I am currently working on a few tvs . I have always just ordered a new mainboard and replaced but I have a rework station I used to use for fixing cellphone charging ports so I am considering fixing the main board. my question is can I order one single eprom since they are programmed and use it to fix any tv just to keep a stock of them instead of waiting for the part to come in or the eproms all different.
