This really helped me in determining the audio switch IC on audio output in my laptop (marked AH2) that I wasn't able to find anything about. Now it seems to be ISL54405IRUZ
I probably managed to blow it by connecting a speaker output from another device to audio output jack of my laptop by accident. The speaker output was only connected to left output of the laptop, so it is now grounded, probably inside the mentioned IC. The right output works normally. I am going to replace this IC.

Good morning everyone,
I'm trying to repair an onkyo ht-r390 that has no sound output, despite the volume being at maximum, the rest seems to work; the video output signal (coming from an hdmi input) is present, but the audio is absent. Similar situation if I send an audio signal from any input I have no output.
The firmware reported is the following:
M:1.00/11107BLP
D:?.??/????????
O:1.00/11107AL
The DSP firmware given the question marks seems corrupt.

I have bought this Zener Diode for this project what size and wattage resistor value do I need to use to get near 50 watt output
I bought this from an eBay seller but unfortunately they only had one
I bought three from Vetco Electronics these are Sylvania ECG5185A 9.1@10w A to Stud what size and watt resistor do I need to use to get near 10 watt output
I bought three of from them to also make battery packs with this output power limit in mind
I want to use this battery pack and turn it into a 9.1 output battery pack output to eliminate using 9 volt battery... -
Hello, this might be embarassing since I consider it a dumb question but keeps me kinda stuck sometimes in my journey.
I want to know if there is any post in this forum which explains my questions. A) When, where and how do I know when X voltage line is input or output. Example:
I'm battling with this IC to understand it's voltages. It's from non-turning-on Lenovo Ideapad 3 15iil05 - NM-D461.
I see some lines like +5VL / +5VALW / V9B+ / +3VALW being okay and some others like 1.8VALW / +0.6VS / +2.5V_DDR. I just know that some of them are bad or missing,... -
Looks like I may need a little help from the PSU experts (or anyone really!
) I have a Corsair CX750M (Model 75-002019) that I picked up for free about 4 years ago. This is the PSU:
So here’s what’s strange about this one: it appears to work normally (normal output voltages) and any PC is stable with it. However, after a while (typically 10-20 minutes, but time can vary depending on the load), there is a sweetish smell of burned magnet wire insulation emanating from the PSU. Upon opening the PSU after this happened (many times), I was able to confirm... -
I have here a Magnum IA.100 which belongs to my parents.
The unit powers on & when the relay kicks in, you get a pop from the speakers (this might sound weird but is usual behavior for this amp). However, you get nothing coming through it from any of the inputs & no pops and crackls from any of the controls.
Because of the sound from the speaker when the amp turns on I have assumed that the output section probably works but I could be wrong & I'm not sure how to test that side of things further.
