The poblem is in the TV, exceptionally times replay after push any remote control key several times.
I check with an oscilloscope the IR receiver and the signal is good until the control board, but in the pin 76 of the SAA5647HL I have some pulses instead of the eceiver signal.
I changed the remote receiver and it isn´t the solution. According with the uprocesor circuit diagram the pin 76 would be pullup to Vcc until a remote signal appear, but in that pin It is always present a pulsed signal between 1 v y Vcc and, when remote signal appear the change is between 1v and Vss. I suspect in a synchronization problem but don´t have any adjustment.I changed the remote receiver and it isn´t the solution.
