Hello, If i plug the TV power cable in 2 sec back light is on and the logo Bravia appears on the screen for about 6sec and then back light goes off, no image, no sound. Power button switches green LED on and off, the SONY front panel logo as well. The remote control switches green LED on and off. If I unplug the TV in stage off and then plug it again, and try to power on, I can’t see any logo and back light is off as well. All voltages are fine. No errors. If I unplug any connection cable to the backlight boards, the blinking red LED appears. Any ideas? Sony Bravia KDL-46Z5100 Thank you
Hi @dankolov , Just verifying that you tried the USB port on the back of the TV?
(click on image to enlarge for better viewing) Also here’s a link to the service manual for the TV. You can use it online but it is a bit slow but it has schematics etc which may help. Use the index to find the page that you want and then scroll down to the bottom and type the page number in the box and click Go to get to the page
@dankolov “No backlight, no image, no sound” since you measured all the voltages and found them to be “fine” then you will have an issue with either the main board or the T-con board. This “ If I unplug any connection cable to the backlight boards, the blinking red LED appears” is actually what it is supposed to do.
