Plug an HDMI cable on it and connect it to your tv, if it's hd...if it desplays the screen on the tv, the board is ok and the problem is either the screen is burned out or the cable connecting the board and screen is damaged. I had this probl and around 5 kilo, they told me they will charge 3500 if it's the screen and 1600 if it's the cable...Lela bota alteyekum I am sure yeteshale waga yinoral
