I am designing a shunt regulator which regulates the power from the solar panels. The power that is required by the loads is transferred from the solar panels to the loads and the extra power is dissipated through the shunt regulator unit. The circuit diagram is attached.
I have recently acquired a faulty LCD TV that does not power on. I popped oven the back cover and tested the fuse on the switching power supply board which was blown. I then replaced the fuse however it went straight away as soon as the power was switched on from the wall.
