Question about Protron PLTV-32 Television

1 Answer

Audio on the low end is not linear

Turning the volume down to the last mark of very quiet, the 2nd mark the volume jumps, not real loud, but not what the next level of quiet should be. It has been this way since new, just really bugging us now. Is there any kind of software refresh in this TV?

It sounds like you've done quite a bit of troubleshooting, which I applaud you for doing. Have you tried power cycling the TV? Simply turn off the TV, unplug it (and any components connected to it), then plug it back in and turn it on after a minute. See if this corrects the issue. If it doesn't, then I would recommend calling our Product Support team to schedule repairs at:
U.S., Canada, & Puerto Rico - 1-800-305-2204
Mexico - 1-888-882-7326
daily from 7 am - 12 am CT.

I bought a Sanyo model DP55360 Nov. 2010 that now has started turning itself off after a short time, when I restart the tv it shuts off even sooner than before which continues until it will not restar

When it does come on, before it shuts down, does the volume seem to fade real low first? If so its a problem in you main board. IC1670 is bad. Its pretty much a voltage regulator for the audio tract.

Commercials come on so loud we have to mute it what to do

Noting I can think of other than not wathcing a channel without commercials.

Commercials' volume is purposefully pumped up, that's a well known fact,

The TV doesn't make a difference between what's commercial and what not though - it just plays whatever stream level is being supplied.

Well, the amplification may not be and probably isn't linear, but regardless, the point is there's nothing you can do on the TV's end.

Another TV may be a bit less obtrusive, but commercials will always be louder and if whatever you watch is a bit more quiet than usual and you put the volume up to hear it then yes, ads will sure blow you when they come.

Sometimes the switch is just dirty or the control ic is defective in order to determine the real problem try to check the tact switch or apply a contact cleaner to the switch. If you remove the back cover of your tv try to locate your switch it is easy to locate because it is separated to the main board only wires with connectors is used to the switch, if still no effect then your control ic is defective try to ask a technician to do it for you. and to save you from stress. good day and best regards.

My vizio tv is practically brand new as of christmas, when a movie or even tv is on the voices are very soft and the music or background noises are EXTREMELY loud, so I am always turning the volume up and...

I had this problem with my previous TV (Syntax by Olevia, an off brand). It only happened to me on certain channels, and for certain shows. What is happening is the TV station is broadcasting the audio in Dolby 5.1 format. For some stupid reason, the TV is playing the background speakers (effects) instead of the speaking parts. You get a little bleed-over of the voices into the back speakers, so voices are there but really quiet. Unfortunately my TV didn't have any surround sound options to fix this.

See if your TV has a surround sound option. Otherwise, you will need to connect the TV sound output to a surround sound system that can properly decode the audio channels.

The volume on our new vizio LCD tv jumps from fairly quiet to very loud. Is there any fix for this?

Check to ensure that nothing is pinched up against the volume button on the tv or remote.

have someone check speaker ground to the TV chassis. Your speakers are picking up reverb from the Video Signal.

Low volume on some channels

Well, some TV stations do broadcast at different volume levels. This is very noticeable when watching a TV show and the volume seems normal and then when a commercial comes on, the volume is very loud. They do this to get you to pay attention to the commercial. Another problem might be that you are adjusting volume from both your TV and your cable box. What you should do is make sure your cable box is set to "FIXED VOLUME" and then just adjust your TV volume. Fixed volume will have the cable box output only one volume level, letting the TV do the adjustment. Just go through your cable box setting and look in the audio settings. Hope This helps...

Headphone out jack is really quiet.


If you're trying to plug the speakers into the headphone connector that will happen.
Headphones are having a high impedance and those loudspeakers a low impedance.
That's why your volume is down. It stresses your audio-amplifier and even blow your finals.

Auto volume has little or no effect on loud commercials

This may not be a problem. I believe there is an audio effect used by video production houses to 'boost' the presence of an ads audio and this effect is not picked up by the electronic device's (in this case TV) volume stabilizing software. It is intentional by the makers of the ads.
A work-around could be to try different configurations on your TV's audio settings, such as just mono, or just 2channel stereo, or surround sound - on or off, increasing/decreasing bass and treble levels in different combinations.
The down-side to this is to get a comfortable, uniform level of volume across the board, you maybe sacrificing some sound quality - but, as with our eyes, our ears adjust well quickly (hence don't listen to too loud sounds) and what you may not like now, will sound ok tomorrow.
I can't tell if there is a fault or not, but this may help if you "trial" some options.
