When inverter fails, the screen goes completely dark and the image becomes very faint, but from your description your screen lights up, so the inverter is good. You can see the distortion on the screen and itвЂ™s bright, right? It means the backlight works fine and there is nothing wrong with the inverter. Want to know if I need to order a new screen inverter also? How can I check to see if mine is ok? YouвЂ™ll have to replace the video card which most likely is a part of the motherboard, so youвЂ™ll have to replace the motherboard. If the same problem appears on the laptop LCD screen AND external monitor, there is something wrong with the video card and replacing the screen will not fix it. If the problem appears only on the laptop screen, but external works fine, you might have a problem with the LCD screen or video cable.Дў. The screen was working great and then I walked away and came back 5 min later and the colors are now all distorted.Д«efore buying a new screen you should have tested your laptop with an external monitor and find out if the same problem appears on the external video.ДЎ. To be honest, I have no idea what you are talking about. I purchased an all-in-one cable (XC1000) which attaches to the the display port and supposedly bypasses the often mentioned power port problem, but this didnвЂ™t help. If itвЂ™s loose or broken, it has to be resoldered or replaced with a new one. ItвЂ™s necessary to disassemble the laptop and take a closer look at the jack. I believe in this laptop the jack is soldered on the motherboard. This could be related to the DC-IN power jack. I also have an HP zd7260 that usually shuts down immediately after power up and it wonвЂ™t recharge the battery In most cases you cannot tell if laptop parts work properly simply looking at them. IвЂ™ve removed the inverter and LCD to determine if thereвЂ™s a short in either the wiring or on the circuit board, but I didnвЂ™t see anything obvious. Sounds like you have a problem with the LCD screen and it has to be replaced. When I press on the LCD bezel where the inverter is mounted the display usually comes back to life. Which has a problem similar to the very first photo on this page, however the top 1/3 (sometimes the top 2/3rds) always works just fine. I can publish your guide on this site so other people can benefit from your experience. If you wish, you can take pictures during the disassembly process. I guess $80 is not expensive for a new screen. In case of failure, you can through it away and purchase a new screen. You can find a new backlight for about $10. If you have nothing to lose (without backlight your LCD is not usable anyway), you can try replacing the backlight. I will probably buy an inverter (as itвЂ™s cheaper) to see if thatвЂ™s fixes the problem but in the event that it is a backlight problem does the complete LCD screen have to be replaced or can the Backlight be removed from the screen. ItвЂ™s very likely that you have a problem with the inverter board and there is nothing wrong with the backlight lamp. Sometime the LCD screen flashes on for a few seconds but goes dark again. I have a HP Pavilion dv6000 and the screen is dark (I can just barely make out the Desktop icons). ItвЂ™s very easy to damage the LCD screen while taking it apart. The backlight lamp is mounted inside the LCD screen and youвЂ™ll have to take the whole thing apart.

Just wondering if the backlight can be easily removed from the LCD screen. This guide should fit HP Pavilion dv6000.

UPDATE: In one of the next guides I explain how to completely disassembleВ the laptop. I found them in the official maintenance and service guide.ДЎ5.4-inch, WXGA, SVA display panel with BrightView (Glossy) 431386-001ДЎ5.4-inch, WXGA, SVA display panel AntiGlare (Matte) 431387-001 The following part numbers for HP Pavilion dv6000 could be helpful to you. Now you can remove the defective LCD screen and replace it with a new one. Remove two screws from the right mounting bracket. Simply unplug the cable from the connector. Remove clear tape covering the connector and disconnect the LCD cable. Now you can get an access to the back side and access the LCD cable. Remove two screws securing each display hinge/bracket. The left cable supplies power from the motherboard and the right cable connected to the backlight lamp inside the LCD panel. Disconnect cables on both sides of the inverter.

Now you can get an access to the inverter board which is mounted on the lower part of the display assembly. Be careful, the bezel made of fragile plastic.
