CTV28100ST APK000 / ITT [TV 70-74 (66-70) cm picture]

• Picture is only visible in the top fourth.
• Picture too small and slight pumping according to picture content.
• Standby OK, pumps with a whistle after switch on.
• Switches off by itself. LED blinks .
• Two vertical stripes on the left and right sides by bright picture via scart. (CTV28100ST tips)
• Slow start-up.
• How to reprogramm the appliance so thet it can be switched on via he mains switch without going via standby. (CTV28100ST tip from ITT)
• Bright picture. Flyback lines. Shuts down. after a few seconds.
• Picture becomes bright. Flyback stripes, then protective circuit switches on. (service info for ITT -CTV28100ST)
• Switches to protection mode.
• Red LED is lit. LED switches off briefly when trying to start via RC, slight oscillation audible, then LED red again.
• Picture size changes with beam current and slight E/W distortion.
• E/W fault. Picture too large with slight bowing, format switching ok.
• Switching transistor S/C between collector and emitter, after 3 secs. (ITT - CTV28100ST information)
• No picture via AV1, ok via tuner and AV2.
• Noises from PSU.
• No vertical deflection.
• Switches off after 10 sec. Standby LED flashes 3 times, 3 sek. pause, then LED flashes again 3 times.
• Picture folded over at the top. Bright lines in the picture.
• Line output stage transistor (2SC5331) and R536 (6R8/1W) are defective. (service info for ITT -CTV28100ST)
• No picture. Audio OK . (service info for ITT -CTV28100ST)
• E/W fault.
• Horizontal output transistor fails repeatedly.
• Oscialltes at start up briefly, switches then immediately off.
• Clock display runs erratically in standby.
• PSU bleeps. (CTV28100ST tip from ITT)
• Line output stage transistor fails immediately after switch on.
• Enter service mode.
• Black screen. after a few minutes. Audio OK .
• No functions. PSU pulsates.

• No picture content / blue picture. Display and TXT present. When Blue Picture option in the MENU is OFF, then the picture is white. (service info for ITT -CTV28100ST)
• Reduced horizontal deflection. Reduced vertical deflection.
• Reduced horizontal amplitude after switch-on for approx. 5-8 secs., with slight E/W effect, then horizontal amplitude jumps to the right value. (ITT - CTV28100ST information)
• Audio rattles.
• Protection mode activated.
• Picture is too large, there is no contrast.
• No RC functions.
• Switches to standby. after a few seconds. Standby LED flashes .

• No function. All LED pump.
• Line transistor fails after two days.
• Dead. (ITT - CTV28100ST information)
• Excessive horizontal size. No E/W correction.
• Picture too bright. Menu can be called up, picture content cannot be recognised.
• E/W error, picture too wide, format switching does not function.
