Hello, my Sharp Aquos LC-50LB370U TV stays without a picture when I turn it on, however, the indicator light still works but is blinking. Can you help me please?

    Hello,
    It's the power supply board that needs to be replaced. You need to remove the back cover of the TV and install the new power supply board; it's fairly simple to do.
    You can also try to repair it; check the capacitors to see if they are swollen on top, indicating that they are faulty.
