Quality Control Checklist for Televisions From Bangladesh

If you import televisions, this televisions quality control checklist gives you a practical way to check a shipment before it leaves Bangladesh. A television is judged on the screen: a bright dot, uneven backlight or a rocking stand shows at once. Use an agreed sampling plan rather than sets the factory selects. ISO 2859-1 specifies an acceptance sampling system for inspection by attributes, indexed in terms of the acceptance quality limit (AQL), applicable to end items.¹

Why this checklist matters

Televisions concentrate risk in a large, fragile electrical product: the panel decides picture quality, the tuner, inputs and software decide whether the set works in the destination market, and the stand and packing decide whether it arrives safely.

A written checklist removes interpretation. Each point is checked against the approved sample and specification, and recorded as pass, fail or not applicable. Set acceptance numbers per defect class in the purchase order.¹ See the AQL acceptance quality limit explainer.

Before you start

Do not begin until the references are complete: an approved sample per size, panel type and market version, the purchase order and specification with rated voltage, frequency and power, resolution, tuner standard and language set, stand details, and the packing specification. Agree the sampling plan in advance,¹ and draw the sample randomly across sizes, panel lots and cartons.

Confirm the safety reference before bulk marking is printed. IEC 62368-1:2023 is a product safety standard for audio, video, information and communication technology equipment that classifies energy sources and prescribes safeguards against them, to reduce the likelihood of pain, injury and, in the case of fire, property damage.² Confirm which edition and national version the destination requires.

The full checklist (numbered, printable)

Dimensions, stand and components

1. Confirm each sampled carton contains the television, stand and screws, remote with batteries where named, power cord and manual.

2. Measure screen diagonal and cabinet width, height and depth on each sampled set, with and without the stand, against the specification, recording actual values.

3. Fit the stand to each sampled set as the manual directs: screws seat firmly, the set stands level without rocking, and no crack opens at the fixing points.

4. Check wall-mount fixing points where fitted: thread, spacing and depth match the bracket pattern named in the specification.

5. Weigh sampled sets where the specification gives a weight, and check panel type, resolution and market version on the carton against the unit.

Panel and picture

6. Power each sampled set on the destination voltage and run the test patterns named in the plan: full white, black, red, green, blue and a gray scale.

7. Check on the black pattern for bright pixels, and on the white pattern for dark pixels, recording count and position per set. A bright pixel shows as a white dot on a black screen and a dark pixel as a black dot on a white screen, and ISO 9241 defines classes of pixel defects against which the agreed class is checked.³

8. Check for clusters of defective pixels close together, which read as one visible fault even where single defects pass.

9. Check backlight evenness on white and gray patterns: no bright corners, clouding or fixed dark patch.

10. Check panel and bezel for cracks, chips, scratches, pressure marks and trapped dust, at corners as well as center.

11. Check color and gray-scale steps for banding and tint shift against the approved sample under the same signal.

12. Check viewing from the angles named in the specification for a watchable picture with no sudden color reversal.

Tuner, inputs and smart functions

13. Tune each sampled set to the destination broadcast standard and confirm it finds, stores and recalls the test channels in order.

14. Check every input named in the specification, such as HDMI, USB and antenna, with a real signal: picture and sound pass, no loose port.

15. Play a test file from USB where the specification names formats, and confirm picture and sound match the sample.

16. For smart sets, connect to a local network, open the named applications, and check language, region and time against the destination version.

17. Check menu language, subtitle and audio options against the market version, and confirm a factory reset returns the agreed first-start state.

18. Check program guide or teletext functions only where the specification names them.

Sound

19. Play speech, music and a low tone at low, mid and high volume and listen for rattles, buzzing, distortion and one silent channel.

20. Check left and right balance by covering each speaker in turn, and confirm stereo stays on the correct side.

21. Check volume steps, mute and audio outputs named in the specification, including headphone output where fitted.

22. Check lip sync on broadcast and USB content against the sample, with no delay the viewer can notice.

Safety, power and energy evidence

23. Check the rating label on each sampled set: model, rated voltage, frequency and power must match the order, carton marking and manual.

24. Check power cord, plug type and fuse where required against the market version, with no damage or loose pin.

25. Run each sampled set for a sustained period at normal brightness and check for failed start, shutdown, overheating smell, sparking or a hot spot on the back.

26. Confirm safety evidence where the order requires it names this model and lot, under the standard agreed for the destination. IEC 62368-1:2023 classifies energy sources and prescribes safeguards against them.²

27. Review on-mode and standby power evidence where required, and confirm the report names this model, size and lot. IEC 62087-3:2023 specifies the determination of power consumption and related characteristics of television sets, including LCD and OLED sets.⁴

28. Confirm the power report uses the named signals. IEC 62087-2:2023 specifies the signals used to determine power consumption of equipment such as television sets, and the signals for peak luminance ratio.⁵

29. For sets for the European Union, check the energy label and product information before printing. Regulation (EU) 2019/2021 lays down ecodesign requirements for electronic displays, including televisions, covering energy efficiency, off and standby modes and material efficiency.⁶

Markings, manuals and substance evidence

30. Check rating and warning markings are legible, durable to a rub by hand and identical across the sample, including the destination marks named in the order.

31. Check the manual in each sampled carton: language set, model name, diagrams, stand steps and safety warnings must match this model and destination.

32. Check on-screen and carton claims, such as resolution, tuner type and smart features, against the specification, and record unsupported claims as failures.

33. Where the destination restricts substances, check the supplier declaration names this model. Directive 2011/65/EU restricts certain hazardous substances, such as lead, mercury and cadmium, in electrical and electronic equipment.⁷

Packing and cartons

34. Confirm each set is packed as directed, screen protected by the named film, corner protectors fitted, and no hard accessory pressing on the panel.

35. Check that stand parts, remote, batteries where named, cord, manual and warranty card are present in each sampled carton.

36. Check that barcode, model and size stickers scan and match the purchase order, and that carton markings match the set inside.

37. Handle sampled cartons as the carrier would, with the stacking and drop checks named in the specification: no crushed corner, split seam or loose contents.

38. Weigh and measure sample cartons, and check count against the packing list.

39. Record every failure by set, carton and defect type, photograph it, and hold the unit until disposition is agreed.

Common failures and how to fix them

The most frequent failure is a panel defect found only on a full-screen pattern: a bright sub-pixel on black, a dark patch, or a pressure mark from packing. Stop, run the patterns on a fresh sample from the same panel lot, compare counts against the agreed class, and segregate the lot. Next is a tuner or language mismatch from the wrong market version in bulk: hold those sets, compare the version code on carton, label and software against the order, and reflash or replace before shipment.

A rocking stand usually starts at a short screw or cracked fixing post: refit one set as the manual directs and re-check the group. Sound rattles point to a loose speaker or back cover: open one unit with the supplier and re-check the same assembly period. Crushed corners point to weak packing: repack as specified and repeat the handling checks.

Above the agreed acceptance level, options are re-inspection after sorting or rework, documented partial acceptance, or rejection.
