Your video and audio (sound) signals are generated on the main board. However, for those circuits to work properly, they have to have clean and accurate power from the power supply board. The power supply boards are notorious for bad capacitors. Has your power supply been recapped? Do you see any bulging tops of any of the capacitors? If you are not familiar with capacitors, just google bulging capacitors. There are plenty of pictures on the web to show you what they look like. It is possible that the main you have has a problem. I assume you order the same exact part #?

SOURCE: I have a broken Samsung UN60FH6003FXZA . Has sound but no picture. Did flashlight test & can see menu options. Suspected the power board/ LED driver is bad. Replaced board and the problem continues
It appears to be the backlight problem and it is common with almost all the brands. Some of the LEDs in the backlight array fail or burn and cause this problem. Replacing these LEDs solves the problem, but it is a delicate and risky job.The panel has to be opened for this and only an experience technician must do it.
Here in India we do it regularly.

Testimonial: "than you"
SOURCE: Samsung UN50H6350AF LED TV. No picture. I do get backlights and sound. (See pic) I tried replacing the main board and the T-con board and there was no change. Any suggestions? Try power supply board?
You have wasted enough money guessing bite the bullet and replace the TV. I have done this same thing and regret it to this day, should have just junked it.
