TM4217ONLD / TARGA [Monitors]

• Insufficient pincushion control.
• E/W fault (pincushion). No E/W- and trapezium regulation.
• Video RGB colour problem.
• No picture. No high voltage.
• Vertical collapse.
• No vertical deflection, no vertical sync from processor board.
• PSU switches to protective circuit.
• Convergence error.
• Power supply problem.
• Voltages measured.
• No function. Width is only approx. 2/3, but can be adjusted.
• Focus and convergence adjustment.
• No picture.
• After switch on enter protective circuit after a short time. (service info for TARGA -TM4217ONLD)
• No picture. LED flickers.
• Picture width is only approx. 2/3 of the picture and cannot be adjusted.
• Excessive horizontal size.
• Reduced horizontal size.
• No brightness adjustment from front control panel.
• Horizontal stage starts up for a short time. Mains voltages ok.
• Picture is dark, vertical stage oscillates irregularly.
• Excessive brightness. Retrace lines.
• Occasionally E/W adjustment and line linearity changes.
• Picture fails after approx. 1 min and monitor switches off.
• Dead.
• Raster white balance adjustment.
• Value for ZD303 in the PSU.
