Question about Samsung Televison & Video
Just because the capacitors look fine don't mean they are. You will need to get a tester and check. Do you have standby 5vdc? is the main board supplying the 3.3-5vdc "on" signal to the power supply? If you don't have any repair experience, I recommend a professional diagnoses.

The capacitors for 2533,2540,2541,and 2508 should be replaced. They are all 100uf 16v surface capacitors. Those capacitors are sold on amazon.com http://www.amazon.com/Rubycon-Electrolytic-Capacitor-IMPEDANCE-Continuous/dp/B0015A8U9M/ref=sr_1_2?ie=UTF8&m=A6Q8GCHJGURD6&s=industrial&qid=1225140147&sr=1-2

SOURCE: are there any powerboards or
the power board is available from Andrews Electronics
but you should really look again at the capacitors, make sure you placed the in there correctly polarity-wise
the stripe on the capacitor goes along with the marked side on the circuit board...this is the negative leg.

Check the fuse on the y-sustain board. If you they are open replaced it with same current(ampere) ratings and try again if the symptoms still there. Check the voltages at connector (P3). Let me know the reading to asssist you further.

In normal casses, if the power supply regulator board of Plasma Ts cannot be get repaired by any means. The inverter transformer [Switched Mode Power Supply]; will get shorted windings inside it, which cannot be retifed. this is a critical part, that cannot be available at local electronic sparepart market, of as part at Samsung service center. it is best to replace it as card basis, as plasma power supplies must be very right in every respect for the proper working of the plasma TVs. Thie is quite normal case also, that unlike LCD power supply sections, plasma power supplies will get troubled soon, as it supplies more current to the plasma screen to illumitate. Just replace it. You can get it from the Authorised Service Center for Samsung at your town. It will solve your TVs problem. The oscillating frequency of the switched mode power supply of this model of TV you owns have [350kHz] a very high frequency than normal LCD or other Samsung power sections. It will have a high stability, which cannot be accuired by normal service techniques, and components in it will be of special type. OK.
