No picture hits hard—blank screens from power boards or T-Con failures. Prologic at Luthuli Avenue starts with standby light checks. Blinking LEDs code errors like overheating. No lights mean PSU collapse.
Signal generators test HDMI inputs. Burnt capacitors smell confirms faults.
Diagnostic Methods
Voltage rail mapping finds drops. Load tests stress components. Thermal imaging spots cold solders.
Firmware dump verifies corruption.
Common Culprits
PSU capacitors fail from surges. HDMI boards fry on arcs. Panel timeouts from drivers.
Dust blocks heat sinks in humid rooms.
Repair Process
Board swaps use anti-static mats. Reflow stations revive chips. Power cycle scripts reset.
Panel tests with test patterns confirm.
Tools Employed
Fluke meters measure ripple. Signal analyzers decode HDCP. JTAG debuggers reprogram.
Advantages
Saves 80% vs new TV. Restores 4K clarity. Warrantied results.
