After years of faithful service, my MTH PS2 H10 looks like its dead now. Tried everything. Now won't even be addressed anymore. Even tried on my test track alone. No power, sound, lights, etc. So, advise, cheaper to just change over and install TMC boards or send it off for even possible upgrade? I like my DSC system and what I get out of it, as I do this engine which is even weathered. So looking for advise, and who to send to. (I've never had to send an engine in for repairs, only once sent an engine out to be upgraded). The only thing I did was replace some rear parker lights, add a BCR and installed a new speaker. Has run faithfully for years. Thanks for any help.
