Panasonic 5250 popping noise

I have a 5250 and when i put on radio or tape player i get this popping sound and cant hear the music. Its the left side only. I tried the usual methods of deoxit in the record bar and function switches but still nothing. I un soldered the speaker and tried a different one but same problem. If any one can give me multiple answers as to what it may be, that would be appreciated. I also tried to press record with a blank tape but it makes that sound even when record is pressed. So i just left the left side unsoldered and can here the left channel now. Any solutions/ideas?

Do you mean a repeating pop, or a single pop?

It could be a bad capacitor! Check the main board for any swollen capacitors.

Did you try cleaning the headphone jack?

BoomboxLover48 and baddboybill are right. Can you give us some images from the inside the unit? Bad electrolytics usually leak a little bit or get swollen.

I sprayed some deoxit on the solder joints around the volume area on the circuit board. That seemed to fix the issue, however, if i raise the volume too loud i get a humming/bass noise out of left speaker only. Any thoughts about this. Thanks
