What can I do to fix this problem with this sceptre tv?
Our tv went out about a month ago and wouldn't even recieve power. We were waiting for parts from the Sceptre comapny to replace out main board and our power board. Now that I've replaced everything and put the parts in the tv turns on but and have a black screen but without an actual picture.
