RCA F19421 TV - Low Volume Problem

Our RCA F19421 19'' TV started having a problem with low volume level a few days ago. With the control indicator turned up all the way, the output volume is about half of what it was before. What could be the problem?

SOURCE: Why does my RCA TV cycle through channels on its own?

this is the same type of problem happening with other rca models and I know it is the EPROM CHIP but why this is failing is either because of design flaw , dirty enviroment that they were made in , to much voltage or current to the chip or too much of a draw from the chip causing it to fail . Or even a random frequency from the IR sensor or its circut I'm still investigating and testing.
leave the tv unplugged for at least 3 weeks durring this time resolder any solder that don't look good , I did this and it lasted for about 6 months(always plugged in to the wall) before it started doing it again. model # 27v412t

SOURCE: Low volume output and very low volume when digital

if you are using a digital converter along with a standard tv , you have one volume level low making the unbalance sound a humming sound, if it is directlly into your tv, check your settings on your tv bass, trebile, by the sound of it you probably have a digital converter , if this is so, raise the volume of your TV to mid point that raise /lower your volume on the converter and it should be fine, also make sure your ouput channel is not the same as your broadcast channel in your area, example,,if your area uses channel 3 for broadcast, set your rf output to chann 4 , and vice versa.

Low level inputs are designed to take signals directly from an amplifier's "sub out" connections. That way the KLH amplifier will use those signals to produce sound and the volume can be balanced between the main amplifier and the sub amplifier using the sub's volume controls. Depending on your amplifier and sub, that is the best way to connect them. However, be careful running the RCA cables since the low levels are more subject to interference. Keep the runs as short as possible and use high quality shielded cables for the interconnects.

I have an RCA F19421 Tv and can't take off the lock on my channels cause I dnt have the password.can u help me?


Hello
You must have its original remote control to unlock it. If you haven't one with you now, try to get a new one of just gather it from any of your friends or relatives who owns the same model number RCA tv; just to unlock your set. After unlock, you can use any other universal remote control. To unlock your RCA TV, just follow the proceedings given below. One amoung them will surely unlock your TV.

Most RCA TV sets use a four digit code to control the v-chip. The code reset procedure is different depending on the model. Try each method until you find one that works:

1. Hold down MENU on the remote and VOLUME DOWN on the TV it's self at the same time for at least 4 seconds. The set won't say so, but the lock will be unlocked

2. Hold down the 0 on the remote and the VOLUME DOWN buttons on the TV its self at the same time for at least 4 seconds. The set won't say so, but the lock will be unlocked

3. Hold down the MENU button on the front of the TV and the TV button on the remote at the same time for at least 4 seconds.

4. Hold down GO BACK on the remote and MENU on the front of the TV at the same time for at least 4 seconds.

5. Hold down EJECT on the front of the TV and the MENU button on the remote at the same time for at least 4 seconds.
Depending on the model, one of the methods should unlock the V-chip. Now, if desired, you can change the settings on the V-chip by going to the MENU and going to PARENTAL CONTROLS, or on some sets, going to MENU and then going to TV SETUP, then to V-CHIP SET.

Hi,

The audiolevel is much to low for a headphone.
You really need to use a headphoneoutput ( if its there) or a headphoneamplifier.
You tried to connect your headphone on line-level outputs.

Have you used the remote that came with the TV to raise the volume? Often, when there is more than one remote, one of them is set too low and all you need to do is use the remote that came with the TV to raise the volume level. Good Luck!

Volume at 100% and sound too low to watch dvd tried with several dvds and volume is too low


Hi,

Just cross check the volume settings in volume controls. All the sliders should be at max level specially Volume Control and CD Player.

If it is fine then there is some thing wrong with the media you are trying to watch or can be problem with audio driver.

Volume is very low


Use the satellite receiver remote control to adjust the volume first. The receiver itself offers volume control and you probably have that turned down. Then you are trying to raise it with the volume control on the TV. This is raising the TV volume, but there isn't much sound there in the first place. Use the receiver remote, and you will probably see a volume bar. At some point it might say something like "best stereo" or a star might appear. If that happens leave the volume set there, otherwise just raise it all the way. Then control the volume with the TV remote, or program the DirecTV remote for your brand of TV, and the volume button should control the TV then.
