VENUS X2 HDMI outboard 4K output issues

Overview

The source FAQ describes two board-level output faults on VENUS X2 HDMI output board hardware version V1.2. These are service-level hardware notes, not normal operator menu adjustments.

Applies to

VENUS X2 4HDMI output board V1.2

Symptom 1

Some 4K displays show no picture at 2048 x 1152 @ 60 Hz.

Source diagnosis

  • GENLOCK signal quality is not good.

Source remedy

  • Modify capacitor C360 to 10pF.
  • Leave resistor R482 as NC.
  • Modify resistor R508 to 0R.

Symptom 2

Some 4K monitors show no picture and report a resolution that does not match the configured output.

Source diagnosis

  • HS and VS signal quality is not good.

Source remedy

  • Modify resistors R484 and R485 from 0R to 100R.

Important note

  • These are hardware rework instructions tied specifically to V1.2 board revisions. Treat them as bench-service actions, not field UI troubleshooting.
  • Confirm board revision before applying any modification.
