Samsung PN60E530A3FXZA replace the power broad and still no picture or sound?

Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Kenmore dryer 79690272900

This is too broad a question. Does the dryer light go out when you press the button? It should, but the switch could still be bad. Is the motor receiving power? If yes, replace the motor. Is the belt in place so that the belt switch is working? Test the belt-switch with meter. Lastly, is the main control (logic) board still functioning? Consider this last.

No power

maybe you have already done this, but remember that many laptops require that you remove the battery for about 30 sec. as well as disconnect the AC power to reset them.
Always try this when everything seems completely dead.

I have an eMachines T2200 The power supply started making noise and I shut the system off. The next time I tried to boot up nothing happens. I replaced the power suppy and when I turn it on the cd and dvd...

I would check to see if power is getting to your hard drive, Make sure the white molex's are plugged in.

E-Machines are, unfortunately the worst machines out there. They're up there with Compaq.
You're not going to like what I say but I'd urge you to buy a new one. Chances are it will take an arm and a
leg to fix what your using and for a little bit more money you can have a really nice one for 500 dollars
or less.

When I turn the monitor on the switch goes from blue to orange and the screen is black

It can be that it is not getting the video signal from your PC, you should try it with another PC and also check the video cable, or it can be failure in the logic board where the video cable is plugged in, or in the power suppy/inverter board. Please poat back what you find before taking the montior apart.

Capacitors kit: he can make you a set of caps for you.
Please post back what you find.

Power went off and on and now I can't get the MX850 to start.

If you can move the printhead to the center, try removing the inks and the printhead. Try to turn on with printhead removed, if power comes on you need a new printhead, if it doesn't come on the power supply or main logic board is bad.

Irrespective of being a PC or a Mac the computer system behavior and consistency are dependent upon certain factors. These factors are broadly divided into software factors, hardware factors and the surroundings.
The common software factors leading to a logical failure are:
i.) System files responsible for handling control to the operating system missing or corrupt
ii.) Unsigned drivers or drivers trying to access read only system area
iii.) Operating system files corruption due to incomplete automatic update, malicious software
The common hardware factors leading to a physical failure are:
i.) Problems related to mainboard in terms of the chipset or connector, power supply issue like incompetent power supply to run the hardware setup
ii.) Problems related to hard drive itself or the data or power cables
iii.) Improper setup of hard drive cooler fans (if any)
The common surrounding factors leading to data loss are:
i.) Heat dissipation issues related to closed or poorly ventilated surroundings like in a basement or store
ii.) Moist surroundings leading to the formation of thick dust layers and thus increasing heat
iii.) Direct sunlight leading to extra heat and thus hardware failure
We should logically negate these scenarios so that we can narrow down to the root cause of the problem and take corrective measures.
In case we find that the data loss is due to any logical failure, we can use data recovery software as they are programmed to meet the challenges due to all kind of logical crashes. They scan through the file system, locate all the files which are marked as deleted and are distributed as fragments across the partition, logically rearrange them as per the file system information and then recover them. The data recovery software are indispensable in cases like file system corruption, hard drive formatting operating
system corruption, accidental file deletion or malicious software like virus, spyware etc. We can perform a ‘Do It Yourself’ data recovery using these utilities as they are self descriptive and User friendly.
We need to install the data recovery software on another hard drive which is bootable. We can also use a different working system preferably using the same operating system platform as for MS Windows. Then, we can attach our hard drive to the same for scanning. For attaching the hard drive we nowadays use USB 2.0 Hi Speed or IEEE 1394/Firewire Cables, Attachments or Enclosures. The same can be achieved by a Master and Slave setup that requires hard drive jumper operations and thus is a little complex. We should avoid any other jumper operations as of the mainboard as they may lead to unstable system behavior based on BIOS settings.
We should always save the recovered data on a healthy hard drive.
In case of data loss due to hardware failure where the hard drive is either not getting powered or can not be recognized by the BIOS, we need to go for hard drive recovery service. The data recovery service is personalized help, delivered by data recovery experts. Such experts can extract your data in all possible scenarios of physical data loss.

GT5014 won't boot

Generally this means there is a problem with the power suppy as it is not giving a correct voltage to the motherboard to start the computer. check your fans on the power supply, make sure they start when you try to start the computer . A power suppy may be purchased and installed fairly easy. and you should spend no more than 50 dollars on the parts.
