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?
The receiver wont pass the booting , I did unplug the unit and also hold the power for awhile, with no resultsThe receiver wont pass the booting , I did unplug the unit and also hold the power for awhile, with no results
I guess that this is a design issue because I have the very same problem with the boot, I try the same power off, hold the power button with no resultsI guess that this is a design issue because I have the very same problem with the boot, I try the same power off, hold the power button with no results

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!
I have the same problem. Do you remember which capacitor(s) you have replaced? Thank you in advance for your help!I have the same problem. Do you remember which capacitor(s) you have replaced? Thank you in advance for your help!

Remove batteries from room stat,turn off the electrical supply to reciever unit.
Turn back on the electric to reciever unit,the red light should be
on,press the top "manual" button,the green light should come on and
boiler should fire (assuming the programmer is in an "on" period)
Press the bottom button,and keep it pressed,then press the top button
until the green light flashes,stand about 6 feet away,and refit the
batteries to the stat while observing the reciever unit,either the red
or green light (cant remember which) should flash to show the 2 units
are syncronised.
Another basic test if all seems ok,when turning the stat up or down,when
the green light on the reciever unit comes on or goes off,its usually
accompanied by an audible "click" ive found,that if this is not
happening, the reciever unit does not switch either on or off,may be
intermittant.
Replacement is the only cure. garden led light
A lot of different equipment including but not limited to TV sets, computer towers you name it has this issue.
What I suspect is that if the unit has to be turned on several times before it works you have bad filter caps in the units power supply---standby supplies are on 7/24 if the unit is plugged in.
Look in the units power supply for puffed up caps that look like these.
The reciever will go into protection mode when there is a short in the speaker wires or the amplifier was overloaded. What I would do first is verify that none of the speaker wire connections are loose at the back of the reciever or at each speaker. And verify that none of the wires are making contact with each other. Then label each speaker wire as you remove them from the reciever so you can re-install them correctly. After you have disconnected the speaker wires try unplugging the reciever for 10 to 15 minutes. Most recievers have a self-resetting overload protection switch and this should reset it back to normal. Now try plugging the reciever back in and turn it on without the speaker wires connected. It should be out of protection mode now. If it is still in protection mode verify that there is not a reset switch somewhere on the back of the reciever. If it is not in protection mode now then proceed to connect one speaker set at a time and turn on the reciever to see if it goes into protection mode. If it goes into that mode after connecting a speaker then that speaker is the cause of the problem. If it does not go into the mode after all speakers are connected then try turning the volume up. If it goes into protection mode then there could be an internal short on the amplifier or a incorrect OHM rated speakers connected to reciever. Verify that the speakers are rated the correct OHMS.
most of the receivers come with a cooling fan inside see if its working they usually work when you turn the volume up,, if its working that means you are playing it to loud if you lower the volume a little it will play just fine..( if the fan inside is not working thats the reason it goes into protect mode and it means you must have it repaired,, it goes into protect mode to prevent furter damage to the unit or the speakers,,
If the light on the media reciever doesn't come on then the power supply in that needs to be replaced by a service tech. If you disconnect the 2 cables from the media reciever and the panel and then try to turn on the panel it should light with red and green squares for a few seconds but will turn off as it needs the media reciever to be connected.
Make sure connections are going-audio out from tv to d-tv/cbl in on back of reciever. Then turn on tv and turn reciever input to d-tv/cbl and make sure the input mode is on auto. Hope this helps you.
Sounds like you are exceeding the maximum power output of the receiver. Try disconnecting some speakers (and switch to A-only mode if your model has multi-zone) and see if that makes a difference.
