UN55NU7095 motherboard

[Thomas Prutzmann]

I recently changed the motherboard on my tv from a UN50NU7095, they are almost the same tv, so I thought it would work, well, I changed it (they looked the same) and it turned on, but the image looks distorted and the colors are wrong, so I need help to set it up or configure the motherboard

Hi and welcome, sadly looks the same if usually not the same.

I know even One Connect boxes only work with specific models.

Why did you change the motherboard?

[Thomas Prutzmann]

I changed it because one tv had a dead motherboard and the other a broken screen, so I thought it might work if I mixed them

Hi @Thomas Prutzmann    Welcome to the uk/Ireland/ European communities   I do not think swapping over was advisable, Motherboards can be model specific.  You would be contact Samsung Support, from the model number asssume you are based in the US.  https://www.samsung.com/us/support/contact/

US community is here should you need it. https://us.community.samsung.com/t5/Samsung-Community/ct-p/us?page=1&tab=recent_topics

If the part numbers of both boards match, then everything is likely fine, and the issue might be related to the incorrect display type setting. Keep in mind that 55-inch and 50-inch displays are produced by different companies. For example, Samsung has never manufactured its own 50-inch screens and currently only produces OLED panels for TVs.

To resolve the issue, access the service menu and set the correct display type in the settings. You can find detailed instructions on how to do this here. If you need help entering the service menu, follow the guide here.

Ideally, check the sticker on the display to determine the correct type. Alternatively, go through the menu options one by one. There will be a few 55-inch display options—select the one that fits best.
