I have Samsung UN40F6400, which was reboots continuously and opened the TV and checked for loose connection - disconnect and reconnect all cables.
When I power ON and noticed that its entered into Burn mode (RED/GREEN/BLUE) screen and I turned off and checked the cables again but this time it turned into white screen only. No matter how many times I restart the TV the result is same. Below are the Voltage measurement in T-Con Model: BN41-01939B.
Needed your expert advise, whether it is the TCON faulty or Total Panel Failure??
TCON LED status: All 3 Blue are ON.
