If it is a horizontal line is straite or zig zag, if it is straite then problem in your vertical section,please check the supply of vertical section or output ic of vertical, if it is zig zag line then it could be dry solder in the yoke connector or vertical yoke open, please let me know the vertical ic no.

Pls note that my experience is with the phillips 27" model27PT6341/07. It may not be the same board as yr model, as I can't remember nor find the service manual anymore. (browse around online for it though)
However, after taking the back off. Look close to the rca jack and svideo connection. Mine is located about an inch from the svideo connection.
Here are some pics that may help you.
The new one is the black and gold one marked 10uf 100v in the pic.
Other users have advised to go as high as 10uf 250v, to avoid having the cap overload again.
PS. I had the lines for about 2 weeks. They got steadily worse then one day my tv looked like it was broadcasting an hourglass. The lines converged in the center and flared outward (no pic).

If the set works fine intermittently it may be a loose connection or a bad solder joint. More likely the later. Heat will sometimes make a cold or broken solder joint work. If this changes when you lightly tap on the side of the TV you have a bad connection of sorts inside. These repairs can be expensive unless you find a good repair person.
The syncronizing signals in TV's (keeping the picture locked in) are around the high voltage transformer which is usually the heaviest component attached to the circuit boards. It's stressful over time and I've seen the solder connections crack and become intermittent.

I have seen this on mine. Check the cable going into your TV and make sure it is good. The ground portion of the cable could not be making a good connection.
