47lm5800 locking up

If only one button does not work at all or all do not work the unit may have a lock out feature that would be explained in the owners manual.

Hi Keith,


First of all, thank you for posting your question here at Fixya.

My first advice is to confirm if the remote control is not the issue here and ensure that the fault came from the TV itself. Point directly your remote control's infrared emitter(Sensor) to your cellphone camera and then press any button key at the remote control, you will be able to see the flash of an infrared through your camera if the remote control is working fine. Watch the video below to have an idea how you gonna do this.



If you've confirmed that the remote control is not faulty, this is an indication that the problem is on the infrared receiver inside the TV. I would advice you to clean the TV's front panel infrared lens using a soft cloth, keep away all obstruction from the IR receiver, turn of the bright light in the room and check if the symptoms still persist. If yes, then the IR receiver inside the TV is already faulty and needs to replaced with a new one.

Hello,

there are basically two reasons why this is happening; 1. it's either the TV's timer is on accidentally or 2. your TV is having a power problem.

Check the timer settings on your TV and make sure it's set to off.

But if you've confirmed that problem is not from the timer, then it means the TV is having a power problem. The power board of the TV is dying gradually due to defectiveness of some of its component.

Have the timer checked first, then give me a feed back, so that I can give you some diagnoses on the power issue.

Yours sincerely.

This is the Digital/Analogue input choice. The TV has probably locked up due to a signal failure, try switching the TV off from the mains electical plug, leaving it for 30 seconds, then plug the TV back into the mains socket & try switching it back on.

My JVC 35 " AV 35750 toggled on/off non-stop too.

Fix for me: Unplug TV. Trace cables from on/off switch to main circuit board. I unplugged the cable at that point to eliminate the the on/off button and remote control sensor. Applied power to the TV and my TV stopped cycling on/off so I figured the problem was probably not on the main circuit board but with the push button/ remote control sensor board. I again removed power from the TV and plugged the cable back in to the main circuit board. I then applied power back to my TV to verify my symptom, but when I did this, the TV worked fine again.

Many times resetting circuit board connectors will clear electrical problems.

Hello, follow this link to download the manual and the codes for your remotes:
http://www.ofausa.com/remote.php?type=URC6131
just right click and save as on the download links.

if this does not work you can try the search method,
you do this by either holding down the device button eg: TV or if you have one the "magic" button for three seconds, a light should then flash twice to say you have done this correctly.
then press the keys 991 then the power button.
you must now press the channel up key (ch+) possibly upto 150 times while the remote cycles through every code.
Once your tv or device switches off stop pressing the ch+ key and press the power button to make sure it switches back on,
(if you press ch+ too many times you can go back by pressing ch-)
When complete press the magic or device key again to save the settings (light should flash twice to confirm)

Many thanks
Mark
