    Turn the calculator on. Press and release the 2ND key. Press and hold the down-arrow key until the screen lightens. Does it?

Having gone over a month with no response to my query, I assume the suggested screen adjustment solved the problem.

Flash screen lights, then goes black, comes on with restart.


How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy.

Mag innovision LT716s monitor


When I turn on my computer the monitor takes a long time to warm up and colors change and vertical lines flash across the screen from right to left before the screen becomes normal again. Now the power light even goes out upon turning on my computer and I have to unplug the video cord and plug it back in to start the screen back up which even takes longer.
