A very large BenQ screen, approximately 50 to 65 inches. The screen is very large, its version is a bit old, but it serves the purpose. It has no problems except for a problem that appeared two days ago. When I turn on the screen, the light and everything turn on, but the screen does not turn on. So its problem is very simple, but I don't have the ability to fix it and I decided to sell it. Its problem is likely in the board. ""Selling to the highest bidder."" Only serious buyers should bid.
