    SHARP lc-49cug8462ks NO Sound through the speakers

    Hi,
    Got Sharp lc-49cug8462ks with NO sound through the speakers.
    Sound is working fine on the headphones.
    In the TV menu can't change from HP to HP+TV.
    Any idea what's wrong?
    Thank yo very much for any support.

        Maybe try heating up or cooling with freeze spray or upside down can of duster your IC chips on mainboard with a hairdryer, see if you get sound even for a bit.

          Good point.
          I'll try that later.

                I downloaded the firmware from manufacturer website.
                Updated the TV.
                Got sound working now but got two pictures on the screen instead of one

                      Makes me thing that that firmware is buggy, I would email sharp, maybe they will send you the firmware, hopefully they have one that works correctly if it is buggy that is.

                        Maybe try the firmware update with a different usb thumb drive.

                            A2442 - No sound over internal speakers and no video playback
                            by soeren
                            I am facing a strange issue, I don't have any sound over my internal MacBook speakers and also the video won't start. If I change to my head speaker or via HDMI (speaker on my external Display) the sound works over the head speaker or Display and also the video starts (ex. youtube).

                            All happened after the battery ran out of power overall several days when I was on vacation.

                            I tried to remove the battery and then reconnected the battery, and then the MacBook Pro 14 2021 won't accept any power from my power socket. Then I removed one speaker, connected again the battery...

                            by ChaosLegionnaire
                            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...

                            Telefunken L70 speakers, one has a nasal sound with less bass
                            by Zonzi
                            Hi everyone !


                            Once again I have an issue with old stuff I found for cheap, guess I have a taste for these.


                            I bought these two Telefunken L70 speakers for 20€ (https://www.radiomuseum.org/r/telefu...r_box_l_2.html), and they are in a superb state, component-wise. The box is scratched but I couldn't care less, I'm interested by whether it works or not.

                            They do work, and have a really nice sound, but one of the two has a problem with its 8" woofer. It's got practically no bass, and the mids are really pushed...

                            Hello to the forum.

                            My name is Christos, I am new to the forum here and i am posting from Greece.

                            So i have this old German sound card from Marian, called Trace Alpha. To be exact i have 2 of them and i use them professionally for my small FM radio station here. The first one works like a charm, but the second one does not work at all.

                            To be more specific in the same exact pc with windows 7 (i even tried 32bit) the one works while the other doesn't.

                            So i tried asking for a schematic from the company and they would not give me one. Instead they...
