| 272334 | 2004-09-14 20:06:00 | I was reading a interesting article from a electronics magazine, were "serviceman" article said a customer bought in a computer repair and said the computer would not go, When the service person turned the computer on, there was nothing on the monitor screen, What would you say was wrong and how common would be the problem? Just interested to see if the "serviceman" is making a big deal out of nothing, I must go to work now I will let you know when I get home tonight. |

Next if that didn't work they may have to look at the monitor powerswitch, now i'm not a monitor tech however i have pulled one apart on more than one occasion . Anyway assume that the monitor is getting power, next step is to ascertain wether there is some other reason within the monitor to not have a picture . . . . . . easyiset method is to plug in a known good monitor instead; if one then has a picture one must assume there is a monitor fault . Another way to test this is to plug the monitor off the suspect system into a running pc if it dont get a pic then the monitor is at fault . Assuming the monitor is ok the tech will then listen to the to the pc to see if other stuff is working when it is started up . . . . . . . . fans, post beep, hdd noise . . . . . then depending on what is or is not working will goto the next step of the diag . AS i said at the beginning there could then be several reasons that there is no pic for example, bad video card, bad ram, bad cpu, bad motherboard, also possibly a bad psu which aint putting out enuf voltage . NOw generally with psu/ram/cpu/vidcard one can ascertain if they're bad by simply swapping them out with known good ones . If all else fails the tech may then start consider the possibility that the motherboard has failed in some way . Now, to do all this the guy/lady needs some very good analytical skills, and quite a bit of practical knowledge about what's likely/possible . As well they need to have onhand suitable swapout components to suit many models of pc . You asked how common the problem would be as a percentage of my work i'd say a blank monitor happens, (for any of those various possibilities that i've already mentioned), maybe 1:20 . |

There isn't enough information to make anything close to an informed diagnosis, and that was after deciphering as much of the post as was possible . |

It basically goes over the charges, and then asks them for their name, contact phone number, and to tell us what is wrong with the PC.....: Please state what is wrong with your PC - ........Everything..................... Always makes me smile :-) |

He forgot to turn the monitor on with the button on the front, common problem for the less experienced . LOL |

| 272342 | 2004-09-15 03:26:00 | Customer couldn't use it during a power cut? After customer returned to house after flood, couldn't restart PC after drying it out with hairdryer? After mice that were living in PC were killed with poison, PC didn't go. Let's not get too serious. robo. |
