Transformer Problem

[proffesorpeter]

lets HOPE AND PRAY that the spares are out there- but hey, if its a goner at least itll be good for spares.

Hey Sparky,
I knew you would be back tonight. Not ready to give up yet...are you?
Ok, I looked at your board (actually I had to zoom it up to get a better view) First let me say that that this is a lame little board worth no more than $25.00. There is nothing on it...Which makes me think that bigger damage lies ahead on a major circuit board. The part in the center threw me a bit until I zoomed in and saw SW1. This is your off/on switch...Right? The upper left appears to be CN1 and not used. CN2 appears to have a clipped green wire, and only the black wire is used (I assume its ground). Is that the transformer wires coming in on CN4? I assume the 4 grey wires goto the circuit boards (3 zeners and 1 ground) Well, Since this is a small low cost board, I would suggest to try and locate one. Most manufacturers use a lot of the same boards in their machines to keep cost down. So see if you can locate one. The second option is to replace all the parts on the circuit board (Except the connectors) Since you charred Z2 and Z3 you will have rely on a member to read off what the part numbers are on these components. This may not be easy to do since the components numbers may be soldered towards the circuit board. If no numbers exist, then a schematic diagram would tell us what they are. From what I am told, this would be a very difficult thing to come by. I don't even know if any vendors have them, but if they do they may help. BTW, The parts on the circuit board would run about ten dollars. Its finding them that may prove hard. I also assume that the board on the right is in no way connected to the board on the left?

that pic is not an actual pic of my board its a fine working board from DrDark's machine.

THe transformer enters thru CN1

The board on the right is not connected to the damaged board correct.

I was looking at the other fuses on this machine and theyre fine if the whole machine was fried wouldnt if of affected these fuses?

I know you want someone to give you a yes...everything will be fine. No one can do that. Deal with the board as I last posted, and go from there. Its a place to start.

Im expecting the worse hoping for the best. either way its a lesson learned.

[napster]

Your young....There are many more "Lessons to be learned" to come!

R:
I looked at those parts in detail. If they were not black and thick I would have said that they were a disk capacitor as they are about the same size and shape. 1/4" in diameter and about 1/8" in width.

BOTH components are marked:
at the top ... the letter M in a box
line one ... V7560
line two .. SAN

You might be able to find this part in an electronic component substitution book.

I hope this helps
