Report "- 16V & 5Vs all got. 5. Upon connecting the power adapter & switching ON, briefly the backlight comes ON then OFF. I guess this is normal since the 21" LCD TV i got (Thomson) also does the same upon powering ON the switch. Please request if you need further info. Thank you. I've got a reply from Jamie867 with a link to the service manual. Unfortunately the svc manual is not for the 27" unit. The 30" & 27" shares the schematic"
