I WAS GIVEN A MICROBITX 40 RADIO WITH A BLOWN TDA2228M CHIP. I REPLACED THE CHIP AND NOW I HAVE AUDIO BUT ITS VERY LOW AND THERES A HIS ON THE HEADPHONES, MY QUESTION IS DOES ANYONE KNOW WHERE I SHOULD LOOK TO TRY AND FIX THIS ISSUE. I CAN HEAR STATIONS BUT THERE IS NO MID OR LOW RANGE JUST HI'S. IVE TRIED TO FIND A SCHEMATIC FOR THIS RADIO ON LINE BUT THE ONLY ONE I CAN FIND IS PRINTED WITH VERY LITE INK, NOTHING READABLE. ANY HELP WOULD APRECIATED.
