TV screen press is a professional equipment used for repairing LCD TV
screens. It mainly repairs screen display abnormalities or structural
damage problems through physical pressing technology. The specific
functions and uses are as follows:

1、 Core functions
Fix screen cable malfunction
To address issues such as bright wires and flashing screens caused by

loose or broken cables, the circuit connection can be restored by replacing

or re pressing the cable (COF).
Internal and external screen fitting repair
Re press the separated inner screen (liquid crystal layer) and

outer screen (glass cover) to eliminate issues such as delamination and

bubbles, ensuring display uniformity.
Local component replacement
It can accurately replace damaged COF cables or glass covers,

avoiding the whole screen from being scrapped and reducing maintenance costs.
2、 Typical operation process (taking LCD TV as an example)
Fault location
Power on to detect the damaged cable position and confirm the

COF component that needs to be replaced.
Disassembly and pretreatment
After disassembling the screen, clean the residual glue and fix the

edge plate to ensure that the pressing surface is flat.
Compression operation
Use a screen press to precisely align the new wiring or cover plate,

and bond it with conductive adhesive by high-temperature pressing.
Curing test
After completing the compression, check the firmness, reassemble and test the display effect.
3、 Applicable maintenance scenarios
Bright line/flashing screen repair: Vertical/horizontal bright lines caused by poor contact or breakage of the ribbon cable.
Degumming/bubble treatment: Display blur or touch failure caused by separation of inner and outer screens.
Low cost screen replacement: Replace the external screen glass (rear screen) or local wiring, while preserving the intact LCD layer.
4、 Technical advantages
Accuracy: Supports micrometer level alignment for large-sized screens (such as TVs over 55 inches), reducing manual errors.
The standard equipment is 14-65 inches.
Compatibility: Compatible with different brands and models of LCD TVs to meet diverse maintenance needs
Economy: Compared to full screen replacement, maintenance costs are reduced by more than 50%.
Note: The operation of the screen press machine requires the

cooperation of professional equipment (such as hot air guns,

defoamers) and materials (conductive adhesive, stickers).

Improper operation may result in secondary damage.
