The tv has sound but only if it the volume is all the way up and it is very scratchy. I thought it might be the speakers but when it is hooked up to other speakers it had the same result. Possibly the sound board?

First things to do is check the volume controll if working or not.Then if good,check the wiring from the amplifier to the speaker,check also the speaker if good,if that parts is good,check the amplifier try to check the input signal of the amplifier if there's a hamming sound comming from the speaker,then if the amplifier is good,trace the signal sound of the amplifier from the board of your TV.Step by step process to find where is the problem coming from.Thanks!!!
for using FixYa. Please reset the TV by unplugging the power cord for more
than 4 hours and plug it back in. Now check that the sound is coming normally
from the set. You’ll need to also check these parts--- Breakdown
or overheating of some components of amplifier, wiring, speakers, function settings,
power supply and sound detector inside the signal IC processors are fine.
Go to the
on-screen-display and make sure you are set for stereo audio. Please check that
the on screen display is set up for internal speakers and stereo audio. Also,
check any other settings that may have gotten disturbed accidentally. Make sure
that all the settings are correct and that the internal switch on the back is
set right. Use headphones and check if you’re getting sound through them.
You’ll need to check that the issue is with the speakers, wiring or the
the issue is not resolved then check the audio chips are fine. If you’re
using RCA cables then switch to HDMI and vice-versa. Please do
accept the solution if the issue is resolved or else revert for further
assistance. Thanks Rylee
Are you referring to sound using the Tv system or an extraneous sound system. Do you no sound.......or distorted sound. Have you checked all speaker connections if this is a unit that has been in place for quite some time. Age can do strange things to terminal connections which may need either resoldering or cleaning up. Try using other speakers that you know give good sound output on another system. It could be that the speaker diaphragms have dried out and lost their elasticity.
Ask service person what the capacitor fixed? Did he/she verify full operation before returning, including sound? Did he/she remove any speaker wiring during the repair process? If so, he/she may not have re-connected all the cables. Assure the tv is not in "mute" mode or has the volume set to zero.
RCA HAD A CERTAIN MODEL SERIES THAT HAD A REALLY BAD DESIGN,,IT SEEMS THAT SOLDER CONNECTIONS STARTED BREAKING LOOSE AND DEPENDING WHERE THEY CAME LOOSE,,YOU WOULD HAVE PROBLEMS IN THAT CERTAIN CIRCUIT..TO DETERMINE IF YOU HAS THAT SERIES,,WE WOULD NEED THE CHASSIS # ON THE BACK...
IF THE CONNECTIONS CAME LOOSE IN THE VERTICAL CIRCUIT--THE PICTURE WOULD CLOSE UP ,,IF IN THE TUNER SECTION--YOU WOULD LOOSE CHANNELS ,,IF IT WAS IN THE AUDIO SECTION--YOU WOULD GET CRACKLYN SOUND OR NO SOUND
ONE THING YOU CAN TRY--PUT IT BACK IN THE TV MODE,,GENTLY TAP ON THE CABLE CONNECTOR IN THE BACK OF THE SET AND SEE IF IT CLEARS UP,,IF SO YOU HAVE THE CONNECTION ISSUE--WILL NEED A TECH..GOOD LUCK ..TUNICA
On the back of your set there are 2 switches that tell the tv whether you are using the internal speakers or the external speakers.
Make sure the switches are set to internal so the speakers in the TV receive the sound signals. If they're set to internal maybe the internal speakers are bad. Set the switches to external and hook up external speakers to the speaker terminals on the back of the TV. If neither setup works then it sounds like an output transistor or related parts.
TRY A DVD PLAYER TO ISOLATE THE BAD COMPONENT. IF IT WORKS CORRECTLY THEN THE PROBLEM IS IN THE TUNER AUDIO OUTPUT SECTION, IF IT DOES THE SAME THING THE SPEAKERS IN THE UNIT MAY BE DAMAGED. TRY TO USE A VCR TO GET AUDIO OUT AND RUN THE SIGNAL THROUGH A STEREO WITH STEREO INPUTS AND LISTEN TO THE SOUND IN THTAT WAY
First unplug the a/v receiver and then check tv to see if the audio output is on or internal speakers. With the a/v rec. you should have chosen the variable audio and not leave on int speakers. If this does not work unplug set for at least an hour and try again. You can get additional info from www.ctechnicians.com
