Question about Televison & Video
I've had the TV for around 4 weeks. I tuned in all the stations, although it is mostly used for my pc via a VGA cable. Turned it on today and was greeted with a black screen and the message 'do not power off'. It now continuously tries to scan, but every time it reaches 64% it starts scanning again. Both the remote and buttons on the TV are unresponsive. Any ideas of what the problem could be?
Try unplugging the aerial while the tv is off, then turning it on.
Plug the aerial back in when the tv is on, then re-tune.
Im currently in the process of doing this myself hope it works...

Change the main board if you have good picture and sound. If you don't have picture and sound, the inverter will also need to be change.

If the screen is black and you have sound then lightly press and shine a strong flashlight against the screen. If you see an image around the edge of the flashlight, an image is being 'displayed'. The problem is probably in the Inverter/CCFT or the power going to the Inverter.

i had the same problem with a 32 inch and i kept "clicking" the channel changer on the remote to force the tv to go to another channel (that had previously been selected during the initial auto scan) --- still trying to figure out why the tv locks onto the scanning for channel

Sounds like you're having a problem with your main board assembly. The main board is what processes all your audio/video signals. So if it's not scanning DTV you've probably got a bad card. Call LG's customer support line at 1-800-243-0000 and have them schedule you a service call. Request a DMST if there's one available in your area as they actually work for the factory. Otherwise you may get an ASC(authorized service center) which can be less than reliable at times when it comes to customer support and satisfaction.
Remember to have your proof of purchase handy as well as the full model and serial number. And by model number, I don't just mean 42LG30. On the side or back of the unit there will be a manufacturer's code. The first part is indeed the model#. However, it will appear something along these lines:
42LG30-UA.AUSRMJR or something similar to that.
Have that ready definately. Any tech worth their salt will call you a few days beforehand to try to get that data so they can order boards before coming out there, saving them, and you, an extra trip when they have to come and order boards. Without that extended manufacturer's code, LG techs have a hard time with a lot of models trying to order parts as different revision codes and such use slightly different circuit boards.

Please count Sony KDL-46V3000 standby light blinks as there would be interval of 3 seconds between blinks. Let me know how many times light blinks as its an error code.
