Bought a new power supply but not really sure if that's the issue. Haven't turned it on since around December 2015. It's a CECH-2001A.
Issue: Upon powering up, goes straight to system update screen, loads to 31% and then gives error message "8200F147". Hard shut down and holding power to reboot will not enter safe mode after two beeps. Will either go straight to update screen, or if held will beep once...and then go to update screen. Rinse and repeat.
What i've tried thus far:
1) Sony's insultingly non-helpful shut down and restart/unplug replug option.
2) multiple attempt at entering safe mode
3) removed HD, booted up, waited for HD error, reinstall HD and restart
4)Downloaded latest firmware to flash drive, however can't select it since as previously stated I go straight to the update screen and cannot enter recovery mode/safe mode
Not worth the mailing in and paying $100 for them to replace my hard drive anyway. And I must re-iterate that I CANNOT enter safe mode so please do not start response with any combination of the words "boot up safe mode/boot up recovery mode."
Looking for suggestions which aren't previously listed, thank you in advance.
