Re: no red color in monitor that is a hp

Just sharing this, hope it helps.

Are you missing also green color? If red color only, since it is a CRT type, right? Common fault could be video card. Reseat or retighten the connector plug. Some could be settings.

If not could be cable problem or cold solder. Other than that is the circuitry inside is at fault, it could be the transistor controlling the red gun is at fault or some other component.

I suggest to test the monitor unto another computer to isolate first if the monitor is at fault or the CPU unit. If monitor, you may consider buying a new monitor if repairing is more costly than having a new one.

Power and unplug the monitor and tower. Reseat the monitor plug in to the tower and tighten down.Plug in power cords for both tower and monitor.Reboot computer! If this does not work possible video card failure. (good question)

Hp monitor flashes solid colors

Hi there, the mode the unit is in is like self test. Try first to disconnect vga cable from pc and see if the there is notification "no signal" poping -up to see if the problem is not graphics. Anyway you can try to disconnect power cord from monitor and wait a while then try again power it on. If all this doesnt help it will be more then good advice to RMA it if still in warranty. Tnx

My hp vs 15 displays vertical color stripes that alternate different colors wether its hooked up tp computer or not what is wrong, is it junk

It may sound strange but be absolutely sure the cable is plugged into the monitor. Adapter on the computer. The serial adapter on the back looks just like video. Video actually has a faintly noticeable monitor icon rigtht next to it. Plugging into a serial can eventually blow out your monitor. Also, a.badcable can do the same thing. And if you have messed up the monitor's settings you will see the same

Press the menu button on your monitor, then use the controls on the monitor to select something like color balance and turn up the red.

Mymonitor is black and the on button from the monitor is green and is flashing

i havent seen this question asked, and believe me i have searched. i have compaq presario, windows xp media edition 2005, 64 amd processor, model # SR2017CL, with HP 1703 17" monitor. Prob-put computer in hibernate mode other evening, without turning it off. when i woke up, screen had diagonal lines going across it. i rebooted, well manually restarted, since comp would not respond.
Message comes up white with black writing, essentially, prob with active desktop, restore or turn off. i tried to turn off and screen went back to diag. lines. looks like the horizontal hold of a tv screen is asque. tried adjusting monitor to no avail.
tried a few more times, was fine for a few mins then went to same thing. now when i turn monitor on it blinks red, blue, and so on.
just whole screen that color. so i am at the point where i dont
know if its the comp or the monitor. (i am quite a newby)
ty for any help you can give
