54332961 SCHAUBLORENZ8868 / SCHAUBLORENZ [TV 70-74 (66-70) cm picture]

• Whistling. at start-up. Horizontal line. after a while.
• No picture. when cold.
• When TV started up, transistor (S2000AF) instantly burn out.
• No picture content. Blurred picture and folds over on top.
• Switches to protection mode. (54332961 SCHAUBLORENZ repair tip)
• Tries to start at switch on but picture only appears briefly.
• Vertical deflection incorrect. Approx. 10cm black stripe at upper picture edge.
• Horizontal smearing. Split image.
• Line tearing. Lines are not synchronised intermittently.
• At high frequency areas the station goes out of tune (ie SAT1, channel 58).
• Picture is dark and only black and white. No colour in SECAM or PAL. Flyback raster visible as well as TXT lines.
• No vertical deflection. intermittently. (service info for SCHAUBLORENZ -54332961)
• Enter service mode.
• No sound and a blank raster, the channel display shows rubbish and appliance doesn't respond to remote control commands.
• PSU transistor 508A fails.
• No picture. No sound. When switched on via power switch functions accidentally.
• Line chirps.
• Squealing from PSU. when cold.
• For a short time after switching on the line foldover and picture is distorted.
• 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.
• PSU does not start up (appliance may load with a light bulb). (extract of circuit diagram attached)
• Black smears on the variable picture.
• All channels ok except 1. Unstable picture as if sync problem then goes into PAL.
• Dead.
• Shaky picture at switch on. Picture OK after 5 mins.
• Poor sync, no or unstable sound plus hum bars.
• Vertical collapse.
• Stripes in picture.
• No tuning. Higher channels in band I/III/V are not received.
• Horizontal collapse.
• No functions.
• 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.
• Raster is blank and picture is missing.
• Stuck in standby.
• Darker image at right side, become lighter on left side. (54332961 SCHAUBLORENZ repair tip)
• Picture has horizontally reduced by 2cm.
• No band 3 after switch over.
• Poor vertical synchronisation. when cold. (54332961 tip from SCHAUBLORENZ)
• Picture shifted horizontally.
• Faulty VCR playback.
• Narrow stripes approx. 1 cm.
• When switched on, the appliance attempts to start up but fails.
• Switches to BG from NICAM.
• No TXT.
• Drum motor hunts or runs fast.
• No start-up. Protection mode activated.
• Line tearing in the first few minutes after switch on. No reaction to freezer spray. (part of circuit diagram displayed)
• Resistors R503 and R506 fail.
• On channel 25 remains in low range, HF IF head has been changed.
• No picture. Audio OK .
• Vertical jitter.
• Starts up ok. After 5 mins power supply collapses, minimum picture format, white screen.
• Horizontal tearing. at top.
• Colour appears in horizontal stripes. In some bars colour OK, in others no colour.
• Does not recognise transmissions in SECAM. Functions well in PAL. Connected to a SECAM VCR via scart socket, cassettes are read correctly. (54332961 SCHAUBLORENZ repair tip)
• Horizontal and vertical unstable, mostly when cold.
• Problem to receive channels 5 and 6 (channel 53 and 65).
• Occasionally goes into BG standard especially on first channel. Remains in BG standard if channel is not switched over a few times.
• Horizontal foldover. (+ extract of circuit diagram)
• 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.
• Vertical jitter and hum in the picture, only in VHF range. (with circuit diagram extract)
• Loud popping. Picture size varies.
• Dark horizontal stripes in picture, which become stronger after warm-up.
• No tuning. (SCHAUBLORENZ - 54332961 information)
• Excessive high voltage. Line stage sparks on video amplifier board.
• No picture.
• Thin black lines at bottom of raster.
• Line output transistor fails at start-up.
• Vertical stripe intermittently. (service info for SCHAUBLORENZ -54332961)
• 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. (service info for SCHAUBLORENZ -54332961)
• No signal and frame collapse.
• No audio.
• PSU chirps after switch on and appliance does not start.
• Trips instantaneously.
• Picture is darker on left side than on the right.
• Crackling audio. intermittently.
• No sound by mono transmissions or too low. OK in STEREO. (54332961 tips)
• Fine lines move from bottom to top of screen.
• Horizontal jitter.
• No or poor synchronisation. Poor audio. when cold.
• Power supply goes defective after a few days.
• Thin horizontal stripes in picture in EE mode. (54332961 SCHAUBLORENZ repair tip)
• Crackling audio. at switch-off.
• No reception.
• Venetian blind effect runs through from bottom to top. No reaction to freezer.
• Picture gets darker after approx 3-4 mins (a faint picture remains). Beam current is very low.
• When switching off with the RCU a horizontal line remains on the screen.
• 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.
• Flyback lines. on upper half screen.
• No NICAM sound. FM sound buzzes. (service info for SCHAUBLORENZ -54332961)
• Will not switch on, PSU trips briefly, then protective switching is active. (54332961 tip from SCHAUBLORENZ)
