I am having trouble with my Daewoo TV. The Model # is DTQ-19P3FC COLOR TV-VHF/VHF it was manufactured May of year 2000. the problem is that it was working fine but when I turned it off it wouldn't come back on. I have left it unplugged for a day, I have been manually turning it on as well as using a remote and its still not working. Please is there any way That I can fix this problem myself without having to take it to the repair shop. thank you
