• Goes into safety mode for no apparent reason, after operating for 30 mins. Starts up again from the switch. (FF427 SABA repair tip)
• Blue fails - occasionally blue flyback lines visible.
• CTV blown, if connector BF01 remains connected. Vertical scanning line is at bottom of screen. (FF427 tips)
• Sound fizzles.
• Unstable vertical scanning with foldover in the picture. (part of circuit diagram displayed)
• Tube tries to switch on then switches off. (part of circuit diagram displayed)
• Part no info: PSU repair kit. (FF427 SABA repair tip)
• In playback, especially with prerecorded cassettes the picture oscillates horizontally or is distorted like a flag in the top part of the screen.
• Starts up with difficulty. Line transformer only starts up after several attempts.
• The picture is displaced towards the top of the screen (approx. 4cm to 10cm).
• TL19 (S2000AF) fails repeatedly.
• Blows on a white picture. Power supply as new. (FF427 SABA repair tip)
• Does not start up. Ok if power supply is 110V. Normal scanning.
• Part no. info: PSU repair kit.
• No picture. No sound. Insufficient width. Picture has a 5cm band at top of screen.
• CTV in standby one hour. After CTV does not start up from remote control or front panel. TV stops with the switch. Waits 30 mins. Starts to work again with switch. Functions ok with the remote control and front panel. (+ extract of circuit diagram)
• Blue picture, black and white perfect when the colour adjustment is set to zero. More and more blue when you increase the colour adjustment. Intermittent fault. (+ extract of circuit diagram)
• Chroma lacks green.
• Does not come on from standby, red standby light comes on. TV01 and TV02 in the protective circuit respond. (FF427 SABA repair tip)
• Vertical amplitude is too low.
• No TXT. (+ extract of circuit diagram)
• Audio hisses.
• Standby light switches off. (with circuit diagram extract)
• Picture is just at the top edge of the CRT if the vertical picture centering regulator is at the end position. The topmost lines are somewhat bent to the right.
• Picture is black/white. (part of circuit diagram displayed)
• Line transformer blows a few secs later after appliance is started up, line transformer has been changed but fault persists. Output voltage 8.2V instead of 15V on the power supply secondary with the line transformer removed.
• EHT starts. Line pulse then Stop. (+ extract of circuit diagram)
• Picture only in top part of screen. (picture attached) (service info for SABA -FF427)
• S2000AF blows each time appliance is plugged in. (with circuit diagram extract)
• OSD fades on all the colours.
• Blank raster.
• At start up, starts up then stops. Standby light remains lit.
• Sound sizzles.
• Part no. info: PSU repair kit.
• The appliance has a dark picture.
• Power supply pulsates intermittently when cold or warm.
• No raster signal on pin 31 of IV01. (FF427 tip from SABA)
• Switches to protection mode (after start-up). (part of circuit diagram displayed)
• Picture at the bottom. No contrast.
• Line in centre of picture.
• Channels scroll. Functions if control panel plate on front panel is disconnected.
• No colour. (picture attached)
• When set to standard adjustments the contrast value is too high.
• E/W correction can only be poorly adjusted. (with circuit diagram extract)
• The picture disappears, drifts then reappears for a few fractions of a second and then drifts again. A whistling noise can be heard when the picture reappears.
• Picture shows green, red and blue lines and the raster rattles audibly.
• Switches to standby. after a few seconds. (picture attached) (FF427 tip from SABA)
• Occasionally wide interference lines (similar to a defective HF-cable) appear on the screen. Picture is ok via Scart. (FF427 tip from SABA)
• Part no. info: PSU repair kit.
• Adjusting the peak white: chassis.
• Can not be switched on from standby via RC.
• Sound fizzles.
• PSU fails immediately after switch on.
• Picture pulling on bright scenes.
• No channels. Standby LED lit . (with circuit diagram extract)
• Trips erratically. (FF427 tips)
