Question about LG 42LG50 42 in. LCD HDTV
Usually when the OSD will not come up, you are looking at a problem with the video boards. Is the power button flashing or showing a different color, or does it look normal in the On position. If it's flashing, then the problem lies with the mainboard not powering up properly. It might not hurt to try a power drain at least:
1. Unplug the product's power cable so that the device is not grounded to the house. Do not simply turn off the power-bar if one is in use.
2. Press and hold in the products power button for 1 minute to release the retained electricity from the capacitors and circuit board. 3. Plug the product back into the wall outlet rather than a power-bar to rule it out of contributing to the problem and turn the device back on.
If this doesn't work, the TV will likely require service.
