Question about HP Compaq Presario R4000 Notebook
Always. How do I brighten the screen?
you must replace your lcd inverter, you can obtain one for around 5-15 usd, you will need to open your lcd bezel(plastics)this it a common problem in this model, its easy just be carefull with your lcd. The inverter it is located under lcd, you need to remove the frontal plastic, locate the inverter and replace it. The dark it is because your inverter no longer turn on your backlight(a lamp to give brightness to your lcd inside your lcd)
This could be a hard work if you didnt have the tools or experience.
If you wish we can replace your inverter for $49 usd
