Viewsonic VX910 Capacitor Replacement

My main monitor, a Viewsonic VX910 built in 2003, has succumbed to the capacitor plague.   Below is a list of the aluminum electrolytic and polypropylene film capacitors on the inverter board.  On my board in particular, only the 330uF 25V electrolytic capacitor and one of the 0.15uF 250V polypropylene capacitors appear to have failed.  Nonetheless, I am going to replace all them, as all of the electrolytic caps are of the infamous CapXon brand.  There are also three ceramic disk capacitors, eight multilayer ceramic capacitors, and one box-type polypropylene capacitor on the board.  None of those are subject to the capacitor plague, and their lifetime is quite long according to the spec sheets I looked at.  In addition to the inverter board, the monitor has a display board with fourteen capacitors.  I see nothing on the net about replacing those caps, so I will leave them be.
