Turnip:
Hi folks,

Had my first 17IPS10-3 and 17MB25-3 set in today. Backlight comes on, then after 2 seconds blue LED lights up on LVDS then backlight goes out followed by blue LVDS led.

Note that there is but one inverter tranny and it reads the same on both secondaries.

Secondary caps look good and diodes check OK.

Any thoughts ?   - Thanks  -  Chris
