Hi All, I am new here and looking for some help. I have a Samsung 55 inch LED TV that just clicks the relays on the power board when powering on, with no picture. I have done some reading here and tried a few trouble shooting items. The TV model number is UN55B6000VFXZA version BN02. The power board is BN44-00271A, the main board is BN94-02657X and the T-Con board I am not sure of the part number but there was a pink dot by V546H1. I checked voltage at the power board and they seem to be okay. When I disconnect the main board the LED backlights come on with no clicking. When I tried to check voltages coming out the power board to the main board, I was having trouble finding voltages. I'm not sure if I was doing something wrong or not. Connecting or disconnecting the T-Con cable doesn't seem to have any affect. I hope that I have provided enough information for any of you to help me identify the cause and how to correct. Thanks, J

Re: Samsung clicking and no picture
I know someone having a similar issue. Does this click without the hdmi ports disconnected? Something may be loading down the power board. Post pic tooThe strong-minded rise to the challenge of their goals,the weak-minded BECOME HATERS

Re: Samsung clicking and no picture
Hi All, Thanks for the help. The clicking happens without anything connected to the HDMI ports. I swapped in a main board BN94-02657M from a working UN40B6000VFXZA which is the same P/N just with a final digit of M rather than X and the 55" set turned on fine. I have a board on order and should be able to get the 55" set fixed when the board arrives.Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic... -
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.... -

Hi all!
I've recently run into an issue with my Samsung UN55H8000AF LED TV displaying no image. I've done quite a bit of research in terms of what could be wrong with it. Below are the steps I've taken prior to reaching out here for some assistance:
1. I've tried replacing the T-Con board (BN95-01594A), twice and have still experienced the same issue with all the boards I've tested with.
2. I've tried to remove one side of the ribbon cable that goes from the T-Con board to the panel and still not getting any image on left or right side.
3. I've checked voltages...
