When powering up the tv there is no relay click but the LED indicator on the front lights up. I also get no picture or sound. The pc boards are covered in dust. I think it may be a bad relay or fuse but I checked all the fuses and they are fine.

You have no high voltage, like many in this forum, this model of Philips has some of the same problems. Look around here you may find the answer to your set. If not check Vertical IC, TDA8177, audio ic on signal board up front on left. check Power supply first for blown fuse, 1000, 2004, 1300, 1900 etc. No sound or pic means something is open. Does set has L E D lights on front of set?
