Most of the time it will need service (output transistors and resistors) This is a job for a electronic service tech. Estimate would be $100- $130

The "PROTECT" and "PUSH POWER" messages will flash alternately when the protective device of the amplifier has been activated because a strong signal was input, or if there is a short-circuit detected. Press the POWER button on the unit to turn off the system, and check the following items after "STANDBY" disappears.

1) Are the + and - speaker cords short-circuited?
2) Are you using only the specified speakers?.
3) Is anything blocking the ventilation holes of the system?

You may also refer to the following link for additional troubleshooting steps.

Only one (out of four total) HDMI input is working on my set.

The HDMI switcher IC chips in TVs can be damaged but lighting hits near you house even if the power is protected with a surge protector. The damaging power comes in through the HDMI port and blows the chip out and it can affect just one port or multiple HDMI ports. Your best bet would be to just get a cheap HDMI switcher and use the one working port. The repair on the TV would require placing the control board and would run from $75-150 for parts plus the labor to install it.

My STR-DE925 reciever isn't giving me any sound. When i turn it on everything works like normal, kicks on, and there is a click; but after a few seconds the display switches from whatever input it was on...

check speaker connections.sounds like the system is trying to stop some thing more serious happening by shutting itself down.a pain yes but saves blowing something up.if no luck,then definately send in for repair

I found an old Sansui 9090 receiver that I'm told is a great receiver. It looks like it's still new but it hasn't been used in several years. I have one speaker plugged into the input, and it is...

Speakers don't plug into inputs. Check your work.

Try powering it up with nothing attached, then proceed to attach things (like a speaker to the speaker terminals) and see what happens.

LG 37in HD LCD tv not responding to any pressed buttons.

Based on your description, it appears that you have main board issues with your unit since your controls do not work and some inputs are NG.

Beeping F11

F11  is a keypad short. This was actually a simple fix when I got into it. Take off the top rear panel. You will need a drill driver or #2 square drive. Once inside: the EOC is held in by 4 screws. Remove those and pull out the EOC. 

My diagnosis on the problem is this: The keypad connection to the EOC is the thin plastic serial connector on the top of the unit, looping to the back. What I figure is that this plastic must have the  tendency to warp under the influence of heat and  thus reduces the good connection to the serial input on the EOC. There is a black plastic connection protector on the input side of the serial connector at the EOC. Gently pull this off and pull the serial connector out and give it a good cleaning. Place the serial connector back in the receiver and replace the connection protector back on. ( tricky.  if you have ever built a model or soldered anything you will be fine.)

The serial connection will need some pressure on it  to make a good connection if it is warped. My solution to this was to run a plastic cable tie thru the small holes in the top of the EOC. tighten the cable tie over the serial connector, pressing it to the top of the EOC. This gives it a good pressure on the input pins in the connection input. 

Now plug the unit back in. You should have full function of the keypad. If not, it may be another issue with the keypad or EOC.  This was a solution I happened to stumble on and it may not work for everyone but giving it a shot means you might save 170 dollars in parts not including the labor.

Will not turn on

Does the set make any sounds. DOes the front green led light or flash when you try to turn it on.. if not then it could be as simple as a fuse, if it does flash then it can be many problems
