Dead STB any ideas?

[kenorakid]

Got up today turned on tv"scrambled channel" -reboot STB switch at back -switch back on again on and nothing it was dead, left an hour and now it works, "overheating" issue? I leave it on 24/7, my house is dry in winter and I notice this year when I touch the box it cuts out for a second or 2 but not other winters

This is just me shooting out some ideas. Double check your AC plug and transformer. Totally unrelated but same type of problem. I got a Wii that if left plugged in it won't start up. I unplug from the wall and plug it back in it works fine. That is an issue with the AC transformer. Not saying thats your issue but good place to start. Just shooting in the dark again. Wonder if theres a short some where?
Good luck let us know what you fine.

How many satellites are you looking at and what type(s) of LNB(s) and/or switches are attached?

It could be an excessive DC current draw through the LNB input port has caused something to finally go belly up in the tuner power supply circuit. (hopefully not)

The LNB power is only rated at 500 mA MAX on most FTA receivers, putting too much out there can cause an overload and in the long run cause internal damage to the DC power circuitry for the LNB.

Also a bad or wet coax connector or water in the coax can cause a problem, on some installs the coax if it's the copper plated steel core stuff can rust if it has gotten wet at some time, this rust or corrosion can cause a resistive short this can cause a loss in DC voltage and a higher then normal current load, this would cause the internal DC power supply regulators to shut down to prevent any damage to them, letting it sit powered down caused them to cool down and reset, they may work for a while, but how long is anyone's guess.

These are best guesses at my end.
