• Improving the reliability of TP24 (S2000 or BU508). (with circuit diagram extract)
• Switches to standby (after a few seconds). (extract of circuit diagram attached)
• No TXT (intermittently). (service info for SABA -FF470)
• TP24 gets hot and short circuits. Poor base command.
• Vertical lines run over the whole screen. (extract of circuit diagram attached)
• Poor focus on picture or TXT. Low brightness and badly smeared. (with circuit diagram extract)
• Crackling audio. Snow in picture. (extract of circuit diagram attached)
• No audio. (with circuit diagram extract)
• No functions. (picture attached)
• Trips after warming up for a few minutes. (+ extract of circuit diagram)
• Voltage U5 21V goes to 35V when appliance is warm. Vertical displacement. The other EHT secondary voltages are stable.
• LED display characters are back to front. (part of circuit diagram displayed)
• Intermittently blocks in AV. The channels remain displayed on the display. (FF470 tip from SABA)
• S2000 in power supply defective after a few mins.
• Intermittent OSG display and sound is reduced. (picture attached)
• No stereo reception on channel 60.
• Crackling on Nicam.
• No channel storing.
• No STEREO reception on channel 60.
• Child lock.
• Shuts down.
• Tuning drifts (after a while). (SABA - FF470 information)
• No picture only on 3 channels (eg. nothing on 1, 3 and 6 but picture on 2 and 5) after warming up for 10 mins. This problem disturbs other TVs plugged into the same aerial. (+ extract of circuit diagram)
• Intermittently goes into TXT mode. (with circuit diagram extract)
• Excessive HV.
• No tuning possible. Hum in VHF. Channel display correct.
• When cold trips 3 times with crackling in the speaker, then safety mode. When warm trips then starts up. (part of circuit diagram displayed)
• No audio.
• No picture (after a few minutes).
• Ticking noise on sound and intermittent sound mute. (FF470 SABA repair tip)
• The picture moves out of its frame when the appliance is warm.
• Service info: Contrast- and beam current adjustment after replacing chroma video module.
• Intermittently noise breaks through on NICAM sound.
• Replaced small transformer which was burning but TV remains in standby and FBT crackles for 5-6 secs then nothing.
• Very faint and bright picture via tuner. Picture ok via scart via a VCR.
• The power supply blocks. (FF470 tips)
• Brightness varies until there is a dark picture.
• After a storm no sound and no picture. No light, filament lights up, line transformer ok. screen remains dark, light appears at switch off.
• The PSU switches 3 times, line transformer, E/W diodes, U4 and U5 are ok. (FF470 tip from SABA)
• Mains switch does not lock on.
• Intermittent dead. Can be OK for days. (part of circuit diagram displayed)
• Audible whistling from the back of the cabinet.
• Power supply transistor blows up at switch on. (part of circuit diagram displayed)
• Colour bleeding.
• Picture geometry problems.
• Poor chrominance of black/white with colour at zero.
• No picture. There is a white raster on the right of the screen.
• Line output transistor S/C. (picture attached) (SABA - FF470 information)
• Rolling coloured and white lines. (extract of circuit diagram attached)
• Intermittent crackle on sound.
• Intermittent audio.
• Colour drop-out.
• Frame jumping or twitching. (part of circuit diagram displayed)
• Partial blanking of video info. (picture attached)
• No picture. A flyback is apparent when you increase the G2. (with circuit diagram extract)
• TL29 fails in B and C after start up.
• OSD only functions in PAL.
• Sound pops.
• Line tearing in TXT. (service info for SABA -FF470)
• Bright picture. Flyback lines.
• Occasionally colour fails.
• Shade gradually becomes purplish. Ok at start up. Degaussing ok.
• No focus. (part of circuit diagram displayed)
