Dear munu007 good morning this is viswanath
Don't worry I can salove UR problem
1.First U can check any physical damage in power supply (220/400v)Main capacitor,
2.And also check LOT It's OK Than Remove H O/p Transister, check SMPS output voltages ,voltages are currect That means SMPS is OK.Check Boosting FET IRF630(Q402)Change it New One,and also change the IC604 7805 Regulator.
Finally change LOT.
check any dry points (SMPS&Hori.)
