Purchasing guide | 24 September 2026
A photograph of a display that lights up answers only part of a buyer's question. For the 78350367 monitor listing, request identification and a clearly defined function-check record before dispatch. Our product photographs show the screen, controls and rear connection; they are not evidence that a particular unit has passed a functional test.
Match identity and configuration before requesting a video
Send the old monitor's complete rear label, machine serial number and installed connector photographs. Preserve every suffix and revision shown on the label. Ask the supplier to identify the offered hardware reference and any software or configuration requirements relevant to that machine. Do not infer compatibility from a similar bezel or matching plug shape.
State whether the required unit is new, used or repaired, and ask that condition to be recorded in the quote. If a substitution is proposed, request its documented basis and any required setup work. Do not assume the monitor is ready for use on every machine merely because it powers up on a bench.
Agree an acceptance checklist tied to the offered unit
- Identification: a readable label photo and order reference connecting the record to the unit being supplied.
- Physical condition: screen cover, case, mounting points and connector terminals photographed clearly.
- Display: a continuous recording showing startup and relevant screens under stated test conditions.
- Controls: demonstration of each applicable button and its observed response, without assuming unverified touchscreen functions.
- Configuration: confirmation of any required language, setup or machine-specific configuration and who will perform it.
- Limitations: a written distinction between bench checks completed and machine functions not tested.
A video of menus operating does not prove communication with every machine system. If integrated communication is a purchase requirement, agree an appropriate verification method and record its limits. Do not energise unidentified terminals using a guessed wiring diagram.
| Option and inspection condition | Parts cost scope | Workshop time | Downtime and delivery considerations |
|---|---|---|---|
| Repair a confirmed supply, wiring or connector fault when the monitor remains serviceable. | Identified electrical connection or harness repair items. | Diagnosis, repair and verification on the machine. | Prevents an unnecessary display order; timing depends on the confirmed fault. |
| Replace a confirmed faulty monitor with a verified compatible unit. | Monitor plus specified mounts or connection items, if required. | Installation, any necessary configuration and functional verification. | Include setup availability as well as confirmed dispatch in the schedule. |
| Specialist repair of the existing display where repairability and scope are established. | Agreed repair components and service charge. | Assessment, repair and documented function checks. | Compare the specialist turnaround and shipping with replacement lead time; repair is not always faster. |
Compare evidence as part of the quotation
Illustrative comparison: Offer A supplies a front photo; Offer B identifies the unit and documents its controls under stated conditions. Ask Offer A for the same evidence before making a like-for-like decision. Specify how unresolved test items will be checked after installation. No claim of tested performance, universal compatibility or guaranteed downtime reduction is made for the photographed monitor.
Request a clearly scoped quotation
Send the identification details and inspection findings above to GUANGZHOU JIAJUE MACHINERY EQUIPMENT CO.,LTD, together with quantity and destination. Ask us to state the exact supplied components, supporting identification evidence and confirmed dispatch terms in the quotation.
These are purchasing checks, not a machine-specific repair procedure or a record of a completed customer repair. Product photographs show visible features; they do not establish internal condition, test performance or compatibility. Installation and testing should follow the applicable equipment service information.
