      On some tvs if you st the headphone setting to audio out, you can get sound from both headphones and speakers, not sure if that tv does tho.

          Replace the amplifier IC. You'll need to use hot air as the bottom is a large soldered ground pad.

            Is there any way of checking its def the amp ic before replacing as I wanted to avoid doing that if possible.

            I dont think its getting warm, will check with thermal gun.

                  Block condensators make problems around original IC and becouse of that you dont have sound on original IC : MrReeceyburger123

                    Update: attempted replacing the ntp-7100 and still didn't work, possibly my soldering. Oh well, worth a go! Perhaps more practise needed.

                    Anyway picked up a cheap replacement board, £14. For that price I thought it easier and quicker than further troubleshooting which may have led to a bad uc ic anyway.

                    p.s. that was a damn good price for one of those boards, all others are extortionately high!

                    All tested and working.
