i think ur unit deposits humidity . . try to clean it up with smooth paint brush over the boards and connectors . . better yet spray some contact cleaners i think this will do . . . otherwise resolder is needed . .
Well the jack you plug in has three surfaces. So when you pulled it part way out then the left speaker part of the plug came in contact with the right speaker contact inside the jack and it worked. Speakers are good so if you have checked your volume control in Windows and checked that the balance control is centered it could be that your sound card is defective. You didn't tell me what kind of computer you have and if the sound card is built into the motherboard or if it is an add on card. I don't know if you only have the Window's sound control in Control Panel or if your card has a seperate software for configuring your card but I think the only thing that might disable the left speaker has to be the balance control in Window's sound control or the seperate software.
SOunds like the emulated line out is the problem IT may be defective. Is this a button or a knob? It may have dirty contacts and MIGHT be able to be cleaned with electronic contact cleaner.
Hello Johnsabljic :-) Being an old stereo, the most probable cause are dirty contacts in all of your controls and switches - especially A-B speaker switches. Remove all round plastic knobs from your volume, tone, balance (etc.) controls. (they should be pried off carefully with a flat blade screwdriver) squirt a little contact cleaner (or WD40 if contact cleaner not available. I use a 50 - 50 % WD40 and rubbing alcohol solution in an old Visine container - but if you do this always label the container "Contact Cleaner" as you don't want someone to use it to clean their eyes and go blind) Squirt about a half a teaspoon of contact cleaner around each rotary shaft where it enters into control surrounded by the nut. Do this also with all on/off switches and sliding controls as well. Manually turn all rotary controls back and forth so the solution will work itself in. Move all sliding controls back and forth also, and click all switches on and off as well. I would let it sit for about an hour before you power it up. I run into this alot when I refurbish old receivers and eight track players. Good luck, Fred
My trick if you wanna do a good job, you remove the knob, unsolder the potentiometer, remove the claw and ''clean'' the inside carbon or switch contact with the eraser of a pen. Re assemble everything. Dont be lazy and use can of electronic cleaner, you'll be losing your time... ITs pretty much job but thats the way to do it.
When turning the knobs you might get a crackling noise if the amp is old, The knobs get worn. Either you can replace them or repair them with a tiny squirt of WD40. Check youtube videos for help.
As for the fading sound, That would be your valves ... They need to be replaced ... I suggest taking it to a repair dhop for that because they need to be matched.
It seems like the speaker jack tip needs cleaning, or the contact has become bent away from the connector and needs to be re-aligned. The Passport is a portable system, so after years of plugging and unplugging the speaker jacks may be worn. Try using the "Stereo 2" connectors. You can also try cleaning the jack with electrical contact cleaner, and. a cotton swab.
reset camera by removing battery completely for about 10 seconds. otherwise, time for service. sounds like a processor board issue. you can use a contact cleaner sparingly, available from frys electronics or any other electronic reseller like radio shack. good luck mark
Sounds like a cold solder joint around the imput to the power amp stage on the board. If you can get to the board take a bright lamp and a magnifying glass to chek for solder joints that are frosty looking .If so heat them up and dab solder to make them shiny.
Good Luck
