I think that is the wrong fuse but still it would pop if you have a line problem on the circuit that fuse is piping for a reason not the value but there are more issues on the circuit then what you repaired I would start digging and see if there are more popped caps! not in the power supply but else where like the hd push board or the decoder in better terms.
Thanks hope this helps if you cannot get it done take it in for a estimate as estimate will tell you the issue fixed or not and you can take that advice from that tech and repair your TV!!

Problem is in either power supply or the Y-Sustain board.
The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.
Often there are fuses on that board - one or more. Check those.
if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.
I hope this will help in solving the problem.....

Your tv horizontal section is faulty change the horizontal transistor.or the diode that is at the leg of the collector of the HOT.do other checks around the transistor cause it can be more than one component is faulty in that section.also make checks in the power there is a diode that feeds from the pout put of tv regulator that might be leaking or is open.

It will be best to replace power board as card basis. Do not make any further adjustments. Normally, it is not possible to repair a power supply board to Philips. There are some typical components, used by Philips, that we can't get from open market.
