When you switch on the tv the sound will be heard but the tv screen will be blank and when this happen it is always linked to the inverter board.
Its a 22inch tv and supply to the inverter board is 12v.I want to change this board but decide to check maybe I can fix the board ,its a small board of 4ports.
I check supply to inverter ic and its zero
I trace to the voltage input terminal it was 12v but the smd fuse is bad. I solder a strand of flexible wire to re-fuse it and powered the tv.It worked perfectly its just the fuse that broke that caused the problem.

I hope you used a very thin strand of wire unless you want fireworks in the back of your tv instead of on the screen! Lol
