HP Pavilion DV5 Blank Black Screen

Reflow NVidia

HP Pavilion DV5 1110el not turn

 

Details:

The PC will not turn on. Pressing the power button, the LED turns on and the screen lights up but sometimes does not show anything.

In some cases, the power LED lights up for a while and then go out again and still the screen remains black.

The cause may depend on several factors: in this case, I show how to completely dismantle this PC and then fix it by reflow nVideo video chip on the motherboard.

There is also a version with ATI video chip that suffers the same problem (see my other article).

At this point I started the stage rework processors starting to prepare the motherboard.

I unplugged before any rubber part on the motherboard, then I cleaned meticulously processors and all components.

The phase of the repair included a reflow of the video processor and nVidia chipset with the usual procedure: I made a preheat to 150 °, eliminated the red silicone present on edges of processors, forced the flux between the solder ball and subsequently led the 2 processors at about 210 °.

The risk in this case was the absence of the temperature curves for one of the BGA for which I improvised: however the result was excellent.

 

 

After making the rework of the motherboard, I proceeded to clean the fan and heatsink then I proceeded to change thermal paste and began to reassemble everything.

 

After reassembling the pc is magically come back to life …
