SOURCE: picture and sound cuts off ,greem stb light keeps blinking

How many blinks do you get? Depending on the amount of blinks you can figure out what the issue is.

If it blinks 6 times you can get the fix at

No power RED Standby LED flashes 6 times/KDF55XS955, KDF60XS955, KDFE55A20, KDFE60A20

They have other fixes for E60A20

Sony Bravia KDL-xbr4 Replaced TCON board All worked great for a week Had an issue w/ HDMI cable at the box fixed it and now tv comes and the goes off to 6 blinking red lights


6 red flashes- backlight issue, bad main board, or power board or inverter boards- check standby volts on power board. "backlight on" volts should be 3-5v from main logic board then 24v to inverter


Have this from a youtube link find BUT
Better is to look first also on bad leaking or bulged capacitors thats better to replace in the bad components to get a repair because active components died on bad capacitors but after a while because on the build-in protection circuit by faults like deformed or leaking capacitors and even several fuse resistors then after replace a complete board again after a while you will may be get the same kind of problems again, take If you find some or much bad capacitors replacements 10 volts dc higher . begin with control on the power supply first of all.

Hi,
4 blinks indicated of backlight malfunction. The unit shutsdown to avoid overload to the inverter board.
Check the backlights, busted backlight has a physical indication of fault like blackened end, crack end. You must replaced the busted one and your unit will back to normal operation again.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
