It sounds like you have a FLASH FAIL error message on a Sony Cybershot.
This solution was provided by acem77 at agorarequestdotcom:
1st I ordered the service manual from http://servicemanuals.net/index.html
2nd I downloaded a RM95 emulator program. this program actslike/replaces the remote commander sony techs use to change settings.
http://stanza.techfocus.net/camera/rm95.zip in side the zip is the RM95EMUL.EXE and RM95DUMP.EXE
3rd I made the LanC Interface Cable on this web site http://www.hardwareanalysis.com/action/printarticle/1464
the steps above save you $200 in service tools. The cable parts cost about $12 the manual cost about $30.
I can sell you a cd copy cheaper if you have the same camera.
when you are ready plug the cable you made into the (ext flash) or (lanC) port on the sony camera.
Put your camera in play mode and turn it on. Then start the RM95DUMP.EXE program in a dos prompt.
Type (RM95DUMP.EXE>factory.txt) this will save a copy of all the setting of the camera to your pc.
Now you did that run RM95EMUL.EXE.
You will need the service manual to know what settings to change.
I had to change these addresses to unlock page d with the flash error setting.
Set address to (reset all values to default after page d is changed and saved)
Page: 0 .address: 01,and set data: 01.
Page: 2 .address: 03,and set data: 00.
Page: 2 .address: 00,and set data: 2d.
Page: 2 .address: 01,and set data: 2d.
Page: 2 .address: 02,and set data: 01.
Cant change this setting until you change the above settings
Page: d .address: 67,and set data: 00 (if you have an error this will be 4 set it back to 0)
Write/save the new change to memory
