Hello.
You can see above that I replaced the zener diode. But whenever I plug in the adapter the SS24 SMD above the zener shows reading negative -6.01 V. But this time the zener diode does not get hot. I am not sure now what could cause the problem. Please help me out here.

Thanks for the reply. I have a multimeter but I do not know how to test it. Although I can replace it but I don't know where to search for it. Yes, I can solder.
I don't know how to check that. But the SMD above the zener diode is SS24 and I get negative readings when I attach it with the...
Hello friends.
I am posting here after very long time. Hope you all doing great.
Recently I received some devices known as Cloud Computer. I don't know who the manufacturer is but the concept of cloud computer is great regarding this pcb. Well here are the pictures of the device (outside and...
Hey guys, sorry for replying so lately on the same issue again.
So, this is what is happening again -
I had a very faulty Transformer which caused pain to me since the last 2 years in a row. The same issue occurred to my speakers again. So, I tried to replace the AC transformer with the DC...
Hello.
I am posting here after a very long time. In my previous post, I had a solution regarding the IC being faulty. Right now I am just asking a simple question here.
Is it okay to use an 12v adapter DC voltage instead of 12v AC in the PCB power supply section? (Picture attached below)

Hello.
I am posting with a new issue again. Hoping to get some clear solution regarding the replacement / repairing of the Casio fx - 991MS scientific calculator.
Here's the story -
A while ago my calculator stopped showing some digits on one side of the LCD panel and some blurry digits on...
Okay, so guys, I repaired the buzzing / humming sound problem by repairing my old transformer and replaced it with the new one. The new transformer had cheap copper wiring and the plastic core shell melted because of the heating it produced inside the primary and secondary winding of the...
Hello.
I am posting on this forum again after a long time.
Previously I have posted here and here. And this new problem I think is related to the old ones.
After repairing and solving both the problems, I am facing a new problem. Yes, the buzzing / humming sound coming out of my speakers...
Hello.
I am posting in this forum after a long time. Previously I posted my issue with the IC on a cheap PCB built for a 2.1 Speaker. You can read the post here.
Anyway, I figured that my old transformer started to create some buzzing noises which directly came out of the speaker boxes (from...
Hello to all.
It just happened like magic, but I can hear the speaker sound again. :)
I don't know what happened or what triggered, may be the power input or audio input, though I did not touch anything else. But with the same voltage output on the KIA6268K ICs, the amplifier is now on. I am...
Hey guys.
I am posting after a little bit thorough market research. I found another company making the D6282 IC. It's branded as - KIA6282K
Here is a datasheet regarding the IC - https://datasheet.datasheetarchive.com/originals/distributors/Datasheets-16/DSA-311851.pdf
I am getting these...
