I'm trying to fix my Desktop Acer Aspire M3100,(Vista OS)because it is only playing on one channel(left side) it is a 7.1 integrated that I only ever use on stereo,sometimes it wont work at all for about ten seconds then the left channel cuts back in,I can just barely hear the right speaker if I listen carefully when doing a sound test.yet it works fine with headphones plugged into the front but if I use the front headphone plug for my speakers it wont work,Ive tried everything I can think off to fix this including changing drivers,contact cleaner ect... Can anyone solve this mystery for me?could I use a sound card to get around this? Any help greatly appreciated.

Re: One channel wonder?
Maybe it's poor solder joint on the actual speaker? -
Re: One channel wonder?
Did it just suddenly develop this fault or did it come on over a period.
Are the internal speakers plugged in to the mother board correctly?
Can you try some other speakers on the motherboard.
Can you take the speakers out and try them on another sound source.
What motherboard is it?Last edited by selldoor; 06-16-2012, 07:10 AM.Please upload pictures using attachment function when ask for help on the repair

Re: One channel wonder?
If it's like a Realtek chip that supports jack retasking try using a different jack as the stereo output.Comment

Re: One channel wonder?
Yes the fault just appeared one day,Well I lent it to someone and this is how it came back? I'm using an analog amplifier and speakers that work flawlessly on anything else.Mother board ID F690GVM,I don't have a service manual for the MB but I am presuming that the plugs are all in the right place? Could it be oxidation in the output box,the green output plug feels a little loose as well,would it be safe to unsolder it to check it out?HP P6-2203a desktop,AMD CPU A8-5500 with Radeon HD7560D,3.20Ghz.

Re: One channel wonder?
I dont know the motherboard at all - looked online but couldnt see much
right at the edge on one picture somethingwas labelled speaker but couldnt tell what it was. Perhaps some pictures would help us?
If you have confident at soldering Id say give it a go will you be able to see any
better if unsoldered?Please upload pictures using attachment function when ask for help on the repair

Anyone run memory speed tests with an old X58-based triple channel 1st gen or any other >2 channel board? The one I have is a Gigabyte I think.
Anyway I had four 4GB DDR3-1333 modules in the 6 memory slots and got around 11GB/sec memory speeds assuming that it went dual channel since it didn't have enough modules for triple channel. Now I stuck in two more 4GB modules, but they are DDR3-1600. I'm still getting 11GB/sec speeds according to memtest86...
Just wondering, anyone do memory speed analysis on these triple (and higher) channel memory boards? Are there any... -
OK, this one dates back to 2015! I thought I had posted this, but realized I didn’t when I posted a picture of something else. So here it goes…
Back in 2015, I bought a pair of RCA WHP141 wireless headphones at Micro Center for $2. I even mentioned it in the best cheap/free scores thread right here. Just forgot to follow up with that.
As mentioned back then, these are (were) 900 MHz FM wireless headphones. No modern day Blutooth or anything like that. I knew they wouldn’t be great headphones or even that good… but the price was right!
So let’s take...

Good day ladies and gentleman!
I am currently trying to repair a Grundig Vision 9 37 9880 T USB LCD TV for a friend that has a weird audio problem. Basically everything works fine except for the heavily distorted sound when the Subwoofer module is connected and there is a buzzing sound coming from the PSU PCB.
This seems to be a rather rare TV so there is not much prior on topic help to be found however a service manual is available at the usual sources (Electro Tanya i.e.).
I think the PSU buzzing comes from one of the coils near the bridge rectifier but... -
Hi friends
I have reverse engineered this tester, schematic is attached and is complete except for capacitor values. These testers annoyingly have no model number but they are the ones you find on the first page of just about any website if you type in "18650 4-channel tester". There is also a 2-channel variant and a newer 8-channel variant. They are very cheap (about £15) and can measure voltage, current, internal resistance and capacity. They have a multicolour display for all these statistics. They also have terminal blocks so that if you want to use a breakout board... -
so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol! 
i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...
