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.

Four blinking red lights.


you can have the inverter board replaced...instead of the entire panel.
KDL 40S2010: inverter part # 178950032, you will also need 2 spacers..part # 289765511
you're looking @ 200-300$ for the inverter and 5-10$ a piece for the spacers.

KDL-46V2500: inverter part # A1251295B
you're looking @ around 500-600 $ for the part
