Re: Emachines E642, no speakers detected
You need a scope.
Because its audio problem. You need to see the output and where it stops.
Try with the dmm and see if you got mV on the chip.Just cook it! It's already broken. -

More Lo-Fi speakers and another DIY surround repair.
The patient this time: a pair of Philips F9217L-50R speakers from a budget Philips rack/component system from the '80's. The system belongs to my brother in-law… or actually his parents. However, they didn't want it when they moved houses and he liked it anyways, so he ended up keeping it. It's a pretty cool-looking vintage system with a wood/veneer cabinet and shelves for records and cassettes. Unfortunately, I didn't get a chance to take a picture of it or get the model #'s (but maybe next time I visit, if anyone is curious?)

Hello everyone,
I am working on an ASUS ROG G513QY laptop with RX 6800M dGPU.
Originally, this laptop was completely non-functional. I replaced the motherboard (part number 6050A3254002-MB-Axx), and with the replacement board it started working fine.
For a long time, the dGPU worked perfectly stable. I played several hundred hours on very demanding games such as Cyberpunk 2077 without any crashes, instability, or detection issues. Performance was excellent and there were no warning signs of failure.
However, after some time, the replacement motherboard...08-25-2025, 06:09 PM -
Currently trying to connect pc speakers to 2015 vizio tv, tv has no 3.5 headphone jack. Does have rca audio out, tried connecting thru a Y rca to 3.5 cable but getting odd results(probably just need a dac for decent audio, not sure?) not too educated on audio. With that hookup I'm getting 2 problems, can't get the speakers to increase in volume so it's very low even when turned up and when using both tv and pc speakers the pc speakers only put out the music part of the broadcast and not the vocals/talk of the program. Have you run into this before or know what it might be, Thanks.

Hi guys,
I have a set of Logitech R20 speakers, one of the speakers wasn't working, so I took it apart & there was no continuity or Resistance when probing the Tinsel Wires. Plus looks like the speaker was exposed to liquid as there's rust on the metal speaker frame.
Just in case, I removed the other speaker and installed it in place of the damaged speaker to make sure the PCB of the damaged speaker was ok & it seemed to work fine, so it looks like it's just the speaker for now.
Printed on the back of the Logitech speaker is;
