    Having a hard time understanding what you're asking. Do you intend to remove the board from the TV or use it in the TV with the TV's speakers? If the latter, you should be able to run a cable from the phone's headphone jack to the audio jacks for the TV's composite-video input. Then you could listen to the phone by switching the TV to that input. But if you want to use the board separate from the TV, you would need a power supply for it, plus you would need to hook speakers to it.

    Yes I'm lookin to use the board with power supply separately as the tv takes up too much space ( it's a spare )
    So would this be safe to do then? Thanks for the reply mate!

    Probably, though you'd need the proper power supply and everything would have to be grounded properly. The power supply in the TV no doubt has multiple outputs, some of which may be very high-voltage if the set used CRTs. It's not something you should attempt unless you know your way around electronics. Would be a great deal easier, and possibly not to costly, just to get a cheap standalone amp or receiver for the purpose.

    Cheers and ino it would be but I'm always thinking up things to make and experiment with... so if I took the amp and power board out and removed the wiring for the monitor connecting the two then grounded whatever was grounded on the original board / casing to the new casing?.. would that work ? sorry for not explaining it very well haha...
    Also any ways I could wire an aux input for my mp3 player into am old DVD player with loads of outputs but only a line in for mic nothin else? Cheers guys for the help...
    Ive also got a good few motors from blenders and lawnmower and a Hoover which I'm itching to make into other things so any ideas I'd appreciate... starting to feel like a bit of a hoarder haha

    Not sure. Problem is, you can kill yourself finding out.

    Also any ways I could wire an aux input for my mp3 player into am old DVD player with loads of outputs but only a line in for mic nothin else?
    Mic input on a DVD player? Anyhow, you could try using that input and turning the volume on the MP3 player way down. If it still overloads, you could maybe cobble together a 10- or 20-dB pad to put between.
