Onkyo TX-SR875 Remote corrosion.

[Number 47]

Hi guys,

Bit of a catastrophe, batteries leaked in my remote and now the IR is not working. Found the damage, I'm handy enough at soldering but I have no idea what to do with this. Can anyone advise if this is repairable? If so, how to go about it?

Much appreciated.

clean in with vinegar,
that will remove the corrosive.
then use a meter to check the tracks.
personally i would rub it down to clean copper & tin it.

I have cleaned it with vinegar, had a rub at it with an eraser. Lost my multimeter recently in a messy divorce so I will have to buy another tomorrow.

The copper is badly damaged as are the tracks by the looks of it. When you say rub it down and tin it I'm assuming you mean sand off the copper and replace with solder?

Sorry, I've replaced caps and done automotive soldering etc but this is new to me. Is there a way to repair the tracks too if damaged? Can i run a wire or something?

Many thanks for your help.

not sand, it will go through the copper.
i use the back of a blade, or a flat screwdriver.
just to remove the green layer and any corrosion.
then as you say, use the iron to coat it in solder.

Yes you can run wires in place of the tracks if you know where they run to.

Thanks guys, can't do this at the moment due to being skint and not being able to afford a new multimeter but I will return with results when I have it done.

Skint = broke I take it ?

Exactly that. Family court eating my money.
