Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
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.

I have a LG 50ga6400 google tv. When I turn the tv on, the LG emblem shows up then the screen goes black with sound. You can see the screen with a flash light.


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.

Some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

How do I unlock my Dacor cooktop


When your Dacor cooktop is locked, there will be a red light lit above the Dacor emblem located under your cooktop controls.

If you see this light, pressing the Dacor emblem for three seconds will turn it off and unlock your range. Pressing it again for three seconds will again lock your range and turn the light back on.

Another fun thing about that Dacor emblem is that if one or more of your elements are lit, tapping it twice in quick succession will turn off all elements.
