Hello and thank you for your question, I look forward to assisting you today. How old is it please?
Thank you. Can you see anything at all on the screen? Is it dim or totally dark?
Okay, the flashlight is the trick I would have had you try. There is a small back light embedded behind the screen that illuminates everything you see. These will eventually fail or burn out just like any light bulb. The only thing you can do is to have it professionally repaired, and depending on what you originally paid, it probably wouldn't be economical to do so.
Well, I guess there is no other way to say it, but, yes. How much did you pay for it?
I would be happy to continue working with you if you would like to continue. Please let me know.
