Question about Protron PLTV-32 Television

Defective from sound on local channels

Have been trying to get this TV fixed since May 2007. I followed the required "return" steps only to have absolutely no customer support on the other end at Protron. Each time I call I am told to call back in two weeks. Today, I was actually hung up on. My advice to anyone looking at a Protron TV purchase....don't. This company should be reported and forced to close.

Re: Defective from sound on local channels

I had the same problem. Do you have a cable box for digital TV? do you have a remote from the cable company? that is programmed to control the TV? get the cable company to unlock the sound control from it (a 3 number code) put your sound up to maximum if you can if you hear faint sound repeat above you should be able to hear the tv then then go to the sound settings and adjust as needed get the cable company to check the box in case it has been zapped by lightning good luck

Re: Defective from sound on local channels

This unfortunately is an all too common problem, customer after service is poor unless you are face to face with the supplier as it's harder for them to fob you off, but even "bluechip" so called companies are the same in some cases, as i had the same truoble trying to get a 3 months old LG LCV TV rectified, after around 8 phone calls, 10 e-mails and over 6 weeks later, TV return 'no fault found and was damaged in transit. What can you do?

My sound disappears


there are so many reasons why your TV won't bring out sound. You need to troubleshoot first, in order to get to the root of the problem, before a solution can be proffered.

First, connect a DVD player to the TV, observe if there is going to be sound. If there is still no sound after connecting the DVD player to the TV, proceed to the next step. "The reason why I asked you to connect a DVD player to the TV is to confirm if the problem is simply not from the audio cord connected to the TV."

Second, get an headset, connect it to the earphone jack of the TV and observe if there is going to be sound. If there is no sound, then it is glaring now that your TV is having a defective sound card/IC that's why it is not bring out any sound. (Note that connecting an headset to your TV is optional because not all TV's has a space for headset). "The reason why I asked you to connect an headset to the TV is to also confirm if problem is not from the TV speaker. Though TV speaker problems are rare but sometimes, the TV speaker might be defective or the speaker wires may have loosed contact or cut into two, due to one reason or the other. But if the headset doesn't bring out any sound from the TV, then it is not so."

If none of the above seems not to be the cause of the problem, then the above troubleshooting has confirmed that the TV has got a defective sound card/ic. The sound IC/card of the TV has to be replaced for the TV to bring out sound again.

To be honest with you, replacing or fixing the sound card/ic of your TV requires the ability or experience to do so.

Now, if you are convinced you can fix or replace this yourself, please reply so that i can help you further. And make sure you troubleshoot first, before getting back to me.

I accidently pressed the channel button on my remote instead of the volume button. I now have no picture or sound. I tried returning to the previous channel but it keeps saying " channel not...

Not familiar with your model, but the problem sounds generic. I am guessing your set is hooked to a cable tv box, and that is where you need to change channels. I also guess that when you changed channels on your TV you probably moved from channel 3 to either channel 2 or 4 and the cable tv box is not sending to those channels so you lose picture and sound. Now, more guessing, you try to put the channel back to 3 on your TV, but still nothing happens. OK, if close so far, there are a couple of things to try. First, be really sure you are actually going back to the same channel you started with. Assuming you don't actually have the signal coming in on an auxiliary line-in and that you had it coming in on a channel, you may need to reset the presets on the television so that it recognizes the one important channel the cable tv box is sending out -- just follow your television menu to select or set channels. There is one more possible easy problem ... I have seen this one happen, after getting the channel correct and reset, if it still doesn't work, you mght need to turn the set off and wait one minute, then turn it back on WHILE the cable box is ON. This can cause the set to RE-Latch onto the cable box signal. It really doesn't sound like something is truly broken or needs replacement, sounds more like a user error. If your set is still under warranty, just call the Panasonic hotline (find it in Google, and they may be able to walk you through exact instructions for your model). Hope this helps.

When u put a dvd in it shows coloured,but regular tv channels shows black and white

Most likely the cable between the cable/satellite box and the tv is not fully home. Push all the connections firmly home and try it again.

The unit is telling you to run autoprogram to program in your channels, make sure also the TV is in cable mode and not TV mode which is for local channels, If you have cable do a autoprogram so the set can program in channels. Auto Scan is the same as autoprogram.

I know this tv has digital capabilities, so i don't need to get the digital box, what do i need to watch my local channels? i have directv but does not include local channels (ie. fox, abc, nbc).


To tune the local channels do the following.

1 Press the MENU key on the remote control to
display the Main menu.

2 Use the CURSOR "UP" or "Down"
keys to highlight
Manual Channel Search. Press ENTER.

3 Use the CURSOR "Up" or "Down"
keys to select Cable,
Air (Antenna), or Digital Add-On.

After the search is complete, the HDTV will exit the
menu system and return to normal TV viewing.

IMPORTANT FACT: This HDTV maintains only one database

of digital channels. Therefore, when you search for

cable channels, the database of antenna digital channels

will be deleted. You will only be able to receive those
ClearQAM channels your cable company provides.

NOTE:"Not available" will appear on the screen

when an option is unavailable.

Light in on but the TV won't turn on

Try the following steps below:
- replace the battery of the remote control and then turn on the TV.
- try using another remote control of the same model (If there's another one like it)
- press the channel up/down button to manually turn on the TV or any button to activate it.
- try plugging it to a 110 volt transformer. (if your area uses a 220V power supply) Most TV's today are using autovolt power supply. (check the back to see if it says " 110-220v")

If you've tried them all, the power supply inside the TV is defective. Usually the Power Regulator I.C. is defective. It maybe also be due to a bad diode or transistor within the power block. Needless to say, you'd need to bring the unit to a service technician to fix it. And do not attempt to open the back and try to fix it yourself if you don't even know what a diode is.

And it is definitely not a busted fuse.

I have the same set, same problem with one of my MOTOROLA boxes, but not with another. I have a SONY TV that works fine with this new MOTO box, but the new VIZIO does not. The audio is coming through the HDMI cable just fine, and the fact that it works when you cycle power on your TV means it's the SYNC between the TV and the BOX. I have the identical problem and am taking back the MOTO box for another one. I spoke to VIZIO for about 45 minutes trying different things. They think it's the MOTOROLA box, COX (my cable company) thinks it's this particular box, who knows.

TV gets stuck on channel, won't advance past channel 7.1

Try doing the Channel Search again. See if that helps.

If not, sounds like the Digital Board could be defective. Since this TV is brand new suggest calling your local sharp authorized service center to replace that board under warranty.
