My LG42N5700 SMART 120hz LED HDTV was purchased in 11/2013. Worked fine until yesterday. Now cycles on/off in about 3-5 second intervals. Only way to stop that is to unplug. What's going on??
JA: I'm good. And you?
Customer: Yes, I'm fine. Can you help me? Can this be fixed?
JA: Just to clarify, what's the HDTV's exact make and model?
Customer: Receipt says LG 42LN5700 Smart 120hz LED HDTV and it also has 3D.
JA: Does the TV menu work? Do you have the same problem on all sources/inputs?
Customer: The set will not stay on long enough to change the channel. Have changed batteries in the remote. Have tried using the controls on the side of the TV, all to no avail.
JA: How long has this been an issue? What happened right before this popped up?
Customer: The set was on Netflix yesterday for about 2 hrs with no trouble. Switched to local channels using antenna
, OK for about 30 mins. Began to cycle on/off in about 3-5 second intervals. I was unable to turn the TV off using the remote or side control. I turned off all power to all the electronics associated with the TV. Same problem when it was repowered. When power is re established, the set comes on (with out using a control) and then cycles on and off over and over
JA: Is there anything else the TV Technician should be aware of?
Customer: Ask me some questions. I think I have told you everything.
