Once you know the power input is good, then most likely the DC-DC board is toast. youll need to fix/replace it. 
Unfortunately on the 190/5300, the DC-DC board is part of the motherboard and can not be removed to be replaced like on a Wallstreet G3 or other Powerbook. If needed it needs to be fixed - some how. Outside of checking traces and replacing parts, the area is very tight to work in.
