Good Morning,
We have a Sharp PN-E702 that loses backlight after 20 seconds. We are trying to rule out wheather its the display or the supply. On the 14 separate supplies we have about 180v supplying the screen. On the return from the screen we only have between 1v and 1.7v. After disconnecting the return voltage on the 14 separate pins the voltages range between 70v and 90v. Any help would be much appreciated.
Best Regards Peter
