- Hi, this video shows me and my brother Paul attempting to fix a faulty portable stereo which doesn't power up.
Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things.
I do love fault finding and trying to fix broken things so I hope that comes across in this 'Trying to FIX' series.
Many thanks, Vince.
Have to give a lot of credit to Paul. His first diagnosis was "switch" and he suggested bridging it to test :-) By the way, Hitachi was in no way a "cheap" device. It may be of old school design now but Hitachi made very good and reliable devices back in the day (judging by date code on IC, this one was made circa 2003).
I feel like Paul has no idea what Vince is on about and he agrees with everything 😂😂
You can't do videos without us hearing it right
Instead of going through all of this testing and digging through trying to get this device to work, I’m flying to China, and I’m going to find a bride that worked in the factory that made those things bring her back so she can fix mine ! Seriously though I quit painting my house today and I’m having a beer now. I’m really enjoying your video. I did pick up one that looks just like yours this morning, August 23 2023, at an estate sale for ten bucks American. Wish me luck!
i am so sick of copyrights
Panasonic boombox from the 90s palgged with switch issues. The only way test to check the control board is ok, is using the remote control. Panasonic systems used just a resistor array and a three wire reading for the whole front panel. Instead of reading ON / OFF it detected different small changes in the voltage line as different buttons have a different associated resistor (different value). Guess what ???? as soon as the switches started to wear a bit an develop some ohms, system went crazy, as the voltage generated by one buttont shifted into other button value. Giving Play, turned radio. Pressing stop would rewind and so on. Pretty common failure mode. You need to replace all switches or at least the most used ones. As per the transforme output, dont worry. It could be two thing. The voltage goes down while loaded (boobmx on) or, boombx accepts more voltage than the one provided by batteries to put more ouput power on AC. This sounds rare, but many 80s boomboxes did it that way. They have TWO ouput power figures. Running on batteries was the lower one and running on AC the bigger one. but you need to regulate certain parts like the logic control and motor. The amplifier part does not need regulation.
My name is Paul too👍
That's not copy right music
Why don’t you just burn a cd and tape of non copyrighted music for testing purposes?
what are the chances of that ! .. I just got the same hitachi with the power not working ! .. I know where to look 1st now !
I absolutely love when you do these fixes it gives electronics a second lease on life I do the same thing keep up the good work
If the remote had worked the whole thing could be switched on with that.
Great fix Vince, I didn't know those tactile switches were such a common fault , so good fix and great comments. I learned something new that will be sure to help me in my Mr Fix It jobs. So a big thanks all!
Looks like Vince finally fixed a faulty switch!
Actualy if you unscrew the CD module you will be able to disassembly the whole unit pretty easy, sometimes there are screws under door. The LED is not dual color (it would had 3 leads), but it can be (unlikely) bi-colur (reverse polarity is used for other color). The construction is relatively good. The switch is momentary (the name is TACTILE Switch) it costs barely 5 cents. The repair went flawlessly. Perfect job Vince.
Would love to see that lady seeing the fine job you did on her radio. Must be great having something she's used to back working like new!
Well done lads! Enjoyed watching you both figuring out the faults and getting it going.
Such a small fault leads to such a big problem. Great to see this video!
You should go round bootfairs and film it grabbing bargains and faulty items.
My mate Vince? More like my SOULmate Vince!
