Title	Replacement of the display panel and flex cable replacement
Introduction	In the ENVY 15 j100el model the graphic card [https://www.geforce.co.uk/hardware/notebook-gpus/geforce-gt-740m/specifications|GeForce GT 740M] can provide an LCD display connected through LVDS interface with a resolution up to 1920 x 1200 with the easy withstanding of [https://ark.intel.com/content/www/us/en/ark/products/75117/intel-core-i7-4700mq-processor-6m-cache-up-to-3-40-ghz.html|the processor] which can handle bigger resolutions also. So, if you have to or if you want to replace the original [http://www.panelook.com/LP156WH3-TLS2_LG%20Display_15.6_LCM_overview_19066.html|LP156WH3(TL)(S2)] LG panel display which has a native resolution of 1366×768 (HD), since the fact that your hardware can support it, you could consider to upgrade the display to a Full HD with a 1920x1080 (FHD) native resolution. === The new display should have these characteristics: === * Size: 15.6" * Form Style: Slim or flat * Signal interface: LVDS, 40 pins connector (1 or 2 channels) * Operating mode: transmissive (it can be then either normally black or white, either IPS or TN also) * Frequency: 60 Hz * Input Voltage: 3.3V * Light source: White light-emitting diode (WLED) with LED driver * NO touch screen Besides the precedent restrictions you are free to choose about brightness, viewing angle, display colors, surface treatment, contrast ratio, response time, resolution (the latter one up to a max of 1920x1080 due to the graphic card) and so on. The best display panel that this HP model could afford would probably be the [http://www.panelook.com/B156HAN01.0_AUO_15.6_LCM_overview_19047.html|B156HAN01.0] produced by AUO due to its wide viewing angle, IPS technology, high contrast ratio and better color performance but this screen was only produced until 2013 and it’s hard to find nowdays. I managed to find this panel on eBay and the result was really good - viewing angle and colors were fantastic - but unfourtunately it was not functioning in the middle (a black stripe was appearing there). So, in the end, I installed a [http://www.panelook.com/B156HTN03.3_AUO_15.6_LCM_overview_23124.html|B156HTN03.3] which is not as good as the HAN01.0 but a whole lot better than the original LP156WH3TLS2 display —> choose your best one! '''If you only want to replace the display panel jump directly to step 13 and''' try to install the new lcd without opening the laptop base. It’s quite diffucult because two of the four screws that secure the display bezel are hard to reach but you can manage to loosen them somehow. Anyhow, if you do this, you have to '''remove the battery anyway'''. When the screen is disconnected and the display cable is free to move, it’s easy that it makes a short circuit coming in contact with the ground somewhere. It happened. === About the flex cable: === My screen was fleckiring. HP P/N: 720536-001.
