I checked the boot rom socket and that seems to be fine. Do have the security chip in (G45-US-U)
Put the video card in a computer (windows 7) and detects as Standard VGA Graphics Adapter, but say "This device cannot start. (Code 10)"
Checked the and it looks good. Nothing damaged or corroded. Gave a little touch up on the solder just in case.
Xilinx chip has a little gunk on some legs, cleaned it up a little. Checked the legs on all the surface mounted chips and didn't see any broken or damaged on them.
What one is the...
Recently got a Golden Tee Fore 2005 and having some issues.
It's a green board Model #2011; P/N: 2011 REV6; BIOS V1.06
When you turn it on Status 1 (D20) is solid, Status 2 (D5A) blinks and D75, D76, D77 are all solid red. There is no video output at all.
I was told the wiring was disconnect...
Thanks for the info on the Mask roms. Interesting stuff.
With D18 it says 1M-8bit, but not JEDEC I would take it that it would have a different pin out then the standard?
I have one op-amp I think might be bad. Test the inputs have voltage, but the output is a constant 0v. Unfortunately I in...
I can make another video with a more clear audio of it.
It kind of sounds like they are distorted. the noises seem to be there but get kind of high pitched, garbled and then sometime seems like it just stops playing the sound or goes quiet.
When it comes to the mask roms like D18, how do you...
Revisiting a sound issue that I was trying to fix a year ago, but had to unfortunately stop and now looking to find the issue again.
The Game plays fine just has a issue with some of the sounds. In the sound test the sounds from 52-6C are the ones that seem garbled. All the other sounds seem...
I checked the continuity D18 to B16 and the two pins you mentioned tested good. Of the two traces that go under D16 I found the one to the left that went to/near E13 and that one checked out good, but the right trace I haven't found exactly where it goes yet. Looking at the schematic now.
I broke out the high zoom lens and did find something on the D18 chip. Looks like some corrosion or leaking from the chip and some cracking or bubbling (not sure what it's called) on the board between two of the legs...
Sorry for the movement, but lost the cable for my camera and had to record from my phone.

Yeah it is the same sounds that have the issues and have the same distortion every time.
I have a TMNT board that is having issues with the mainly playing the voice sounds.
In the start when one says "Fire!" and then splinter saying "hang on april" it's all distorted. All the other sounds work and sound fine.
Going through the sound test everything works well up to about 4A (50's...
Have a K7000 that has a few issues not sure if related or good place to start on it.
One issue is that it will be fine for about 5mins then every now and then it will seem to short-out. the screen will start to scramble for about 2 seconds and then it will go back to normal and will keep doing...
