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.

Power supply board have dead leakage gases componnents call capacitors.These capacitors are dead or will not work properly.These capacitors alway bulges up it top or puff up it top.U know basic electronic's and soldering?Take ur tv aparts.Go all around the power supply board searches for these bulges or puff it top capacitors.Replaced these leakage gases capacitors,ur power will return to normal functions,and work.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
Sounds like there is a short on the power board or the power board has gone faulty.
Look on the power board to see if any of the capacitors are bulged or if there are any other components burnt out.
The TV is going into protect mode because of an over current, which points to a short on the board or a component has gone short circuit.
Thanks
Shutdown with a 3x blink pattern occurs if the 12v from the power supply (GF1 or GF2 depending on model) is lost at CN6153/pin 6 to the AU Board Q1224 to Sub Micro IC1205. The suspects, in order of likelihood, are (1) Power supply and (2) the AU board.
