My first post and I'm hoping someone can help...
I've had a DW6600, with an 1199 module since it was given to me new in 1994. No issues. Ever. Recently, the digits were disappearing whenever EL button was pressed, so I figured it was time for a new battery. I took it to a reputable place in the area. The guy tried, but mistakingly put the battery in upside down, so the polarity was wrong. Digits read all 8's. The new battery was put in properly, and the watch keeps the corrrect time, but now the watch is really acting up. Without pressing any buttons the watch will start making a high-frequency sound (think of a hearing test) that goes on for a long time. The beeps from button presses, top-of-hour and alarm now sound "crackly" at times, and less frequently - the entire display will disappear. The sound will stop on its' own after some time, and when the display disappears, a few button presses will bring it back.
I searched the forums, and haven't found anything with similar symptoms. Has anyone experienced this, and could possibly tell me how to fix it? The watch has a lot of sentimental value, and I'm hoping it can be fixed.
