Tinny sound on tv

Picture quality is good but every so often the sound gets quiet and tinny. Can go on for days then be ok. Have fiddled with graphic equalizer and was a bit better but not much.

You might have a defective audio amp. One thing you can do is try to compare the impedances of the audio amp's left and right channel (tv off) outputs with speakers disconnected. any major inequality in (ohm) reading obviously will tell you so.

Hold a flash light to the screen after it goes off and see if you can see a faint picture. Sounds like your backlight might be cutting off. Repair can be expensive but some of the newer units don't require the entire LCD to be replaced.

We bought a tv for a gift, but the sound is hollow. The sound works, but is very tinny in quality. Is there a setting that will help with this?


, make sure you have a HDMI cord and read the book that came with your TV sometimes you have to change the settings to PCM, it's very important to have the HD cord that controls picture quality and sound

42.1i passenger side rear has power but sound is very quiet and tinny. all 3 other speakers work fine.


It sounds like the woofer part of the speaker is bad, while the tweeter is still good. You are going to have to replace the speaker. Speakers are generally sold in pairs, so it would be best to replace both rear speakers at the same time.

How can I connect my notebook to my TV


In order to display PC video on a TV the PC must have a TV-OUT function and interface, or you need a VGA to TV converter box.
If your PC has TV-OUT functionality, your user manual will tell you this. If you have, Google "Display PC on TV" and you should find some good articles on how to connect the PC to the TV, and how to change the settings on the PC. NB. even if your PC supports TV-OUT, you may still need to buy a converter cable (but not a box).
If no TV-OUT functionality, E-Bay lists some converter boxes from about £15. NB. the much cheaper cables only work on PCs with TV-OUT functionality.

Connecting a laptop to an LCD


your best bet f or picture quality is to use a standard monitor cable VGA or DVI output on your latop like a normal desktop PC, if it's a flat large TFT TV they normaly have one or both of these types. S-Vidia is poor quality compared.

Adjusting your duel display will depend on the graphics card in the laptop and the drivers.

The sound will be simple, a standard 3.5 jack to phono (red and white connections) or to 3.5 jack. it really depends what your going to plug it into for sound, it's it's a hifi then phono is the way to go. you can buy these cables from places like dixons, or any other good electrical retailer, or ofcourse online.

I just bought an Acer Aspire 7520-5185. The sound quality is quiet and tinny - not the "Dolby Digital Live" quality I was expecting. Has anyone got any help to improve the sound?


There isn't much space for decent transducers (speakers) in the case; few units have acceptable sound and volume.
There were once very compact external speakers on the market that fit with the 'portable' nature of laptops, I don't know what is now available; check it out.
