1. Open cell (Vert. line / Horizontal Line defects) — COF Replacement

Horizontal or vertical lines on the screen are a common failure caused by poor solder connections, failed driver ICs and poor bonding of the COF’s conductive traces on the glass. Disappeared image, lacking color, black image as vertical and horizontal block on LCD panel can occur on your LCD monitors, Laptops and/or LCD TV. In this case, driver IC’s or COF needs replacement. COF is replaced by our specialized staffs in our LCD laboratory. COF replacement process requires specialized equipment for pulse heated anisolm chemicals. Our proprietary equipment is able to execute tight process control over heat and pressure profiles precision positioning and alignment because of our advance computerized control heat sealed equipment. We are proud to point out that we have trained staff and quality machines.

2. Open cell (ITO Defects)

If your LCD screen has a stuck or dead pixel (a point on the screen that is always lit or always dark), it is usually due to a transistor malfunction or uneven distribution of liquid in the liquid crystal display (TFT LCD). This can be often fixed.

3. BLU defects (Light leakage / Low light emission / LED replacements/ CCFL defects)

For getting image from Lcd panel, There is a light source in the back side of the Lcd glass. Power of this constant light source needs to be kept in same level by an electronics circuit. This light source and the electronics circuit which controls the light source is called as BACKLIGHT Unit. Innovent use high brightness and high contrast backlight to replace your defective backlights. These backlights increases display contrast and brightness. These also provide clearer and sharper images. If contrast is out of adjustment or if there is blur, disappear images, image tremble on your lcd panel, The electronics circuit or the light source needs replacement.

4. Polarizer replacements

The polarizer is a film that is applied to the front of lcd panel.

Polarizer film provides deeper looking colors; permits a wider viewing angle in brighter environments; increases surface transmission; protects panels from fingerprints and scratches. The front polarizing film is often damaged due to Accidents or abuse, seen as scratches on the front of the screen. The film must be stripped to the bare glass and the screen cleaned and prepared for reapplication of the new polarizing film. Both the removal and subsequent reapplication of polarizing film need to be conducted under stringent antistatic conditions. This process is materialized in dust-free area which is inside of clean room.

Polarizer-replacementsUsually, the polarizer film gets scratched, damaged, torn or melt due to spilling over hot liquid or due to temperature inside LCD glass. In this respect, User will realize like defectiveness of contrast and color, unclear Image…etc. In any of these cases; the polarizer film needs replacement.

5. Driver Boards / Inverter Board repair

  • Gate PCB Repair (BGA IC)
  • Source PCB Repair (BGA IC)

There are two electronics circuit boards on LCD panel. These electronics circuit boards; Gate and Source PCB’s, determine and control images on LCD panel. New technological BGA, QFP and SMD electronic components are used on electronics circuit boards. BGA component drives on the right conductivity between electronics circuit and component with small solder balls. Re-balling, Removing and replacement of BGAs on PCB requires specialized equipment. We have this special BGA equipment that process removing and replacement of BGA, QFP and SMD electronic components in our laboratories. Our laboratories are fully equipped with new technological equipments and measurement tools. If There is lacking image or If all characters are in white colors or not getting image on your LCD monitors, laptops, LCD TV; Probably electronics circuit board of your LCD panel is defective. All PCB repairs can be carried out in accordance with RoHS directives.
