• Production mode.
• Blue fails - occasionally blue flyback lines visible.
• No picture. Audio OK .
• Line frequency drifts slightly.
• All the secondary voltages are low.
• Line does not oscillate. (3135 tips)
• White screen. Audio OK .
• Horizontal collapse. (with circuit diagram extract) (3135 tip from GEC)
• TV01 and TV02 are in safety mode.
• Intermittent switches to standby during programme or scene change. (picture attached)
• Red picture. Flyback lines.
• When the focus pot is varied the brightness varies after a few minutes, the picture turns dark.
• Occasionally static discharge.
• No raster signal on pin 31 of IV01.
• Picture rolls. (picture attached)
• Switches to protection mode. (extract of circuit diagram attached)
• Pale grey screen with fine horizontal line and hum at start up of the line transformer. (picture attached)
• Picture is OK although raster has moved up. (with circuit diagram extract)
• Channels run through, sound whistles and there are lines if picture present.
• The appliance goes to secondary safety mode. (extract of circuit diagram attached)
• Blank raster.
• Menu display is in a wrong language.
• Does not change channels.
• Vertical line wavering at left hand side. (+ extract of circuit diagram)
• Hum on sound and dark screen. Goes into standby.
• Compressed vertical. Extremely dark picture, more on the right than on the left.
• Blows fuses.
• Twinning lines at top. Vertical distorted. Becomes better after warmed up.
• When playing back a cassette previously recorded by the same VCR, colours may be lost or blue flash interference due to the PAL pulse of the TV being triggered.
• Power supply transistor S2000AF blows after operating for one hour. (extract of circuit diagram attached)
• Switches off by itself. at start-up (when cold).
• Standby light switches off. (part of circuit diagram displayed)
