What do you people would do?

-Reset with Clip will erase everything I have installed? Will be that enough?
-Re-flashing Firmware?

I also tried to replicate what you're seeing, but my result was the same as Han's.

As always, performing a backup (see the ARCHIVE command) is advisable if you are concerned about losing data. I would recommend doing this before anything else.

The message you're seeing makes me wonder if there's something unexpected in one of the system-created objects that the calculator uses in the plotting process. If you don't mind losing previously-created plotting parameters, you could always try deleting the following objects: TPAR, PPAR, ZPAR, X, Y1 (Y2, Y3, etc.), EQ. Then try the same steps you outlined above to see if the problem is cleared up. Again: make a backup first if you're concerned about losing anything.

If that doesn't clear up the problem, I would try a "soft reset" -- press and hold the ON key, press and release the C key, then release the ON key. This will clear any stack variables, but all saved objects should be OK as long as there's no file system corruption (which is very unlikely).

The "paper clip reset" would be a next attempt, though I would be surprised if the results were any different than the soft reset.

I would never say never , but the likelihood of needing a firmware update is very small. Clearing out the entire system with "ON-A-F" would be both easier and faster, though it would (of course) cause you to lose all HOME and port 0 contents. Ports 1 and 2 should be left intact, though. Again: see the ARCHIVE command. It's your friend.

Hi DavidM,
Nothing helped. I manually purge all LIB and other stuff except the HP Orig. LIB.
Then, I repeat the procedure above and now I can not enter the "Table" menu any longer, it just beeps and nothing else. Before there was displaying a Table with Function values.
After re-flashing the HP50g, I can not enter the Table display from the Graphic Display also.
So there must be some problem with the other LIB that I have had installed.
I will install them one by one again and post here the result.
