I couldn't get any video output so I decided to update BIOS version to 0047. I have tried 2 different ways: pressing power button and removing jumper. I followed the instructions, but I don't know if the update has been completed successfully because I'm not still able to see any video output on my TV. After rebooting, the situation is the same.
How can I know the BIOS update was done ok if I can't see anything?
Thanks so much for your support
