Fixing a dv6000 with a Horizontal Line on LCD Screen (In Surrey)
I traded in this dv6105us on 2July2013 in Metrotown Library. It was in bad condition. The owner showed me that it could be powered on. It did not have charger, battery and hard drive.
On the weekend, I inspected the laptop. The left hinge was broken. The top right corner of the screen was missing. The bottom cover on the heat sink vent was broken. When I powered on the laptop, the screen near the middle had a horizontal line.
I disassembled the laptop and found that the USB port on the left side was broken too. The laptop fan was clogged with dust as expected. I cleaned up the fan, applied new thermal compound to CPU and replaced the old thermal pad bya new one on the GPU.
To fix the the horizontal line, I disassemble the LCD screen. On the ribbon near to the horizontal line, I flipped out the adhesive tape and used a plastic stick to probe in the gap between the LCD ribbon and the metal frame. When the stick was in the right point, the horizonal line disappeared. I cut a piece of foam and insert it at that position. I assembled the screen and the horizontal line was gone.
For the broken covers, I replaced them all, i.e. screen cover, screen bezel to match with the screen cover and the bottom cover. It has an extra USB port, firewire port and SD card holder than the original one. They have space reserved on the motherboard. I replaced the broken USB port and added the missing ports. In my testing, the new ports did not working. I covered up the added ports by a plastic sheet.
From preivous dv2000, there was a 120GB hard drive which has bad sectors at the beginning of the disk space. I created a bad partition for them and another partition for installing the Operating System.
During testing, I fried the ribbon to the speaker panel which I did not connect it when powering on the laptop. I replaced both ribbons.
Testing the wireless, it did not work. In a month, the horizontal line came back. The owner gave me the charger later on but the wire to AC had problem inside. To continue fixing this laptop, I bought a wireless card, a brand new screen, the wire from AC power outlet to the charger.
After fixing the laptop, I installed Windows Vista on it. It was picked up by a nice man from Surrey on 18Sep2013.
