Question about LG 42PX3DCV 42 in. Plasma EDTV

LG Plasma TV has speakers fizzing in short bursts, cant hear any audio

I just bought an LG Plasma, it worked for about 20 mts. I then shut it down. After 2 hours when I opened it, the speakers were making loud fizz noises in short bursts, the video was fine and couldnt hear any audio except for the fizzes in short bursts. Have the speakers been damaged?
The noise is coming when I select AV In or Component In or anything as input. The noise comes even when nothing is connected to the TV and it is far away from any other cord or appliance.

Yes I believe you have a hardware failure in your audio amp IC. In some cases, a speaker will cause all the audio to distort, but its very rare for a speaker to cause this issue. If you just got it, you can return for a quick resolution, or contact a local repair center for a new main board replacement.

Lg tv ticking


There is some shorted component/s in the circuit board. The short circuit protection circuit detects this short, and shuts down your TV again and again. That is why you hear these 'tick' sounds repeatedly. Contact any experienced service technician to get your TV repaired. The work is skilled one, which need sound knowledge in electronics, and work experience.

No sound,but good pic.everything else works fine.(toshiba 57hx94)


hello,

• Check the antenna/cable connections (see Chapter 2).

• The station may have broadcast difficulties. Try another channel.

• The sound may be muted. Press VOLUME.

• If you hear no sound, try setting the MTS feature to STEREO mode (page 81).

• Make sure the SPEAKERS function in the AUDIO SETUP menu is set correctly (page 83).

• If you are not receiving a second audio program from a known SAP source, make sure the MTS feature is

set to SAP mode (page 81).

• If you hear audio that seems "incorrect" for the program you are watching (such as music or a foreign

language), the SAP mode may be on. Set the MTS feature to STEREO mode (page 81).

• When using an external audio amplifier, if you connect the amplifier to the VAR. AUDIO OUT jacks, the
volume of the TV and amplifier must be set above 0 or you will not hear any sound (page 20).

I cant get the lg lhb977 to work with my cable box. what do i need to set up to hear regular tv not just blue ray and dvds


All i did was run regular red and white audio cords rom my cable boxs audio output to the lg lhb977's regular red and white audio input. and press function enough times on the front of the system till it gets to "AUX" and then it worked for me. As long as you go to ur actual tv options screen and try to set ur speakers to "external speakers" rather than "tv speakers". hope it works
