No Signal as a message on your Display indicates a loose cable in most cases. With a flat panel this is usually where the cable connects as that spot on the flat panel is often difficult to access. It is best to remove the cable and reattach. Then use a slot screwdriver to tighten the thumb screws down snuggly. Do not over tighten when using a screwdriver. The same is true at the back of your computer. Remove and reattach the cable and tighten down with a screw driver. Your cable should be attaching to the same color connectors at the back of the computer and the back of the Display panel. You can try swithing over to the other set of connectors, when two connectors are present.
Should this not solve your problem or you have already done this then you have a loose display adapter card in a slot inside your computer. To know if you have a display adapter card and not a chip on the motherboard, look at the back of the computer. If the display cable connects vertically along the lines of the cabinet nearby the mouse, keyboard and USB ports, then you have an onboard display adapter and this cannot be loose as it is a chip soldered onto the motherboard.
If however, you have the cable connected in a horizontal position in the bottom half of the back your are using an add in device card that is physically inserted into a slot.
In this situation, you need to remove the side panel, and or the cover. While looking at the inside of your computer you will see a PCB board in a slot and the display cable connected to the outside end. Remove the cable, look where the display card is inserted. At the end at the cabinet side there should be a screw holding the card into place. Remove this screw. Then at the far right end of the display car there may be a latch near the motherboard surface that is or isn't latched correctly and this loose connection of the card in the slot will be sufficient to cause a Signal Loss error message. Release the latch if needed and remove the display card. Be careful about static electricity discharge. Just try not to move around a lot while doing this. Once removed, just reinsert the card using considerable force to lock the card into place. Push firmly straight down on the card. Once this is done, reinsert the screw at the cabinet end, reattach the cable and boot up again.
This process you have just gone through will rule out any and all potential loose connections in the path from the motherboard to the display.If you still get a Signal Loss error message, you may have the cable connected to the wrong plugs. Often there are two, two on the display adapter, whether a card or onboard. One would be Blue the other White. The same is often true at the back of the Flat Panel. You may have two connectors there as well. One Blue and one White. If the cable is connected to both Whites switch to both Blue. Normally, the cable should match the color connector on both ends it is attaching to. On the back of your display adapter you may have two white plugs. In this case it is designed to allow you to use two monitors. Try switching the cable to the other plug an so on.
