I have a Hobart Digital Scale model 7930 that will cycle through its turn on mode but shows a blank screen from the scale any suggestions?

Question edited for clarity and proper order.

The only customer style resets are for presets that have been added, or for Tare. Any main resets can only be done by Hobart.

Located on the left side of the scale, to the right of the
Modnet port, is a small button. This is the Reset Button. If
the scale stops responding, use the Reset Button to reset the
scale back to the Start a Run Screen.
To reset the scale, PRESS and hold the Reset Button for 2 to
3 seconds.

It often just needs recalibrating. Try turning the scale on while holding the mode/tare button with nothing on the scale. Then press the tare button again. It should show a calibration weight which you should put onto the scale. Then it automatically calibrates.

Try recalibrating it by turning it on while holding the "tare" or "mode" button. It should show a raw data from the sensor then. Press the tare button again and it should calibrate the empty weight. Then it will show a specific weight you should put on, usually 100g. It should automatically finish calibration now. Hope this helps. The words before calibration on my scale was OUt2

"EE" means that the scale has been overloaded. Try placing a small weight (i.e. 250g block of butter) on the scale and then turning the scale off and then on again with the small weight still on the scale. What this does is to try and re-calibrate the scale. If this doesn't work then I am pretty certain that the scales will need to be replaced. The scales in question do have a 15 year guarantee and you can try contacting Salter Housewares directly if you have your proof of purchase.

Reset it!

Turn off the scale. Press and hold the MODE button and turn the scale on. Release the MODE button you will see the scale's internal count.
Press and hold the TARE button then press (don't hold) the MODE button you will see the full capacity is changing. Keep pressing the MODE while holding the TARE button until you see 100.00 on the screen. The reset is completed. You may need to recalibrate the scale after the reset.

Hi,
you need just to recalibrate it:
The procedure is standard for semi-all models of pocket scales, but the way how to get to calibration mode differs from model to model (or vendor to vendor).
In brief:
1.While turn-on get to the calibration mode (by pressing and holding the ON button, or holding TARE while turinig on) You should hold this "magic" combination until the LCD will show a number (large number - it was more than 2000 in my case). This number is a raw data from the sensor.
2.Now release the "magic" button.
3.Press it one more time, the display will show 2Ero and then 100.0
4.Now put calibrated weight of 100 grams on the scale and wait 3 seconds.
5.Press "magic" button again.The display will show CAL and then PASS.
6.Now remove the weight and turn off the scale.
7.Thats all - now you can use your scale as usually.

when i turn on my 4010.the screen display shows 4010 but thats all it does.any solution.

There are two display modes newly added for the DiMAGE 7i, grid and scale. The grid mode is to show a grid over the entire screen. This makes it easy to align the camera to objects vertically or horizontally. In the scale display mode, horizontal and vertical lines cross at the image center to divide the view to four sections, and each axis is scaled. This function is useful for close-up photography. The grid or scale on display is not recorded.
