hi you can get a service manual which includes schematic from this site:    http://www.download.nitd.co.uk/news.php      you will have to register with them before you can download it, but this is free.   Plus you will probably you will have to download  another free program to (shareware) to decompress and read the rar. files  I used  the one for xpwindows:  http://downloads.zdnet.com/download.aspx... I got mine for a phillips set no probs!!
