I´d guess a problem with bad leds in the backlighting after seeing several other videos here... have the same problem on a TX-42ASR600.... turns on screen ok for a couple of seconds, shuts down and the power led turns from green to blinking red...
Dis u find the solution ? Check cables and cold solders. In my cause i replaced all strip LED's bar for new ones . Can be repaired just the burned LED's or remove the bad led and leave a solder jump, but it gonna pressure others LED's and degrade / burn in few weeks ou months.
what was the solution here? I have the same problem. I check all LEDs individually and all seems to work.
