Can this circuit board be fixed?
My cousin gave me this crane cams hi-6 ignition.He said he couldn't get it to work.*L* I found the problem.Can this be resoldered.
I posted this question in the tuning forum as well.

Re: Can this circuit board be fixed? (Dmc1)
I'm guessing whatever is on the other side (resistor or transistor). Is probably burnt out. If you can find out exactly what it is and replace it and check the connections then there is no reason it shouldn't work....make sure the connections still work though . Why this is in FI I don't know

On the other side thier is so much stuff it's hard to see the board it looks like the burnt side goes into a coil.though but nothing looks burnt.it kind of has a burnt smell though.So its probably fried.
Heres a little solder repair I tried.It didn't work.

That breakage in the trace isnt your only problem.
Its the component on the other side....
Coming from a former PCB specialist, that board is most definately repairable.

Re: (Tactic$)
Is their anyway to test each part on the otherside of the board? it all looks good to me no signs of heat anywhere.
Here is a pic of the other side.

Re: (Dmc1)
I put this in FI because alot of tuners know how to chip ecus thus they have skill in the soldering circuit boards field.and this forum gets more traffic then some of the others like fab and tuning.I posted in there to. I was getting impatient! hoping for some advice that would lead to an easy fix.

Re: (Dmc1)
Are you talking about the transformer....did you even replace it? I see another "black thing" That's a voltage regulator most likely, but a heat sink on a chip can be anything from a high current transistor to a complex diode. Can you circle the area on top of the board that is burnt out onthe bottom?

Re: (adseguy)
I think this transformer is the problem.It looks pretty burnt up to me.Does anyone have any Idea where I can get another one at.the part number on the side of it is 10499E.

Re: (Dmc1)
I tried googleing it, but didn't turn up with anything. What is this board. Any other pertinent numbers you can type up on google? Just try numbers that are anywhere, you may land on something ...otherwise you'll need to figure out the components it's connected to and reverse calculate what is needed so you can see what this transformer. I've never done this and never want to since it's so hard . GL

Re: (adseguy)
From the pic the transformer looks good.
Check your input resistor and diode.
If that is not it then it is most likely a FET.... It will be one on the three near the edge of the board.

Re: (tepid1)
In that pic with the transformer....
check the two resistors just to the right of the transformer. The ones that look glued to the board.

Re: (tepid1)
get an old cheap computer sound card board or what not and practice desoldering on that.
then when you feel you're good enough...desolder the connections around the burned spot and wiggle the stuff on the other side to see what you loosened up. remove/replace whatever that is and while it's out, check to see if there was something it was hiding which may have burned as well.

Re: Can this circuit board be fixed? (Dmc1)
your coussin had a short for shure.
this path took the place of a fuse, there is no componnent on the other side, this path is just mooving voltage from point a to point b.
you can resolder it with the proper material. I/E copper sheet, and good welding skiil.
your one lucky guy that this unit is not suface mounted, cuz it would have been scraped from the shortcut and unrepairable...
STD mounted plate can be modified / repaired often.
hope this help

Re: Can this circuit board be fixed? (kranked91dx)
Just for my information (since you have this apart right now) can you tell me the part numbers for all the chips on the board ?
it's definately repairable but there are 2 things u have to figure out
1- what is broken/burnt up and how to fix replace that
2- what caused it to burn up (is there a short or a problem somewhere else on the board that caused the problem in the first place)
if you fix #1 but not #2 you're going to end up with the same problem in the future.
thanks

Just to let you know there is more than jus the fet that is bad. It is something else that made the fet do that. They don't just burn up like that.

Re: Can this circuit board be fixed? (tepid1)
Also with a multimeter check D1. If it is shorted (in both polarities) that is most likely the cause of failure of the fet. Check the resistors with the meter too. The ones that are glues to the board. Just because they look ok does not mean that they are.
Just remembered from back in the day.... If your fets go out like they did your big storage caps are now probably shot too.

Re: Can this circuit board be fixed? (nuclearhappines)
okay heres some part numbers the two caps 35v 3300uf
the big white box with the ring of red wire KNB1530
the transforner is 10499e
little yellow thing looks like a fuse it looks like it connects the positive power in to the rest of the board is MDC-Z170-03 those numbers are stacked ontop of each other not in a row like I show them.
little grey box it also connects the positive cable to the rest of the board 1J63
