I sent LG Support team and email and got a response.
Received Date : 12/17/2010 19:18 41 The type of inquiry : Others Product/Model No. : Conventional/Flat TV/32LD450
I was unable to find the Firmware sources for this set at http://opensource.lge.com. There are the sources for 32LD350 and 32LD420 and 42LD450 but not 32LD450. Based on the In-start menu the model is a GLOBAL-PLAT2 and the Chip Type Saturn 7, the same as 42LD450 and LE5300. Can you make public the sources of this model as GPL License requires. And if posible please respond to this email to now the it was at least read.
A few days later I received this response:
——Reply to Your Inquiry——-
Dear Harry, I apologize for any delay and inconvenience you may have experienced. I can assure you, I will do what I can to assist.
The 42 and 32LD450 are identical except for screen size. You can consider the 32LD450 and the 42LD450 license and source code identical.
Other than adjusting your antenna, maybe raising it higher, there isn’t much else we can do. If the issue persists, then it may require service.
If you have other questions or concerns, please do not hesitate to contact us again either via email, or by calling our customer service division at 800-243-0000 at your convenience.
