Sony Cybershot dsc-s40 showing message "turn off and turn again" when i switch to photo or video mode

ive tried everything from doing what the message tells me to, reseting/initializing, trying to turn it on without the sd card inserted to contacting support. the method thats helped the most was taking the batteries out and pressing down the power button for 30 seconds then putting them back in which still shows that message but shows a blurry preview behind the text, usually its black behind the text for context. ive tried to install the firmware for it off the sony website but there are none since playmemories home got discontinued(idk what that has to do with it but thats what it says) ive blown some compressed air in the lens area to try to get possible residue out of the lens and that didnt work either, ive opened it up and everything looked fine. i think it may be the lens thats the problem, should i attempt to fix it myself or take it to a repair shop? any other ideas?
