Can you repair main samsung board BN94-07278B


Generally it's not easy to repar a main board. No way to tell fron a Q&A forum. The only way is to check each one idividually, evaluate the damage and the possibility of repair vs replacing the board or disposign of it as irreparable.
So, take your computers to a repair service and ask for the dignostics,
By the way, looks that your "surge supressor" was not working. Get yourself a good one

Computer will not boot or anything


Does it have power? Have you tried hitting the F8 KEY repeatedly after the initial windows screen starts? Do any of the pc's lights come on (hard drive usage,lan,cap lock,num lock, etc)? If you have absolutely no power try another outlet, if your connected to a surge protector see if the surge protector reset has tripped (found on medium to expensive protectors - if you hve a inexpensive one you probably wont have a a reset on it) try to plug something else into the outlet like a lamp, if you have no power check your household circuit protector and reset the fuse, but of course be leery. If something tripped the circuit something isnt right, indicating a power surge. Storms in your area or construction nearby?

I have a Power Supply OKIA 550W black, and i whant to know what kind of sensor thermisor I have to use for reparation. Because it burned and I cant read it.


If burned out, it is most likely a MOV surge supressor. Since most PC power supplies are 120/240 vac rated, a MOV of 275 volts or greater would work. The exact values are not critical, as it is for line surge supression.

A power surge knocked out power to house. tv will not turn on but click twice when button is pushed, but no picture.


There may be some fuses internal to the TV. You must be confident about you eletronic abilities. A tech can tell you more. Household insurance or your local power company can aid you in the cost of repar and/ or replacement.

That is why you are seeing more power protection. These units require more protection than a computer. After all they cstt morel

Gateway 507GR Wont Power-On after a power surge.  Had slight hissing noise in the Bestec power supply, replaced it, and it still will not always power-on. If I switch the a/c power on/off really fast...


Sounds to me the like soft on/off power switching in power supply itself is not working. Try another supply or if u have a tester try that. Wont be the motherboard or nothing at all would be happening.
Hope this helps

My compaq sr1020nx wont turn on. green lite on power supply is blinking. power company turned off power and when it came back on this is what i found. computer was hooked up to a surge protector.


Surge protectors blow with excesive power not with drop and return spikes, and that doesnt still promise that it will not kill power supplies and motherboards. I would suggest a new power supply as they are all standard then see if it works. If not your motherboard maybe shot if it was on while it happened.

After power surge my tv (toshiba 52') will not power on


after a power surge if you dont have in on a surge protector it probably fried the main board in the tv so it wont work anymore..woudl probably be cheaper to buy a new tv than to try to repair the one you have now
