SOURCE: My Samsung LED Series 6 TV does not have picture but does have sound. Thanks.

It could be your mainboard. How long did you have the TV?

SOURCE: I have a 55" Samsung smart tv model # UN55ES6500. Half of my tv is very dark and can barely be seen, the othet half is fine. Does anyone know what part I would need to fix this issue?

It seems like back light problem. If this set is LED back-lighted type, the LED blocks inside should be troubleshooted. If you wish how to check the LED backlight blocks, visit the site linked here. Pull up older posts. One among it have details about how to check it.

Dave, If you have an in home extended warranty already paid for, it will not hurt to have it checked out. The repairman may know exactly what the problem was and change/fix TV if there is a known part that can be intermittent.

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. http://electronicshelponline.blogspot.com/ To 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. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board..

Our samsung smart tv screen goes dark at nightfall. We have to open the blinds to let light in to get the screen normal again. Is there some kind of setting I can set to stop this from happening?


It is there. Designed to have a brighter picture during the day and dim it in the evening. Have different names for the feature.

Check your manual out for it.

How can I fix My Samsung 28" smart tv it is just frozen on the "smart tv" screen after powering up. I have tried holding exit - unplugging but still it is just stuck on the and won't do anything


I work fixing TVs, and am a Samsung authorized servicer. Outside of doing the best thing, which would be to take it to a repair shop, it needs a Main board. The power supply is fine or it wouldn't make any picture, and cleaning something won't fix it.
