Monitor Problem (LG Flatron 795FT Plus)
I have a Flatron 795FT Plus (it's a 17" flat screen (screen not panel) with
a 4 port USB hub on the back of it.) Ok the problem: A while back it started turning off and then coming back on again. Thereis no pattern that I can discern from when it happens. I finally got annoyed enough that I stuck an old monitor on this computer instead and I have been using it (It's horrible, color is bad, hurts my eyes, etc). So I'd like to get my old monitor working again since it's a wonderful display. Recently I upgraded 85% of the hardware in this computer (fuzzy logic insert: at what point does the computer stop being the same computer it was before and become a new computer). That upgrade included a new power supply, so I decided to give the monitor a shot. Since getting behind this computer is a pain I hooked it up to one of my other computers first, and ran it for 4 hours continously. It ran fine, didn't so much as flicker. Well, as you've probably guessed where this is going, I plugged it into this computer and.. nothing. It has power because it would give me the amber on the power button (the "I have no signal, but I do have power"). About 45 seconds later it gave a picture, if only for 20 seconds or so. Anyone have any ideas? The other computer I had it working on is a significantly less powerful machine (p3 550 vs. amd xp 3200), power supply on the working one was most likely a 250 - 300. This one is a 450. Graphics card on the working one is a GeForce2, this one is a radeon 9700pro. I'm trying to use another cable to connect them (it's one of those monitors that has the removable video cables), to see if maybe there is a problem with the cable), but I don't think that is it. Both computers are running same OS (winxp pro), both using default plug and play driver's for the monitor. Would video drivers cause an issue? Monitor drivers and video drivers are different, but do they sometimes conflict? At this point I believe it to be a hardware problem with the monitor, and I would love any suggestions agreeing or disagreeing with that. Thanks for reading the whole thing, I know it was long. ~Chris |

Hi,
From your post I am not sure how technical you are. If you have access to an o'scope try looking at the signals in: a) the moniter plug (Check syncs at right timing + Check levels and sharpness. b) where the moniter lead connects to the pcb. (If there is a dodgy lead you will get an obviously degraded signal. Before I have trouble with the H-Sync losing connection. c) depending on how modern the moniter is any other obvious places. If you come back to this newsgroup with the results of this it should be quite easy to provide you with more precise tests to try. -- Chris |

I think the problem is related more to the video card in the computer that is not working correctly. The card may have come loose in its slot or become slightly mis-aligned in the slot. It's also possible the card is overheating enough to cause the GPU to shut down. The first thing I would do is replace the card, even with a card of lower quality to verify the source of the problem. If the symptom disappars you might then want to ensure the card (or a new card) is adequately cooled during operation. - -- Ron n1zhi -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (GNU/Linux) iD8DBQFBVqPha9fyRcf4bIYRAvUWAJ0VursTcarTNkwxHt9Gjx RxiJMghACgi+gJ wX2kKlc5x7U5Dgic/BjKOZ4= =a8p9 -----END PGP SIGNATURE----- |

I do never looked closely at the model you have. But, for any monitor with
USB ports in the front, you much connect a USB port from the rear of the computer to the monitor USB input. The monitor should have a USB distribution to its front, most likely a small USB hub built in. What I do, is use a USB hub, and keep it forward in a convenient place that gives everything up front. I did something similar to this with a firewire, and a serial port as well. -- Jerry G. ====== "Aamir" wrote in message ... my question was how can i connect my usb devices with monitor instead of cpu (back/front). i want to use the usb provided by the monitor. |

The monitor is just a hub. You need to plug the USB on the computer in to the USB of the monitor. Then you can plug your USB devices into your monitor. |
