I have an HP dv6 laptop that has suddenly started displaying very dim video. Even upon booting the splash screen with the HP logo is very difficult to see. I have replaced the LCD and the video cable with no luck. What should I try now and what could be causing this problem?

Thank you!

This could be the video chipset on the motherboard slowly failing. A couple of things I would try:

1. Shine flashlight on the LCD to see if you are able to see the display/icons/text any better. This will help you in figuring out what the issue is whether it is the back light in the LCD.
2. Plug in an external monitor to see what the display looks like and whether or not it gets any better.

When you say you replaced the LCD where did you get the LCD screen at? Was it purchased brand new or used? Since you replaced the cable have you tried to reseat (unplug and plug it back in) the video connection to the motherboard?

i have repaired quite few of these; in all cases, i had to reflow the video chip
i have used a heat gun (paint stripper) and pointed it to the chip
all worked again, after this treatment
if you want more details, just ask

The LCD is new purchased from an authorized HP vendor.

I get perfect video on an external monitor.

Shining a flashlight give very minimal improvement.

More details on reflowing the video chip would be nice. I do have a heat gun.

ok
i open the laptop, to take out the board completely
i have made a fixed setup for the heat gun, to point it to the board, for 10 minutes (for mine)
**as an indicator, i put a bit of solder in a beer capsule - to verify when it melts - and count at least 5 more minutes

then let it cool down for 1/2 hour and test
