    improving sound

    a friend is giving me a small 19" f&h lcd tv to fix,the problem with it is that the sound quality is very tinny with lack of bass through speakers (2),it has been with the tv since new,so its not a problem that has just happend,tried all the usual things like adjusting bass/treble etc,no dice,speakers are fine no rips etc,my question is can i use a capacitor in series to bass it up a little?on each speaker,and what would be a suitable one to use?,thanx guys

      Maybe it's by design.

      POOR design.

      A capacitor would create a high-pass filter, but that would attenuate bass and not increase it.
      Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
      For service manual, schematic, boardview (board view), datasheet, cad - use our search.

        Adding a capacitor won't help. replacing the speakers with better ones would help, if you can find speakers that will fit. Your best bet is probably to get some cheap computer speakers (external), and connect them through the headphone out jack. (if it has one - most TVs do)

          Amplifier - bad sound when loud sound on bass
          by eduaqa
          I'n trying to fix a M&S SYSTEM DMC-1which have following problem:
          I'm using FM station to do this fix, I works perfect if volume below around 8 or if bass is set to zero, the sound can go to 20 without problem, but if I set bass to maximum and try to go over 10 the sound comes distorted ... I saw a video on YouTube the person saying about the main capacitors on the power portion, but I disconnect the main transformer and inject direct to the capacitors PINs my bench power supply -23v 0v +23v, but still distorted so I think the problem is not the capacitor neither the transformer...

          what i went through dealing with my mobo with dead onboard sound!
          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...

          Grundig Vision 9 37 9880 T USB (Chassis SR) TV Repair Help - Distorted Subwoofer Sound and overall weird sound waveforms
          by LEECH666
          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...

          Marian Trace Alpha sound card repair help
          by Christos Tsiligiannis
          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...
