#REPAIR

[@albertoolmos21]

Many sites mention various causes for this common problem, from software, viruses, drivers, GPU, power components, and cables as in this case. On my old HP dv4 I already had to change the video cable and LCD in the last two years. Recently, the white screen issue appears randomly. So, I connected a monitor to the video output and found out that there is video on the monitor when the screen turns white, which indicates a connection problem. Now I need to find where.

Worked!! Thanks friend!

[@Wapaan]

Nice video bro thanks 🙂👍

Is contract cleaner the brush or is it a solution for cleaning

[@Dragonsmash20]

My laptop is Windows 10 and it does not work for me

[@youngachieversgthsgtc8146]

What is contact cleaner? Like for eye contacts?

[@Spoderman5000]

No, electrical contact cleaner. Comes in an aerosol can for cleaning electrical components. Not for eye contacts.

[@prkacro]

don't tell me it's because of the dust ??
greetings from Croatia !!
