Screen shows "Nissan" for a fraction of a second at start then only randomly stripes and dots .Radio still works .
First guess was faulty screen ,but that was all wrong ,bought one from ebay and the problem remain.
Checked signals out from navi with scope ,looks good except YS wich is a steady 4.8 V (?) ,instead of rectangular signal.
Have nt checked yet the signals at screen plug ,will do at next attempt ,maybe a faulty cable from navi to screen ?
Customer says that from time to time the screens come back for very short period of time .
Any ideas ?Also like to know if the screen can be tested on the table ,so far I cannot turn on the spare screen ,even with
2 lines of supplies ,R,G,B and H+V sync signals..
Thanks !
