Dear R Flowers,
Your reply is so helpful since you experience similar symptoms as what
I have described. Last night, I removed the TCM and stared at the
board for quite some time. I could not see anything noticeably
damaged. I went ahead and ordered a rebuild TCM, and I plan to
install it tonight. Would you happen to have an idea why these
symptoms occur during wet weather? The area around the TCM and the
TCM itself were dry. Thanks again for everyone's help!
