In VCR mode, I'm not seeing any video when I press play on the GL2. The LCD remains blue and says "TV SCREEN." It's been a while since I used the cam, so maybe I'm a little rusty...It was working fine a month ago. I've tried playing a few different tapes that I know have footage on them. Any suggestions?

Could it be you switched it to some mode where it only plays over
the output connections and not the LCD? You may want to remove
all batteries (including the backup one!) and leave it a while to
reset it back to factory defaults. Otherwise something may be broken?
