Wanted - MTH Protosound 1 Bottom board

all u  need is a 180 ohm 1/4 watt resister if the rest of the board is ok i can replace your resister and mail it back to you! what did you d to burn out the resister?

I'm not sure what happened to the resistor.  This was a NOS engine from the warehouse.  I replaced the white battery with a Radio Shack 8.4v battery before running it.  It seemed to work normally for a time, but the battery didn't seem to be charging. Then the shut down sounds and  the continuous sound between switching from neutral stopped.  I replaced the battery with a BRC and it didn't  help.  I then noticed this resistor was blown out.  About how much would you fixing this board cost inc shipping, etc?

well what usually happens if you fired it up with a white dead battery which by the way is over 20 years old is shorted and burn's up the resister which I told you about, that's why I offered to repair the board for you cheaper then buying another board!

I'd be interested in sending the board to you for repair.  I'm in Virginia and the board will fit into a small box so shipping shouldn't be too much.  Let me know what you're thinking of as far as repair cost.

just sent you an email ! I emailed you and answered all your questions call me!

Alan, are you not getting my emails?  You should have received the board yesterday and I've sent a few emails asking you to confirm this.  I've not heard anything from you for three days now.

Alan, that is not a 180 ohm resistor. Where did you get that info?  Has nothing to do with white battery, unless it shorted. G

Alan, it's been several weeks since I sent you this board and now over a week since I've heard back from you.  I've sent you several text messages with no reply.  What's the status of this board repair and when can I expect that you'll be sending it back?  This seems to be taking a long time for a simple solder job and it's unnerving that you don't reply to messages.

What he really needs is a 24 ohm resistor, that's what the color code RED/YELLOW/BLACK means.  The GOLD is the 5% tolerance rating.  Also, it's a 1/2 watt resistor, not a 1/4 watt.

I have plenty of PS-1 parts if you need them.  My e-mail in profile.  This whole white battery thing is a real ****er to me.  I just worked on a PS-1 that had a burst plastic shell on the white battery.  The engine started up and was working fine other than a motor drive section issue having nothing to do with a battery.  G

I just sent back two repairs that I removed the white battery.  The myth that they don't leak is just that, a myth.  True, the battery looked OK, but inside the battery clip on one the contact had rusted so much that it separated inside.  The other one was similar, it just hadn't managed to do so much damage.

Well, like I said, this was a NOS engine and I removed the white battery before I ever put it on the track.  I replaced it with a new Radio Shack 8.4v rechargeable and it worked fine for several days.  Then it started not playing any shut down sounds and then I noticed the resistor next to the battery socket on the board was blown.  Hopefully once the resistor is replaced and I use a different 8.4v battery, the problem will be solved.
