Okay; the tv was working bt it had a thin vertical line on the left side. i attempted to find out which board was going bad. Ok, i unplugged them and now no picture. I unplugged the x board and replugged it. that when it clicked a few times and now no picture. If i unplug the x board; it will make sound and it appears that he picture will come in, but it never does. if the x board is plugged up; no sound no attempted picture. wen the x board isnt plugged up; and i power it on; i can still see the thin vertical line. do i need to replace the x board and what can cause the very thin vertical line???

Re: Samsung: PN50C450B1DXZA
It can either be a faulty board or burned chip on panel ribbon cable.
It will not be repairable if it`s a chip/ribbon failure.
A thin vertical line would make me take a closer look at the supporting board. (bottom of tv panel)
A 1.5" black vertical bar would be whole chip failure. (parts tv)
If you keep doing what you are doing it won`t even be a parts tv.Last edited by cadiman; 04-30-2012, 06:48 PM. -

Re: Samsung: PN50C450B1DXZA
If you had a coloured line, the plasma panel (PDP) was likely bad. It's more than possible it went from slightly bad to completely shorted, taking out the whole picture in the process.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

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...
