Excess shine | After a review, it was found that the excess brightness was caused by an incorrect screen adjustment. It was thought that someone was inadvertently adjusting the screen by inserting a screwdriver through the hole in the cover. but it was when closing the device that I realized that the lid applied pressure to the focus and screen potentiometers, causing the controls to rotate involuntarily. | The solution to the problem was to modify the lid so that it does not press the focus and screen controls with the device closed. | Carlos André Poloni |
