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

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.
