Question about Samsung SyncMaster 793MB 17" CRT Monitor

Open Question

Brown lines My monitor suffers from intermitant brown lines creeping from the right to the left some times obscuring the whole screen. My research says this is common across many of the SyncMasters the 793's inparticular. I have not found step by step instructions on how to fix it myself. Temporary solutions range from slaping the thing to turning the brightness  up to max.

    I experienced these very same problems with my 793 monitor which is around 3 years old. The brown lines usually disappear after 3-4 minutes but can and do reappear just about any time. I've noticed nothing in particular that causes this to happen. Only waiting it out seems to be the solution.

    I have the same creeping brown lines sometimes disapears even for some day but again appears and sometimes it spreads for the whole screen
    i have this problem for about 3 years

    I have this same problem. I keep a rubber mallet next to it. I got tired of hitting it with my hand, now I just tap it on either upper corner. A friend thought I was going to kill it. One day I will too. I had it apart and reseated all the wire/cable connections this curried it for maybe 6 months. Good luck. Hank

Screen is fading left to right. text starts black and turns to brown


Might be that your monitor is starting to go bad. Try another known good working monitor on the computer. If it works properly then you know its a problem with your original monitor. If the 2nd monitor doesn't work properly then its a problem with your video card.

If your original monitor is the culprit then it could be bad caps on the main board but regardless you could possibly take it back to Best Buy and get it replaced since it should at least still be under the manufacturers warranty.

Brown horizontal lines sporadically appearing on monitor


I had the same problem. I fixed it completely today. The horizontal lines disappeared. IT IS DEFINETLY THE DEVICE DRIVER. I confirmed my monitor model tyope (dell M783s) and downloaded the specific driver for this monitor.

I had to do these exact steps or did not work.
1) with the problem screen, disabled the display adapter under the Hardware/Device Manager settings.
2) Restart the PC
3) Boot will come up with brown lines still but the screen will low resolution of 600x800.
4) Then I installed the correct device display monitor driver onto the pc. ( you may need to scan for new hardware, then choose the directory with the new hard drive.)

If you need step by step... just reply back.

Not a whole I can do to help. What I can do is refer you to go get a Chilton, or Haynes manual thac voers your Plymouth Voyager. They have schematics with wire colors labeled.You will have a good shot at figuring out which wire is which.

What is brown out


Brown-out .... What is it? Brown-out is a condition of lower than normal power line voltage being supplied by your local utility or generating equipment. This condition may be short term (minutes to hours) or long term (1/2 day or more). A power line voltage reduction of 8 - 12% is usually considered a Brown-out.
What causes Brown-outs? Electric utilities (your local, lovable Power Company) may occassionally reduce line voltage to Brown-out levels in an effort to adequately manage power generation and distribution during periods of heavy usage. Very hot days, when most air conditioning and refrigeration equipment would be operating almost continuously, is an example of such a situation.
Even without utility intervention, extreme overloads caused by most air conditioning and refrigeration equipment operation could tax the electrical distribution system to the point where a permanent brown-out state could exist over much of the power company distribution network.
Locations at ends of long electric distribution lines may experience chronic Brown-out conditions due to line loss. Intermittent heavy loads on this trunk circuit may cause the Brown-out effect to fluctuate with the load.
Installations using ship-board or temporary power sources are especially prone to operation in a Brown-out mode. Usually of limited capacity, it is quite easy to overload the power source, giving rise to permanent Brown-out. (Permanent Black-out, if users are not careful).
What are some common effects of Brown-outs? Brown-outs are the mother of all sorts of Bad Stuff.
Power supplies in some electronic equipment may fall out of regulation. Errors, due to erratic power supply performance, may creep into computer operations.Other electronic equipment may function poorly - or not function at all.
Marginally performing devices (electronic or electric) will probably cease operation entirely.
Motors will overheat. Some motor types will slow down.
Electrical interference will greatly increase. Increased interference may affect computer and communication operations.
Off-line UPS units (the vast majority of lower cost units) continuously cycle between power line and internal battery operation. UPS batteries (generally sized to provide only 5 - 10 minutes back-up) will soon be discharged, unable to generate additional Back Up power. You are out of business. If system has not been shut-down, the entire system (UPS & computer) may snap back to life when power rises slightly, only to again shut down when the power line voltage falls back into the Brown-out zone. Such "ON-OFF" operational cycling is unhealthy for UPS, batteries and connected electronics. For Brown-out correction see our Voltage Regulator Page.
Spikes generated by electrical machinery also greatly increase. Air conditioners, refrigerators and other motorized devices generate local spikes. Industrial machinery (often miles away) create additional spikes which may find their way unto the electrical distribution system, and into your sensitive, valuable equipment.
