54306901 SCHAUBLORENZ6868F / SCHAUBLORENZ [TV 70-74 (66-70) cm picture]

• Colour appears in horizontal stripes. In some bars colour OK, in others no colour.
• Shaky picture at switch on. Picture OK after 5 mins.
• Vertical deflection incorrect. Approx. 10cm black stripe at upper picture edge.
• Line tearing. Lines are not synchronised intermittently.
• No colour. intermittently.
• Dark horizontal stripes in picture, which become stronger after warm-up.
• Vertical jitter.
• Stripes in picture.
• Faulty VCR playback.
• Starts up ok. After 5 mins power supply collapses, minimum picture format, white screen. (SCHAUBLORENZ - 54306901 information)
• No picture.
• Power supply goes defective after a few days.
• Vertical jitter and hum in the picture, only in VHF range. (with circuit diagram extract)
• Does not recognise transmissions in SECAM. Functions well in PAL. Connected to a SECAM VCR via scart socket, cassettes are read correctly.
• Stuck in standby.
• No TXT.
• No tuning.
• Picture is darker on left side than on the right.
• No NICAM sound. FM sound buzzes.
• Resistors R503 and R506 fail.
• Narrow stripes approx. 1 cm. (service info for SCHAUBLORENZ -54306901)
• Switches to BG from NICAM.
• No vertical deflection. intermittently.
• Fine lines move from bottom to top of screen.
• Poor sync, no or unstable sound plus hum bars.
• PSU chirps after switch on and appliance does not start.
• No picture content. Blurred picture and folds over on top.
• Horizontal tearing. at top.
• Dead.
• On channel 25 remains in low range, HF IF head has been changed.
• Stuck in BG norm.
• Horizontal jitter.
• Venetian blind effect runs through from bottom to top. No reaction to freezer.
• Occasionally goes into BG standard especially on first channel. Remains in BG standard if channel is not switched over a few times.
• Line tearing and the top 5 cm of the picture is folded over; unclear picture in general. When warming up tuner with hot air picture becomes normal.
• Poor vertical synchronisation. when cold.
• Horizontal collapse.
• Enter service mode.
• All channels ok except 1. Unstable picture as if sync problem then goes into PAL.
• Squealing from PSU. when cold.
• Whistling. at start-up. Horizontal line. after a while. (SCHAUBLORENZ - 54306901 information)
• Line transformer whistling. Line BU has been changed without any effect. Still the same when you lift the BU collector, 150V otherwise voltage decreases to 40V.
• No picture. when cold.
• Picture gets darker after approx 3-4 mins (a faint picture remains). Beam current is very low.
• For a short time after switching on the line foldover and picture is distorted.
• Thin black lines at bottom of raster.
• Line tearing in the first few minutes after switch on. No reaction to freezer spray. (with circuit diagram extract)
• Crackling audio. intermittently.
• No sound by mono transmissions or too low. OK in STEREO.
• Crackling audio. at switch-off.
• Flyback lines. on upper half screen. (54306901 tips)
• No reception.
• After switching from band 1 or 4 to band 3 there is no reception from band 3. Absolutely no reception on band 3 after a short period.
• Picture is dark and only black and white. No colour in SECAM or PAL. Flyback raster visible as well as TXT lines.
• Black smears on the variable picture.
• Will not switch on, PSU trips briefly, then protective switching is active.
• No audio.
• Horizontal smearing. Split image.
• PSU transistor 508A fails.
• When TV started up, transistor (S2000AF) instantly burn out.
• Procedure to lock TV in standard L.
• No picture. No sound. When switched on via power switch functions accidentally.
• Horizontal and vertical unstable, mostly when cold.
• Thin horizontal stripes in picture in EE mode.
• PSU does not start up (appliance may load with a light bulb). (part of circuit diagram displayed)
• Switches to protection mode.
• When switched on, the appliance attempts to start up but fails.
• Loud popping. Picture size varies.
• Nasal sound in the tuner. Scart functions correctly.
• Tries to start at switch on but picture only appears briefly.
• Excessive high voltage. Line stage sparks on video amplifier board.
• No functions.
• No band 3 after switch over.
• Problem to receive channels 5 and 6 (channel 53 and 65).
• Vertical collapse.
• No sound. Amplifier ok.
• Vertical stripe intermittently.
• Line chirps.
• Raster is blank and picture is missing.
• Drum motor hunts or runs fast.
• No picture. Audio OK .
• No tuning. Higher channels in band I/III/V are not received. (54306901 tips)
• Darker image at right side, become lighter on left side.
• When switching off with the RCU a horizontal line remains on the screen.
• Horizontal foldover. (with circuit diagram extract)
• No or poor synchronisation. Poor audio. when cold.
• At high frequency areas the station goes out of tune (ie SAT1, channel 58).
• CTV switches to PAL mode on channel 25 (TF1), no matter which channel has been selected. No problems on channels 22, 28, 30 and 33.
• No start-up. Protection mode activated.
• Line output transistor fails at start-up.
• Picture shifted horizontally. (54306901 SCHAUBLORENZ repair tip)
• Trips instantaneously.
• No sound and a blank raster, the channel display shows rubbish and appliance doesn't respond to remote control commands.
• No signal and frame collapse. (54306901 tip from SCHAUBLORENZ)
• At switch on the standby LED comes on then switches off after one sec. The power supply does not start up. S2000 power supply is ok, scanning is ok.
• Picture has horizontally reduced by 2cm.
• Sound is low and distorted in AM.
