The display capacitors are frequently replaced with ceramic capacitors. These may work, but have been shown to result in drifting contrast on certain LCD displays. This is caused by ceramic capacitors' characteristic where the capacitance varies based on voltage load. As such, I would recommend replacing them with tantalum caps instead.
The 5300c shipped with LCDs from two vendors - Sharp and Toshiba. The Sharp panel has electrolytic caps on it, the Toshiba panel does not.
