Sony Simple IP Protocol

[phongvucba]

Please help me !
I use the code above to turn the TV on and off but it does not work?
My television is sony bravia 79' X900B.
Does anyone know how to turn it off via HTTP?
----------------
require('socket')
ip = '192.168.1.16'
-- power-on =1, off=0
on = '*SCPOWR0000000000000001\n'
off= '*SCPOWR0000000000000000\n' --SCIRCC0000000000000001
sock=socket.tcp()
sockettimeout(1)
a=sock:connect(ip,20060)
if giatri==1 then
b=sockend(on)
alert('send OK')
else
b=sockend(off)
alert('send OK')
end
sock:close()
end
------------------------------------------
function check_tv()
require('socket')
sock=socket.tcp()
sockettimeout(2)
ip = '192.168.1.16'
cmd = '*SEPOWR################\n'
a=sock:connect(ip,52323)
if a==1 then
b=sockend(cmd)
if b==24 then
c=sock:receive()
if c=="*SAPOWR0000000000000001" then
alert("tivi đã bật")
return 1
else
alert("tivi đã tắt")
return 0
end
else
alert("Send failed: ")
end
else
alert("connect failed")
end
sock:close()
end
--------------------

Am I wrong?
