Hi! I have a Matsui ( Proline ) All of a sudden it won't turn on. When I press power button either from the TV/remote, the only thing it does is green light comes on and post the" Matsui" logo and then will go blank black. And does not receive commands from the TV buttons/remote. I tried updating the firmware through a USB stick, the USB stick lights on when I attached it but nothing is showing on the TV. I tried detaching all the connected devices and unplugging it but nothing happens.I have replaced the Power Supply Board, still doesn't work.
What could be the problem?, is it worth trying to repair, or just replace. Your help would be greatly appreciated. Thank you very much.
