LG Plasma No signal!
I am extremely aggravated and looking for some help. I bought a LG 42" Plasma TV used, got home connected and everything was working fine. A few hours later the signal went out so i disconnected and connected it somewhere else. Now I get sound but no signal, the TV is connect via HDMI and no luck with cable box or PS3. If I connect RCA cable or red white and yellow it works just fine! Has anyone encounter this or has any idea of what could be wrong?
Any help will be greatly appreciated. Thanks!
