• The picture goes wrong all the time in the vertical direction. A black band appears at the bottom. The capacitors at the level of the raster IC are ok. Solder joints have been redone.
• Sound distorted when volume increased.
• Poor grey scale. Dominates in black and white. (extract of circuit diagram attached)
• Only rainbow effect (picture foldover).
• Weak blue until the brightness is turned up, but then blue flares. (+ extract of circuit diagram)
• Spitting noise from speaker. Intermittent digital sound. NICAM LED's go out.
• The picture moves out of its frame when the appliance is warm.
• TV functions but the displays are erased after a few secs.
• Mains transistor TP24 (S2000AF) blown straight after being turned on.
• Colour cuts out occasionally.
• Picture is split in two like an aerial echo on all channels even on cable channels.
• No audio.
• Tuner cutting out occasionally. (SABA - FF503 information)
• PSU starts up 1 time out of 10. At switch off, green dot lights up and then goes out.
• No switch on. When switching off with mains switch LED switches on then off.
• Power supply shuts down. Line drive pulls HT down.
• Sporadic hum from speaker. Hum disappears when switched off and on. (with circuit diagram extract)
• In time picture increasingly wanders down the screen.
• Popping noise at switch on. (Nicam model).
• The channel frequency shifts for 3 seconds then shifts again. (+ extract of circuit diagram)
• No high voltage or line signal control. (with circuit diagram extract)
• Cables to be connected on the vertical deflector.
• No sound or picture. Dark screen. FBT functions. Filament tube is lit up. In scart with a VCR normal sound but no picture. Raster appears faintly when the TV is switched off then switched on again immediately.
• Relaxation of the power supply. If point 8 of the THT is opened, the 110V voltage returns. (extract of circuit diagram attached)
• Slight picture jitter in the vertical synchronisation. (extract of circuit diagram attached)
• Pincushion distortion. (extract of circuit diagram attached)
• Failure of LG11 in line output circuit. (with circuit diagram extract)
• Stuck in standby. (with circuit diagram extract)
• Terrestrial channel in the background of a satellite transmission.
• Red raster. Flyback lines. (part of circuit diagram displayed)
• AGC problems. Poor reception. (with circuit diagram extract)
• No colour in Secam, ok in Pal. RGB ok. (FF503 SABA repair tip)
• Variable sound and picture crackling with snow.
• Only rainbow colours (picture foldover).
• After switch on power supply pulsates three times. (part of circuit diagram displayed)
• Trips after 15-20 mins. (+ extract of circuit diagram)
• Loss of memory. All program sites on C00.
• No video signal. Sound and TXT display OK.
• Power supply BU blows after operating for a short time. (part of circuit diagram displayed)
• Intermittently noise breaks through on NICAM sound.
• Loud noises from speaker (at switch-off).
• No line oscillation. (extract of circuit diagram attached)
• Part number info: processors (FF503 tips)
• Occasionally there is a luminance problem when warm. (extract of circuit diagram attached) (FF503 tip from SABA)
• Set blocks (operation via RC or via user control only possible, after the set has been switched off and on again by mains switch.
• Picture is green, red or blue with flyback lines. (with circuit diagram extract)
• Vertical collapse. at top.
• No audio.
• Spare part no. info: Power supply repair kit.
• Occasionally no start up. Protective circuit sets in. No soft start. (with circuit diagram extract)
• Accepts channel number but will not tune.
• Appliance has no HF reception. Snowy picture. (FF503 tips)
• PSU fails in various conditions.
• At switch on, after 15 secs, dark screen with a few horizontal white lines between the middle and top of screen. Picture returns with geometry fault, if PG08 is turned. Sound ok.
