(Attempting to) repair washing machine control board.

[tiago]

I have a washing machine with a semi functional front panel, its a pain in the ass because you currently cant change from the defaults.
I pulled the board(of course its potted  ). One pin of the transformer is burned followed by TVS1, D8, IC6(TNY267P), D18 and MIG10J503HA.

I'm having trouble determining what the transformer is, the top markings are 20A DH 741B. I assume i will need to pull it and measure it out.

What does TVS stand for? It visually looks like a diode to me. I tried to upload a picture but failed.

I'm also having trouble sourcing a replacement MIG10J503HA which is made by Mitsubishi, i cant find a datasheet. A google and ebay search brings a Toshiba MIG10J503H part. Wondering if anyone can find datasheets so i can determine if this is a suitable replacement as the toshiba part seems to be the same physical package.

Datasheet for MIG10J503H: http://www.bdtic.com/DataSheet/MITSUBISHI/MIG10J503H.pdf

Octopart lists both H and HA, but gives no clue as to what the difference is http://octopart.com/partsearch#search/requestData&q=MIG10J503H

Sorry to hear.  Just for info, what type of washing machine is it?

Its a nfw7200tw, the board part number is 34001499.

I found one for 100 bucks on amazon so i ordered it. Im going to order the two IC's that seem burned and give it a whirl if it works i can say i fixed it. If it doesn't well i found a cheap replacement hahaha.

Im going to order the toshiba part that seems readily available.

Sorry to read.   Good luck.

It may not be worth servicing given so many flaws.
