I see the lines with the menu on or off. Does this mean it is the digital board? What does that cost? and how easy is it to replace?
What brand is you TV?
And i need to know 2 thing.... possible one of the 2 is the problem.
first try to display your tv menu and let me know if you can see it ?
and if you do it and you cant its the DMD boar..
if you can so its the digital board and you need to replace it..
keep me in touch...
