PS3 board component - replacable???

Not sure what happened, but I'd say it's not that likely that the inductor you indicate is the root cause, more likely it's a casualty of the malfunction.

Need to look under the board too.  Was a coupler wire pinched or grounded?  G

1) I was using the Z1000 running at 16.7V.  You might be right that it was not the root cause.

2) No John, it's the bigger piece right next to what you pointed at.

3) I didn't look underneath.  I don't know how a wire could have gotten pinched or grounded since I have never before taken the top off of the tender - there is no reason to except when this happens.

Back to my question: assuming the piece that is discolored is bad, can just that component be replaced or does the entire board need to be replaced?

thanks - walt

Walt,

PS3 boards have much smaller components than do the earlier PS2 boards and are, therefore , considerably more difficult to repair.

However, if anyone can do it, that person would be George (GGG) here on the forum.

It's hard to see what you're point out as far as discoloration. 

However, the same comment applies Walt, that inductor is very unlikely to be the root cause, something else died to cause the overheating.

Wires get pinched for a variety of reasons, and it's not all that uncommon to see them pinched from the factory.

Walt you have nothing to loose but postage.  I have repaired some boards.  Sometimes components fall off (diodes on HO boards, Caps on O).  Maybe the coupler got internally shorted,  If so that may cause some serious damage. 

What was that something you were trying?   G

George will take care of you. I had two Proto 2 boards repaired. Fast too.

Thanks guys.  GGG I might contact you - I'm currently talking with a repair person that has been doing my all-too-many MTH repairs and upgrades - Bob Barth.

He said he can't repair the board but it might not be what's bad.  It's hard to say what action I should take: hand it off to him at York and wait to see what he says versus just sending it to you without his comments.

His repairs and upgrades have been very well done and if you know my bad-luck history with MTH stuff, he's done quite a few for me. 

That 'wanted to try something' was a track design that I was thinking of using on this year's Christmas layout - wanted to see it in action - HA, that flopped!

Thanks John - you're most likely correct.  The discolored pieced is right "below" where you pointed - you can see it around the perimeter of the piece on top.
