Hello,

Tonight, I went to a friend who gave me a monitor he no longer needed, the HP 2159v. I get home, plug it in, and see that the screen turns on, displays the image for 5 seconds, and then turns off without going into standby. For your information, I tested it on both PCs I have at home, and it does the same thing.

Any idea?

Configuration: {Laptop} MS Windows 7 Home Premium 32-bit Service Pack 1
Intel Celeron CPU 900 @ 2.20GHz, 3.0GB RAM, Mobile Intel 4 Series Express Chipset Family ==> TOSHIBA SATELLITE LR-500

dying screen

logically, it’s the backlight that is failing

either the inverter or completely the fluorescent tubes in the panel

Theoretically, it's repairable, but it's a real pain to take everything apart to change a neon.

Change the neon?

The lighting of your screen is done (on slightly older models, now there are LED strips) by two rows of fluorescent tubes at the top and bottom

if one fails, the entire circuit goes into safety mode and there is no more lighting
I think that's what's happening (it's the classic failure): it turns on, detects an overvoltage, and goes into safety mode.

Do a search for "CCFL backlight" on Google, you should find what you're looking for.
