Got a problem with a LOTR LE. LOTR LE is 2009 and differs from standard 2003 version as it has Whitestar CPU/Soundboard II connected to a SAM driver board. I am pretty sure my problem is the Whitestart CPU Soundboard II so posting here for help as someone may have seen this on any machine that uses that board.
The Problem
Games plays fine , but after a few games the Music stops. Playfield and playsounds are all working but no theme music. Then it may come back and then stop again
After a few more plays then the sounds themselves start playing up, I,e, distorted sound, missed calls , screech sounds , different volume. Sometimes music will come back and then will go again.
Also when any mutiball starts the sound is noticably louder ( for call outs ) until multi ball finished
I have done the obvious no loose wires , all ribbon cables correct
I have had a search about , one advice is to make sure Eprom is flashed to Stern OS8. That means 8 flashes at bootup which mine has so Have assumed that’s ok, but maybe its got corrupt ?
Another is corrupted Sound Rom chips but does not make sense to me if works initially ?
If I turn machine off , take out all the Sound ROms ( U7, U37, U36, U21,U17 ) and then reset them. Then it all works – for a few games and then same pattern.
Equally if I turn off and take the batteries out the put all back , Then same again , Games is fine for 2 or 3 games and then the music stop
So a bit stuck.
Is it the Roms? Seating of Roms?, board needs reflashing or something else?
A replacement board is about £450 , which I am pretty sure will fix it , but thought I would ask the forum to see what can be tried before I take that option
Any ideas ?
