I have a Samsung UN55B6000VFXZA BN02 that tries to power on but the relays just click with no video or backlight. When I disconnect the power board from the main board, the backlight comes on. I have checked the power board (BN44-00271A) fuses and they seem fine. I also checked the 30 output pins for the voltages and grounds printed on the board all seems acceptable. I don't have a repair manual for it yet, so I don't know the procedure to check the H-sync, Inv err or BL On/off properly. Any help or suggestions to identify the failure and how to fix would be greatly appreciated. The main board is BN94-02657X. I'm having trouble finding a P/N on the T-con board, but there is a pink dot in a box by a V546H1 marking.

Re: Samsung UN55B6000VFXZA BN02 just clicks, no power on, no video
I had one of these sets. It had two cracked solder joints on the backside. I don't remember what the
Q# was. It was next to a heat sink. I resoldered it and set worked fine. -
Re: Samsung UN55B6000VFXZA BN02 just clicks, no power on, no video
Thanks for the help Ltank. I have a UN40B6000VFXZA that uses the same main board with an M final digit rather than the X on the 55's board. I swapped the main board and the 55" set started up fine. I have ordered a main board and should be able to get the 55" set going as soon as the board arrives.Comment

Hi There,
This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.
After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

I hope this is the right forum to post in despite not technically being a repair, but still a question of swapping boards.
I thought I'd explore the possibility to upgrade an existing working Samsung ue55nu7096u with the logic board (and power board if needed) of a newer model (ue55ru7105k) of the same size and appearance (and resolution). The reason being I'd like the extra inputs of that board including component in, an extra HDMI port and bluetooth. Its panel is broken so I have no use for the board otherwise.
The models launched in 2018 and 2019 respectively.... -
