Try attaching an external monitor to the laptop & see if you could get any display on it. If this is successful, then you might have either a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp.

I took my HP Pavilion dv7-1132nr on vacation with me and the monitor sporadically goes black. I thought it was in hibernation but I cannot get it to go on. I do a hard stop and after about six or seven...


This is most likely either an issue with the display itself or the cable that is inside the laptop chassis that connects the motherboard to the display. The cable can get pinched and unplugged by the screen being opened and closed (if it wasn't assembled properly). This can be about a $200 fix. If it is the display itself cutting out completely, it is typically over $350 to repair through HP. If there is a dark, washed out image that is barely visible, it means the backlight is going out and that is at least a $300 repair.

Screen not sharp. colour combinations only 32 bit. Suspects the wrong VGA driver for the HP 8430 Laptop was installed. Needs the right driver.


Make sure the screen is set for 1680 x 1050 when you right click on the desktop and go to Personalize... Display Settings. If it is set higher or lower than that it will look fuzzy and weird.

If you would like to reinstall the driver it is here:

Just select the OS and go for it.

HP TC4200 tablet pc. Screen keeps going dark, can JUST make out characters. Happens more frequently on AC power, lesson battery. Resolved by closing and reopening screen hinge. When connected to external...


Do what you can to rule out the tablet's firmware and power-management software being dotty (by refreshing those installations.)  Just in case, put an order for a replacement backlight in (from HP, who can at least let you on to the part number, or elsewhere...) and have a flatscreen handy to use as a spare display if the internal one gives out on you!

Oh!  And file questions like this in a non-general category so you can get answers sensible to HP tablet PCs!

Monitor display is not visible


If you can see the screen, but it is very dark/feint, then you will need to have the inverter replaced.
Look for a local laptop shop in your area. They will be able to do the job quickly and easily. Price wise, it will vary from shop to shop, so call a few first.
