MAIN board : CV9203H-A42
PANDA 385L RUNTKB070ZZPN
PANDA 385R RUNTKA071ZZPN LC390TU1A-S
The problem is the one described in the argument, the sound is ok, but there is no image.
Backlight is on.
On the board (T-CON PANDA 385L RUNTKB070ZZPN - PANDA 385R RUNTKA071ZZPN), integrated on the display the 12 volt voltage is ok.
IC3: HX8915-E is powered (see photo), but there is no voltage on the terminals.
HX8915-E is an equivalent of as15?
The problem is HX8915-E?
Thanks and good job.
