Why would a PC, directv receiver, or TV not boot after just being on?  It sounds like it begins to start up (like 2 seconds of fan noises) but then dies and begins again over and over.  If you leave any of these 3 devices unplugged for 30 minutes they will work the next time you try. For me the product doing it is the directv receiver.  I found these other 2 items while researching the problem on the internet (neither of them had a solution). I read suggestions about heat, capacitors, and power supply. I replaced the power supply, no capacitors on this thing are mis-shaped, I took the lid off and pointed a high velocity fan at it. None of those worked.  I had a pretty good idea it wasnt heat because this happens even if the receiver is only plugged up for 5 seconds but I wanted to say I tried.   Do you guys have any ideas?  Not only do I own the receiver but it has my precious recordings on it :)

Still sounds like overheating to me. When it happens shortly after powering on (especially after an extended off) it usually means the thermal compound under the heatsink is dried up or the heatsink isn't firmly attached anymore.


I have replaced the thermal compound on various consoles and computers though have yet to do any sat/cable boxes.

Some kind of hardware or software failure.


Sorry I can't be more specific.

That is pretty basic. I usually start with the power supply, and then branch into either RAM, motherboard, RAM or hard drive.

Divide and conquer. AFAIK you can run the TV, the DirectTv and the PC separately. The smart thing would have been to do so. Start out by validating the TV, and then the DirectTV receiver and last on the list should be the PC.

I will try that, thanks!

 

 

Arnyk, I said I found 2 of the devices on the internet.

mdavej, I said I own the receiver.

Are you sure you own it? Many people think if they paid $200 at Best Buy, they own it. That's still a lease. I realize there are some owned DVR's out there, but not many. It's worth confirming with DirecTV before you go to too much trouble.


One obvious thing to check are caps around the power supply. If any are bulging at the top, they're blown and need to be replaced.

That is also the reason you cannot get them at places like Best Buy any longer. You can sign up for the service but you can't walk out with a receiver in your hands.
