Hi guys!
After a couple of years my ProBook 450 g6 screen has this issue: every 2 seconds it turns from normal to pink/green colors, with horizontal lines on the screen and distorted images. I’ve disassembled it and everything seems to be ok: I’ve touched the flat and both connectors with the computer turned on, but the problem is still there.
Anyone can help me to discover the issue?
Thanks in advance for the reply!
Hi @ds_1 , Things to try: a. Try entering BIOS on startup and check if the problem is still there. Press F10 on startup when (if?) the HP logo appears. This is to determine if it is an OS software problem or a hardware problem. b. If it doesn’t occur when in the BIOS menus then try starting the laptop in safe mode and check if it happens. If it doesn’t happen when in safe mode then there is a driver problem. Check that the display adapter drivers in Device Manager are up to date and that it is installed correctly c. Connect an external monitor to the laptop and check if the problem occurs on it or not. Press F1 to toggle between the displays i.e. laptop only, both displays on together, extended display or external display only If the problem is still there on the laptop screen only, then most likely it is a screen hardware problem, display cable or LCD panel. If the problem occurs on the external monitor also it is a GPU or motherboard problem If you determine that the problem is with the LCD panel, here’s the maintenance and service guide for the laptop. Go to p.24 (non touch screen Item #4) or p.25 (touch screen model Item #1) to find the part numbers for the LCD panel. Search online by typing the appropriate to your model part number only, in the search box of your browser to find suppliers that suit you. Usually the part number can be found on the back of the LCD panel somewhere, if you wish to verify that you’re ordering the correct part. The manual also details the necessary pre-requisite steps and then the procedure to remove/replace the panel.
