Dual Automatic Temperature Control Module Self-Test The DATC module self-test will retrieve on-demand (hard fault) DTCs only, it will not retrieve continuous DTCs. Continuous DTCs can be cleared when exiting the DATC module self-test. Make sure to retrieve continuous DTCs by carrying out the Dual Automatic Temperature Control Module — Retrieve Continuous DTCs procedure before clearing any continuous DTCs.

• The DATC module self-test will not detect concerns associated with data link messages like engine coolant temperature or vehicle speed signals. A scan tool must be used to retrieve these concerns.
• The DATC module self-test will detect concerns in the system control functions and will display on-demand (hard fault) DTCs for concerns that are present during the self-test. The vehicle interior temperature should be between 4°C - 38°C (40°F - 100°F) when performing the self-test. If the temperatures are not within the specified ranges, false DTCs may be displayed.
• The self-test can be initiated after cycling the ignition switch from OFF to ON. Normal operation of the climate control system stops when the self-test is activated.
• To enter the self-test press the OFF and FLOOR buttons simultaneously and release, then press the AUTO button within two seconds. The display will show a flashing blower icon for 20 seconds, after which all vacuum fluorescent segments will be displayed if there are no on-demand DTCs present. If DTCs are present the DATC module will display "00 00" and then on-demand DTCs. Record all DTCs displayed.
• If any DTCs appear during the self-test, carry out the diagnostic procedure. Refer to the Dual Automatic Temperature Control Module Diagnostic Trouble Code Index and follow the ACTION for each DTC given.
• If a condition exists but no DTCs appear during the self-test, GO to Symptom Chart Condition: The DATC System Is Inoperative, Intermittent or Incorrect Operation.
• To exit the self-test and retain all continuous DTCs, press any button except DEFROST. The DATC module will exit the self-test and retain all continuous DTCs.
• To exit the self-test and clear all continuous DTCs, press the DEFROST button. The DATC module will exit the self-test and all continuous DTCs will be cleared.
• Always exit the self-test before powering the system down (system turned OFF). Once the self-test is exited the ignition switch must remain ON for at least 30 seconds to allow the temperature blend door actuators to automatically recalibrate.
• Continuous DTCs will be deleted after 80 ignition switch ON cycles after the intermittent fault occurs.

Dual Automatic Temperature Control Module — Retrieve Continuous DTCs The DATC module will retrieve only continuous (intermittent) DTCs when carrying out this procedure.

• Retrieval of continuous DTCs can be initiated after cycling the ignition switch from OFF to ON. Normal operation of the climate control system stops when retrieving continuous DTCs.
• To retrieve continuous DTCs press the OFF and PANEL buttons simultaneously and release, then press the AUTO button within two seconds. All vacuum fluorescent segments will be displayed if there are no continuous DTCs present. Continuous DTCs are indicated by the presence of the degrees Celsius symbol (°C) on the DATC module display. Record all DTCs displayed.
• If any DTCs appear, carry out the diagnostic procedure. Refer to the Dual Automatic Temperature Control Module Diagnostic Trouble Code Index and follow the ACTION for each DTC given.
• If a condition exists but no DTCs appear, GO to Symptom Chart Condition: The DATC System Is Inoperative, Intermittent or Incorrect Operation.
• To exit and retain all continuous DTCs, press any button except DEFROST. The DATC module will exit the retrieve continuous DTCs mode and retain all continuous DTCs.
• To exit and clear all continuous DTCs, press the DEFROST button. The DATC module will exit the retrieve continuous DTCs mode and all continuous DTCs will be cleared.
• Always exit the procedure before powering the system down (system turned OFF). Once the procedure is exited the ignition switch must remain ON for at least 30 seconds to allow the temperature blend door actuators to automatically recalibrate.
• Continuous DTCs will be deleted after 80 ignition switch ON cycles after the intermittent fault occurs.

Convergence is dead.Know how to solders?Must replaced the 2 convergence ICS and all it resistors.Tv Repair World.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop will cost u $300 for parts and labors.

This is like a quiz right?? Let's see ;;;;;;; by convergence resistors I assume you mean the yoke return resistors out in front of the amps. There are 6, in the 2.2ohm 1w range, easy enough to find. The value of the convergence amps, that unit uses two stk392-110 Sanyo original Ic's rated at 6amps. You can use stk392-150's or stk392-180's just a higher amp rating. The two pico fuses in that circuit are F851 and F852 respectively.
Hope I get an "A"

I had the same problem with the Toshiba 42H81 rear projection TV and the power supply circuit board had to be replaced.

you can replace these your self if you can solder and are mechanical. there are two stk ic attached to a silver heat shield

You can call or on line give them the model number and tell them you are looking for the convergence ics The part store .com

Be careful unplug if it looks to hard please call your local tv shop the fix for a shop is around 250.00

Thanks doctor video
