Thank you for this information. I am having issues with my laptop monitor. Most of the time it is very dark, and occasionally it lights up. It seems to make sense to me that it could very well be the back light. I am not sure that I am confident enough to attempt to repair it myself, so I am thinking about taking it to a repair shop. I think it would be much safer for me to do so. Does anyone know of a good place to find a good repair shop? 613-742-7233 Thank.
