Unplug what ever is plugged into the televsion jacks and see if it is still buzzing. If it is, this is an internal issue. If it not, then it is a bad cable or connection of outside interference.

SOURCE: I've lost the sound on my Sylvania 24" television.

hi, OK FIRST......Both the cable box AND your TV can lock up and cause NO SOUND....except for that hiss you're hearing.

So, UNPLUG BOTH UNITS FOR FIVE MINUTES, and then plug them back in and see if you still have the sound missing....

NEXT, if there's no sound, look on your remote control for the MTS button....if you press it and it says SAP on your TV screen, keep pressing it until MAIN pops up on your TV. That's for MAIN sound, SAP is for Separate Audio Programming.

Also,why the TV does not bring out sound when on TV is because the TV region does not work in your country where you are right..

In other to fix problem like this,What you need to do for the TV to work in your country, you will need to convert the TV to a region that will be able to work with your countries region.

TO fix this,please contact a specialist repair man to fix it up for you.

Also,In what position is the switch that can switch between internal or external speakers? If you connect any of the line audio outputs to a VCR or DVD, do you get any sound at all? If all of your tests to check Audio do not work, then I'm afraid you will have to have a competent technician look at your set. Considering it is a 38" Widescreen CRT w/HDTV, it could be worth fixing.

Hope it helped.

No sound on channels

Its a 19 inch set which means:

1 If a single speaker put ear to set to see if any sound or a low hum can be heard from it at all.

2 If set has a headphone jack on it see if sound there

3 If above fail either the speaker/s are bad or you have a audio circuit problem which on a set of this size is not cost effective to repair------------buy a new set.

Some channels have no sound, other channels are ok, one channel sound goes in and out....what do I check for?

Problem :
some channels have no sound.
Theres nothing wrong with your TV, is a misconfiguration of your Cable / Satellite box.
Check in the Setup of your Box the language option and select "Channel default"

How can I input my sylvania 27" into video 1 or video 2 without the remote? The menu does not offer a game option nor a video 1 or video 2 option.

Here are the instructions for the TV.
They do not say how to select Video or Game mode without the remote. Try connecting a vcr or game to the input and do the Channel Pre-Select process to see if that will pick up the input as part of the Channel Scan. If it does you will be able to get to Game or Video using the channel up/down buttons. Another option is to get a replacement universal remote that has a code for your TV and will assign a button for Game or Video.

Sylvania TV stuck in Game mode remote no longer works

go up to your TV and go into the menu. Go to the channel selection and run the auto select for channels. This will take some time but the TV will end off the first channel found, the only thing is you cannot get back into video mode without the remote
