I regret to inform you that there is another display that developed a serious issue:

 

 

In this photo, the unit should display a blank, black background (other than the "TankAuto" shortcut and the Windows taskbar).

 

At first, restarting the unit solved the problem temporarily, but now the image retention / distortion is continuous.

 

The unit itself had been delivered in May 2024 and was installed in an OPT in December 2024. It was working fine until about 2 weeks ago.

Can I ask for a booting method or advice before opening an RMA request?



Answer:


We suggest following the below steps before shipping back:

  1. Change a computer or signal source.


2.  Start the OSD factory mode (R/G/B/black/white pattern) – connect power but not any signal cable. Push OSD button VOL+ (third button) then click POWER (first button) to enable the factory mode. Check if the stripes pattern still on the screen.

  1. Reconnect the tcon board as the below connectors in red rectangles (power must be off when reconnecting.)

  1. (When  power on) slightly pet the black mylar area on the screen to check if the stripes changing. This is a risk method so you could choose not to do.
