Well if the speaker are not blown the audio IC on the main pcb is defective. If the TV is still under warranty get it service if not you need to replace than main board in the TV.

Hi i need urgent help for some reason when i plug my headphones in my Bush lcd, the headphones work fine but the sound still comes out of the tv


sounds like the wrong plug end just because it works doesn't mean its right plug end. as usually the bulb on the tip of the plug closes a switch to turn tv speakers off this obviously isnt happening

Internal speakers won't turn off when external audio is connected


Normally , you would expect the TV sound to stop when headphones are plugged in. Obviously not in this case. If you have a set of headphones, try them and see if the TV still has speakers on. If it does, then there may be a setting on the setup of the TV to get headphones to work. If the TV speakers stop, then I would think that the Logitech are not compatible with the TV. The only other thing would be is to get into the TV and disconnect the TV,s own speakers. If the wires are soldered on and not terminal connected, carefully cut 1 of the wires off near the speaker. If 1 wire is cut, the speaker wont work. Make sure both the TV and the additional speakers (If they have their own power supply) you are using are unplugged from the power before you go doing this...!

Sound through only one speaker


Check the other speaker which do not work. In most cases, the speaker is found faulty. If so, replace it with a similar one.

Speakers stopped working suddenly? how can i fix iy?


Hello
A sudden stop of sound output while the set works denotes either its speaker or audio output IC damaged. Check the speaker first by using a multimeter for its voic coil continuity. If speaker is OK, the fault is surely with the audio output IC. It should be replaced with same type and number. It is a semi-skilled work, you have to open your tV, locate the audio output section. You must have knoledge in electronics to do this work. OK.

I have a panasonic TX-37LZD70 lcd tv the sound has suddenly gone -tried all the obvious ie mute and volume any suggestions


Have you tried connecting some external speakers to the audio out ports? Most modern TVs at minimum should have analog RCA outputs. See if you can connect external speakers to verify functionality of the sound processor. If you get sound, that probably means one of the mosfets or speakers have failed. Either way, a DIY repair would be next to impossible. Your best bet would be to contact a repair shop and see if this is a common problem with your TV. Allthough inconvenient, you may find it acceptable to use the external speakers if they work. Good luck.
