Re: Samsung UN55KU6300FXZA
How many blinks? which are the readings on the leds outputs with main board disconnected? if you pull out the Fail count contact from the psb>mb cable with the help of a mini flat screwdriver and you try boot up tv what happens? in an other manner, all things connected, try pressing exit key on RC for at least 15sec., last try, try enter service menu..Last edited by Davi.p; 09-12-2022, 12:04 AM.Comment

Re: Samsung UN55KU6300FXZA
My main board is BN94-10651G. Power board is good. I'm having trouble finding this exact one. Do other models work? I don't care if I lose a port or something.Comment

Re: Samsung UN55KU6300FXZA
I wouldn't be surprised if the first or second worked for you, you could contact them and ask if they know: https://www.shopjimmy.com/search.php...UN40KU6290FXZALast edited by nomoresonys; 09-13-2022, 03:57 PM.Comment

Re: Samsung UN55KU6300FXZA
I did it with an un55h6350, had to modify one connector, lengthen a speaker wire and cut out a bit of the back cover, didn't have to change anything in service menu.Comment

Re: Samsung UN55KU6300FXZA
This can be done when T-CON is not built into the motherboard (when T-CON is installed at the bottom or soldered to the bar of the matrix itself).
This model has a separate un55h6350 T-CON (not built into the motherboard), here you can put any motherboard from this series (chassis).Attached FilesLast edited by lotas; 09-14-2022, 06:58 AM.Comment

Re: Samsung UN55KU6300FXZA
ok, thanks for the explanation Lotas, so it doesn't look like that board will work in this case, probably best to cancel the order from shop jimmy, I did see a board for about 50 bucks for the 55 inch.Last edited by nomoresonys; 09-14-2022, 07:22 AM.Comment

Re: Samsung UN55KU6300FXZA
Symptoms EEPROM replacement MAY fix:
- On screen display is stuck on logo screen
- TV will not power on with remote or buttons (LED indicator remains same color)
- TV will not turn on after being off for 30+ minutes
- TV shuts off by itself during channel scan or when switching inputs
- TV turns on and is stuck in color test pattern mode forever
- TV turns on but there is no backlight (LED indicator shows TV is on but there is no image)Comment

Re: Samsung UN55KU6300FXZA
may be able to test eeprom by heating it with a hairdryer or cooling with freeze spray or inverted can of duster spray, then turn tv on and see if there's any change, don't wait after heating or cooling, turn it on right after so its still hot or cold.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.... -

Hey everyone,
This power supply board is hard to find but there are repair kits available. This board had a blown fuse, FP801S, blown PFC MOSFET, QP802CS and ceramic cap, CP809. I replaced them with parts I already had and tested the rest of the parts that would've come in the repair kit and they were fine. I powered the board up on the bench expecting, in typical Samsung power supply board fashion, to see all my output voltages but, nothing. 0 volts on CNL801, CNM801 and CNT801. The only thing I have is 170vdc on the filter caps. No standby voltage either.
Anybody...
