently plus it does not come back on. It seems to be happening more often now, does anyone know what might be causing the issue. I have contacted a few repair places and they seem to be baffled. In the manual under troubleshooting error codes only explain red and orange flashes of the power button. Thank you in advance if you can be of assistance
