5 minute 'electrical interference' HP pavilion f1803 monitor

The monitor was recently swapped with a different one temporarily. When the reconnected monitor is first powered up there is what seems to be electrical interference (the screen shakes gently) from a nearby source (like a fan), only not as powerful. Even thought everything was put back where it was before, why would this happen? After about 5 minutes (or less), this stops. If it were true electrical interference, wouldn't it continue?

What can I try?

Does this mean the monitor is on its way out?

Timer runs constantly. Runs cycle then shuts off and shortly later restaRTS.


Posted under GE 15069 countdown timer.
Unknown if this is new timer that is wired wrong or if load has interference, or existing timer that stopped working.

If new timer, then check wiring: This timer is for single-pole application only and requires neutral wire.
http://waterheatertimer.org/GE-timers-and-manuals.html#15067
Then check for line interference by moving timer to different Load, for example ordinary incandescent light bulb.
Make sure slide switch is set to Timer.
Slide switch works as ordinary on-off switch, so see if slide switch works correctly.

If timer stopped working:
Feel timer if it is warm to touch indicating overload or internal timer short.
Timer is rated for 1/2 HP at 120Volts. Check nameplate on motor for HP.
Check for short in line by temporarily replacing timer with on-off switch, and check wire nut connections.
Move timer to different Load, for example ordinary incandescent light bulb.

If timer has gone bad, then return it to Home Depot and swap for different timer.
If load interference is problem, then buy mechanical spring-type countdown timer like Intermatic FD60

Hp pavilion slimline s3020n PC the computer says no analog signal the problem is all the time cant run the computer at all.i have not tried to fix the problem myself


Does the computer turn ON? (do you hear beeps?, do you see lights on the computer NOT THE MONITOR?, do you hear the fans?, etc...) it could be the monitor, try an other one, it could be the video card, swap it with a known good one ,it could be the VGA cable change it, etc... if the computer is all dead try an other electric outlet.

Good luck!

My monitor does not bring the bios set up and up saying no input signal what are the solution and causes


Check that the "data" cable is tightly-connected at both ends (monitor & video-card).

Try connecting the monitor to a different desktop/laptop computer, to see if the monitor works at all.

Try a different "data" cable between the monitor and the video-card;
obviously, your monitor's "power" cord is working, and thus, there's no need to swap that cable.

Try connecting a different monitor to your computer, to see if your video-card is transmitting any signals.

Temporarily swap-in a different video-card, to see if the video-card is the problem.

If all else fails, take the computer to a technician at a computer-store.

I have an HP Pavilion dv9000 laptop and I use a a second monitor connected via the vga output. A few days ago the second monitor turned blue and after a few minutes returned to normal. This problem is...


It definitely sounds like a problem with your video chip.
Is your display blue as well on your laptop screen itself?
I would try changing the display resolution for your external monitor to a lower resolution and see if this makes any difference.
If this helps in any way, it could be a monitor profile issue reporting incorrect settings to your system.

If your display is fine on your laptop screen, then i would suspect a failing video chip.
there isnt much that can be done for this short of replacing the motherboard. There are several service centers that will do component level replacement on a motherboard, and i have done a number of video chip replacements. component replacement is cheaper, but either way it wont be a quick or inexpensive fix.

hp did have a partial recall on these and several other DVxxxx but i believe that has expired quite a time back.

i dug out the link.

I have a 500GB WD My DVR Expander that is connected via an eSATA cable to my Scientific Atlantic Explorer 8300HDC DVR. It was working great for several months, but recently my recordings are bad. The video...


What happens if you move the DVR off your Sony TV and put it onto your wife's TV (swap DVRs). Does the problem follow the DVR?

If it does, then you are looking at something common with the DVR, since the expander appears to work just fine on another dvr. If it problem doesn't follow the DVR when swapped, you may be looking at a ground loop issue.

Ground Loops occur when different devices are plugged in at different points. Ideally, everything should be plugged into the same power strip, or wall outlet. But, when things are plugged into different points, noise can pop up due to the difference of electrical potential on the grounds of the equipment, and even the neutral conductors. This can occur even when using an extension cord that is plugged into the same strip. Also try using a different power strip temporarily to see if that improves things as well.

Computer monitor is white


What do you mean, white screen?
It just went blank after a few minutes of use?

Anyway, you've already eliminated the monitor as the surce of this problem, so it can now be either the cable from your monitor to your PC or your graphics card. I suggest you try another monitor, and if that doesn't work, find someone to temporarily insert another graphics card into the system.

One of these should fix the problem,
Yannick.

I started my HP computer today and it starting beeping, the tower and monitor have power to them, but the display isn't showing up on the monitor, it's just black


You need to open the tower and reset the memory sticks still if you get those beeps then try those memory stick one by one or swap the memory stick

Display dims


My HP laptop monitor would go very dark (sometimes still legible) and it did it infrequently. The problem got worse and I could temporarily fix it by flicking the monitor off botton (i.e. the thing that sticks out to turn the monitor off when you close it). Ultimately, I had to replace the inverter. It was simple (once I found how to take it apart online) to replace the inverter and it fixed the monitor problem. This is after a computer technition told me that I needed a new bulb or for a little more he could get me a new monitor. Maybe there are some good computer repair guys, but I am now leary of them.
