the 24c02 is a memory chip inside. Unless your a tech - you can't repair.

Mine did this also, I got a replacement and it also read F--H. I took all the screws out - they hid them under the bar code sticker and under the stick-on faceplate where the buttons are - then found that the screws on the load cell which is sort of like an aluminum tuning fork had been tightened so much that the cell was reacting to the screw force, not the scale pad. Release all the pressure and you may be able to make it come alive again. One of my two is working now but calibrating is another thing all together because the linear counting depends on the loadcell screws being set just right.

that dosent work in the case of an f--h display at least in my case i think the f--h stands for f**king hopeless

This unit scale may need to be reset. see if there is a reset button, if not, try removing the batteries for a minute or so, then replace them with new ones.
