IRRemote lib with Arduino mega 2560 (SEND comand to sony TV)

Hello, i´m trying to use the IRRemote with my arduino mega. i read this topic,28434.0.html
and work for all devices but my sony TV doesn´t work with the send the command

for (int i = 0; i < 3; i++) { // Send a burst of three commands
irsend.sendSony(0xa90, 12); // Sony TV power code

and nothing happens

Thanks for any help.

try changing the delay time!, in my case, (sony audio receiver) working delay time is 40 (not 100),
try other values as 45 (some samsung tvs) or 50…, the time between each command is important

int delaysony         = 40;

void loop ()
for (int i = 0; i < 3; i++) {
          irsend.sendSony(0x540C, 15); // Sony audio encendido

Sorry for my english,  :D


Thanks man i will try this and post the result.
