First of all it's not a television problem because the nintendo wii u is working fine and that's connected via HDMI and i tested all my HDMI cables and they are working fine as well.I tested all the HDMI ports on the tv and they are working fine with my other electronical equipment.When i turn on my playstation 3 the HDMI port that it is connected to on my tele becomes an active outlet on my tv source menu.However instead of getting an actual screen i get a screen with a no signal sign instead.Is it possible to fix a PS3 HDMI port?
