Hi
Got this Onn tv and found that 3 caps were fluffed in PSU and all the caps were bulging on both the slave and master boards.

Replaced all caps and now found that the tv makes a clicking noise to start up a blue led comes on the master inverter for about 2 seconds then fades....no backlights at all not even a flash and then die again...all voltages seem ok to inverters...23.7v

Anyone come across these inverters for faults, part numbers

Master: 6632L-0448A
Slave: 6632L0449A

Thanks in advance
