Question about BenQ FP71E 17" LCD Monitor
The monitor fails during use, timing is straight away to 5-6 hours after switched on. When it is about to fail the display goes darker and then it goes to black. Then it must be left for a while before it will work again. Please help
Hi, From your description/post, it would seem that something is overheating in your monitor. It is possible to be a cold solder joint or a component starting to fail. Since this involves component level repair, use of a VOM and a soldering iron, it sort of limits a do-it-yourself repair not unless you are comfortable working in such an environment and with such tools and equipment. A sure sign of cold solder though is if when it is jarred it turns itself on. The "growing darker" possibly indicates backlight fading. You may need the services of a qualified professional to have this repaired. Good luck and kind regards. Pls post again should you need further information.
