I have a GV47L FHDTV, purchased in 2009. Never had a problem, but yesterday, when I turned it on, the picture brightness was half normal and it was flickering with dark horizontal lines. I only use HDMI
inputs. Checked the connections on all. Each input shows the same problem. I isolated the inputs and disconnected each in turn, same thing. I've tried everything I know. Any ideas?
JA: What's the exact make and model of your television? And have you done any troubleshooting yourself?
Customer: GV47L FHDTV. Refer to the last message for troubleshooting.
JA: Does the TV menu work? Do you have the same problem on all sources/inputs?
JA: How long has this been an issue? What happened right before this popped up?
Customer: 2 days. As far as I know the previous night everything was fine. Next day it was just there. No thunderstorms or any other disturbances.
JA: Anything else you want the TV expert to know before I connect you?
