1 connect power cord
2 red led on
3 turn power switch
4 led off
5 backlight shining bright for one second
6 backlight off for one second
7 backlight shining dark for one second
8 backlight off
9 red led on for 7 seconds
10 led off
11 backlight shining bright for one second
12 backlight off for one second
13 backlight shining dark for one second
14 backlight off
15 red led on for 7 seconds
...."goto 10" :evil:

i replaced the PSU but it stayed the same.
No picture on screen, no matter which button I press on the remote control it only flashes the led on the TV.

Does somebody has any idea?

Sorry for my bad english. :-)
