Sounds like your capacitors have blown on the pcb. This happened to me my tv would click for ages before finally coming on. I bought 4 capacitors from maplins for 54p each and soldered them on to the board. I have no experience of doing this so was a bit worried but took half an hour at the most and tv worked perfectly afterwards. I bought 16v capacitors with 1000uf, try this link http://www.maplin.co.uk/Module.aspx?ModuleNo=13472
