If one side of the amp is heating up there are two easy reasons....1...the speaker wires are shorted together....2...the amp is faulty. Bryston has a 20 year warranty from the factory...have your serial number handy and contact them. If it is an older amp like a 2-3-4-6B then it may be out of warranty. Older amps all have age related issues. Even Brystons. I have repaired and rebuilt many and they are definitely NOT a do it yourself amp. Hopefully yours is still under warranty and for a small fee you can get Bryston to repair it for you and be enjoying it again for years to come. Best I can tell you without seeing the amp. Good luck and shout me back....Rob

Is there sound coming from the amplifer?
It could be that the biasing has gone or the output transistors are going into thermal runaway.

Which Bryston amplifier do you have?

Let me know.

In cooling system the engine turns overheat in five minutes it is possible that the thermostat and thermostat valve and thermoswitch is the problem?

Thermostat most likely the culprit. Till fixed open the windows and run your heater full blast.

Could also be a bad water pump, clogged radiator internally, outer debris clogging radiator fins.

Runs for 4 minutes then overheats and stops

Check cooling fins on cylinder head are clean, clean filter, clean exhaust, all these things help disperse heat from the engine. Make sure fuel/oil mixture is correct.

I have the PARTS DIAGRAM if you need it. send your email and i will pass it on.

Husqvarna weedeater overheating after unclogging exhaust

Were any of the cooling fins damaged? This is a totally air cooled unit, air flow and fins are required to keep the unit cool. Make sure the fins on the cylinder and head are clean, the blades on the coil are clean, also check the spark plug to make sure it is the recommended plug, is the muffler clear? check airfliter and always use pre-packaged fuels.
Only other cause would be the carb has been set to lean, but I doubt that.

Craftsman dy4500 engine overheats

the first thing to check if any air cooled engine is overheating is to take the top cover off the engine mice like to build nests under the cover this blocks off air flow to the engine the fins on the flywheel draw the air and send it threw the fins around the cylinder and heads if so clean it all out and after using it and it cools down place drier sheets around the engine and wiring also spreed them out around a storage shed or garage thet don't like them

Ggateway ms2274 shutting down wont start up

onehugo, has the inside of the laptop been cleaned out?

The Gateway MS2274, is also known as part of the Gateway NV52 series of Notebook PC's.

Look on the bottom of the laptop, and post the Model Number.
(Examples, NV5207U, NV5211U, NV5212U, and so on)

(Clicking on Product Views, then on the different product views given, will show you the ms2274 is part of the NV52 series )

The laptop uses the same cooling system as most laptops.

1) Cooling Tube:

Slightly flattened copper tube, sealed on both ends, and filled with Nitrogen.

At one end of the Cooling Tube there are two small metal plates. One plate sits on top of the Processor. The other plate sits on top of the graphics chipset.

At the other end of the Cooling Tube a Heatsink is mounted.

2) Heatsink:
For this series it is a rectangular finned object. Small strip of metal with Tall, Thin fins protruding from it.

3) Fan Assembly:
Fan set inside a backwards D shaped shroud. (Surrounding cage)

The Fan Assembly draws air up from the bottom, then exhausts the heated air out of the side of the laptop.


The two small metal plates absorb heat from the Processor, and graphics chipset.
The heat is then absorbed by the Cooling Tube.

The Cooling Tube transfers the heat along it, up to the Heatsink
The Heatsink absorbs the heat, then radiates it away with the Tall, Thin fins.

Air flow from the Fan Assembly, helps carry heat away from the fins of the Heatsink.

This is an up close example of the cooling system used, on the Gateway NV52 series of Notebook PC's,

Scroll the page down to the photos.

The bottom photo shows the cooling system, as it looks removed from the laptop, and the side that contacts the Processor, and graphics chipset.

Here I am able to show you the metal plate surface, that contacts the Processor, and graphics chipset.
With this design there is only one large metal plate to do both jobs, instead of two small separate metal plates.

Coming from the end of the copper Cooling Tube, and going to the Left;

1) You will see a small square, covered partway with a gray Thermal Paste.
(Thermal Paste makes a triangle shape)

This pad sits on top of the Processor/

2) Coming to the left a little further you will see a rectangular copper pad, with gray Thermal Paste smeared on it. This pad sits on top of the graphics chipset.

[ The Processor and graphics chipset, are the two hardware components inside a computer, that give off the most heat ]

Also here you will see at the side of the (Black) Fan Assemblies shroud, is the finned Heatsink.

Point of this long 'dissertation'?

Want you to see the cooling system, and especially the fins of the Heatsink.

Air is drawn up by that fan, and pushed through the fins of the Heatsink.

ANYTHING the fan draws up with the air, is pushed through the fins of the Heatsink

Dust, dirt, hair, food crumbs, lint, name it, is drawn in.

This coats the fan blades, fan's center hub, and surrounding cage. (Shroud)
Also clogs the fins of the Heatsink.

This drops the cooling capacity of the cooling system, tremendously.

The Processor, and graphics chipset overheats.

When a Processor overheats it turns off. (BIOS turns it off)
No Processor operating, no computer.

After a few times of this error codes are logged in. BIOS won't turn the Processor on, until the problem is fixed, and error codes are cleared.

Solution is to clean the inside of the laptop out.

Laptop partially disassembled;
Use an ESD wrist strap, ($3 to $6), and connect it's alligator clip to a good ground source.

Use compressed air for computers, a soft small brush, (Makeup brush?). and Q-tips.

No sir/ma'am.
Using compressed air at the Fan Assemblies opening, at the bottom of the laptop, (Air Intake Duct) WILL NOT DO THE JOB CORRECTLY.

It will just shove the gunk further into the fins of the Heatsink.

Use compressed air at the side of the laptop, and the exhaust port?



You see I mentioned Thermal Paste.

The bottom of the two pads on the large metal plate, on the Cooling Tube, (Whew!), is not perfectly smooth.

Neither is the top of the Processor, and graphics chipset.

A magnified view would show imperfections.
'Pitholes, Valleys, and Hills'.

When the two surfaces are mated together, (Pads on top of Processor, and graphics chipset), they create Air Pockets.

Air is an Insulator. Not a Conductor.

Thermal paste fills these imperfections, and is an excellent Conductor of heat. Transfers the heat well.

After time the Thermal Paste dries up. Caused by age, and the heat of the Processor, and graphics chipset.

Fresh, new Thermal Paste should be used.

The top of the Processor, and graphics chipset, plus the bottom of those two pads on the metal plates, should be cleaned THOROUGHLY!

Then fresh, new thermal paste is PROPERLY applied.

Software problem? Windows is messing up?


You stated the laptop is shutting off, BEFORE the operating system is started.

[ You press the Power On button. This is tun presses against a momentary contact switch. The Power On switch.

The first chipset to receive power is the BIOS chipset.

BIOS looks to see what devices are connected, does a Ram Memory count, turns the Processor on, then hands the computer over to the O/S.

The Processor isn't turning on, or isn't staying on ]

I can post links to the NV53 series of Notebook PC's, for a Service Manual, and pictorial guide, for disassembly.
With this info you can crossover easily to your NV52 series.

If you wish to clean out the inside of your laptop yourself.

There is ALSO other needed information I will state along with them.

Post back in a Comment.

Open unit up and clean dust and debris off heatsink fins. Outer case opens much like a clamshell once screw are removed from bottom. Plastic seam and end pieces pop out with flat screwdriver (carefully). Inner unit can be removed and opened easily after this. Once cleaned and reassembled, try to keep unit in clean, cool, smoke-free place with good air circulation for best life and performance.

the AC puts an extra load on the cooling system in your car. a short descriptive reason is that the AC condensor is in front of the radiator therefore the heat it emits is dumped into the radiator cooling fins. so when your car overheats when the AC is on and dont overheat when its off its an early warning sign that something in your engine cooling system is going bad. such as thermastat or waterpump. or it could mean your radiator need flushing from the inside and the fins could be clogged with dirt and bugs that get past the grille. try cleaning the cooling system fins first the ac condensor and radiator see if water will sprat through the grill into the fan with your water hose. then if cleaning check all the other items i mentioned good luck james
