Hi, is there anyone that have made the little investment of buying an ACF tape coil to repair lcd screen's tab bonding issue and want to sell some meters to others? On aliexpress it is sold at 85 euros/coil. The soldering iron tip to heat the tabs costs approx. 5 euros per tip. Bye..

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... -
Problem
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'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 have old game console which have connected to 220v outlet by previous owner and It is not able to turn on.
I checked continuity of fuse in PSU unit with a multimeter which is shown in the below picture with a orange circle around it, and It seems that fuse became open circuit.
I also found that as well as bulging capacitor, there is unidentified coil which has residue all over its surface

I want to replace this round black fuse and unidentified coil if it got broken.

Hi everyone
I'm struggling to point out what part is this? It is a coil, but the parameters say: 10OHM - 50% - 1A - 0.05Ohm
So it is a coil with 0201 dimensions, 1A max current, 0.05ohm resistance but what is 10ohm? For a coil we need specs like 1uH or so.
IAny ideas? It is from a MacBook A2681
Thank you...
