Green light flashes 6 times then goes to standby no picture or sound


This happened to me with a TOSHIBA Regza 42" flat panel. I spent $180 dollars to have the TV taken off the wall, transported to the authorized TV repair shop to have them tell me it only required a firmware update!

I suggest you go to the LG support page, plug in your model # and instructions on updating firmware to that TV.

Good luck!

I have a 42in LCD with USB. But for some reason we cannot get anything in a hard drive to work via USB.


Are you talking about LG 42LC2D model/? There is no USB port for this model LG 42LC2D, some TV uses the USB prot for firmware update and servicing only, be real careful what you plug into it or you will have a dead TV!

Invalid format error with P1600 blu-ray and LG LCD TV 42"


It may be a firmware issue if hdmi works with other items such as playstation.
If no hdmi the main Pcb hdmi ports are bad and the main Pcb would have to be replaced.

Consumers cannot upgrade the firmware so a shop would be the only option.

I have an 47LG LH30 LCD television, when watching shows that are broadcasted in HDTV, there is a delay between the sound and picture. How do I fix this problem?


You need to update to the latest firmware. This was an inherent problem in many LG LCD TVs released around the same time as yours but can be easily resolved by installing the latest firmware. You can call LG to have them send it to you on a USB flash drive or you can go to their website and download it along with the instructions. You will need a USB flash drive an plug it into your TV to intstall the firmware.
