The Robinair 34788 is an automotive air conditioning service machine that features a large, easy-to-read display. If the display on your 34788 machine appears dim or the contrast is not suitable, it is possible to adjust the display contrast to improve visibility. Here are the steps to adjust the contrast on the Robinair 34788:

1. Turn on the machine and wait for the display to fully light up.
2. Press and hold the "Enter" and "Clear" buttons simultaneously for three seconds.
3. The display will show "Contrast" and the current contrast setting.
4. Use the "+" and "-" buttons to adjust the contrast to your desired level.
5. Once you have set the contrast level, press the "Enter" button to save the setting.
6. The display will show "Contrast Saved" to confirm that the new setting has been saved.

If you are still experiencing difficulty with the display after adjusting the contrast, there may be an issue with the machine's internal components or the display itself. In this case, it is recommended that you contact a qualified service technician for assistance.

technically it is both it's just people get confused with dynamic contrast and static contrast. The LCD LG5000 Series (00,20,30) has a
[dynamic contrast ratio of 50,000:1]
this would typically be
[15,000:1 contrast ratio] for a plasma.
so to count for, lcd tvs use dynamic contrast and plasmas use static contrast it's just a way to measure them both.
like people weighing themselves soem weigh in kg some in pounds =p hope this helps.
