Reply To: REPAIR ADVICES AND HELP FOR BROKEN OSSC 1.6
Since it is difficult to access this part quickly where I live, I tried to short-circuit it temporarily, still no image…
edit: when i do this short, u3 becomes very hot. That’s why I think that u3 may have burned out on the first try because excessive current was drawn from the 5v line. That’s probably why f2 is getting fried. In this case, how can I tell if the U3 I have soldered is defective? Does the fact that the menus are working and communicating indicate that the chip is completely healthy? Or could the hdmi out tmds output stage be defective, although the side of the u3 encoder facing the FPGA is intact? I have another brand new it6613, but I don’t want to ruin it like this. What should I check in the circuit for this? What could be the source of this problem of overheating u3 and burning F2 by drawing high current?
