TV Samsung.UN60H6350AFXZA No picture. Has sound. No backlights. Can see picture with flashlight test.

The Picture Off mode could be enabled if the picture is visible for a while. To check if this is the case, press any button on the remote other than power or volume. If it is, press Menu. Enter the Picture sub-menu and select Picture Off. Disable the feature. This feature is described in the E-manual for the 6350 series TVs here: https://www.samsung.com/us/support/owners/product/2014-led-tv-h6350-series . See http://www.manualsdir.com/manuals/421041/samsung-un32h5500afxza-un32h6350afxza-un50h6400afxza-un48h6400afxza-un65h7150afxza-un60h6350afxza-un65h6400afxza-un48h6350afxza-un40h5500afxza-un60h7150afxza-un46h7150afxza-un50h5500afxza-un75h7150afxza-un60h7100afxza-un55h6350afxza-un40h6350afxza-un55h63.html?page=163 for just the page on the picture off mode. If the picture is dim at times, check if the eco solution mode is enabled (System > Energy Savings).

If the screen is always dark, then the back light is not working. This can be caused by the failure of the LED back lights or the inverter that powers the backlighting. If you see a faint image when you shine a flashlight at the TV, this could the problem. The inverter usually fails before the LEDs. Replacing the inverter requires opening the TV and could have a shock risk. Replacing the backlighting requires separating the LCD panel from the bezel and getting between the layers at the edge of the panel.

I hope this helps.

Why would you replace the power board for a burnt out backlight problem??

The term backlight means any light that shines through the LCD. The unit that you have uses LED back lights and the strips are available at https://www.shopjimmy.com/samsung/un39fh5000fxza

graphical card issue or lcd needs replacement

The Audio and Video are two separate components and operate independently of each other. Therefore: The Video portion requires technical repair by a technician with the proper test equipment.

Try the flashlight test to see if its a backlight or main board- timing board issue

Do flashlight test - if you can see image you need t con board. If no images seen, inverter board. TV Parts Universal TV Stands DLP Chips ShopJimmy

Hi Rick,
It appears to be a case of backlight failure. since you have replaced all the boards, inverter is ruled out. Some of the LEDs in the backlight array may have gone bad. Fault is repairable, but needs care and experience of opening and repairing the LED panel. Good luck.

Here's the test. With the TV on shine a flashlight on the screen. If you can see a dim picture the backlight circuits are bad. If you cannot see a picture the T-Con board is bad. You can get parts from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

If you see a picture with the flashlight you can rule out the T-Con board. It's working. So the led driver board is the problem. TV Parts Universal TV Stands DLP Chips ShopJimmy Go here for replacement parts.
