The tv was working fine for years on HD CVI mode where we watch our AT&T U-Verse. Then I hooked my laptop to the HDMI port and it worked well for about 15 min then the tv went blank and showed weak signal on the screen. I then unplugged my laptop and the HDMI cord from the tv. Then I unplugged the TV to restart it.
When I try to watch AT&T U-Verse on HD CVI mode the tv blacks out and shows weak signal on the screen.
Did plugging a device into HDMI somehow change the settings on my tv?
If so how am I supposed to get rid of the weak signal sign so I can watch tv again?
Again it worked fine before I plugged my laptop into the HDMI port.
Help please???????????
