It is a 32 inch Smart tv of the ken brown brand. The model is kb-32-2260. The problem is that when you press the power button the TV starts normal marked "please wait ..." but after that phrase it turns black and 10 seconds later it turns off. Has anyone had a similar problem? Do you know what the problem would be? I tried to try reinstalling the firmware but I couldn't find it, if anyone has it please pass me the Link. Thank you
