Fault at its main digital board. Short circuited component/s at it

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

TV Changing Channels on It's Own
Are you changing channels with the remote? Try taking the battery out of the remote, its buttons might just be getting stuck? If, when changing the channel by hand, it persists, then it is an electrical problem, and you should contact LG to see about getting your unit replaced.

321C7D black screen
Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should be troubles hooted. Contact any service technician. The circuit will differ with models and versions.
Type in the brand name of your device, in the search box [at the top right] of the display window and the Search will start at once as you type in, and will show you all the related posts. It will make surf easy.

MY 32LC7D tv when shut off takes its time to turn back on but now when i tried to turn it back on the green light constantly blinks and no matter if i unplug it the green light automatically comes bac
Televisions now are equipped with a diagnostic circuit that send a low voltage , low frequency signal throughout your set when you turn it on. This is to detect any problems with the circuitry and protect the good circuits.. It started out with a component that wasn't working properly but finally returned the signal. With continued use the component finally burnt out and now your set is going into standby mode. The blinking Green light is a code X amounts = a certain problem. Look up the make and model on the internet and it will give what 2 blinks, three blinks, etc means.. It could be anywhere in the set but the blinks will pin point to the board more than likely. Probably in your power board and if you are lucky it is just capacitors which you can replace yourself if you are a DIY 'er. Check out their web site and find out what your problem is first. Good luck!
