Laptop LCD Screen Repair

I got a parts/repair computer off Ebay for $20 to support my fleet of Toshiba CL45's. After a BIOS reset, I found that the computer worked except for the LCD panel's LED backlight. The screen was dark, but if you shined a flashlight at it you could tell the screen was working. Plus, it put out a working HDMI signal to a TV set. There is little to no info on repairing these, so I was about to start swapping LCD screens with another laptop to isolate the problem. Finally I found this Russian guy's video at which gave me just enough info to determine that my LCD panel had a tiny blown SMT fuse on the 19V side which powers the LED backlight array. A bit of multimeter probing, a tad of soldering and I'm back in business now. BTW, used replacement panels are available for most computers for $40-60. I wonder if many "bad" panels simply have a 2-cent blown fuse. If so, this problem is just as significant as the bad capacitor issue that makes people throw out TVs and monitors after 3 years. Never say die!

  • If you think those are trivial reasons for tossing laptops in the land fill checkout Louis Rossmann on what Apple is up to when it comes to repairing their stuff:

  • Pretty sad! Somewhat like Tesla's monopoly on parts & service. This guy Rich is famous for fixing and frankensteining salvaged Teslas together by brute force, trial & error. Tesla doesn't condone his efforts and won't even talk to the guy. He perseveres anyway and has quite a Youtube following.
