Recently while watching tv there was a loud pop and the screen went black and then turned back on. After this happend I noticed my menu would not pop up I couldnt see what channel I was on and the volume meter has dissapeared. The popping sound has happend 3 times seperatly and has not done it since.I want to get hd cable but I was told I have to change the tv from 480 to 1080 in the menu screen, which poses a problem since I cannot see it.The tv is a rear projection and hd capable. Ive had it for about 4 years. Any help would be greatly appreciated.
Take your set to a tech the tv system control circuit might have damage, that circuit controls OSD,channel memory. it is an ic that controls that circuit along with other components.good luck.
