When you turn on the tv the green light comes on blinks a few times then turns on. there is no picture no sound


Not so sure but looks like is seted up on HDMI input. So when you start it is trying to find and decode the signal but probably there isn't one. So try to switch it on another imput like TV or AV. Is there a death screen also, like no light no anything?

Buzzing sound


Hello, This is a problem with the switching transformer or the ballast used to fire the backlight. You will have to replace the ballast and or the switching transformer soon. In order to replace these items, I would suggest taking it to a qualified TV technician for servicing. I hope this helps, Thank you, Shuttle83 http://www.electron-age-technologies-llc.com

Here's a link to the service manual for a slightly larger LG LCD TV. Perhaps it may be of some help? The troubleshooting section appears to be the same for many models of LG TVs...

Delayed signal to my lcd from the cable box.


It is not that rare to have a few secound delay but it sounds like yours has some componates that have gotten alittle hot at times and now take longer to come up if you haven't put a surge protector on it I would do so . To day with all the brownouts and power spike the newer units can not handle this couse of the componate being a lot smaller and as we put more and more ecectronic in our homes we create are own power drops the only way to help this in most homes is to use surge protectors.
