I have a Berhinger B115 that works fine for about 20 minutes or longer at about 1/2 power and then shuts off. Wait 10-15 minutes and it will turn back on. I had this issue with an active Mackie speaker years back and it was a protective relay that was failing. Any chance that someone would have a schematic and a place to order parts?

You may have an output transistor gone bad and it is trying to run on one good transistor since they commonly are used in pairs (one positive and one negative). Time for a trip to the shop. Good luck.

well based on your story it seems that your tv when get hot loose some of its contact. i beleive the symptom is cause by a loose solder (cold solder). this is normal especially tv's that are aging. it tends to loose its contact because most of the parts/components of this device are becoming hot when being operated. example of this are resistors, transistors, and ic's(integrated circuits). check the power supply circuits and the horizontal deflection circuits. because these two circuits are responsible for problem you are experiencing. also use a magnifying glass in inspecting the board. based on my experience looking alone without this glass is not enough. you need to magnify it, to see it clearly. but if you are not inclined with this kind of job, better bring it to a qualified technician. one more thing, i dont beleive that the house is related with this problem. otherwise all your equipment that are hooked up in it will do the same problem (on and off). i hope this help you! good luck!

SOURCE: 1986 Yamaha Radian stops running after 20 minutes

Sounds to me like it could be a few things... pretty interesting that it runs and shuts down...sits for a little while then fires back up. Could be something as simple as a bad ground.. maybe it needs cleaned.. if the ground is making very little contact.. the bike would run bad, and because its direct current it has to flow. The metal in the motor frame etc will hold so much DC current.. but *** soon as it load up the bike would stop sparking. Let it sit for a while, DC trickles into the battery through the slight contact, bike fires back up. OR could be bad venting of your fuel tank, or a partial clog at the pet ****.. the first is pretty easy to check, open your fuel cap and start the bike..if it does the same thing then its not a vent problem. One thing that does happen on the Radian, is the reserve fuel screen inside the tank comes loose, and then everything inside the that has built up over the years either partially clogs the pet ****, or the hose, or both. Take the tank off, pull the pet **** off..if it still has two intact tubes with good screens..you probably don't have any junk in your line..but I would pull the line off and blow through it any way... it could be some type of blockage, when the bike sets the fuel seep through, but when it runs it eventually creates a vaccuum that stops the fuel flow. Those are my two first thoughts... good luck!!

That happens when the ballast transformer for the backlight overheat. Backlight or cold cathode light function is responsible for the images that you see in the screen.
Unless you are capable of replacing by yourself the parts with the same value and you have the right tools and skill to do it your own.
Otherwise, I suggest you bring your monitor to a credible technician.. or if the unit is still under warranty you can bring that to their service center..

Ur tv power supply have dying leaking parts call capacitors.The board where the power a/c cord plug into it.That the power supply board.U know basic electronic's,have the tools and know basic soldering?Searches the power supply board for these dying leaking capacitors and replace them,ur tv will power up normal an last.These dying about to be dead are alway bulges up on tops or puff on it tops.These Capacitors must be replaced.Or tries websites like Shopjimy.com,Ebay.com to buy a whole refurbish power board for the replacement.
