Will main board from 42lcd insignia work in 47lcd insignia?

I have a main board in insignia 47lcd that i suspect is messing up plays for 10min and picture goes out, all power supply good. Still have sound. Also suspect Tcon, i am getting error red light 7 flashes upon turning tv off. Swapped in a main board 715t2830-2-2 from a 42lcd insignia same year. The boards appear one hundred percent the same and have same number but another serial number tag carries two different numbers. Now i get blue powerlight but tv or backlight never turns on and upon turning off i get 15 flashes. Should this board have swapped equally , i feel like it is bad too. What do you think.

ONLY if the panels are the same series but different size, OR if the TV has an easily accessible service menu allowing panel settings to be changed. The seller may be able to tell you.

Panel number is on the back of the LCD panel e.g. LCW420AA8A.

Where does the tcon get power from . mine has a set of wires in a plug going to it from the main board and a ribbon cable with about 4 wires coming from the inverter board. Whats the connection between invereter and tcon board carrying. I just ran the tv for about 15 minutes playing excellent then screen looks like it melted kind of stretched concave on the sides and went off. i got sound and power but no picture and no menu screens. What do you think.

Usually power comes from LVDS connection... Can you get us a picture, or better, a video of the problem?

Received new tcon board today and got it in the tv. I have about 5 hours of use and its working perfect. The tcon was the problem. I have one last question when i turn the tv off the blue power on indicator is still flashing red 5 times upon shut down like it has an error code. Could the main board still have a fault in its memory. Does anyone know a factory reset for this television as it has no option in the menu screens. Maybe this would fix the flashing. Thanks
