Hi all, I have a bush DAB radio, when it is switched on everything lights up as it should, it does its scan, finds all the channels and displays whatever channel you ask for and the display says playing radio one or whatever channel you select, the problem is no sound comes from the speakers. I have removed the board and had a good look, but nothing obvious has blown on it, so that said is there a component on it that makes the sound output? Cte-430 Driver Windows 10 there. I have included 2 pictures of the board if anyone has any ideas on it, thanks. Fsx-sialkot Project Msk. Descargar Controlador Para La Impresora Epson L200. OK, the amplifiers are type NS4148, made by 'Nsiway'. I found a data sheet; it's in Chinese, but the important information is there. Start by checking the DC voltages.
