    SA-HD52 1 Default Crosstalk/static after replacing selector switch IC?

    Hey,

    A month back I replaced the selector switch IC on my Panasonic SA-HD52 as the radio was still playing when I selected the CD, it did this with the tape and record too.

    Now when I replaced the IC it worked perfectly, no cross talking and I left it at that for a month and have come to it today to play a CD (you can hear it spinning) and the issue has come back although with another issue.

    Both issues are random, the original problem where the radio will play over other playbacks has come back and another time you turn it on it will refuse to play anything, all you can hear out the speakers is static regardless of which switch you choose.

    Something else I noticed is that if you turn it off for about 15 minutes and come back to it the radio will work but if you switched to tape and then back to radio it no longer works?

    Is there another chip I need to replace other than the selector switch IC? I solder at work so I don’t think my soldering has caused other issues. I have the service manual but I can’t see what else the issue would be?

    MacBook Pro A2251 - 820-01949 Voltage Drop and unkown issues.

    Hello forum,

    I'm still relatively new to the world of electrical repairs.

    I have a Macbook here that I can't figure out

    When the battery is gone, the USB input consumption goes up to 20 V and 0.06A. But it breaks down after about 2-3 seconds and you can also hear a small ticking on the logic board. But I can't pinpoint it exactly.

    I removed the logic board and took a few measurements.

    But I can't really figure it out.

    At first I thought the infamous CD chip was defective - but then of course you read more on the internet...

    Advice sought - Selector switch knob repair
    by ClockChip
    Hello Everyone,

    I am seeking to repair a knob on an old (circa 1971) Panasonic clock radio (a model RC-6900). The good news is that I have the small, easily lost knob. The bad news is that the knob has come off a slotted post and I need to re-attach it in such a way that I won't have to worry about it coming loose again.

    Here is a picture of the bare slotted post (if I have the term right) the knob should be attached to:



    As you can see, this is an Old School selector switch, which means it's pretty stiff. Put another way: the knob has to fit...

    Micro Momentary Push Switch?
    by Natob82
    Great to be here! I'm a newbie here trying to find a "micro", momentary push switch to repair a Sony "clamshell" video walkman. This micro switch has long since discontinued by Sony, however I hope there are third-party switches of the same size and functionality that I might be able to source to play the same role. The purpose of this switch is to tell the video walkman that the user has activated the mechanical tape eject button, turning that physical action into an electronic signal that tells the tape transport mechanism to open so one can load or eject a video tape. I...

    NEC TurboExpress On/Off Power Switch Replacement Help
    by grimacelord
    Hello,

    I've been working on a NEC TurboExpress and I accidentally got the plastic inside the power ON/OFF switch too hot while doing other repairs and melted it. At first, it would still power on when sliding the switch, but you had to really press inward while sliding to get it to work.

    I removed the switch component and tried to gently melt the plastic back so it would work more reliably and all I managed to do was make it worse.

    I need to find a replacement On/OFF switch for this, but having some trouble figuring out which kind of switch I need....
