1764LR / VANDA [17" monitors]

• Dead.
• No display. Appliance starts. If the picture appears, all geometry values are incorrect.
• No green.
• Code number correction: resistor 3377.
• Horizontal phase twitches. (1764LR VANDA repair tip)
• B+ supply voltage setting adjustment.
• Horizontal transistor TR7510 (LJH16212) and E/W output stage transistor TR7519 (BU406) fail.
• Picture only ok in the top part, the rest has no contrast.
• Power does not start up in cold conditions.
• Blank raster.
• Vertical deflection is defective.
• No horizontal synchronisation.
• No vertical deflection.
• Verticals oscillate.
• PSU does not work.
• T7519 fails at the moment of switch on. PSU whistles.
• Input and terminal panel adjustment.
• Video panel repair instructions. (1764LR VANDA repair tip)
• White D setting.
• Distorted picture.
• Sub-contrast using photometer 1 adjustment.
• No horizontal deflection.
• Will not power up in cold conditions.
• S/C at both output stages.
• Deflection and supply panel repair instructions.
• Picture width lowers and E/W fault. Knock sensitive.
• LCD contrast adjustment.
• Spare part information: horizontal output transistor LJH16212.
• Cut-off points of picture tube.
• No horizontal convergence - not adjustable.
• Picture geometry setting adjustment. (service info for VANDA -1764LR)
• Too bright with flyback lines and vertical fault (Foldover because voltage collapses).
• Vertical synchronisation fails after warming up.
• Dead, (7510 and 7519 defective).
• PSU whistles rhythmically.
• Picture is slightly wider at the right side than in the centre. Greater at high resolutions. (1764LR VANDA repair tip)
• Horizontal synchronisation setting adjustment.
• Sub-contrast using photometer adjustment.
• No HV.
• No functions.
• Occasionally horizontal centering.
• Dead at switch on (only when mains voltage is < 180V). (1764LR VANDA repair tip)
• No vertical synchronisation.
• No picture - intermittent, or no picture at all.
• No blue.
• HV EHT setting adjustment.
• Picture noisy when using applications with low sync. freq.
• Picture out of focus.
• Brightness cannot be adjusted.
• No brightness control.
• Dead after replacing TDA4800/V2- 4822 209 32242.
• Letters wider at both sides than in the middle in Windows 1024x768/75Hz. Ok in DOS.
• B+ supply voltage adjustment. (1764LR tip from VANDA)
• Poor pincushion.
• No display.
• No function, PSU ticks softly.
• No function.
• Dead (7606 and 7608 defective).
• Horizontal sync adjustment.
• Cut-off points adjustment.
