A few days ago my receiver failed to switch on when I hit the "power" button on either the unit face or the remote (the only response I could get was the faint clicking sound the reciever has always made when being switched on). However, after some frustrated repitition, I was able to switch the unit on and for a few days everything was fine. Then again last night the same issue occured. Nothing in the troubleshooting guide comes to close to describing my issue. I know there is power going to the unit, as the red light on the front remains lit as though it were still in Standby. The unit is wired into the same surge protector I've had it on for over a year and every other device plugged into it (TV, Xbox, DVD) works fine.
I've had this happen a number of times with my receiver. This trick from the Troubleshooting guide in the owner's manual usually does the trick:
If an unusual condition in the display window or malfunction
occurs, reset the unit as follows.
1 Press the POWER button to turn off the power.
2 Press the POWER button while pressing the ENTER button.
Everything stored in memory after purchase is canceled.
If the power cannot be turned off in step 1 because of a
malfunction, reset by disconnecting the AC cord and carry out

But first try removing the power cord and press and hold the power button on the front face of the unit for 30 seconds..
Remove the battery on the remote and press any key on the remote for a few seconds.
Replace the batterys on the remote and power cord on the Monitor.
Try to power up the unit and see if that works.
The Monitor/TV have a CMOS battery which retains all your setup information. By removing the power and holding the power button, you may be able to clear the memory and reset the unit.
Possibly due to a power failure, control unit needs to be reset. Hit reset button. Hold for 30 seconds. Also no fire typically due to nozzle clogged, no fuel which means control will shut down. Water in fuel will also shut boiler down. Clogged filter will decrease fuel flow. Electric eye face is dirty which will also shut it down. If you have a two line system, open up bleeder and see if you get a good flow. Check electrodes for burned ends or out of gap specs.
> The next time I try to turn the unit on the remote will not work or I can not turn the unit on with the switch on the side. This statement leads me to believe the IR receiver and associated set-top button circuit may be at fault. If you haven't hammered the set to pieces yet, try this; next time it fails to respond to the remote, put the remote in your freezer for 2-5 minutes (not longer, the batteries won't appreciate it) and then try it again. If it then functions normally, then a certain integrated circuit (PT2222 or PT2221) may be from the same lot as mine and is abnormally sensitive to warmth.If this does make a difference, try removing the battery compartment cover and intentionally leave the remote face down. If these tests don't seem to make any difference to the remote, then it is likely that the receiver end in the set is faulty.
Failure to warm would suggest the fuser unit is failing and the machine is failing to reach the temperature that toner melts and fuses to the paper. The machine should display error 76 or 77.
Try this ONCE only!! till the after 99 bit. Hit menu, *,2,8,6,4 quickly if all the button flash and maintenance is displayed enter 99. Now if the error reoccurs you need to replace your fuser unit as it failed as opposed to just malfunctioned.
It will melt if there is a problem and you keep repeating this process. So please only once. If it takes you a few goes to get into maintenance modes its ok but the reset of 99 do only once.
Do the buttons on the front panel of the unit work?
If so, try doing this:
Hit the tivo button, go down to messages and setup and into to system information. Go down a few screens until you see remote code. Hold (on your remote) the tivo button and pause button for about 5 seconds. Then hit 0-9 on your remote to set the code. It's a single digit code only. You'll see your remote light flash. Now, try hitting the back button and see if your remote works. If it does, great. If it doesn't that means one or more of the following:
1) Your remote is defective 2) Your IR receiver on the unit isn't working correctly.
If #2 is the problem, you'll need to open up the unit, powered down! and make sure the thin, greyish ribbon cable in the front of the motherboard is 100% in. If it's not all the way in, it will cause issues.
