One of my visitors was experiencing a problem with the laptop screen brightness after the screen replacement. Here’s how he fixed the problem.
I just replaced the lcd on my Dell C610 with one I bought from a reputable seller on eBay. Everything went well, but when I fired it up I found the display much dimmer than it was before. Checking part numbers, I came up with my old Hitachi TX36D98VC1CAC and the new part, TX36D98VC1CAE.
Here are some troubleshooting steps I went through:
1. Swapped inverters, but nothing improved.
2. I’ve got the keyboard brightness cranked all the way up. Didn’t help.
3. I’ve got the brightness in the BIOS cranked all the way up. Didn’t help.
4. Updated BIOS to the latest version. Didn’t help.
Finally, reinstalled the video driver and it fixed the problem. The new screen is as bright as before!
