Hi Momaka, good to have you back!
Perhaps the last thing you could try is pull ANT+5V_SW high by using a 100 Ohm resistor to connect ANT+5V_SW to either a 3.3V or higher voltage rail. If the TV still doesn't come on (my guess is most likely it wouldn't)
measure the voltages on pins 5, 19, 24, 25, 26, 27, 28, 30, 31, 32, 45, 46, 47, 50, and 51 of IC2302 and let me know what these voltages are. As a last attempt, I'll see if I can make some sense out of them.
24=2.21V 25=2.21V 26=3.06V 27=2.91V 28=3.22V 30=3.22V 31=3.21V 32=0.01V 45=0.01V 46=0.01V 47=3.20V 50=0.03V 51=0.20V Shorting between pin 47 & 48 also suspends the lamps same as with IC2303.
Would be possible to eliminate the suspend mode to off and on, I think they use this mode in some hotels, no suspend mode to save power?
