Question about Optimus 31-3045 Receiver

1 Answer

Powering Off I was watching a movie and had the sound load and the sound stopped and the unit display said Powering Off. I checked both fuses and they were good. Every time I turn it on it will go to Powering off. Ilooked at the caps and diods and didn't see anything burned.

There is a problem in the audio output circuit. Most likely the output IC(S) went bad. This is a solid state unit and there are no user replaceable parts inside them, Please take this unit into a pro to be diagnoised. Good Luck

How to stop buffering

  • 1 Allow the movie to load completely, or at least halfway, before you start to watch it to stop video buffering.
  • 2 Start the movie and then hit stop until the movie has fully or halfway loaded. As the movie is loading, you should see a yellow or gray line. The line you see will get longer as it loads.
  • 3 Close all windows that you don't need. Having too many windows open will slow the loading process.
  • 4 Resume play once the movie is at least halfway loaded or fully loaded. By this time, you should be able to enjoy the movie without the video buffering or constant starting and stopping.

Sharp comfort touch air conditioner screen doesnt show settings and buttons wont work after cleaning. help its hot!!!!!

Switch off the unit at the isolator or fuse box. Leave off for 10 mins to reset. When powering up again and it still wont work, check your remote control batteries are good. Also confirm you haven't "blanked out" the display. Some controls have a display or LED function which blanks out the display so that the lights are not bright at night time. (For bedrooms so that the light doesn't keep you awake) Also check that you have not pressed a "child lockout button" This will stop anything ..

Fuse keeps blowing out

• Heat could be one of the cause.

As it heats up it consumes more power.

• Another factor is the load ( speakers )

if it is set for 8 ohms and you have 4 ohms in load.

• There could be other factors like the main amp itself

one should check it thoroughly.

My hp 1320 laserjet printer is not powering, i open the printer and check the wiring and i see everything normal. try to check if they are properly fitted and did not see anything improper.

Check the main fuse if the unit blown especially if the unit is totally dead meaning no light on the main panel comes on. You may of had a power surge that blew the fuse. If you find the fuse good and the unit still does'nt power up then you have a power supply problem or something external of the PS is loading it down.

Display driver r300

First try uninstalling the r300 driver from the device manager, then reboot. The machine will find and reinstall the driver automatically. Then adjust the hardware acceleration to the highest setting. If these don't work, then go to or and download a couple of video playing software programs. On second thought, go ahead and down load the video software, it won't hurt anything, all it will do is help. Look under the video section at these sites, and download the video players for the internet. This software aids in watching internet based video.

It sounds more like the motor which moves the laser unit along it's rails is dry and sticking or maybe the rails themselves need a small amount of desintered grease applied. Any good hardware store should help with the grease. Just don't go using automobile type grease, it's far too heavy and will gum the works up. BMW
