f the instrument will not turn on but the standby supplies are functioning, then it is possible to
read the error codes stored in the main EEPROM by using the “Dead Set” procedure.
Procedure:
Chassis Communications (TECI1) Switch Position
The switch on the TECI1 adapter needs to be in the correct position to communicate with the
chassis. The other position is for convergence communication. To put the switch in the
correct position, locate the three (3) pin connector next to the switch. Slide the switch to the
position closest to the 3-pin connector. This is the correct position for chassis communication.
NOTE: The switch can be located on the top or the bottom of the adapter.
1. Apply power to the Chipper Check box. Connect the interface box to the PC and start
Chipper Check software.
2. Select the TECI1 adapter and connect it to the Chipper Check interface box.
3. Select the correct adapter cable for the television you will be communicating with and
plug it into the TECI1 adapter:
ATC221 use the 7 to 4 pin connector cable.
ITC222 uses the 7 to 10 pin connector cable.
4. Plug the adapter cable into the television. The connector is located on the AV panel
and is accessible without removing the back cover on the ITC222 and ATC221.
5. Communication is established when the customer information screen appears on the
PC screen (Chipper Check software).
EEPROM and Diagnostics are the only tabs that Chipper Check can perform on these chassis.
Alignments are done manually using a remote or the FPA buttons. See the appropriate
service data for the alignment procedures.
Dead Set
By selecting the ‘Dead Set” button on the start screen of Chipper Check, brings up the chassis
selection screen. Select the chassis being serviced and follow the instructions on the Chipper
Check software screen.
