I was about to choose a car relay for you that have 30A contacts that make really loud snap noise... and dump intense inductive feedback into delicate electronics... but decided not to, and instead chose something from China.Last edited by eccerr0r; 06-01-2016, 03:56 PM.Comment

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.... -
Hello, I search this connector (oxydated).
It's a fpc zif low profile connector. It come from camera sensor, it is very small : 0.3mm between 2 pins.
I ordered 2 from Aliexpress called « 0.3mm pitch » but one was 0.5mm between 2 pins and the other 0.6mm. In fact « 0.3mm pitch » seams to be the pad width and not the distance between 2 pins.
I can't find it. The other websites like mouser dont show the datasheet, and I can't check if it is 0.3mm between 2 pins ?
Do you know how to find this connector please ? What is the exact name for find it ?

Hi everyone! I'm trying to fix my black screen / failed U8900 GPU v-core on my Mid-2012 Macbook Pro 15" Retinaby doing a rework/reflow of the chip (once I determine that's the real issue; but it likely is).
I've been disabling the GPU in NVRAM for a few years... but it's just time for a better solution.
I'm new to soldering but the only feasible way to fix this issue is to do something myself.
MY QUESTION:
I've been seeing some people (on this forum mostly) run into issues with the logic board needing a serial number or it being deactivated (?)... -
Hi all, I just want to share the repair of my 60PK550-UA TV set.
The TV set was powering on, just no image. After verification, nothing wrong on the YSus or ZSus boards. Nothing wrong on the main board either.
But I noticed that the LED was not flashing on the Logic Control Board. This is an EBR63450301. The LED is supposed to flash even with all the flat cables disconnected, with only the power cable attached.
All the voltages measured at the electrolytic capacitors on the board were good. From top left to bottom right:
C57: 3.30V
