TECHNICAL INFORMATION
Colour Television
Model:- All 100Hz Models

Chassis:- All above models displaying phenomenon described.

Date:- 23/11/01

Subject: Vertical Bands.

Please use the following IRIS codes when making a claim:-
1.Symptom = F343 2. Section Code = 0UT
3.Defect Code = T 4. Repair Code = K

Background: The reported Models (TX32PK25/28PK25) AND DVD players (SC-HT80 / SC-HT70)
