      The problem is in the panel, try disconnecting the cable and look at the image on half the screen, the defect with stripes will disappear....

        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....

        IBM LTO 7 Tape Drive - Dust Sensors??
        by RetroComputingGrotto
        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...

        EIZO CX270 - No signal but Backlight and Panel works, logo works, admin menu works. OSD doesn't. What?!
        by vf fa
        Hi, so i guess I´ll have to make a new topic here, as i browsed through hundreds of other threads but couldn't find a solution to my problem yet.

        I got a EIZO CX270 from a friend. He said it doesn't work anymore and wont display any signal or take any OSD inputs. Well, as an aspiring photographer I couldn't say no, could I? Thought it was an easy game, replace a bad cap and have a working monitor. But nooope, it wasn't supposed to be this easy.

        So let me start with the problem description. I'll try my best not to skip anything so this might get rather long.

        LG 75UN8570AUD panel issue fixed with tape.
        by triplefour
        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...
