Loss of receive Galaxy 44v

[marveylus22]

Okay I have another problem with this radio. Today I disabled the talk back at j-15, and put in an on off mini toggle switch and it worked fine. Then I put a heat sink on it from a 99v, and it worked fine. Then I changed out the stock tr-51 a 2sb754y for a 2sb817 thats when I lost my receive. I pulled the 817 out, and put back in the 754 but still no receive. The radio transmits just fine, but no receive. One thing I did notice there was no audio in PA mode. Any help would be much appreciated. Thank you.

sounds like to me,you might have toasted the audio chip.

Tahts what I was thinking. I did move the audio chip back to add some more heat paste, and dummy me didn`t secure it completely before testing it. Thank you Rambling man.

Well I changed out the audio chip, and still no RX.

hey bud,so no change with the audio chip huh,well one more question,does your s-meter work,and if so like if you put it on channel 19 or your busy channel where your at there.do you show any receive on your s-meter or not.if so id also check tr-42,this is your audio pre-amp.also when you changed out your audio chip,did you check the assc. shunt capacitors in that area.such as c-145,c-146,c-150,c-151.for any signs or burn.and do you have a schematic of your radio or not???
