Samsung LE40R88BU/XEU 40" LCD TV

[WADEREK]

Hello, can anyone help me with a Samsung LE40R88BU/XEU. The set came in tripping, so I went straight to the PSU caps, which were swollen, and replaced them, switched on, no change. I then replaced the PSU with a spare, no change, then the inverter, still the same. So I checked the output voltages, which seem to be ok, untill the psu trips. I notice that there is no display or voltage at the inverter output at any time. Can anyone help?
Derek.
