Question about Samsung SIR-T451 DirecTV DTV Receiver
In the past week the reciever is stcuk on boot mode. I turn on the unit and it is not gooing beyond the boot stage. I turn off and on the unit and even diconnect it from the power for a few days. Nothing chaged. Is there anything I can do?
It happen the same thing to my 5-year-old Samsung SIR-T451. I just tried a combination of POWER button and the other three button on the front. What seems to work was the POWER and MENU button at the same time, and I was able to get past the BOOT process and straight into the MENU screen. Once there I re-started the ON-AIR signal acquisition process. It seems to be working fine now. Well see.

There are about 150 electrolytic capacitors in the thing.
Those are NOTORIOUS for being un-reliable. One of them
probably blew out. Easy to replace, part available for a few cents at
Radio Shack, (OBSERVE PLARITY). Look for Swollen, burst tops,
leaking brown goo, and a stinky smell. Easy fix, I fixed BOTH of
my Samsung tuners with this issue, a T451 and a H260F. T451 PC board has 5 screws, plus 2 on back, plus 2 nuts on RF connectors. Pinch power supply plug to removed, flex flat cable just pulls out. Lift back of board then slide board back to remove. I suspect they used LEAD solder not the newer lead-free as solder is shinny and no RoHS label on PCB.
MOST common cause of dead electronics is electrolytic caps!
