Question about LG 37LG30 37 in. LCD HDTV
Gives blue light, but screen stays black and no sound. Had HDMI plugged into laptop and could select it through input. Hit input now and see light flash but menu wont display. Maybe stuck in PC mode?
Sounds like the problem could be in the power supply of the TV. Have a technican check for defective capacitors if you're not equipped to do the job yourself.

Try restoring to factory settings for everything(I believe there is an option there in one of the options menus). Double check to then see if it's set to set by program.
If that fails to work you may be having a bad main board issue if it is the TV. Make sure it isn't your cablebox being stupid, though.

SOURCE: LG 37LG30 HDMI no sound problem
This is more probably a software fault within the TV. They need instructions for HDMI inputs & a no sound is a related fault. I would get in touch with your dealer to arrange the TV to be updated to cure this problem. Hope this helps.

I have the 1525 and you have to do extra steps each time you want the HDMI to be recognized by the Bravia - too bad it is not automatic as it is with some. Anyway what you have to do is have the HDMI cable connected from laptop to TV then go to your desktop - right click on an open area (away from icons), a menu will appear, let the cursor hover over Graphics Options - you'll then see Output To...then you'll see Intel Dual Display Clone...hover over that and you'll then see Notebook + Digital Television...left click on that and you should see your desktop on the TV in a few seconds. If it does not work the first time...get your movie or whatever you want to show up and ready and go thru these steps again...stupidly complicated aye? when it should automatically detect and show...are other TVs like this?
