This seems like an easy temporary fix! After I got 4 bad DV boards from power sellers, I decided to try the heat gun trick. Is this laptop worth replacing the LCD screen? After that I just waited for about two hours and unplugged AC adapter from the wall. Santanu Sengupta December 28,

V December 3, It got really warm. I guess you are referencing another post where I fixed failed GPU with a heat gun. Loose connection between the video cable and motherboard or LCD screen. Then restart the PC. I tried a bunch of things with no luck. I was wondering if this method would work on video card as well, as some HP models are well known to have construction flaw that results in fail-chain: I think you are right, but for someone anxious to get personal data back or just make the laptop work for a while this could be a very easy and valuable solution.

However, dont worry, the processor can handle the heat. I do not have a warranty for almost viddeo years therefore they were hard to get!

OMG You are a genius my friend. It seems to me that if it was the backlight then it would have gone out gradually, not suddenly. The computer vudeo on and all LEDs light up but there is no video on the screen or external monitor.

Could the repair man messed something up.

Koala October 12, I never took one of these apart I think he messed something up in there. You just have to figure out for how long you have to heat up the GPU chip. You can tell if the back light is out simply by looking at the laptop screen, powered onin direct sun light.

By the way, if you are vide any damage to the motherboard, its ok, cause its the motherboard that needs replacing to fix this issue.

Had already dissasembled and thought what the heck Ill give it a try. The fix, on the Compaq V, lasted for about 5 days.

Or, could it be a bad inverter? Blanket trick, oven trick, heat gun trick. If I had come across this post earlier I will have safe that money. Hi, I am sakthi, I have one Compaq Laptop.

Select the Browse my computer for vv software option, and browse to the driver folder that was created when you ran the driver file. When the computer would get hot, as most laptops do, the solder would come un-done, causing ev connections to get loose, and bam!

Works great… although this is not a temporary fix. Romi January 23, Just tried this fix on my problem DV and it worked. I switched on for 1 hour and a half.
