Just received my Lilliput 629GL TS monitor, it will work for a minute when powered on but will turn completely blank/white after that.

Can't even power off by power button or the remote. If I unplug and plug back the power it will works for another few minutes. Tried car adapter same issue as the wall jack power supply.

Haven't have a chance to try the touch screen yet, since can't have the display to stay for more than a few minutes.

Checked all the cables connections.
Tried 2 different laptops dell and sony with difference screen resolution settings and refresh rates

Searched the posts but couldn't find anything similar, need to know if I should try something else before I send it back for exchange. The user manual doesn't really help either....

Thanks
