Plasma televisions were once the gold standard for deep blacks and cinema-like colour. Even though they’re older technology now, many homes and businesses in Nairobi and across Kenya still rely on plasma TVs — and when they fail, you want a trusted technician who knows plasma technology inside out. GossTech specializes in diagnosing and repairing plasma televisions (plus LED, LCD, OLED, QLED and Smart TVs) with expert, component-level service and clear, honest advice on repair vs replacement.

Below you’ll find a pillar guide that covers: the areas we serve in Nairobi and nationwide, the types of TVs we repair, the common plasma problems we fix, GossTech’s step-by-step diagnostic and repair approach, parts and replacement guidance, maintenance tips, FAQs and clear next steps to get help fast.

Types & brands of televisions GossTech repairs

Although this post focuses on plasma TVs, GossTech is experienced with a wide range of television technologies and brands:

Technologies: Plasma TVs, LED TVs, LCD TVs, OLED TVs, QLED TVs, Smart TVs, and legacy CRT sets (limited).
Top brands we service: Panasonic (major plasma brand), Samsung, LG, Sony, Philips, Toshiba, Sharp, JVC, and other regional/house brands. If you have a unique brand or model, we’ll check compatibility and parts availability.

Why choose GossTech for plasma TV repair?

  • Deep experience with plasma technology: Plasma repair requires specific skills (high-voltage boards, PDP panels, driver IC knowledge). Our technicians have trained on plasma chassis and service manuals.
  • Component-level repairs: Wherever possible we repair components (power boards, sustain/drive boards, inverter assemblies) rather than replace whole units — saving cost.
  • Transparent diagnostics: We explain faults and present repair options (repair, part replacement, or replacement advice) with costs and risks.
  • Genuine parts sourcing: For many panels and boards we source original or tested replacement boards; where panels are unavailable we recommend alternatives.
  • Nationwide support: Nairobi appointment booking plus shipping/partner repairs across Kenya.

Common plasma TV problems — causes, diagnosis & repair (table)

Symptom Likely cause(s) How GossTech diagnoses it Typical repair approach
TV won’t turn on / no LED Failed power supply board, blown fuses, bad standby circuit Multimeter checks of standby voltage, fuse inspection, visual board check Replace/repair power board, replace blown fuses, replace standby ICs
TV powers on but no picture (black screen) Bad sustain/drive boards, faulty panel drivers, panel failure Measure all main voltages, test inverter outputs, swap driver boards (if spare available) Repair/replace sustain or Y/M driver boards; if panel cells are dead advise on replacement cost vs repair
Distorted image, lines across screen Failing driver ICs, damaged scan/sustain boards, loose LVDS/connectors Signal tracing, inspect flex cables, board substitution testing Replace driver/sustain boards; reseat or replace LVDS ribbon cables
Colour issues / green or pink tint Failed color processing IC, bad LUT or plasma phosphor aging Signal injection tests, IC testing, board-level inspection Replace color processing IC or board; calibrate colours after repair
Flickering / intermittent image Weak capacitors, thermal faults, loose connectors Thermal testing (recreate flicker), inspect capacitors, continuity tests Replace electrolytic capacitors, reflow solder joints, secure connectors
Sound but no picture Video processing or mainboard failure, T-CON issues Check video outputs, HDMI/LVDS signals, inspect mainboard Repair/replace video/mainboard or interface boards
Heavy buzzing / electrical smell Overheated transformer, failing capacitors, power supply fault Visual smoke/heat signs, capacitor ESR testing Replace transformers/capacitors; service power supply boards
Remote or control issues Remote sensor, IR board or firmware errors IR signal testing, board-level checks Replace IR sensor board or reflash firmware
Vertical or horizontal collapse Scan/sustain circuits failing, bad oscillators Oscilloscope tracing of scan signals Replace oscillators or scan circuitry on sustain boards
Panel physical damage Cracked plasma glass, shattered cells Visual inspection Panel replacement (often not cost-effective) — evaluate replacement TV option

How GossTech diagnoses plasma TV faults — step-by-step

  1. History & symptoms: We start by asking what happened (power surges, lightning, transport shock) and reproducing the fault.
  2. External inspection: Look for physical damage, burnt components, swollen capacitors, water ingress or odors.
  3. Power & standby checks: Measure standby voltages and fuses using a multimeter; ensure the power supply is delivering correct rails.
  4. Board-level testing: Isolate and test mainboard, sustain boards and inverter sections. We use measured voltages and test points on service manuals.
  5. Signal tracing: For picture issues we trace video signals from input ports to mainboard to plasma driver boards.
  6. Component testing: Capacitors, diodes, transformers and driver ICs are tested in-circuit where possible or removed for bench-testing.
  7. Substitution testing: When we keep spare known-good boards for a particular model we may swap to confirm faults before ordering parts.
  8. Final verification: After repair we run stability tests at various brightness levels and inputs to ensure durable repair.

Repair options & realistic guidance

  • Board-level repair: For many plasma faults (power board, sustain/driver boards, capacitors, transformers) we perform component replacements or full-board swaps. This is often the most cost-effective approach.
  • Panel replacement: If the plasma glass/panel cells themselves are damaged or irreparably degraded, panel replacement is technically possible for certain models but panels are rare and usually expensive. GossTech will evaluate panel availability and give honest guidance.
  • Upgrade recommendation: For older plasma sets where replacement parts are unavailable or expensive, we’ll recommend replacement with an LED/OLED TV and can advise models and trade-in/installation tips.
  • Firmware & software fixes: For Smart TV functions or mainboard firmware issues, we perform software updates where available.

Honest advice: Plasma TVs are mature/legacy technology. Repairs are worthwhile when the fault is board-level and parts are available. When panel replacement is needed, we’ll explain cost vs value and suggest alternatives.

Parts & sourcing

GossTech sources tested original parts where possible. For discontinued plasma models we work with trusted parts suppliers and refurbished boards. When OEM parts aren’t available we may source high-quality equivalents and ensure they meet safety and functional standards.

Pricing, scheduling & warranties

  • We provide a clear diagnostic quote after inspection.
  • Repair quotes list parts, labor and any testing performed.
  • Where feasible, we offer limited warranty on repaired boards/parts (specific warranty terms provided on the repair invoice).
  • To arrange collection, on-site visit, or shipment-to-workshop, contact 0723613664 or info@gosstech.co.ke and we’ll confirm the best option for your area.

(Note: for scheduling specifics and exact warranty length please contact GossTech directly for the most current terms.)

Maintenance tips to extend a plasma TV’s life

  • Keep ventilation clear: plasma TVs run hot — allow space around the set for airflow.
  • Avoid high static images for long periods (reduces image retention risk).
  • Use a stable power source and surge protection — lightning and surges are common causes of fatal board damage.
  • Clean carefully: use a dry microfiber cloth for screens; avoid liquid cleaners that can seep into seams.
  • Reduce extreme picture brightness settings to minimize panel wear.

Frequently Asked Questions (FAQ)

Q — Do you repair all plasma TV brands?
A — We repair most major plasma brands (Panasonic, Samsung, LG, Philips, Sony, etc.). If your model is rare we’ll check parts availability and advise.

Q — Is it worth repairing an old plasma TV?
A — If the fault is board-level and parts are available, repairs can be cost-effective. If the plasma panel itself needs replacement, we’ll provide a cost comparison versus buying a modern replacement TV.

Q — Do you do on-site repairs?
A — For many straightforward faults we can do on-site diagnostics and minor repairs in Nairobi; for complex board-level repairs we bring the TV to our workshop. Contact us to confirm options for your estate.

Q — Will repair affect picture quality?
A — Component-level repairs restore original function; where panels are aged you may still notice reduced brightness or color shifts — we calibrate after repair where possible.
