CPS1760LR / OKANO [Monitors]

• Intermittent vertical foldover.
• Q401 repeat failure in 15 min.
• Vertical collapse. (service info for OKANO -CPS1760LR)
• Horizontal linearity off. Letters outside of screen smaller than centre.
• Width excessive.Q305 shorted, C308 puffy, D410 burned.
• Dead. Power LED blinks 2-3 times.
• No horizontal linearity.
• Voltages at IC305 (LA7856).
• Zd401, 402 & 403 info
• Picture gets brighter when warming up.
• Vertical line.
• No horizontal deflection.
• No function - PSU ticks.
• Tearing of the vertical lines (line tearing) and noise in the monitor are dependent on the picture content. With a grey level very visible in the top third of the picture, comparable with hum distortion.
• Main PCB rebuild. (CPS1760LR tip from OKANO)
• Arcing.
• Video is poor. (CPS1760LR OKANO repair tip)
• Too wide, pincushion error particularly after horizontal output transistor fails. (CPS1760LR tip from OKANO)
• Q401 repeatedly fails within 15 mins.
• Vertical lines have convergence fault and picture shakes briefly esp. when appliance is cold.
• Horizontals problems.
• Horizontal linearity off. Letters outsides of screen smaller than centre.
• No horizontal size adjustment. Screen is barrelled at sides, squeezed in centre.
• SMPS rebuild.
• Vertical Quiver or flutter at low freq
• Power up intermittent. PS voltages about 2/3 of value
• Q305 repeatedly fails.
• Shuts down.
• After power-up 4 clicks from PSU then shutsdown.
• Video very slow to appear.
• No function - fuse F101 S/C.
• No picture.
• Intermittently vertical jumps at low vertical scan rates.
• Width control inoperative. Narrow pincushion.
• Vertical defective.
• Horizontal linearity fault.
• CRT PCB rebuild.
• No vertical deflection (intermittently). (service info for OKANO -CPS1760LR)
• Excessive horizontal size.
• Occasionally picture collapses.
• Fuse (2.5A AC) blows at once when powered up.
• High voltage arcing.
• Black screen.
• After switch on line in picture for 1 min.
• No HV.
• Specifications.
• Q305 repeat failure
• Dead.
• PSU fails again.
• Voltages at plugs P106 and P102.
• Vertical jitter or flutter at low frequency.
• Screen too narrow.
• Red vertical bar on right side of screen, video present.
• Horizontal linearity off.
• Unstable sync with ragged edges. (service info for OKANO -CPS1760LR)
• AD401, ZD402 and ZD403 info.
• Temporarily picture is compressed 10cm at the top and at the bottom it folds over approx 10mm.
• Screen is wavy.
• Excessive width which cannot be adjusted. (CPS1760LR OKANO repair tip)
• Dead, no 25V, F101 O/C.
• Dead. Q305 (2SD336A), D410 (UF5404) and C306 blown.
• No control of horizontal width - pincushion.
• Reduced vertical size.
• Colour problems. (service info for OKANO -CPS1760LR)
• Intermittent power up. Power supply voltages approx 2/3 value.
• Width control inoperative. Poor pincushion.
