Does this happen when testing the switch with a ball, testing with your finger, or testing with something else?

If you disconnect the playfield and test the switch matrix using jumpers do you still get the error?

It looks like only your optical switches on the matrix are malfunctioning but I don't know what might cause that. Low voltage maybe?
cfh might be able to suggest something.

Power off and try reseating the connectors on the driver board.

I know i posted in this thread but i did not realize it was 7 months old!!!???
To the OP are you stating it worked before and now its having other issues??I'm lost

I would post your question in regards to if that's normal in the LOTR club thread. Possible it's a board problem, but would be unlike any I have ever seen on the switch matrix.

It's very possible that the previous owner or someone wired a switch/switches in the wrong order.The switch/switches that are registering multiple switches would be a good idea to look into and see if the wires are in correct order and test diodes(If any are there) with multimeter.

Yeah I'm the guy who pm'd when I found your thread researching similar problems... I have every switch you indicated on mine also registering double in switch test, BUT my "mini PF U.L." (potd, top left switch) does as well and also registers/triggers the next switch on the row, the orthanc opto switch (top vuk). You don't have any oddities with that mini pf switch?

I asked about this in the club thread (on page 53 I think), and one guy seemed to indicate the same behaviour with his lotr there, including the "mini PF U.L." switch behaviour, however his did not exhibit the problem when disconnecting the switch connectors at the board and testing with jumpers as you say yours does. That kind of points in two completely different directions... To double check, you removed the switch/row column connectors on the board, and jumpered one pin at a time down the line on the board down those headers per this process? http://www.pinwiki.com/wiki/index.php?title=Sega/Stern_White_Star_Repair#General_Switch_Matrix_Testing

I guess I need to try that here on mine next, but I wondered if the problem may not just be with the Stern switch test itself - I have no problems in game play and from what I can tell none of the switches act up at all during actual play. I could not tell any switches were double registering when a game is started, and switches are manually triggered... I may just drop it until an actual problem is seen in gameplay though.

Looking over the readme file for the software there have been many bug fixes throughout the different versions. Are you on version 10.00?

Honestly i ran the old version roms for a long while in my lotr and never had any problems like what is being stated

That would have been me....
What I was trying to say was that the "mini pl ul switch triggering the orthanic opto" problem didn't occur when testing the board with jumpers. The other problem does.
The switches that are activated twice in switchtest are the trough, lock, vuk and saucer switches, the shooterlane switch and the stacking opto. Those are all switches that the ball activates for more than just a short moment. That almost can't be a coincidence and the game plays absolutely fine, so I think this behaviour is normal.

The mini pl ul switch behaviour occurs with just 1 row (CN7-P9) and 2 colums (CN5-P6, CN5-P7) connected to the board. I haven't looked into this any further. I noticed that in gameplay the game doesn't fire the orthanic vuk when the mini pl ul switched is activated.....
