Common Armco TV faults we repair (symptoms → what it usually means)
| Symptom | Likely cause(s) | GossTech approach |
|---|---|---|
| TV won’t power on / no lights | Blown standby fuse, PSU (power board) failure, faulty power socket | Visual inspection → measure standby voltages → replace fuses or PSU board; test on bench |
| TV has power but no picture (sound OK) | T-Con board fault, LVDS cable, panel backlight failure | Check backlight with flashlight test → test T-Con board, replace if needed |
| Dim or flickering screen | Backlight inverter / LED strip or power rail instability | Measure LED driver voltages → replace LED strips or inverter circuits |
| Lines, bands or distorted image | Faulty T-Con, damaged ribbon cables, panel defects | Replace/ reseat ribbon cables → swap T-Con for diagnosis → recommend panel replacement if needed |
| No sound (picture OK) | Audio amp failure, speaker fault, mute/firmware issue | Test audio amplifier voltages → swap speakers or amplifier IC → firmware check |
| Remote not working | Remote batteries, IR receiver, pairing issue (smart TV) | Test IR sensor, pair remote, replace IR board if faulty |
| Smart TV apps fail / Wi-Fi issues | Firmware bug, corrupted OS, Wi-Fi module failure | Firmware update/reinstall → Wi-Fi module replacement if hardware faulty |
| No signal / tuner problems | Antenna/cable, tuner module, DVB-T2 configuration | Test external feed → replace tuner module or reconfigure channels |
| HDMI/USB ports not working | Port damage, mainboard port circuit failure | Inspect physical ports → repair or replace port assemblies on mainboard |
| TV boots then restarts / boot-loop | Mainboard firmware or damaged capacitors on power board | Firmware recovery → replace swollen capacitors and faulty power components |
Note: some panel (LCD/LED) faults are not economically repairable — in such cases GossTech will explain repair vs replacement options and costs.
How GossTech diagnoses & repairs Armco TVs — step-by-step
- Intake & history: We record model number, serial, symptoms, and any prior repairs. (Armco model IDs are on the back label or in the OSD menu).(Armco)
- Visual & safety check: Exterior checks (burn marks, swollen capacitors, water ingress), fuse continuity, mains plug/supply.
- Power verification: Measure incoming mains, standby voltages (5V/12V rails), and check PSU board components (capacitors, diodes, transformers).
- Board-level testing: With schematic/experience we test mainboard, T-Con, audio amp, and tuner circuits for correct voltages and signals.
- Signal tracing: For video issues we trace LVDS/T-Con data and use known-good donor boards to isolate faulty modules.
- Firmware & software: Smart TV OS updates, factory reset, or re-flash when corruption suspected.
- Parts replacement: Use tested replacement boards (power board, mainboard, T-Con, LED strips, speakers, Wi-Fi modules). We prefer genuine or high-quality compatible parts.
- Final QA: Full functional test (multiple inputs, channels, apps, audio/video) and burn-in to ensure problem solved.
- Customer handover & warranty: Repairs come with a parts-and-labor warranty (details provided on invoice).
Typical diagnostic table (what we check first)
| Inspection/test | Why we do it | Outcome/next step |
|---|---|---|
| Visual capacitor check | Bulging/leaking caps cause instability | Replace bad capacitors on PSU |
| Standby LED present? | Confirms if PSU is supplying standby | If no, check fuse/standby regulator |
| Flashlight test (no picture) | Distinguish backlight vs panel | If faint image visible → backlight issue |
| Swap T-Con board | Identify T-Con vs panel fault | If picture returns → replace T-Con |
| Firmware re-flash | Fix smart OS corruption | Reinstall official firmware |
| Multimeter/oscilloscope checks | Verify signal / clock lines | Trace faulty ICs / replace board |
Parts & replacements — what’s repairable
- High-repair success: PSU (power supply) boards, T-Con boards, mainboard component swaps, speakers, LED strips, HDMI/USB ports, tuners, Wi-Fi modules.
- Low-repair success / cost-prohibitive: Cracked or severely damaged panels (LCD glass), full-screen burn or dead pixels across panel. When a panel replacement cost nears or exceeds a replacement TV, we advise replacement.

Pricing & transparency
GossTech provides a clear diagnostic report and a written quote before any parts are fitted. Our quotes identify whether the fault is board-level repair (usually more economical) or requires replacement modules/panel. We stock common replacement parts for Armco models, and where a part must be ordered we'll notify you and supply ETA and source.
Preventive care & maintenance tips for Armco TVs
- Use a good-quality surge protector or UPS to protect the TV from power surges and unstable mains.
- Keep ventilation free — avoid enclosing the TV in a tight cabinet while it’s running.
- Avoid leaving static images for prolonged periods on smart TVs to reduce risk of image retention.
- Clean vents and back of TV with dry, soft cloths — don’t spray cleaners directly onto screens.
- Update smart-TV firmware when manufacturer updates are available to fix bugs and security patches.(Facebook)

- Scenario B — Smart apps crashing: Firmware corrupted → backup settings, re-flash official firmware → resolve app stability and restore connectivity.
- Scenario C — Horizontal lines across screen: Fault in T-Con board → swap T-Con → image restored; replace T-Con and test.
