Computer Repair, TV Repair Industry Terminology

The vendor approved an advanced replacement for the failed drive so the client won’t see downtime. | We’ll ship you a replacement main board today; return the defective one within 10 days. | Advanced replacements usually require a credit card hold until we receive the bad unit.

Clip your antistatic strap to ground before you touch the T-Con board. | The strap’s 1 MΩ resistor protects you while discharging static. | ESD audits check that techs are wearing wrist straps on the bench.

The TV has sound but a dark screen—likely a backlight failure. | We replaced two shorted LED strips in the backlight array. | CCFL backlight inverters tend to shut down on lamp fault.

Our bench fee covers diagnostics if you decline the repair. | The bench fee is credited toward the repair if you proceed. | We raised the bench fee to align with the time spent on triage.

The GPU needs BGA rework with a controlled reflow profile. | We reballed the Southbridge to resolve intermittent boot. | Invest in a proper BGA rework station before attempting this.

Update the BIOS/UEFI to the latest version before swapping CPUs. | Corrupted UEFI NVRAM caused the boot loop. | Disable Secure Boot in UEFI to load the diagnostic OS.

The BSOD points to a faulty storage driver. | We pulled the minidump to analyze the BSOD code. | RAM errors can trigger random BSODs under load.

This OLED shows news ticker burn-in along the bottom. | Run a white screen test to separate burn-in from temporary image retention. | Burn-in isn’t covered by the manufacturer’s warranty.

Bulging caps on the PSU indicate classic capacitor plague. | We recapped the power supply with low-ESR parts. | The main board’s startup issues were due to dried-out capacitors.

Vertical lines suggest a COF/TAB bond failure on the panel edge. | COF driver ICs feed the panel via flex—repair requires bonding gear. | Squeezing the bezel briefly restores the image—classic COF issue.

Rocking the connector causes dropouts—likely a cold joint. | Reflow the tuner shield joints to fix intermittent signal. | The dull, grainy pad under the regulator was a cold joint.

Beep the fuse for continuity before replacing the board. | The LVDS trace is open—no continuity from connector to T-Con. | Use diode mode to check for shorts to ground.

Our COGS went up after LED strip prices increased. | Track labor in COGS to get a true gross margin. | Bundling parts lowers effective COGS per job.

Log the TV repair in the CRM and attach photos. | The CRM triggers follow-up emails after pickup. | Integrate the CRM with the ticketing system for visibility.

We used ddrescue for a sector-by-sector clone before file extraction. | This drive needs cleanroom work due to head damage. | Always image first—never run repairs on the original.

Three dead pixels fall within the panel’s policy limits. | Use a red/green/blue test to spot stuck vs dead pixels. | Panel replacement is the only permanent fix.

Check the 12 V rail with the DMM under load. | Set your DMM to continuity before probing the fuse. | A True RMS DMM is better for non-sinusoidal signals.

Corrupt EDID in the TV’s EEPROM stopped 4K modes from working. | Read EDID to confirm the display supports HDR10. | An EDID emulator fixed the handshake issue.

We flashed the BIOS chip in-circuit via SPI. | Rewriting the HDMI port’s EDID EEPROM restored video. | Use a SOIC clip to program NVRAM without desoldering.

Always use ESD-safe bags for loose boards. | The HDMI IC likely failed from ESD during handling. | Humidity control reduces ESD events in winter.

The laptop’s eDP cable has a kink causing flicker. | eDP replaced LVDS on newer panels. | Verify eDP lane count before ordering replacements.

Schedule a field service visit for the wall-mounted TV. | Keep van stock to raise first-time fix rate on-site. | Use geofencing to optimize field tech dispatch.

Flash the TV firmware via USB to fix HDMI handshake bugs. | Interrupting a flash can brick the main board. | We used ISP pads to flash the EC firmware.

Stocking LED strips boosted our FTFR on TV backlight jobs. | Tight triage improved FTFR from 62% to 79%. | FTFR is a core KPI for field service.

We quote flat-rate for ‘no power’ TV repairs. | Flat rates simplify approvals but require time standards. | Exceptions apply for liquid damage under flat-rate.

Our gross margin improved after renegotiating parts costs. | Track gross margin per technician and per SKU. | Low-margin screen repairs may not be worth taking.

HDCP handshake failure is causing a black screen on HDMI 1. | Use an HDCP 2.2-compliant input for the 4K player. | Swapping the HDMI switch IC resolved HDCP errors.

The set supports HDR10 but not Dolby Vision. | Incorrect tone mapping made HDR look washed out. | Calibrate HDR modes separately from SDR.

Disable HDMI-CEC to stop the console from turning on the TV. | CEC conflicts caused random power cycling. | The main board’s CEC line was shorted to ground.

Use the 6 mm nozzle and 260 °C for that QFN. | Preheat the board before hot-air rework to avoid warping. | Shield nearby parts during hot air rework.

Running a pixel refresh cleared the retention. | That faint logo is temporary image retention, not burn-in. | Vary content to prevent retention on menu screens.

We target 8 turns/year on common LED strips. | Slow-moving T-Con boards hurt our turnover. | Tighten min/max levels to improve turnover.

The CCFL inverter shuts down due to a shorted lamp. | Replace the inverter caps to restore backlight. | Check for HV arcing near the lamp connectors.

We unbricked the main board via JTAG. | The SoC’s JTAG pins are exposed on the test pads. | Use JTAG to dump firmware when the device won’t boot.

Our KPIs include FTFR, MTTR, and NPS. | Publish KPI dashboards weekly for the team. |We’ll add ‘first-contact resolution’ as a KPI.

Use higher temperature for lead-free rework. | Tin whiskers from lead-free solder caused a short. | We reflowed the board with SAC305 alloy.

A damaged LVDS cable caused colored vertical lines. | Verify LVDS voltage rails at the T-Con connector. | LVDS was replaced by eDP in newer laptops.

No HDMI inputs work—the main board likely failed. | Board-level repair beat the cost of a main board swap. | Confirm standby voltage before condemning the main board.

Reducing MTTR required better parts availability. | Our average MTTR for TV no-power is 2.1 days. | MTTR is a contractual metric in the SLA.

Post-repair surveys lifted our NPS by 12 points. | NPS correlates with repeat business and referrals. | Train CSRs to improve detractor recovery and NPS.

The PC powers on but there’s no POST—check RAM and CPU. | No-POST with beep codes suggests a video issue. | Strip to minimum config to troubleshoot no-POST.

OEM LED strips fit better than aftermarket ones. | Using OEM parts preserves warranty coverage. | The OEM service manual lists T-Con voltages.

Scope the PSU output for ripple under load. | The clock line on the eDP bus is missing—confirmed on the scope. | Use a x10 probe for high-frequency signals.

We use a 2.5x parts markup to cover overhead and warranty risk. | Transparent parts markup builds trust. | Adjust markup on scarce main boards.

Standby 5V is present—PSU is likely good. | Replace bloated caps on the PSU first. | Check PFC and PS-ON signals at the PSU connector.

The system hangs at POST—watch for error codes. | No display but POST beeps indicate RAM failure. | Use a POST card on older motherboards.

Our QC checklist includes HDMI, Wi-Fi, and backlight tests. | QA reviews reduced returns by 15%. | Add a pixel test pattern to QC for every TV.

We reflowed the HDMI switch IC to fix cold joints. | Use flux and controlled profiles for safe reflow. | Reflow without root-cause can be a temporary fix.

Open an RMA for the DOA main board. | The vendor denied the RMA due to physical damage. | Track RMAs to recover costs on defective parts.

No image with backlight on—check the T-Con rails (VGH/VGL/AVDD). | Replacing the T-Con cleared half-screen artifacts. | A shorted panel can kill the T-Con repeatedly.
