4.0 Troubleshooting
4.1 Cleaning Method
The LCD-9084-301-x should be cleaned when excessive dust or dirt
becomes apparent.
Use a twin pack cleaning system that employs a wet pad pre-moistened
with an Isopropyl Alcohol based cleaner/anti-static solution and a lint-free

DeCrane Aerospace Audio International LCD-9084-301-x Installation Manual
Document # 540332, Rev A, 01/2009 Page 14 of 18
drying cloth. DeCrane Aerospace Audio International recommends using
“Kleen & Dry” RR1205 manufactured by READ RIGHT, Nanuet, NY
10954.
Do not use benzene, ammonia, thinner, or any other volatile
substance to clean the monitor or screen. These chemicals may
damage the screen or internal circuitry.
Do not allow cleaner to puddle or pool around edges. Seepage
may damage internal circuitry.
DeCrane Aerospace Audio International’s recommended cleaning method
follows:
A. Turn off monitor.
B. Open pre-moistened pad and gently wipe evenly across display
glass. Do not allow solution to “pool” or puddle around display
edges.
C. Immediately dry display using the absorbent, lint-free cloth. Gently
wipe display to a dry, clear finish.
4.2 General Troubleshooting Procedures
•Verify power to the unit by rechecking +28 VDC power is applied to the
proper pins on the unit. Use a voltmeter to verify correct level.
•Remove power from the unit for at least one (1) minute and reapply
power.
•Recheck all connections to the unit for security. Check all harness runs
for possible pinching. Recheck all pinouts for application accuracy.
•Check data bus integrity by utilizing a voltmeter, oscilloscope, or other
voltage instrument to verify proper input voltage on the data bus pins.
Typical measurements are as follows:
A to Ground: 4.0 to 4.5 VDC
B to Ground: 0.1 to 1.0 VDC
If any device is transmitting (i.e., holding bus active), then these typical
measurements would be reversed for the A-to-Ground and
B-to-Ground. This troubleshooting tool can help indicate a data bus
lockup. If this occurs, remove the data bus from all other equipment
one piece at a time. As each is removed, check the bus status to see if
it is now functioning properly. Once you have removed the piece or
pieces of offending equipment, disconnect power and then reconnect
everything but the suspect component. Reapply power and then test
the functionality of the unit(s).
