    So, Update !
    I found the 1.6 pcb schematics, it helped me follow the 3.3V line.
    So I sat down a little more and by testing, I thought the C18 capacitor was shorted
    After removing it and feeding (temporarly) U5 into U6 (which was previously removed) I can get the OSSC to boot and display the usual menu on the LCD.

    BUT, I get no HDMI output (not even the test pattern), and even if I plug any cable, SCART RGB or Component, the OSCC still displays “NO SYNC”

    So maybe U1 and/or U3 is definitively fried, or maybe there is another faulty capacitor / voltage regulator ? Or maybe somehow the whole board is cooked ? x)

    Other regulators seems to output the right voltage.
    Could it be a shorted clock or sync line, something like that ? It may explain the sync problem for the input and output ? How could I debug this ?

    Stay tuned
