Re: no video on my dell latitiude d800
You could have a faulty inverter, To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions. Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp. Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case. The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills. Check out www.lcdparts.net for parts, repair service and DIY info.

Does it freeze when you play a DvD on the system? if not, Video Memory is probably not the problem. I would say your problem is probably the streaming or downloading from the site you are watching the video from. Your line speed might not be high enough (for example, AT&T sells different line speeds and the lower the speed, the slower the download). How much main memory do you have? That might be a factor too. I would say you should at least have 1 to 2GB of memory.
You could have a bad peice of memory or a bad memory slot. Pull the memory out and try one peice at a time in each of the two slots. If you only have 1 peice you will need to either borrow a peice of the same memory or buy it. You also could have a shorted battery so pull the battery out if the ram is ok and try to boot. Another idea is the cd rom may have a problem so pull it if the ram and battery are ok. After doing all this if the system will still not boot the motherboard must have a short and needs replacement. This model also had an issue with the power board where the power button is. The connector on the motherboard was poorly designed and very sloppy. Over time it gets worn and causes a similar issue. The temporary cure is to press very hard on the power button to see if it will boot and then leave it running. You can also put pressure on the underneath side around the docking port and press the power button. This issue however requires a new motherboard. The M60 is almost the same as the D800 infact most parts are interchangeable. You could switch out the motherboard to a D800. I refurbish the D600 AND D800'S daily so I am fimilar to this issue. Let me know how you make out. Phil email@example.com
Turn of all power then unplug battery, disc drive, and make sure there is NO POWER on at all. Now take the laptop and turn it over and remove both or if you only have one memory Modules, If you only have one try it in the other memory slot and try to reboot laptop. I you have two module remove both and only replace one and see if it boot up normal after that, I think that may fix your problems, I have seen sometimes the memory module gets loose and will cause a freeze up. Hope that solves your problem
