Have you checked the voltages for the red video output from the video processor? Also check and see if the LCD array responds to signal input directly.

Display powers of with power up of AVC


how many blinks does the red light give in a row? This would be an error code?

The problem for 7 blinks would be an Interface board. Apparently there is a glitch in the interface board that sends signals to the television. Basically the glitch shorts out the board and the t.v wont turn on and you will see the power light blink 7 times pause then 7 more. You can replace the board with a new one and update the software on the new interface board.


If is isn't 7, let me know and I will help you out with this

thanks

When i plug my treadmill in the digital display wont read or turn on


1)ADJUST THE SENSOR REED SWITCH BY 1/8" SEE THE DIAGRAM
2) IF YOUR SISTEM HAS BATTERIES EXCHANGE BY NEW ONES.
3)TIGHT THE FLEXIBLE CABLE FROM THE KEYPANEL VS DISPLAY BOARD AND THEN TIGHT THE CONNECTOR FROM THE DISPLAY BOARD VS LOWER BOARD OR MAIN MOTOR CONTROLLER BOARD.
4) WILL BE A GREAT IDEA IF YOU CAN MEASURE WITH YOUR VOLTEMETER +5VDC coming from the main motor controller board to display board.
Now if there are missing the fault: is main motor controller of course after you did the first step or the voltage is there the display board is faulty.

12_6_2011_1_18_12_am.gif12_6_2011_1_18_35_am.gifsee the block diagram how the main motor board control by 90percent of function of the any treadmill. Good luck, sincerely. G-d bless you.

This is from the MANUAL
www.westinghousedigital.com/pdf/197_User_Manual.pdf

PAGE 27

A-1 Settings
Use the Settings sub-menu options to manually adjust the display quality. Use the ◄/► keys to adjust the

AND this is from the troubleshooting procedures in the manual

・ If any colors (red, green or blue) are missing, check the video cable to make sure it is securely connected. Loose or broken pins in the cable connector could cause an improper connection.
・ Press and select Picture | Settings to adjust the Hue and Saturation settings. You can also select
Picture | Advanced to adjust the Color Temperature settings.
・Connect the TV to another computer and check if the problem is with the computer screen.

Convergence problem


This is out of the service manual

don't forget to write the setting to rom by hitting the pip button twice

Good luck and don't hesitate to ask questions






2.12.5 Convergence point adjustment
Adjustment preparation
(1) Select color to adjust.
“STATUS” - Green
“0” - Red
“ANT” - Blue
(2) Use 4, 6, 2, and 5 to move the cursor position
(dotted lines).
(3) Use thumb stick to move the convergence point.
(4) Three adjustment modes are available:
1. (3x3) Press “STATUS” 5 times (only works
when DCU is in uncorrected state)
2. (7x5) Press “0” 5 times
3. (13x9) Press “ANT” 5 times
For touch-up, only the (13x9) mode is necessary.
This will adjust every cross-hatch intersection point
on the screen.
For complete adjustment, start with (3x3) mode. This
will adjust center point and eight edge points only,
but will greatly reduce adjustment time. Then use
(7x5) mode, and finally (13x9) mode to finish
convergence.
If “S” distortion appears between cross-hatch lines
repeat (7x5) mode to change calculation process
while adjusting to remove distortion, then return to
(13x9) mode to finish touch-up convergence.
Adjustment procedure
(1) Receive any NTSC signal.
(2) Start adjustment at the center of the screen.
(3) Continue adjustment at next closest position.
(4) Adjust center area first, ending with edge sections.
(5) Press INFO button to perform calculation operation.
This process will take about 2 seconds and no
picture will be seen at this time.
(6) After interpolation, check convergence again and
repeat (1)-(5) if necessary.
(7) When convergence is acceptable, press PIP MODE
to write data to ROM memory. ROM WRITE? is
displayed to alarm system that ROM will be
overwritten with new data. Press the PIP MODE
button again to write displayed data to ROM.
(8) DATA WRITE TO ROM will take approximately 4
seconds and no picture will be displayed.
(9) Green dots will be displayed when operation is
completed.
(10) Press MUTE to return to convergence pattern, then
confirm again convergence is acceptable.
(11) Press PIP MODE (ROM WRITE) mode, then press
PIP CH to initialize sensor data positions.
Adjustment procedure
(12) Input any 1080I signal.
(13)Press EXIT key 5 times to exit video mode.
(14) Select an input with 1080i signal.
(15)Access menu and select ASPECT 5 mode.
(16)Press the SERVICE SW. ONLY button to enter to
DCU crosshatch signal.
(17)Repeat steps 2~11 above.
Notes: (1) Display only green for easier adjustment and
match to jig screen. Press “MENU”, THEN
PRESS “STATUS”.
(2) Perform interpolation and data write to ROM
after green adjustment. Once green has been
confirmed to match jig screen, the jig screen can
be removed. Do not readjust the green color
after jig screen has been removed. This is now
your reference color.
(3) Display green and red only and match red to
green.
(4) Display all colors and match blue to green and
red. Touch-up red color if necessary.
(5) Existing DATA in ROM can be read by pressing
the SWAP button 2 times. This data can be used
after replacing a component (CRT, DY, etc.)
Where complete convergence adjustment is not
necessary, be careful not to overwrite this data.
DO NOT write cleared RAM data into ROM or a
complete convergence adjustment will be
necessary. Remember to try MAGIC FOCUS
before starting convergence adjustment to
minimize adjustment time.
