PC Monitor flashes amber light

By cricket4b ·
A 1 yr old HP monitor suddenly went "bad". On booting up my HP133 the monitor started flashing it's indicator light amber. No screen image. Calling a tech support, they recommended a new monitor. Bought one on sale, KDS, plugged in and worked fine. Problem solved? No way. 1 month later, same reaction. I brought the new monitor over to a tech person and had it evaluated. Fried! Sent it back to the company and they replaced it for free. (Good Company support) Meanwhile, back at the ranch: a very old monitor was in place while waiting for the new replacement. 1 week later, same flashing amber light, no screen image. The video is embedded in the MB and uses system RAM. I tried disabling it and installing new video card without success. I have the new monitor and am leary of installing it until I find the culprit. (Now using another old monitor and have not had further problems) Suggestions?

PC Monitor flashes amber light

I've supported PC's for 10 years and seen a few flaky problems, nothing quite like that. Here's what I can tell you.
1. First thing to look at is power. Are you useing a GOOD surge suppresor? If not, get one. Not a $10 dollar one. If you can get a cheap UPS, even better. It will monitor power and give you reports on power changes. Also, is anything happening near the PC when it fries? AC, vacumn, space heater or another big power draw on the same circuit can cause problems.
2. Change sockets,use power on another circuit. Or, just move the PC. I've seen power cables in the wall affect screen performance.
3. What's near the PC. Having a motor or some other piece of electrical equipment near the monitor can affect the screen.
4. If you've followed all of the above,(or do this first), find out the pin voltage that is supposed to come from the pins on the video port. I can't remember off the top of my head, but most are + or - 5 to 12 volts. Get a VOM meter and test the votage. I think one of these should tell tou something. As an aside, I bought a KDS monitor last year and it was bad out of the box. They can be a problem sometimes.
Hope this helps.

It has to be environmental. The most likely cause is power. A good ups will probably solve the problem. The other thing to look at is other electrical devices in the area, refridgerator, air conditioner on the other side of the wall, etc. Also, is the monitor in direct sunlight? Hanging plants above it? I heard of one case similar where a guy had a plant above monitor, slowly dripped water on it. Fried 3 or 4 monitors in a row. The key is looking toward your environment. What around the monitor could cause it to fry?
Good luck!

Hi I ve been into the design of monitors since 1978 and yes in the early days of multiscan monitors which is what a pc monitor is they could be damaged by inputing the wrong signal frequency, but that is all in the past the modern monitor will just go into power down or show a text box saying something like "signal out of range" with no ill effects. I guess you were unlucky with both monitors the HP for failing at 1 year and yes KDS are not the best but this still should not have failed so quickly. The surge arresters or ups are a waste of money if you live in an area like a town or city where the power will be good this is in the UK if you live at the end of a long supply ie the country side then yes it might help. Video recorders and TV sets suffer just as much if not more from power surges/spikes. So use the new monitor after all while not using it the warranty is ticking away.

Hope this helps

I live in a small country town in MI and the power is not too bad, but brown outs do occur. Thanks for your answer.
