Are LVDS cables interchangeable?
No, most LVDS cables have a unique pinout that is based on the LCD panel that is being used and the SBC (single-board computer) driving the LCD. Most of Quadrangle Product's LVDS cables are custom cables. LVDS cables are very popular in electronic communication devices, including computers and smart devices.

What voltage is LVDS?
LVDS voltage swing range from 250mV(minimum) to 450mV (maximum) with a typical value of 350mV. Because the voltage swing is very low and will require less time to rise and fall, it is able to achieve higher operating frequency than CMOS and TTL with the same slew rate.

What is the full form of LVDS?
Low Voltage Differ- ential Signaling (LVDS) is a high speed (>155.5 Mbps), low power general purpose interface standard that solves the bottleneck problems while servicing a wide range of applica- tion areas.
Does LVDS support touch?
The Verdin DSI to LVDS Adapter features a touch connector compatible with the Capacitive Touch Display 10.1" LVDS.
What is LVDS on motherboard?
The LVDS panel connector is a 30-pin (dual-row) shrouded white header of 1.00-mm pitch, supporting video data, clock, and EDID signals, as well as panel logic power.
What is LVDS cable?
This cable connects LCD panel to logic board. A damaged display data (LVDS) cable will cause the display not to show image.
What to do if LVDS socket is not damaged?
If the LVDS socket on the logic board is not damaged then simply replace the LVDS cable.
What happens if you turn off a diode and it reverts back to lines?
When and if it does work if you turn it off and on and it reverts back to lines them a diode or capacitor is likely damaged and this is a technical repair requiring SMD and a microscope, as well as a donor board to rescue parts from. Without test parts you have a difficult task ahead.
Can you remove LVDS cable from logic board?
NOT recommended procedure but while the laptop is on I have removed the LVDS cable from the logic board and slipped it in and out a few time until it worked. When and if it does work if you turn it off and on and it reverts back to lines them a diode or capacitor is likely damaged and this is a technical repair requiring SMD and a microscope, as well as a donor board to rescue parts from.
Can LVDS cables be replaced?
Damaged LVDS cables can be replaced-- but as one responder pointed out it is not a part that is normally sold separately. You most likely place to find a replacement is by buying a display assembly that is non working and salvage the cable.
Can logic board work with external monitor?
2) Remember that the problem can be on the logic board and not the screen-- meaning you can have a logic board that works with external monitor and not the internal screen-- but to no fault of the screen. So inspect the logic board LVDS connector carefully with a loupe to see if it has any signs of visible damage like liquid shorting out or melting plastic connectors.
What is LVDS in electronics?
It turns out that these screens use a standard called Low-Voltage Differential Signaling (LVDS) that conveys information through the polarity of the voltage differential ΔV (a few hundred mV) between 2 wires. The two wires must have the same length and are twisted together to reduce susceptibility to Electromagnetic Interference (EMI). Though these details are not important for this project, further information can be found here and here.
What does O stand for in a cable?
The notation is such that O stands for "Odd", E for "Even", C for "Clock", while + and - the positive and negative of the differential inputs. Looking at the mappings again, we can see that the cable connects to the odd clock and odd pairs 0-2. Indeed, the screen datasheets confirm the pinouts, but this does not quite explain what even and odd mean, or why the cables are different.
Where to find LVDS cables?
TIP: LVDS, USB and Coax cables can be found in the Electronic Parts Catalog (EPC) by first identifying the main harness that contains the needed cable and then looking for the cable references in the accompanying graphic. (Fig. 2)
How to replace a cable on a car?
When replacing a faulty or damaged cable, first disconnect the cable connectors at both ends. Route the new cable along the harness and use tie-straps to attach the cable to existing harnesses or brackets. Be sure to not pinch the cable or bend it more than a 2-inch (5 cm) radius. Tape or foam can be used to prevent the cables from rattling if needed.
How to stop cable from rattling?
Tape or foam can be used to prevent the cables from rattling if needed. With the new cable installed, reconnect the connectors to the components. Cut the connectors off of the older cable as close to the harness breakout as possible without damaging the harness.
What cables does GM use?
Many GM vehicles are equipped with Low Voltage Differential Signaling (LVDS), Universal Serial Bus (USB) and Coaxial (Coax) cables for a number of screen and camera connections as well as high-speed data transmission.
What is GM cable repair?
The GM cable repair strategy is to replace these cables instead of repairing when addressing related vehicle issues. Never attempt to repair these types of cables on a vehicle. The entire cable/harness or component must be replaced.
Do Ethernet cables come with connectors?
Ethernet cables come without the connector, but with the terminals crimped on the cable. The cables are a universal length to service as many applications as possible with the fewest part numbers. As a result, the cable received may be slightly (<500 mm) longer than the original cable contained within the factory harness. Any extra length of cable should be coiled up and secured.
Should Ethernet cables be replaced?
Ethernet Cables. Ethernet cables should be replaced and not repaired as well. Service harness kits are released per vehicle that contain a length for each leg/peripheral device. If an Ethernet wiring repair kit is not available, the entire harness must be replaced.
What is the normal RSDS voltage?
3. # Confirm whether the RSDS value is correct, normal RSDS is about 1.2v, and the signal difference is about 200mV; At the same time, we can confirm the resistance between RSDS signal (normal 100 or 50 ohms) and RSDS resistance to ground. If the voltage is NG, check if the ASIC and X-COF are hot.
Can you switch the display on a LCD?
Phenomenon: full-screen vertical stripes (not gradient stripes) appear on the LCD display. In most cases, the display cannot be switched.

Is confirmation of gate IC fault only for analysis when interested?
The confirmation of gate IC fault is only for analysis when interested, this method is not recommended.
Can you disconnect the COF one by one?
3. # If all of the above are OK, you should try to change the COF. You can disconnect the COF one by one to determine which IC is NG.
