Sounds (no pun) like a control issue in the set--have you disconnected it and a box if used from power for a length of time to see if a reboot might help or not?

call 877-543-8325 this is an LG Executive call center and they will fix this for free. I have a 50" plasma I bought january 2006 which is out of warranty by 5 months. They faxed me and the LG repair shop a 30 day warranty for my tv to cover the repair. Just tell them you heard a pop and in my case the picture is distorted. All they need is the model number and serial number and they should take care of it. No arguing needed.

SOURCE: my lcd tv makes a humming noise

Try removing all cables going to the TV except the power cord. Power on the TV and press mute. If you have any unwanted noise, then you have a defective TV and since it is new, you should get an exchange. If there is no noise with the A/V cables removed, then you might have hooked the source (cable box/DVD Player) into the wrong inputs of the TV.

SOURCE: LG 50PX4DR plasma tv

I had the same exact problem as posted above. My 50" LG plasma was out of warranty for 1 year! I called the LG executive call center, and they were very helpful. They offered to pay for the parts and labor. They recommended a few local repair shops, and they set everything up for me. The tech came out within 4 days with one part. The tech had to come out one more time the following week, since more parts were needed for the repair. The Y sustain board, along with 2 adjacent parts that are required to be replaced as a set, and the power supply had to be replaced (parts alone cost just over $900). TV is like new again; I'm very happy with how LG handled it, and made what could have been a bad experience a good one.

No sound on an lg 37lc7d tv?


Your main pcb could still have gotten damaged due to the defective caps. The reason you still have audio through the optical is because it is a digital signal only. It is not running through the audio amplifier on the main board. I would suspect either the main pcb or the speakers them self.

I have a Lg 42" lcd tv (42LG3000) TV is wall


White screen with good audio. before buying pcbs & such. try my repair method.. you need to get the lcd unit off the facia & then remove the front lcd metal frame. at the top of the screen you have 2 thin pcbs - chances are that the ribbon cable got at least one track unbonded. first off put some double sided tape under the pcbs to stick then to the frame - that'll take the bend out of those pcbs !! next put cellotape over the ribbon cables. i then cut 6 pieces of sponge 15mm thick & wide as the ribbon cable & glue to the tape on the ribbon at what would be the top edge of the screen (covering the point where ribbon meets pcb).. put the metal frame on top edge first to keep the sponge straight !! put it back together & fire it up. if it still aint working you may need a tcon pcb (little square one at the top). this fixed my 42lg3000 but can work on others with same fault !!

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
No technician can do more than this, he/she can do anything except.
