http://nfggames.com/forum2/index.php?topic=5803.0 I have 4 controller with this, to put it simply the result is amazing. The only problem is...
Thanks for having a look, I should have mentioned that this is a picture that I found online, I haven't taken a picture of my actual board yet, I...
Yeah it seems to power up fine, the light comes on and the TV automatically switches to the correct SCART channel. The power adapter works for my...
Hello, I've been trying to fix this megadrive 2 for a while now (Christmas present for a friend hopefully), it will power up but will not show a...
I can find 2 rectifier diodes on the heatsink: FCH06A10: Not leaking current, reads 5.3 KOhms across the diode on both sides when conducting....
Okay, got the capacitors all replaced and tried the board separate from the console, it's still making that whining noise but the 5V and 12V lines...
This may sound strange but it helped me, will the noise stop if the system is upside down horizontally?
I'm getting 1.5 Mega Ohms between 12V and ground, I'm guessing that's a bit high? Also, I lost my piece of paper where I'd written down the...
I'm getting around 660 Ohms from 5V to ground pins, 1000 Ohms between 3.3V and ground and no connection between 12V and ground. So that could be...
I would if I knew anyone else with a DC EDIT: Misread your last post, you're suggesting I check the power pins on the DC side without the PSU...
I'm measuring the transistor out of the circuit, aren't they meant to be roughly the same when measured on both sides? I'm getting about 0.4V on...
Well I was just testing the rectifier diodes and the transistors, I'm getting an uneven reading (25% lower resistance from one side) on the D1276...
If the shorting were to happen external to the power supply wouldn't the power light still be on and the PSU supply the correct voltages?
No VGA box for me, RGB scart lead. Was yours 240V as well? And did you manage to repair it?
I kept the plastic in place :) It is the 240V PSU, are the caps a known issue with this board? I'll try replacing the caps and then if that...
So after finally obtaining the new GD laser for my dreamcast I plug it all in and the system just dies on me, the PSU has started making a...
Yeah I was worried that I may have burnt it out, I did go in very small increments though so there was maybe something else broken anyway. I've...
This is the exact problem that my Saturn had, the fix worked perfectly. Thanks man, if you hadn't recorded what you did in such detail I'd...
Ah right, I've been testing the traces from the Z80 to the other chips, I've managed to confirm that half of them are working, however it's a...
Sorry, I'm losing track of you here. From what I have read, if I just replace the bios with the diagnostic bios I can test the main MVS board...
