Remote For Prepaid Meter Damaged
This remote for prepaid meter was brought to me by a neighbour already opened with complaint it does not show digital numbers when press button are pressed, so as a result she can’t load her token to her meter. So when device was opened she noticed battery had leaked with the battery acid damaging board.
So I did primary checks on board, there seems no component burnt, however battery acid had done damage on board by burning off some tracks connecting to some numbers.
I could hardly see these broken tracks with my naked eyes, but with the use of magnifying lens. So I used copper tracks peeled off from a condemned phone charger board to do the resoldering work, in other to fortify it, I also use 4 mins glue on it and use razor blade to trim it so that the press button can have contact with pads.
Then assembled everything together with a set of new alkaline batteries (Duracell).
