I think i may have blown the amp on the surround sound as I have problems recieving sound from the centre speaker. I have tried a replacement speaker but problem persists. Can anyone give a repair solution that would be financially viable? R there any repairable parts that can be purchased and fitted or would I need to give it to an expert to fix?

If your surround sound receiver unit has rca audio inputs(red/white), you can hook up any brand of DVD player that has rca outputs. You would hook the yellow output from DVD player to yellow input on TV. Hook red/white output from DVD player to red/white input on surround receiver. Hope this helps.
The problem is caused by the PULSUS PS9829B digital audio processor. We ordered it in from a Samsung authorized service centre. Problem is now solved. Unit works perfectly. If you have never tried working with surface-mount ICs I would skip it if I were you. This IC has over 100 pins on it. However the part is available from Samsung. Print this comment and take it to your locat service centre along with your receiver. They should be able to repair the board unless they are wussies and cannot do surface-mount work.
It sounds like the speakers themselves are the problem rather than the amp.
Although, it would be rare to have overdriven/blown the surrounds.
My suggestion would be to isolate which speakers or channels (on Amp) are at fault.
Swap left and right to see if the problem transfers across.
adding more speakers in parallel reduces the impedance, causing the amp to work harder. if you reduce the impedance to much and turn the volume up its a bit like making a short across the output, and has probably damaged the output stage. if you are really lucky it may be fused and simple replacement will fix the issue. if not it could be a costly repair. always observe the minimum impedance rating on your amp and match the speakers to it, never less than it
