Check F231 and resolder flyback pins.
Also: from Thomson Service Bulletin:
DATE: 12/8/2006
Chassis: ITC222
TOPIC: Ribbon Connectors, Intermittent faults
Symptom: Intermittent shutdown, Error Code 33, Convergence Errors, Miscellaneous Faults
Cause: Deformed Ribbon Connectors
Cure: Replace Connector - RCA Stock #258686
In ITC222 based TVs manufactured between serial number range G13XXXXXX and G26XXXXXX, Power Supply
Deflection connector, BP005 (Figure 1), and Convergence Module connector, BW005, have been found deformed.
The deformity results in inadequate pressure applied to various contacts of the inserted ribbon cable. Depending on
the contacts involved, this defect will result in random faults such as intermittent shutdowns, Error Code 33,
convergence issues, dead set, etc.
Although there is a possibility of deformed connectors in other LOT codes, Power Supply Deflection modules marked
with LOT # NNA600020A and Convergence Modules marked with LOT # NNA600011B are highly suspect. The LOT
number may be found on a white sticker just above the barcode label on each module. (Figure 2)
