Re: PSU17IPS12 Component Identification and help
I am ordering the TL431 from ie.farnell.com. i see quite a lot of versions to choose from. Could anyone guide me as to the correct one please?

However I have measured several different standby voltages from about 1.5v up to 3.6v at different times with no apparent consistency between them.
After putting the board under a microscope I have...
