Question about Samsung SyncMaster 753S 17" CRT Monitor

1 Answer

Focus on monitor

When there is no input to the monitor the sign "No video input" appears very clearly on the screen. When I put the video in the whole screen seems to go completely out of focus and leaves dark bands of colour horizontally across screen. Samsung SyncMaster (793s)

What your describing is a major video problem, poor color and it is blurr, It would be far cheaper to replace the monitor with a new one.

Right click on the back ground of the computer desktop. If windows XP click properties, if vista click personalise. Now look for settings and move the resolution slider to 1024 X 768. This is the native resolution for this monitor.

If you still have the HZ error, click on advance look for the monitor tab, and make sure it is set to 60Hz

My monitor is on but there does not appear to be any graphics. The CPU is also on too. The monitor keeps showing "check signal cabel"

The ideal way is to crros check to see if the PC or the monitor is the suspected fault. So connect an external monitor to your PC and if this works OK then the PC is cleared. Now check the monitor to confirm. If not there are errors in the signal processing section- the point where the input signal from the PC has to be processed. Possible failure of the input IC.
If however the PC does not output it is failure of the graphics card and must be substituted to confirm and replace.

Text appears fade & sometimes brightness is found high on screen.

Both are signs of a worn out tube. The only thing you can do (apart buying a new monitor) is to increase the focus and acceleration tensions on the tube - by tweaking the corresponding semiadjustable resistors.

Do you have multiple Video cards installed in your computer?

Check the monitor on another computer to verify the Monitor works and so does the cable.

If Monitor works, cable works, and you have 1 video output from your computer, then your Video card is probably no good.

Horizontal line appears on my PC Acer screen and

There are two possibilities: That the monitor is bad, or that the video board is bad.
The easiest way to test is to install a different monitor and see if it does the same.
If it does the same, then it is the video board. If not, it is the monitor.

Desktop at home

do you have a spare monitor?
try and plug the other monitor in where that one is to see if that makes any difference. Your video card may have come loose inside the computer and that can cause that too. If the other monitior shows signs of the same issue, unplug everything and put the desktop on a table, get a screwdriver and a flashlight, undo the lid , there should be an access cover or maybe the whole cover has to come off, study where the monitor plugs in, but on the inside, its a medium size circuit board, and theres a phillips head screw holding it to the frame,see if thats loose, look closely to where the video card is plugged into the big circuit board and see if its loose, gently push it back into its slot, tighten that phillips screw
hopefully that helps

Samsung Monitor Syncmaster 913V Montior Screen shows patches of screen on desktop and playing videos

Sounds like your LCD panel has gone bad.

If the unit is under warranty, take it to a Samsung repair shop. If it is not under warranty, go buy a new one. LCD panels are usually more expensive then buying a whole new monitor.

Irritating display

This is a sure sign in CRT screens that it is on it's last hours of life. I saw this in one of my customer's screens and I told him it was probably dying, it died the next day. You could try opening the menu and hitting degausse or whatever it's called. That helps sometimes, but if this is doing this repeatedly, it means your screen is dying.
