Out of focus and too brightly lit. But it appears to use a combined buffer. Some FETs on the third heatsink down blow.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Samsung pn50a450p1d Y board issue
Sorry for picture quality, I know its horrible. Have yet to invest in a camera that can take detailed photo. I have a surplus of boards out of broken tv's, might be a dumb question, but if its the same size and configuration. Why could I not use fet's off another board even though they are not that part number.Comment

Re: Samsung pn50a450p1d Y board issue
Because you can't use different parts when the circuit is designed for specific types, not all MOSFETs and IGBTs are compatible with each other.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Hi everyone,
Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.
Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.
I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue.... -
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.... -
Samsung LN46C630K1F – Intermittent Backlight, BN44-00341B Power Board
Summary for TL-DR readers:
• Backlight is intermittent, may come on with TV boot or not. No flickering, never fails during TV on.
• Have obtained Samsung schematic & service documents - Can upload if helpful.
• Have read ALL applicable threads
• C1818 and CP820 replaced as low hanging fruit
• CN802 data taken for normal and failed BL operation. SUMMARY: Pin 2 - 5vDet = 3.52 @normal, 0.0 @BL fail. Pin 6 - EPWM = 1.631 @normal, 1.058 @BL fail.

After installing Linux, I can no longer enter the BIOS of my Samsung Series 9 (NP900X3C) laptop. When pressing [F2] during boot I simply get a black screen. Same thing when pressing [F10] and choosing "Setup" from the "App Menu" tab. Apparently this is a relatively common issue with Samsung laptops of that generation, but unfortunately i haven't been able to resolve the issue (yet).
Things i've tried so far; reinstalled Windows 10, checked for redundant boot entries, tried to factory reset using the emergency keyhole, attempted to clear the NVRAM by physically...Yesterday, 09:15 AM -
Hi,
I have confirmed that I have a mainboard problem.
I have tracked no hardware issued on board so might be a software dump required.
I have searched a bit but wasn't able to find anything for my screen:
Here are some more details:
Panel: cy-nn065hgev1h
Main: BN94-14180M P08F
Your help much appreciated!
