training.av:
check power supplay of tv set for correct output voltage, some filter may be found burst defective(1000mfs/25v), causing higher +b voltages.
 after correcting the smps voltages, make sure to reset the tv in menu
 the fault will be resolved. also check LVDS Connector for proper fitting.
