Cannot increase the volume on Coby TV

I have regular volume but cannot increase the volume. It shows that you are turning up the volume but the sound does not increase. I have tried unplugging it from the wall outlet and disconnecting the coxial cable but the problem remains the same.

It sounds that the volume to your TV is locked in its service menu. To unlock it, you have to enter its service menu options to unlock it. This is really a skilled work, need sound knowledge in electronics to proceed. Improper data settings done to this window might turn your TV irreparable. It will be best to contact any expereinced service techinician in this matter.

Couple things; You have to "program" the set to receive the analog channels your cable system is still sends out. Doubtful it will be too many. You may have to rent a set top box from them.

Poor quality sound - low volume on Netflix. Everything fine on regular TV programmes.


You have to go to the sound mixer on your PC and increase the volume on Internet Explorer, Microsoft Silverlight also.
To find the mixer try clicking on the speaker on the taskbar.

I have a constant ringing sound coming from the tv. It goes up and down as I increase or lower the volume by remote. As I change the audio option to "Spanish", regular "English" audio comes out on c


The fact it shows on tuner and not DVD means not likely a audio problem--check all audio settings in the set's menu AND if you are using a box for signal look there--has to be a setting.

Some JVC sets (brand indicated here) also had issues with when watching the background audio (like a sporting event) was louder than the people talking and could be interpreted as ringing--This is a setting in the set called something like "Theater" or "Hall"

Has to almost certainly be a setting in the set.

How to increase the sound


Hello,

To increase the sound of your motorola MOTOZINE ZN5 cell phone.

You can increase the sound of your phone in three categories.
1. music volume,
2. ringer volume,
3. keypad tone volume.

To increase the music volume, you go to the multimedia, select sounds, once the song is playing then you click on the up button that is by the side of the phone. You can increase it to the volume that pleases you.

Further means to increase the volume of your phone is that you go to the 'menu', click on the 'settings', select the 'profile', select 'personalize', a page will show up with a list of data that can be changed on the profile, select the ringer volume, keypad tone or whatever sound you want to increase and increase it with the direction button pointing upward that is by the side of the phone.

To increase the keypad tone, from the home page, click on the up button that is by the right side of the phone, the volume of the phone will increase.

Take care

Increase external speaker volume


when the speaker phone is on, try pushing the up arrow, unless you have the button on the side, But I think it is the up arrow while talking.
Also go into regular menu settings, go to sound settings, speaker volume and headset volumes should both be turned all the way up.

Volume increases on its own intermittently


When the volume increased did the display show it doing so as if someone was turning the knob?  I mean did the volume go from like level 15 to 30 or did the unit's level stay constant while the audio volume increased?
Were you alone or sharing the room with a jokester who has a universal remote?
Does this problem occur when the batteries are removed from your remote?
Are you sure the 'volume up' button on the unit itself is disengaging properly after being pressed?
