I've always used 35 volt caps where the originals were 25. With the newer Panasonics, the sizes are the same as the 25 volt versions. At the last Samsung seminar I attended, the reps were recommending the same, as they had run across some 24 volt supplies with 25 volt caps in them -no margin whatsoever. I just finished three Insignias that all had bad caps, and went up in voltage (with a corresponding drop in ESR) on all but the four 16v caps for the 5v/3.3v standby circuit.
My favorite caps are the FC and FM series from Panasonic - where going up in voltage always yields a higher ripple current and lower ESR. 680@25 - .052 ohms ESR, and 1220mA Ripple current. For the same in 35v, the ESR drops to .035 ohms, and ripple current increases to 1815ma.
