Monitor does not work

I had that problem awhile ago, but the issue was a loose connection.

If you test your PC with another good working monitor/cable and still receive a no signal message, then the problem is with your PC.
The solution could be as simple as dust inside the unit interfering with the signal, and needs to be blown out, or try removing the power cord and hold-in the 'on button' for about 30 seconds to a minute; then reconnect the power cord and turn it back on.

Other solutions: open up your PC and take out and put back in the video card; remove the ram memory strips, rub the end gold colored strips on a clean cloth and put them back; or maybe you have a bad video card.

Check to be sure your monitor connection needles are seated properly. Is mouse wireless or connected to back of tower?

it is something about your monitor not connecting well with pc, check graphics card

Try another monitor to verify the Graphics Card, if you have a graphics card, then another monitor cable. check for bent pins in the connectors, eliminate the hardware by changing each component/cable one by one. It may be the Graphics Card/Adapter is gone. Clean the inside of machine, overheating due to dust will cook components, GPU's get quite hot. Try some Electronic Contact cleaner spray on the Graphics Card connections, if applicable. Unplug before reseating the Graphics Card or cleaning, take precautions in ESD before handling a Component. If your Graphics is integrated, you can purchase a aftermarket PCIe x16 Graphics Card quite reasonably, : http://www.google.com/webhp?source=search_app#q=ati+amd+pcie+x16+graphics+card&hl=en&sa=X&tbs=vw:l,p_ord:p&tbm=shop&ei=ze05Uf25KJDO9ASIyYHYDw&ved=0CF8Quw0oAg&bav=on.2,or.r_qf.&bvm=bv.43287494,d.eWU&fp=bc2048b0dd90d6d4&biw=854&bih=580

Make sure there is no dust that will make a dirty filter.
Check the refrigerant and make sure the fan is still good.

Dirt and dust prevent a good air flow around the coils.
Once the ice starts it acts as a blanket making it easier to freeze up.

Run it on fan mode to melt the ice.
Make sure it has somewhere to drain.
Clean out / vaccum / blow out the coils inside and outside.
Replace air filter.
Clean and wipe down everything.
Check refrigerant level.

If this does not work take it to a repair shop.

Good luck

Appears to be that the power is not getting to the temperature controllers. Suspect a problem in the wiring between the wall outlet (if not the wall outlet) to the temperature controllers. Look for broken plug at end of cord or a break in the cord between the plug and the controller. Last, you may have to look at the connections inside the temperature controller the power cord goes to in order to see if there is something loose inside. But do this with the blanket unplugged.

So it sounds like it's heat-related. Does that video card use a cooling fan? Is the fan still working? Maybe the PC needs cleaning out, you might be amazed at the amount of dust that can build up inside the case.

If you're cleaning be careful not to dislodge anything, or create electrostatic zaps. Leave the power cord plugged in to provide an earth, but turn off the power point. A new 2-inch paintbrush is good for brushing dust out.

If the card has a fan it could be clogged with dust, or may have died altogether. Find someone who knows how to clean or replace it, if that is the case.

I am trying something now as I was told F2 requires you to check the blanket for wear and tear and plug it back in. 3 times doing this should be sufficient. If it still reads F2 it's "gone" Ours is new so it shouldn't be "gone" but here's what I found...Where the plug goes into the blanket there are 4 holes for 4 silver pins. I noticed the 3rd pin was a bit lower than the other 3. It will not move up with pliers so don't force it just return it. check there

I am sure that donster74, info will work in your problems , all you have to do is connect and refixed all the conenction from the power outlet to you computer. the computer should have power or else the power supply got wrong. verify the outlet if have power on it.

Any problem arising the solution please tell me sothat i can tell you more troubleshooting on it. do not rate me if still problem on it.
