Our LG TV diagnostic & repair process (what to expect)
- Initial contact & problem capture — You call, email or submit a request via the website. Give model number, serial number (if available), symptoms, and when it started. Photos or a short video of the fault help.
- Remote troubleshooting — Our technician will guide simple checks you can do safely (power socket, cables, reset). This often resolves setup and connectivity issues.
- On-site or workshop assessment — If the fault requires hands-on work, we either arrange an on-site visit (for wall-mounted or commercial displays) or a safe pickup/drop-off to our workshop.
- Detailed diagnosis — In the workshop we run a full electronics diagnosis: power trace, display signal trace, firmware integrity, audio circuits, connectors and panel inspection.
- Repair estimate & approval — After diagnosis we provide a clear, itemised quote (parts + labor). We explain repair options (repair vs panel/mainboard replacement vs replacement TV) so you can choose.
- Repair using quality parts — We use genuine LG spare parts when available, or high-quality OEM equivalents. All repairs include testing and burn-in to ensure stability.
- Quality checks & handover — Before handover we run final checks (picture, sound, smart features, ports) and explain preventive care tips. We support follow-up service and warranty on repairs performed.
Note: GossTech provides transparent quotes; you approve repairs before we proceed.

Tips to extend the life of your LG TV (preventive maintenance)
- Keep ventilation clear — avoid enclosing the TV in tight cabinets without airflow.
- Use a surge protector — protects against voltage spikes common during storms.
- Gentle cleaning — use a soft microfiber cloth, avoid harsh chemicals.
- Power down during long absences — unplug or switch off at the socket.
- Firmware updates — keep webOS/firmware updated to avoid app and streaming problems.
- Avoid extreme brightness settings for long periods — prolongs panel life.
Transparent pricing & warranties
GossTech provides a clear written estimate after diagnosis. We use quality parts and back repairs with a warranty on labor and replaced components — details are included on each invoice. For major replacements (e.g., panels), we explain cost vs value and present options.
