Tannoy precision 8D distortion and cuts out

left channel control pot dirty most likely. is there a slider type pot on channel? this would have to be cleaned with dustoff spray.

if your truck has bose the you probably blew the bose amp and will need to bypass it now to prevent speakers from making noise.

Hiya, i assume for now that you mean the 16dip switch. If i remember correctly it is solder directly to board (could be wrong). If you are comfortable with doing this, it will need to be opened and resoldered probably for dry joints. If not then suggest hunting out a friend with some solder experience. A word of caution though, shorting out solder tracks etc could result in damage so only do it if you are comfortable. If the dry joints are really bad (sound like they are) you should be able to see them clearly and resolder (look for not so bright and shiny solder that looks cracked. Magnifier helps)

Hope that helps

One of 2 things is going on.

First, the servo mounted in the driver may be going bad or is picking up some noise.

Second, Something in the amp section is going bad, hard to pinpoint the exact problem.

you say that it plays, so I tend to think it is the driver mounted servo unit.

If it is within the warranty time, take the unit back to the retailer you purchased it from, if not contact Velodyne for repair.

Go to this site you need a flyback its the only onethey sell for an RCA number 259296 cost less than 50.00 and they provide free tech support so you can do the repair yourself which takes about a half hour. a repair shop will charge abut 400 to replace the flyback. heres the link

you have a problem in output stage and output ic need to check or replace.

That crackling noise has nothing to do with the television and everything to do with your antenna. It is merely signal breakdown, when you get signal interference with analogue tv you get snow, with digital you get little squares on the screen and/or sound breaking and cutting in and out, get a licensed antenna repairer to come out check your signal strength as you may need a booster or your antenna could just be a few degrees off....

Yea, now its time to replace it! the magnetic effect is weaken which makes the very bass low frequency sound to be distorted! You should re engergise the magnet of the subwoofer or should buy the new!

too much refresh rate! set it to 60 hz only! you're over-stressing major components on your monitor!

Sounds as though you have a faulty monitor. Give Acer a call and see if they will change it. They usually offer a 3 year warranty with their screens.
