this TV is just over 2 years old. the insides look new. but when you turn the tv on the screen gives you a little glow but no picture or sound is heard. If you hit menu there is no OSD. as I have looked on the net I have seen people talk about voltage regulators on the main board having issues. I need to find a service manual or schematic for this tv if anyone could help with that. thanks.

I purchased a main video board and to my disapointment it did not fix this issue. so then I purchase the T-Con or LCD controller board. YEA!!! that fixed the tv and now it is working great. I hope this help someone.
