I've googled, youtubed, and searched the forum, and while there is lots of info on protosound 1 problems, I've yet to find a "how to" on removing the boards. Maybe it's as simple as just disconnecting everything, but I'm not an electrical expert, so I'm needing some guidance.

the ps1 boards have a heat sink which is underneath the boards where the 8.4 volt battery if I remember correctly . you have tot urn the engine upside down when you remove the screw the board will come loose you will have to disconnect all the white red and yellow and maybe green wire plugs then you should be able to take the board out. there can be differences but you have to give us Engine item number if you want exact help! just curious but why do you want to take the boards out?

Thanks Guys - The idea here is to remove the boards and replace with a dallee e unit and just get them running again. 

The locomotive I currently have on the workbench is a Premier SD-9. MT-2110LP.

The reason to remove: It won't run. It powers up, it makes sounds (although there appears to be a speaker wire loose) I changed the battery to a fresh 8.4v rechargeable (which I also just put in 2 PS-1 steam locomotives which are working fine). I performed a reset 18 using my Z750 transformer (which I have done before with this transformer when I purchased this locomotive second hand). No change. I performed a chip reset with the reset kit - still nothing. I don't have access to a Z-4000 transformer. 

I am fully aware of BCR's and realize had I put one in I might not be in this boat...because apparently BCR's are the cure all to trains that don't run. (Sorry to sound salty on this - I'm just tired of hearing this as the cure all for seemingly every problem in the history of model railroading.)

So...my options are take it to a tech who wants about $40 to just look at it, and then who knows how much to fix it or I can just take the boards out and for $70 or so put an e-unit and some directional lighting in it and get it running (along with two other locos which have different PS-1 presenting problems). I have a very limited train budget, so PS-3 upgrades and such aren't really in the cards. I'd rather have them running and circle back around to sound in the future when hopefully I'll have a little more budget for such things.  

Thanks again for any help/advice.
