* One common issue with the BVM-14F5U is that when the unit is turned on, the screen does not kick on and it instantly goes into OVERLOAD mode, and all three front lamps will flash. This appears to be a non-capacitor issue with the PA board, as swapping out this board seems to fix it. Often times you can work around this by plugging in the unit, pressing the standby button to turn the overload lights off, letting it sit for 20 minutes, then pressing the standby button again to power it on.

The F5 models are handy due to the fact that they do not require an external controller and instead provide buttons along the side of the unit to navigate the on-screen display. They also provide buttons for manual control over a handful of functions, including analog knobs for brightness, contrast, chroma, and phase.

Common Issues

  • One common issue with the BVM-14F5U is that when the unit is turned on, the screen does not kick on and it instantly goes into OVERLOAD mode, and all three front lamps will flash. This appears to be a non-capacitor issue with the PA board, as swapping out this board seems to fix it. Often times you can work around this by plugging in the unit, pressing the standby button to turn the overload lights off, letting it sit for 20 minutes, then pressing the standby button again to power it on.

Capacitors


Exclamation-triangle-fill.svgAlways replace capacitors with equal capacitance value and equal or greater voltage capacitors.
Higher temperature ratings (105°C instead of 80°C, etc.) are preferable and will extend the life of the capacitors.


Power Board (G)

  • Notes:
    • List assembled and verified by Derf. Your board may differ as C2-C5 and C9-C12 were not electrolytic as the manual stated in the below case.
    • D4 is an extra electrolytic cap that was found in place of D4; negative terminal closer to C16.
    • The list below does not include power sub-boards GA, GB, or GC.
