Question about Protron PLTV3250 32 in. LCD Television

1 Answer

The channel keeps moving backward randomly, I checked the remote and even took the batteries out and this was not the problem. I tried using the front panel control but all buttons change the channel backward even the volume buttons.

If the TV is basically behaving like the channel back button is always being pressed then that may indeed be the problem. Manipulating the button on the TV itself (you have correctly eliminated the remote as the possible problem) by repeated pressing of that button and making sure that it not hung up on the chassis does not resolve the issue then I am afraid that a trip to the repair store is in order.

Won't stay on channel. keeps reverting back to next lower channel.


Remove the batteries from the remote and see if the problem goes away, if so the remote has a bad button, that can possibly be fixed by cleaning it. Try these links:

Volume moving on it's own


Either the key/button the TV or Remote is stuck. Just remove the batteries of the remote and try. If same thing continues, do vacuum cleaning of the panel button/switch after switching of the TV, removing the plug from the power outlet. If the problem persists, this might require attention by a qualified service technician.

LG Television 32lh5000 I have started getting a problem with this TV. When I try to change the volume I press up or down on the remote control and the volume just continues to change without stopping...


Change the batteries in your remote, this is a common issue with batteries that are low on charge.
Also if you find that your TV intermitently changes channels and no one is even touching the remotethis is the same problem.

My remote does not work on my tv I have change the batteries but I notice that thre remote control sensor light does not blink or the OPC sensor. We have to turn on the tv manualy and to change channels...


Hello,

If new batteries did not fix the problem, then it means the problem is either from the remote or the TV.

Remote: Check the remote battery terminal, see if its not rust. Also, disassemble the remote, can check the connection between the terminal and the remote board, see if there is no disconnection of any kind.

If after checking and all seems well, then it means the remote is defective. To confirm, borrow a remote, test it with the TV. If it works, then it means you need to replace your remote. But if the remote you borrowed does not work, then it means the problem is from the TV and not the remote.

TV: There is a sensor in the TV that communicates with the remote. If this sensor is defective, the remote won't communicate with the TV.

The TV sensor might have loosed contact from inside of the TV or it maybe defective and need to be replaced.

So do the above troubleshooting and let me know if the problem is from the TV or remote. If problem is from the remote, you need to do a replacement. But if otherwise, let me knows as well.

Good luck.

See if you can change channels by manually punching them in on your remote. If so, you need to go to your menu, channels and autoscan your channels again. Then you should be able to use your forward and backward buttons again.

Tv won't stop changing channels


You need to isolate the problem.
1) Unplug the set for a few seconds then plug it in.
2) Operate the TV with the control/buttons on the TV. (Channels etc)
If the TV operates correctly then do the following.
3) Try operating with the remote unit. If the problem returns then it's the remote failing.

Sometime remotes can be reset.
Try this;
Step 1- Pull the batteries out of the remote and leave them out until Step 4.
Step 2- Press and release each and every button one at a time on the remote control until every button has been pressed and released at least once!
Step 3- If your remote has slide switches, you must move the switch to each position then repeat the button pushing in Step 2.
(When you're done, be sure to put the slide switch in the correct position to operate the unit the remote came with!)
Step 4- Put the batteries back into the remote, being very careful to install them correctly.
New batteries should be used if you're not sure about the old ones.

Try it again. If the problem is still there then the remote is bad.
Since this is a new TV you should use your warranty to replace any bad parts.

Tv does not respond to remote commands


You need to isolate the problem.
1) Unplug the TV for a few seconds and then plug it back in.
2) Operate the TV with the buttons on the TV. (Channels etc) I presumed you have scanned in the channels.
If no problem found then do this for the remote.
Step 1- Pull the batteries out of the remote and leave them out until Step 4.
Step 2- Press and release each and every button one at a time on the remote control until every button has been pressed and released at least once!
Step 3- If your remote has slide switches, you must move the switch to each position then repeat the button pushing in Step 2.
(When you're done, be sure to put the slide switch in the correct position to operate the unit the remote came with!)
Step 4- Put the batteries back into the remote, being very careful to install them correctly.
New batteries should be used if you're not sure about the old ones.

Now try the remote to see if it works. If it fails you will need a new remote.
