[countrywill]

Hi I have just acquired a Bush ly2211wcw tv/dvd combi hd ready tv that was stuck in standby I have replaced 2 capacitors on the power supply but now have no sound, there is sound through the headphones but nothing at all on the speakers can anyone advise if I am correct in suspecting fault is on main AV board?
Thanks
