Question about Samsung Televison & Video
I have the Samsung UN32H5203AF US02 TV. It suddenly went black. I checked the backlight and there isn't any. I checked the screen using the flashlight and you can see the menu, etc. Sound is good! Called an online part supplier, they sold me the power board. Changed it, but did not resolve the issue. Another tech told me that it is the LED driver or LCD inverter. I have the service manual, but it does not reference either parts.
In most of the case, the problem is the LED back lights strips, it was the most case we encountered.
To check it, un-plug the cable between the power supply & the main board, apply the AC power to it, if the back lights came on, replace the main board, if not, mostly the problem is the back lights LED strips.

I have a television that did this. The picture went out but it continued to have sound. It was the projector bulb. I ordered from a dealer on ebay, very resonably priced. It came with instructions on how to install it and was a very easy fix.

SOURCE: Seiki led tv has sound but no picture. The picture can be seen with flashlight. We tried resetting default on menu with tech support, still no picture. Has no backlight. Which part should we replace?
You are correct, this is a backlight issue! The screen inverter is usually built into a circuit board, if you want to attempt this yourself you will need to access the circuit boards to see which one you need to replace! If you open up the TV and post a picture we will be able to point you in the right direction!

Fault with its main 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. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
