How GossTech diagnoses a Vizio TV — step-by-step
- Client intake & symptom capture — We record model number, firmware version (if available), and precise symptoms. Photos of the TV and error indicators are helpful.
- Remote troubleshooting (if possible) — For smart-TV/software issues we guide simple checks (power cycle, firmware update, factory reset). If not resolved, we schedule a technician.
- Initial inspection on arrival — Technicians inspect external ports, remote, visible damage, power indicators.
- Bench diagnostics (in-shop) — We remove the back cover and test: power board voltages, main board, T-CON, LVDS cable continuity, LED backlight voltages, capacitors and fuses. We use oscilloscopes, multimeters, and test jigs.
- Component-level repair or replacement — Depending on diagnosis we repair at board level (replace capacitors, regulators, ICs), replace sub-boards (power board, T-CON, main board), or replace LED strip arrays. We only replace the TV panel when absolutely necessary and after client approval.
- Firmware & software verification — For smart-TV faults we update or reflash firmware, clear corrupted app data, and test network modules.
- Quality control & testing — Post-repair we run extended tests for hours to ensure stability, verify picture/sound across inputs, and calibrate picture settings.
- Handover — We provide a report of repairs performed, replaced parts, warranty terms, and preventative tips.
Pricing transparency & turnaround
- Free diagnosis quote for many Nairobi locations (phone or site-visit): we’ll tell you the estimated diagnosis fee and expected turnaround.
- Common minor fixes (HDMI jack replacement, firmware update, remote/IR fixes): typically same-day or 24–48 hours.
- Board-level repairs: 2–5 business days depending on parts availability.
- Panel replacements: lead time depends on panel sourcing; we provide honest cost vs replacement advice.

Preventative care tips (keep your Vizio TV healthy)
- Keep vents clear — avoid covering the TV or placing it in a tightly enclosed cabinet without airflow.
- Use a surge protector — power surges are a common cause of board and power-supply failures.
- Avoid constant max brightness — reduces stress on backlight and power circuits.
- Update firmware regularly — smart-TV OS updates can fix app and connectivity issues.
- Clean ports gently — use compressed air and avoid liquids near connectors.
- Professional install for large/wall-mounted units — improper mounting can stress the cabinet and connectors.
Warranty & parts
- Repaired parts and labor by GossTech include a limited warranty (terms provided on each invoice).
- We use high-quality replacement parts; where possible we install genuine or OEM-equivalent boards and components.
- For panels (expensive), we explain cost/benefit and never replace without client consent.
Example case studies (realistic examples of fixes we do)
Case 1 — Vizio TV with backlight failure (black screen but audio): Customer reported sound but black picture. We performed LED backlight voltage checks, found failed LED string. Replaced LED strips, tested for brightness uniformity and color balance, returned TV with 6-month parts warranty.
Case 2 — Vizio Smart TV random reboots: Diagnosed overheating and failing electrolytic capacitors on the main board. Replaced capacitors, updated firmware, ran stress tests — no further reboots.
Case 3 — HDMI input damage (after multiple devices plugged/unplugged): Replaced damaged HDMI jack and cleaned input board; advised on proper use and surge protection.
FAQs
Q: Do you repair Vizio TVs under warranty?
A: If the TV is under manufacturer warranty, we recommend contacting Vizio or the retailer first. We can, however, provide paid diagnostics and repairs for out-of-warranty sets. We’ll inform you if a manufacturer-authorized repair is required.
Q: Can you replace a cracked TV panel?
A: Yes, but panel replacement can be costly and — for older or low-cost models — sometimes exceeds the TV’s value. We give an honest estimate and replacement options.
Q: Do you offer on-site repairs?
A: Yes — for wall-mounted TVs or locations where transport is impractical. Some repairs require in-shop bench testing; in such cases we’ll collect the unit and return it after repair.
Q: How long do repairs take?
A: Minor fixes are often same-day; board-level repairs 2–5 days depending on parts; panel replacements depend on panel availability. Call for an accurate estimate.
