MY GTMEDIA V7PRO DON'T WORK

[vgmediac]

Hi,
my GTMEDIA V7PRO don't work. Model P30M3ST-1 series V7PR2105023053.I turn it on, with the remote control the LED from red turns green, the connections are as per the user manual. With the remote control I press the menu button, but the GTMEDIA does not give signs of life. The GTMEDIA video features boot, load then 4 dashes. What is it? Who can help me??? Greetings and thanks.
