How to repair Television Lvds Cable?

Here are some methods for repairing the LVDS cable of a TV:
Check the connections
– Make sure that the LVDS data cable and the power cable are firmly connected. If a poor connection is found, you can unplug and then plug in the data cable again to see if the display problem can be solved.
- For poor contact caused by oxidation, dust and so on, you can use an eraser to wipe the gold-plated contacts at the end of the LVDS cable connected to the screen, or clean them with anhydrous alcohol and then dry them.
Test the circuits
– Use a multi-meter to check whether the voltages and signal lines on the circuit board are normal. If there are obvious burn marks or circuit breaks on the circuit board, it may be necessary to replace the circuit board or relevant components.
- Measure the resistance of each pair of signal lines. Under normal circumstances, the resistance of each pair of signal lines is approximately 100 ohms.
Deal with faults
– If the screen flickers due to a problem with the screen driver board, you can try to power off and then restart to reset the driver board. If this doesn’t solve the problem, then the driver board needs to be replaced.
- When image problems such as screen distortion or colored stripes occur, if the LVDS signal format is selected incorrectly, you can enter the “LVDS MAP” screen parameter selection option in the bus to make adjustments; if the A group and B group of the LVDS cable are connected in reverse, you can cross them over again to solve the problem.
- If the LVDS cable is seriously corroded or damaged, after determining its part number, you can try to search for and purchase a new cable online for replacement.
