• Pulsing/rolling on high brightness.
• LEDs are not lit or only partially lit.
• Picture rolling. Hold control has no effect. (service info for ICS -CTV2024AV)
• Dead. Whines at switch on.
• Set switches off when attempting to tune in.
• Teletext handsets batteries not lasting very long.
• Fine ragged verticals. (CTV2024AV tips)
• EHT flashover. (CTV2024AV ICS repair tip)
• Field rolling.
• Very bright red picture.
• The appliance is dead, BU426 nad BU500 are short circuit, TDA4600 U/S-22nF is leaky.
• Dead.
• Low power supply output.
• Approx 10 mins after switch on sound and vision suddenly disappear.
• Excessive brightness.
• Blank raster. Sound OK.
• Appliance remains on channel 1.
• No field hold.
• TR5 (BU508) S/C.
• Set suffered from field jitter. It would sometimes start at switch on and continue until the set was switched off. At other times the display would be ok for about an hour, then the fault would appear.
• Intermittent manual programme change.
• RCU or channel change do not function.
• Insufficient picture width and CRT is weak. When adjusting brightness or contrast, station tuning is lost.
• Full brightness with flyback lines.
• Green cast on screen.
• Ringing on verticals.

• Picture predominantly green/pink with occasional surges of green saturation. (service info for ICS -CTV2024AV)
• Blank raster with flyback lines.
• Blank raster.
• Severe line tearing and noises coming from the set.
• Very little contrast. The on screen display gave a normal indication.
• Low brightness or no picture.
• Field collapse
• Excessive red. (ICS - CTV2024AV information)
