I have purchased a MST-9000 and have been trying to use it and screen display has locked up to a
solid blue (no text).
Initial use was fine, the wakeup with
power on to a splash screen, the menu worked and buttons responded. Power
on/off a few times and no issue.
The SW was loaded to computer (XP OS per
instructions) and the SW loaded fine. Drivers for the MST-9000 USB connection
were found through connection, manual find and all was OK.
An initial waveform was loaded to the ECU
software, saved to the disk.
After connection of USB from MST-9000+ to
the computer as stated above the MST-9000 is locked as shown in pictures below.
Only the on, off and read buttons have any
effect now. The on is on, off is off, out and read beep at me, but read turns
on CH1-5.
Also the 5V, 12V, and 24V buttons activate
lights, gages work too for Volts, etc.
Is there some reset or return to default
condition on this MST-9000. I have read the manuals with the CD(PDF’s) but
don’t see a way to restart in initial condition. Or a SW setting in
the ECU software that allows the reset, etc.
I tried to power up the MST-9000 and its doing the same issue for the display
today. Please reply with a status of your recommeneded fix or resolution.
If you need any other information on
button press/hold or a sequence of buttons,, etc. to unlock or get a status of
this instrument let me know.
A: Please check the power + – whether connected
right?
Q: I tried this on four plugs at my
bench (computer, monitor, Voltmeter HP3478A, and the MST-9000). All work fine, but the MST-9000 is same issue of solid lighted display.
No splash screen or transition on startup visible (I looked).
Tried on same plug I initially used it for
first power on/off’s. Same issue is present now.
With this MST-9000 plugged in and on I get
a tone(whine) of higher frequency that is like a driver or display upcoverter
to operate the display(commonly used to have flicker free perception of the
displays and backlighting shown on this LCD). Whine is only present with the
LCD light, not the 0.3 sec transition of the lights off on rest of MST-9000.
Yes I am an engineer and try to observe
critically what happened (used to this from work).
Please reply with a next step or how to
resolve this issue. Really want to try this MST-9000 out as an engine
simulator. Thanks.
A: Does the light flashing after you connect
power?
Q: No lights on or anything happens(lights,
sound or anything I can detect), until the on button is pressed.
Then a solid lamp backlit on the LCD
display, no transition of the light, display or change unless its so fast I
cannot detect it.
Tried at angles for twist of these
displays and no change or “hidden” letters I can detect off angle(left, Right,
up, down, etc.)
A: Engineer ask you change a crystal
oscillator next to the Main board CPU. Can you do this?
Q: I have opened up the case and looked over
the board and parts with a technician at the office. All the functions of power
supplies, outputs to board for power, operations of the rotary knobs (pots,
voltage dividers, etc.) are correct from what we saw and measured. The display
was stuck in the lighted position and I had found the processor and crystal.
Tried to press, touch for heat and no change on the operation. (Picture
photo.jpg above of the uP and crystal) After a few tries the technician used electronics
cooling freeze and cooled the processor and crystal. This had the unit recover
function of display to menu and a beep of speaker. All was OK and good. Worked
with it for a few minutes to see if the heat of operation would cause the
failure again. Did not fail quickly so he used a hot air gun(controlled temp on
very low setting) and tried to heat up a bit. A few increments up to the
roughly 70-90 deg c by feel of hand and it failed in same way again. Then
cooled the crystal down and back to operation. So we believe it’s the crystal
as you had indicated. The CD you provided has many PDF’s and I have searched
this but don’t find a crystal oscillator spec sheet. The code on the crystal
says 11.0592, I can find these easily in NA market with the leaded type used. A
supplier of Newark Electronics has several available below to order
Can you provide the specific frequency
tolerance, load capacitance, frequency stability and dimension for spacing on
this part(4.0 or 4.06 mm). Or can you ship some of the crystals used and will
change this here. We can likely change this here as its wire lead part.
