2) How GossTech diagnoses and repairs each problem — step-by-step

Below we explain, problem by problem, our typical diagnostic flow and repair approach. This is designed for transparency (and to help search engines index in-depth).

Important note: technicians begin with non-invasive checks, then progress to measured electronic diagnostics using meters, ESR testers, power supplies, and (where applicable) signal analyzers. We avoid unnecessary part replacements.

1. TV won’t power on (no lights)

Diagnosis steps

• Verify mains voltage and test power outlet.
• Check power cable and external switch/SMPS fuse.
• Open chassis (workshop) and test standby rail voltages and main power supply outputs with a multimeter.
• Inspect for blown fuses, bulging capacitors, burnt resistors, or shorted components.

Repair

• Replace blown board fuse or power cord.
• Replace faulty SMPS (switch mode power supply) components: MOSFETs, diodes, capacitors, regulators.
• Repair PCB traces, replace power board if necessary.
• Test extended run and apply thermal/ surge protection advice.

2. TV powers on but screen is black (sound present)

Diagnosis

• Check backlight circuit (LED strips or CCFL in old sets).
• Test inverter/backlight driver voltage.
• Confirm T-con and LVDS cable connections from mainboard to panel.

Repair

• Replace backlight LED strips or inverter board.
• Replace or reflow T-con board or LVDS cable.
• If panel is defective, we advise replacement (costly) and provide parts quote.

3. Blank screen and no sound

Diagnosis

• Confirm mainboard is booting using status LED codes.
• Test power rails to mainboard and T-con; check for blown components.

Repair

• Repair/replace faulty mainboard or reprogram firmware if corrupt.
• Replace connectors and faulty capacitors.

4. TV turns off randomly / reboots

Diagnosis

• Temperature logs, power rail stability, firmware check, and capacitor ESR testing.

Repair

• Replace failing capacitors on power board, update firmware, repair cooling and ventilation, fix power button/switch.

5. Intermittent picture, flickering, artifacts

Diagnosis

• Inspect HDMI/input signal path, test with multiple sources, check mainboard GPU/SoC and memory.

Repair

• Replace faulty HDMI port, shield cable paths, reflow or replace mainboard components, or replace mainboard.

6. Vertical/horizontal lines

Diagnosis

• Test T-con, LVDS, and panel driver chips.

Repair

• Replace or repair T-con board, reconnect LVDS cables, or replace the panel if driver ICs are damaged.

7. Dim backlight / low brightness

Diagnosis

• Test LED driver and LED diode string continuity, measure backlight current.

Repair

• Replace LED string or driver IC, calibrate brightness settings.

8. Dead pixels / bright spots

Diagnosis

• Determine if pixel faults are panel internal (permanent) vs surface damage.

Repair

• For small numbers of dead pixels, panel-level repair possible (often temporary). For widespread defects, panel replacement recommended.

9. Colour problems

Diagnosis

• Color calibration checks, inspect video IC and DAC paths.

Repair

• Replace faulty DAC/ SoC chips, recalibrate LUTs, or reflash firmware.

10. No sound / distorted audio

Diagnosis

• Test internal speakers, amplifier circuits, audio IC and software settings. Connect external speakers to isolate.

Repair

• Replace faulty audio IC, amplifier board, or speakers; fix audio board solder joints.

11. Remote control issues

Diagnosis

• Test IR sensor, remote battery, pairing status on smart TVs.

Repair

• Replace IR sensor, reprogram remote, replace internal receiver module.

12. HDMI/input not working

Diagnosis

• Inspect for physical damage, short circuits, or controller faults.

Repair

• Replace HDMI port or mainboard; test with multiple sources.

13. Smart TV / Wi-Fi issues

Diagnosis

• Network diagnostics, firmware version check, memory/storage tests.

Repair

• Reconfigure network, reflash firmware, replace Wi-Fi module or NAND memory if corrupt.

14. Overheating / smoke smells

Diagnosis

• Immediate power down, PCB inspection for burnt components, test temperature sensors.

Repair

• Replace burnt components, add thermal pads, clean vents, and replace heat-sensitive parts.

15. Burn-in / image retention (OLED)

Diagnosis

• Visual inspection, run pixel shifting and diagnostic patterns.

Repair

• For severe burn-in, panel replacement is usually required. Minor retention may be improved with software patterns.

16. Tuner / reception problems

Diagnosis

• Test signal strength, replace antenna cabling, check RF tuner module.

Repair

• Tune or replace tuner module, advise antenna upgrade, or repair coax connectors.

17. Power surge / lightning damage

Diagnosis

• Check for multiple burnt ICs and fused power rails.

Repair

• Replace damaged boards, advise installation of surge protectors.

18. Physical screen cracks

Diagnosis & Repair

• Panel replacement only — we supply genuine or compatible panels with fitment quotes.

19. Firmware/boot loop / bricked TV

Diagnosis

• Serial debug, USB firmware recovery if supported.

Repair

• Reflash firmware, repair corrupted flash memory, or replace mainboard.

(For every repair we provide a diagnostic report and a transparent quote before proceeding.)

3) Repair methods & parts we use

• Genuine parts & high-quality compatibles: power boards, T-con boards, mainboards, LED strips, inverters, speakers, HDMI ports, Wi-Fi modules, panels.
• Diagnostics tools: digital multimeter, ESR capacitor tester, oscilloscope, programmable bench power supply, T-con adapters, service firmware loaders.
