SOURCE: i have a 47" flat

You can try digital audio headphones. Just connect the optical audio out of your tv to the base of the wireless headphones and turn on your headphones. Only problem is that these things are a bit expensive and cost 230$ , but the advantage is it is compatible with any device that has an optical out. Just plug and play

Alternatively you can hook up a receiver with optical in , to the tv's optical out and then connect your headphones to the receiver. This is an inexpensive option but the audio quality would not be that great as its analog audio.

SOURCE: 37" LG flat screen is

With the onset of more and more TVs being hooked up to cable, TV manufacturers didn't need to make the tuners as sensitive because the signal from the Cable Co. was much stronger than the over the air signal. If the other TVs are older they may be just sensitive enough to lock onto the channel signals. You could ask your cable provider to check your available signal in the house to see if there is the proper amount of signal. Some channels can inherently be stronger and when "block converted" (put where the cable company wants the channels) all come thru but some are a bit clearer.

Lines shooting across screen.

Only way to know is replace all possible boards one at a time---900 is a bit low for a display panel which can cause lines as the worst case situation---

We have a 47 "

Try tapping the TV. If the problem comes and goes as you tap. There may be a dry solder joint on the circuit board or a loose connection.
If the above happens then explain this to the an electronic technician or someone who has some knowledge in repairing TVs.
You can attempt in re-connecting wires in the system but it can be dangerous as there are high voltages which can cause electric shock even if the system is off.

All the best

Remote won't work. Tried new batteries, reprogramming, etc. Universal Remote doesn't work either. LG #42PC5DC

Hi,
To confirmed if the remote control is working fine, aim the remote control sensor(IR emitter) directly to your cellphone camera. While pressing any button key on the remote control, you can see the flash of an infrared emitted by the remote control if it is working fine.


If you've confirmed that the remote control emitted an infrared but still the tv won't communicate with it, this is an indication of faulty IR sensor board of the TV. Check if there's an obstruction from the IR receiver in front. Keep away all of it, clean the plastic window of the IR receiver with soft clean cloth.
If the symptoms still persist, you have to replace the IR sensor board. Check the actual part no. of the board before ordering.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Where is the ir on the jvc LT-47x899

Usually the IR receiver is located on the same board as the controls on the front of the TV or the same as the LED lights. If you suspect the IR sensor as being bad here are the part number for the control and LED pcbs. Please take a moment to rate my answer. Thanks..

CONTROL PCB: SFL-7224A-M2

LED PCB: SFL-8733A-M2

My LG 42LB5D TV can't be turn off unless I unplug

It sounds like you have faulty logic in your main board. The remote issue could also be related because the main board controls the processing from the IR sensor which is more likely because IR sensors rarely fail.

Replace the main board to fix the TV.

LG 47LC7DF LCD TV Remote Sensor not working

IR senor may not be bad. Try using a different remote (universal) and program to TV. If universal remote works and your doesn't, you may need to purchase a remote instead of IR board. If you confirmed that the IR board is bad then replacing the IR board will fix the remote issue. IR board is an easy fix. Just open the back cover out and it's located right in the middle toward the bottom of the TV.
