Taped on Connectors
Whats the best way to get tape off a board holding down a cord, without ruining the pins on the board? I've already toasted a T-conboard via reflective mylar looking tape, and I foresee the same happening to a $100 LG 47lb5d Mainboard too.

This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
I have a Quantum SuperLoader robotic tape library that uses an IBM LTO 7 tape drive which is constantly complaining that it needs cleaning. If you insert a cleaning tape, it performs the clean and resets the cleaning counter to 0 hours. It should only require cleaning every 50 or so working hours but after as little as just 1 hours use it requests cleaning. We've purchased a new cleaning tape along with new LTO backup tapes but that has not resolved the problem.
I have taken the library apart and can see no noticeable signs of dust inside. I have removed the tape drive from the... -
I've been seeing a lot of the new TVs (samsung and LG only i think) maybe 1-2 years old suffering from sudden panel death and have been over 50% successful bringing them at least most of the way back to functionality if not all the way, with the tape masking of the LVDS pins method.
add this one to the list. the issue was on the left side of the panel and i ended up blocking just 3 pins on the connector that joins the two panel boards that make up the left side of the panel (it has 4 boards total) i didnt get the picture back to 100% perfect. i spent hours fiddling with which pins to block...07-17-2023, 10:22 PM -
I’ve had and got a few projects using quality CAT6 and CAT7 23awg solid copper, shielded, direct burial cable. Each time I use CAT7 connectors, most of them fail making good connections to the 4 wire pairs after crimping. I tied a couple of crimping tools, thinking my crimper is bad. Also used different CAT7 RJ45 connector manufacturers. Same thing. I kinda calculate 6 connectors to make one cable!
Get this: I use CAT5 or CAT6 connectors, no problem. Very rare I have a miss crimp with those. So what gives?!

I have a number of laptops with damaged USB-C connectors.
I wonder if I can buy a few replacement connectors from Mouser to keep, as it seems like the wafer in the middle breaks easily and oftentimes causes shorts.
I do know there are multiple connectors out there, but I'm curious to know which are most commonly used and how can I identify and purchase the correct ones.
I purchased USB mini-B connectors in the past, only to find out that the connector was flipped (Lenovo smh).
