HP Envy 15 No Picture Repair after a drop

Once in a blue moon, we get straightforward repairs like this HP Envy 15 No Picture Repair after a drop.

This HP Envy had a slight drop, which was enough to render the screen black and not show any picture.

Fault Diagnosis of HP Envy 15 with No Picture

The first quick test we perform to ensure the system is still responding is the see if there is a response from the Capslock key. If it lights up on press, that’s an indication that the system is performing well, but our video output is not working. This narrows our suspects to either an LCD fault or a Video Output fault from the system.

Since this model does come with integrated Intel Graphics, we can eliminate GPU failure and head straight to check the LVDS connector.

LVDS connector however seems connected fine and not being loose. As a matter of fact, very rarely do we have a situation of a loose connector at this end as it is clipped securely.

Our next suspect is the other end of the screen cable. Which also usually doest come loose by itself, unless someone tempered with the screen. To check this we have to take the touch screen assembly apart. Luckily with this model, it is easier than the notorious Lenovo Yoga 730 which we dealt with recently for a hinge repair.

Once screen assembly came apart we could safely check if it was connected properly as well as run continuity check of the lines within the cable. It is also a common failure point. Especially if it was strained and internal lines snapped.

On a close inspection of the screen side of the connector, we could see that it was slightly pushed out.

Even with a pushed in screen cable we still haven’t got the HP Envy to provide a picture.

Repair Process of a Envy 15 No Picture after a drop

We quickly realised that the bent LCD connector pin must have shorted something on the motherboard. And in particular the backlight/screen circuitry.

We have a sophisticated equipment workshop with high accuracy microscope, ultrasonic cleaning bath, reflow machine, and tools for micro soldering to achieve high-quality logic boards repairs. With thousands of components in stock, we quickly locate and replace failed components!


Please note: This is not educational material. It is rather a showcase of the services we offer.
Therefore, it should be used as general guidance on what to expect of such repairs.
In case you have a similar device and need the repair, always rely on professionals. These are sensitive electronic devices, and small mistakes may cause irreversible electronic damage. Which may require whole part replacement for 2 or 3 times the cost.

The next suspect was the video output and backlight circuitry. So we start measuring for short circuits or blown components. And it was not long before we identify misbehaving component.

Luckily the short caused by “doggy” previous screen replacement followed by an accidental drop was caught by a fuse. This little black fuse protected a vital IC from burning. However, these are SMD fuses and are not mounted on a slot that can be pulled out and replaced easily. Hence it required some Soldering work in our Adelaide Laptop Repair workshop.

And there we go, screen brightened up as soon as we fired the HP Envy and behaves as expected.

One little thing was left which bothered us. Probably most of the companies would have overlooked it. But this is our way of fighting with planned obsolescence and our commitment to Repair, Reuse, Recycle, Reduce the target of keeping Australian eWaste out of the wastelands.

Cleaning and oiling these hinges we felt was our obligation to ensure longevity. Otherwise, customer would have well-known hinge support failure as we often get with Laptops Broken Hinge Repairs these days. Even only after less than 2 years in service.

There we have it a successful HP Envy 15 No Picture Repair with encountered a fall and its screen turned black. We do not name and shame, but honestly whichever company has replaced the screen coupe years ago should have secured the screen connector in place. They haven’t! As a result, a drop pulled the screen cable out and shorted screen voltage lines. Luckily there was a fuse to catch the short and sacrificed itself for this glorious HP Envy 15.

To ensure such issues will not happen easily we secured the connector in place. This is how it should be done, guys!

Repaired, not Replaced!

We are committed to reducing e-waste in Australia. How we do it is by educating our customers on the repairability and longevity of their devices, as well as providing affordable Laptop Repairs here in Adelaide.
Although our best intentions and hard work, this is not an easy task. Customers must accept that cost of high-quality electronic repairs, is between a third and half of the price of a new device. However, with the current trend of planned obsolescence in electronic design, we see more and more Laptops having shorter lifespans. To tackle that, while we do our repairs we target common planned obsolescence engineering design mistakes to ensure we extend the life expectancy of the Laptops we repair. Check some of our Laptop Repair Cases to get an idea of the process.

That said, if we buy a new one or write it off via insurance, it does not guarantee that the new one will not meet the same fate as the older one pretty soon.
As matter of fact, quite often we see accidents reoccurring within less than 2-year gaps. If we can save 1000$ or even 500$ today by repairing our faulty Laptop is great. That’s an extra half Laptop cost ready to be spent on another one when the time comes or our need for performance increases.
When that time comes is up to us to buy a new one or keep pushing the one we have, but delaying it by a year or three is always a good starting point and saves another abandoned Laptop from polluting our one and only Planet.
