Lights everything seems to be on, but no sound

Go though your menu on the reciever, Look for the speaker functions for your front end rear speakers ,It was probably turned off. Was it working before you got it from your friend,

Is the audio problem present on all iputs? Your problem could be the power supply or the A/V board. Proper troubleshooting would need to be done to verify which one it is. I would lean towards the A/V board.

This can happen. Lightening causes static charge that can be picked up by speaker wires. It is possible ONE of the amplifiers has failed.
To check, have the room quiet. Turn on the amp. After 5 to 10 seconds there should be a nice solid 'CLICK' from inside the amp. If there is no click, the unit is in safety mode. You will need a service shop.

If headphones work then so does the amplifier. When did this problem start? From what I can find it almost sounds like it thinks you have headphones plugged in, which would disable the speakers.

I take it you have made sure that both the cable to the distortion box from the guitar and the cable to the amp are both good. From the description you give, it sounds like there is no signal getting to the pedal. If the cable is good, then the next likely suspect would be the input jack on the fuzz box. Try wiggling it a little with the guitar cable in place to see if it is loose. Some input jacks are unbelievably cheap and flimsy. A crackling sound (static like) is almost always a bad connection. If it was the output jack, I would think that the guitar signal would come through a least a little bit, but you might want to try wiggling that one, too, if the input jack isn't the culprit.

Another possibility to check is the battery, but this doesn't seem as likely. Some effects units devour batteries, especially units that use 9V batteries. I have a multi effect pedal that kills a 9V in about an hour.

when the computer boots does the screen light up? if it does the first thing you need to try is when you turn the computer on is to option boot. That is done by holding the option key while turning the computer on. after it boots you will see the the hard drive listed on the screen it will be a icon, if there you should be able to boot up. If the computer does not boot and your hard drive is still listed you most likely have a logic board aka mother board issue.

Do you hear a clicking sound when you try and turn it on? If so how many clicks? Also do you have and sound from the unit static or anything?

Hi mdpagan

There are lots of mechanical switch contacts to these old girls. Go about wriggling and tweaking with all the controls and switches on the amp. You may find one of these to be the source of static. These sorts of problems can be sorted out with a squirt of CRC2-26 into the switch or control that is noisy. If it is not this, it may have a leaky capacitor or noisy transistor. the mains switch can produce strange static also when they get a little tired.

I am more than happy to answer any other questions you may have about it, just give me a hoy :) If you are still unsure, or have problems, then before you give a rating for this advice, please get back to me and we can try some more things.
Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.

Returned the durabrand uc-280 to Walmart! Plugged the existing speaker into the correct hole in my new sound card. Problem solved!

Sounds like a hardware problem with the screen. Try switching the video driver temporarily to one of the Microsoft standard drivers (like VGA STANDARD) and check if the problem is any different. If it is, then it is a software driver problem. If the problem is the same, switch the driver back and try this.

These solutions may damage your machine, so do so at your own risk.

Get the machine running normally and then try the following tests, watching for the static on the screen to change (get better, get worse).

- Tap lightly on the sides of the screen unit
- Open and close the screen unit lid to the full extent in both direction
- *Very lightly* twist the base of the computer one way and another - lightly, just enough to put a little pressure on the case
- *Very lightly* twist the screen unit slightly by the corners - lightly, just enough to put a little pressure on the case
- Tap on the corners of the computer's base unit like knocking lightly on a door

If any of these physical tests change the static on the screen significantly, you have hardware troubles. If this is the case, either take it for professional repair, or, at your own risk, try this.

It is very likely that you either have an electrical short or that the ribbon cable connecting the screen to the motherboard has come partially unseated. Find a friend who knows about taking things apart, tell him you think this might be the problem, and ask him or her to help you lovingly disassemble the machine looking for possible hardware problems. Remember to do anything like this with the machine completely unplugged and the battery out, and as a last resort on a machine you need but cannot afford to fix.

Final hint: if tapping or twisting the screen lightly changes the static, you probably have a ribbon cable or other hardware problem *in the screen unit*, while if you have changes in the screen when you knock on the base unit, it is likely where the video signal cabling enters the motherboard.

Good luck.
