The mobo completely shorted, in snes mod.

Hi I'm doing a mod. 50/60 release to a snes and the region, but a wrong cable assembly, gave me melted broken and would not light up, the fuse I replaced it, but I find all the ground and positive points in short, I do not know that component ruined can give this effect. I replaced the fuse, unsoldered the 7805, but I always positive and negative shorted even from the holes of 7805.
What should I test?
Thank you

 

Can you make a high resolution picture of your SNES and point out where on the board you did modifications?

 

The mobo is a chip01, in short are not unsoldered pins, those I tested them with tester, only the merged went. I do not see any drops of tin on integrated, it altro..tutto was turn on the console and the 7805 controller has warmed up a lot; Then at the second firing it is not turned back on.
The installation and the one on the attached link, only that I had connected the 5V with the second switch. I can not post pictures as I have no means to do so.

2nd photo is the real pattern that I used.

 

It's impossible to help without a photo.

You've shorted something so check over your modifications under a microscope (or reverse them).

 

You can not run a so extensive, I do not see with the naked eye no tin stain. It could be interrupted at any piste area "pin 4 lifted" but I see nothing, there are no visible micro shorts or micro cracks; I believe in burnt components, I'm sorry but at the moment I have no means to post photos.

I would not be a reverse pin for 5V I made from output to input of the controller, but that works well.

 

I merged your posts - please use the multi-quote feature rather than double posting. You can hit reply by as many posts as you like and it will add to the preview text.

I said use a microscope! Or at least a magnifying glass.

Take it to a friend with a camera or scanner and get a photo. We cannot diagnose your issue without seeing the board. As it happened after you modified it, this isn't a standard fault - it was caused by your error.

 

no, not nulla..ho resolder controller and is turned on, only that, it gave me black screen. Now I reassembled everything as origin, and also the crystal, but it continues to give me black screen.
I had thought wrong. For the black screen or is the crystal to call the original (I used the one mounted on the switches) or is fried something.

 

hi path , have a look for burn marks around chips resistors capacitors etc.........

 

Ok thanks, I'll look at all the components, and I noticed that the chip under power heat shield, which is seen on the upper right side becomes very hot, just ... I'll see what I can do for me it is ruined beyond repair.

 

hmmm , i had a problem with my Neo Geo AES and i was advised to check the chips if they are really hot which is probably the culprit. I did fix the problem it was a basic fix and unrelated to the chips but yeah take my info as in if a chip is really hot it is not functioning right and could be the culprit.


best of luck
