Someone has pressed the reset button at the back of the unit. The memory banks are being cleared and all settings are set to default. Wait until the process finishes (hour maybe) and till the "check code 191" is displayed. This means that the restore to factory settings is finished. After that you should be able to use the unit again although all your programs are lost.

Make sure the unit is unplugged!!!
I believe it is the lid switch. You can remove the housing and the switch is located adjacent to the latch. Test it with a multi-meter.I do not recommend bypassing the switch except to test it's operation. Serious injury can occur!!!

It sounds like the backlight of the LCD display is out. The Image is still being displayed there is just no light to illuminate the image. Try shining a flashlight on it (Put the light right against the screen) and see if you can see what's on the screen. The display is fairly easy to install but I do not know where you can purchase one directly.

Could you send user manual of dynatech microplate reader mr700 to me please?

Is it filled with water? If yes, then the liquid level sensor has failed in the unit. This will happen normally, but does happen frequently if you have growth in the water reservoir. Call for service. Follow instruction in the manual about flushing the reservoir.
