What the Service Includes

The service covers full power board diagnostics (input filter, PFC, primary/secondary converters, 5V/12V/24V rails, 5VSB standby, CCFL inverter or LED driver), replacement of faulty parts, and comprehensive verification. We replace swollen/leaking capacitors with low-ESR equivalents, power MOSFETs, PWM ICs, optocouplers, diode bridges. Checks transformers, inductors, protection circuits. Compatible with TV repair due to similar power topologies.

When the Service is Needed

Power circuit repair is required when the monitor won't power on, indicator blinks, screen turns off after seconds, backlight fails, no response to buttons, high-pitched whine, or burning smell occurs. Causes include capacitor aging (3–8 years), power surges, dust/overheating, or LED string short. If indicator lights but screen stays dark, or voltages are missing on connectors — the issue lies in the power circuits.

Work Stages

  • Diagnostics: Visual inspection for bulging capacitors, burnt parts, fuse/varistor check.
  • Disassembly & Cleaning: Power board removal, dust removal, heatsink cleaning.
  • Measurements: Voltage checks, continuity testing, short-circuit detection in primary/secondary.
  • Component Replacement: Desoldering/soldering new capacitors, MOSFETs, PWM controllers, diodes, optocouplers.
  • Backlight Driver Check: LED driver or inverter diagnostics, current/voltage verification on LED strips.
  • Testing: Extended operation on test bench or real setup, temperature and stability monitoring.

Optionally include software installation for monitor service menu access post-repair.
