What Causes the Sagitar Display Screen to Go Black?
2 Answers
The reasons for the Sagitar display screen going black include poor line contact, aging signal cables, power supply module failure, circuit design defects, and screen aging. Poor line contact: It is necessary to promptly check whether there is a loose connection in the lines. It is recommended to reconnect the loose position properly. Aging signal cables: If the power signal cable is aging, it can be replaced with a new one. Power supply module failure: Prolonged use of the screen may cause the power supply module to fail. It is advisable to have it checked or replaced at a 4S shop. Circuit design defects: If there are defects in the circuit design, this is beyond the scope of self-repair. Therefore, it is necessary to take it to a repair shop for inspection and repair or direct replacement. Screen aging: The display screen has a certain service life. When the screen ages, bad pixels may flicker. Solution: Replace it with another display screen. If the issue disappears, then a new display screen needs to be installed.
I've encountered this issue several times. Last time when I was driving my Sagitar on a long trip, the display suddenly went black, which really startled me. Actually, the most common cause for black screen is poor contact in the wiring, especially in Volkswagen cars where connectors tend to loosen over time. When I took it to the repair shop last time, the mechanic first checked the corresponding 10-amp mini fuse in the fuse box, and sure enough it was blown. Replacing it only cost five yuan. System crashes are also common - just hold the power button for ten seconds to force a reboot. If these simple methods don't work, it might be a burnt-out screen motherboard or a broken ribbon cable. My friend's car had its ribbon cable shaken loose on a bumpy road. For such cases, you need to find a professional shop to dismantle the center console for inspection - don't mess with the wiring yourself. Finally, a reminder: never repeatedly turn the screen on and off when parked, as it can easily trigger overheating protection.
