hi to everyone, i am a newbie to this website and i need some help.. i ve bought a bios free zone from bad_ad84, and it is not working, all i have is a black screen. i followed the tutorial very well, i triple checked with a magnifier my soldering, no trace broken, checked with multimeter all legs and traces, connections to other chip, points on main board and i can fairly say all i good no mistake from me... the motherboard is 171 - 7069b main 837-11892-01 pal... do you know if there is any issue with the bios free zone and this model? it seems some french people are having the same issue with this main board.. coincidence? I did the 50/60 hertz switch before that and didn t have any trouble. hope anyone can give me a hand! thanks a lot.
Modded many VA1 boards, PAL and NTSC. Every single "My soldering is fine" issue I have had, have all been soldering issues. Send me just the motherboard and cover return postage and I will look at it for free. Just because if I get it working, I can send this thread to others who have issues.
I'm betting on soldering issues myself, not seen any problems with swapping out the BIOS that could be tracked back to the BIOS itself. Usually is a problem in the waiting that removing the board and handling it causes to crop up.
