My camera does not play back recorded video or record anymore it just blinks a yellow triangal & the letters FN on bottom right corner. My camera is a Sony Digital Handycam DCR-PC101 NTSC

SOURCE: C:31:23 error with DCR-PC101 Sony camcoder

Had the same error message on my TRV-720, and could not come up with a solution for weeks until I found this website:

Now the fix you will not believe, nor did I at first, but requires you to power off the unit completely and "Smack it" a few times fairly hard.
Now you may do this at your risk, but I swear it fixed mine and all the other people listed at the above web site.
I thought it was a joke - but it works!!

Good Luck!

If it has memory stick, Make sure your memory stick is in. Your memory stick is full. Delete the unwanted pictures from the memory stick or use a differnt biger memory stick.

I looked in the manual. It seems your camcorder does not have a slot for memory stick. But you may still save pictures on the tape. Here is the link to download the manual

Please read Page 40 "recording picture on the tape".

GOOD LUCK !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
