Defective from get-to...no 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 get-to...no 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

Re: Defective from get-to...no 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.

if just running HDMI cable try adding audio cables too, check all your volume and mute settings in the system setup.
If you have audio on most channels, but have silence on some or all of your local network channels, you may have the Secondary Audio Programming (SAP) turned ON. Complete the following steps to turn off SAP.
Press the Settings or MENU button on the digital remote.
Result: The Settings screen displays.
Choose from the following options.
Press the Select button.
Choose SAP Languagedisplays
Use the left or right arrow buttons to choose the English setting and press Select.
Scroll to the Language option, select Audio, then select the option labeled Primary or the one labeled English.
If the above quick fix doesn't work, there may be a problem with MTS, Stereo, or another SAP issue. Try the following:
Verify in the program listing guide that the program has MTS, Stereo, or SAP features.
Check to see if the MTS, STEREO or SAP light on the TV or VCR is on.
If the light is not on, try the following:
Push the MTS, STEREO, or SAP button on the TV or VCR.
Adjust the fine tuning on the TV set to restore the stereo or SAP.
The audio signal connection between the processor and the amplifier chip is loose or defective. You need to open the tv, follow the wires from the speakers to the amplifier board and then check all the others that plug in there. Fix or replace the faulty part.
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.
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.
Sharp TVs often require you to press the TV Tuning preset key which is a yellow function key. Setting Up Your Sharp TV Turn on your TV.
On your Tune In remote, press TV and release.
Press and hold Set until the green light on Tune In blinks once, pauses and then blinks twice. Now release the Set key.
Enter the first three-digit TV code for your Sharp from the list which follows: 093, 165, 039 These codes are listed in order of popularity, and the green light will blink twice if you perform this procedure correctly.
Aim Tune In at your TV and press Power. Your TV should turn off. If it does not, repeat steps 2-5, trying each code listed in step 4 until you find the one that operates your TV.
Now Test Your TVWhy test? Many times more than one code appears to work. Testing is desirable to be sure you have the correct code for your TV or the other devices you are setting up.
Press the Power key to turn on the TV, then press mute, channel scan ("CH") and volume ("VOL") keys. Tune channels 7 and 11 by entering the number followed by the Enter key.
If your TV does not pass the test, return to Step 2 at the top of this page. Enter the next three-digit code and repeat the process.
Resetting the TV If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:
NOTE: Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time. 1. Unplug the TV power cord from the power outlet. 2. Unplug any connected devices (DVD, Set-top boxes, etc...) 3. Press and hold the TV power button for five seconds. 4. Plug the TV power cord back into the power outlet and turn on the TV. 5. Open the on-screen menu to confirm that the TV is responding again. 6. Turn off the TV and reconnect the devices. 7. Turn on the TV.

Go in to the user menu and find where the Auto Channel Setup is located. You can consult the instruction booklet for your TV set. Try this and see if it works. If it does not then there are a number of areas in the set where there can be some defective components.
The tuner is controled by the uPC system. There are a number of interface circuits involved for the channel control. Problems in these areas can cause the channels to not be able to be changed.
