• Stuck in standby when switched off into standby using RC.
• Vertical collapse. (part of circuit diagram displayed)
• Service info: Function of the E/W stage.
• No picture, only faint coloured areas. (with circuit diagram extract)
• CTV loses its programming when there is a power cut. What is the value the battery must charge at ?
• Channel 60 and special channels flicker. U6 (30V) is too low.
• Wavy picture on right side. Switches off after 5 to 10 mins. (extract of circuit diagram attached)
• Intermittent loss of colour while setting up picture geometry.
• No audio.
• Occasional raster desynchronisation.
• No or intermittent picture. via RF output. OK via SCART . (part of circuit diagram displayed)
• Disable electronic lock.
• Menu display in wrong language.
• Ticking noise on sound with intermittent mute.
• No functions. (picture attached) (FF451 tips)
• Red raster. Flyback lines. (part of circuit diagram displayed)
• No LL' switching when you press C of the remote control.
• Reduced vertical deflection.
• Switches off for a short time then returns on programme 1 (early F15 chassis). (FF451 tips)
• Only the green LED on.
• Dark picture. Poor adjustment of sound. (part of circuit diagram displayed)
• No off-air luma. TXT OK.
• Distortion in the south. Distortion starting at both sides and going to a third of the tube. Fault in the shape of a curve whose extremities are the corners of the tube. (part of circuit diagram displayed)
• No picture at switch-on. Sound OK. Picture may return intermittently. (part of circuit diagram displayed) (FF451 SABA repair tip)
• Crackling on Nicam.
• At switch on, focus pot arcing and igniting. CRT board and tube ventiduct disconnected but fault persists.
• Sound pulsing off and on Nicam lights flashing.
• There is 145V instead of 170V and there is too much L/T amplitude.
• Blurred picture, fine adjustment does not adjust sufficiently.
• The sound disappears when the appliance is warm.
• Crackling audio. Snow in picture. (+ extract of circuit diagram) (FF451 tip from SABA)
• Picture jumps and vertical distorsion according to video content, mostly on second station, channel 21. Intermittent fault.
• Picture interference at the top and bottom, which changes with the line amplitude. (picture attached)
• The picture moves out of its frame when the appliance is warm.
• PSU trips 3 times then shuts down. (picture attached)
• Poor audio.
• The 1.6A fuse is open circuit. (+ extract of circuit diagram)
• Occasionally memorized data of control unit processor is lost at switch on or switch off with mains switch.
• No high voltage or line signal control. (picture attached)
• Picture jitters.
• Will not go into standby cleanly when hot, it will pulse between standby and on 5/6 times before finally staying in standby.
• Audible whistling from the back of the cabinet.
• Power supply goes into safety mode. (+ extract of circuit diagram)
• No text, sound muted. (picture attached)
• TP24 is destroyed, following a circuit break and return to programme 1. (with circuit diagram extract)
• Colour bleeding.
• Top half picture blank, bottom half bright flyback lines.
