Re: [Philips TV] 47PFL5604H backlight/inverter
Remove those suspect diodes that show bad in the circuit and test them off the board.
It sounds like the SMPS is cycling on and off which can be due to shorted circuit or bad startup/running cap.
Please upload the pictures of YOUR board also.
Is this the same EXACT board as OP?
