try to reconnect all connectors inside your TV,if the problem persisted try to check the power supply output 15vdc while the TV is on..Let me know what is the reading of 15v output..you need a multimeter tester (range in dc)..Also trace the board where the 15vdc connected and try to disconnect the supply to it then check again if the voltage stable for 15vdc..

Thank you for using fixya..

chester
