Samsung Syncmaster 173V Wave like pattern on 2 monitors

I have 2 Samsung Syncmaster 173V monitors and they are displaying a mutlicoloured wave like pattern with or without VGA input. Backlight is fine and power rails appear to be good on both monitors. I have tried replacing electrolytic capacitors on the power supply board and the processor board but this does not fix the problem. As it is happening on both monitors I suspect it is a common fault

    Thanks, firstly I dont have a schematic



    I think the components you are reffering to are for a CRT monitor. This is a 17" LCD

My syncmaster 173 turns on for few seconds and than turns off


Its a fairly common problem on LCD monitors. One of the capacitors on the circuit board inside has probably failed. Its a case of replacing the capacitor, circuit board or the monitor.

The monitor turn on and inmediately turn off


This would be due to a bad power supply board inside, replacing this will put you back into biz again around $50 for the part @ samsung.

Thanks

The menu constantly pops-up on my Samsung 17 inch LDC monitor


what does the pop up menu say? I'm guessing it says something like "Optimal settings are 1280x1024, Press 1 to confirm, press 2 to disable". If the message is anything like this, your monitor is trying to tell you that your display settings are less than optimal. You can either disable the message by "pressing 2" or changing your display settings to the recommended resolution. If the menu you're getting is just the control panel and there's no actual message, leave your computer on, reach around the back and disconnect the power cable from the monitor, wait 5 seconds and plug it back in. Samsung monitors sometimes have a glitch and need to be reset.

173v flat lcd black screen


I've had a similar problem with my 173v monitor since I bought it a few years ago. When I start my computer, Mac or PC (I've connected it to both), the screen remains black and the green power light flickers once a second, almost like it's twitching - it's different from the blink it makes when the computer isn't turned on but the monitor is. Like kronem, I have to unplug the line from the monitor to the computer, wait for the monitor to register no input, and then plug the monitor in again before it displays anything. I've never figured out a way around the problem - I hate it!

Cannot find VESA holes...Samsung Syncmaster 970p


I have looked at the specification for this, and although it does show as being VESA compatible (This is a display standard) There is no mention of any "wall mounting" capabilities at all, which would lead me to believe that this is not designed to be put on a mount. also the "Magic Rotation" Technology which is part of this device may rely on it using the proprietory stand, it may well be possible to remove the stand however, but it would require some significant dissasembly as the power connector is on the signal box, and this would need to be seperated from the stand itself. The mounting bolts look to be hidden behind the round pivot cover on the back, and it may be possible to see if mounting is possible simply by removing this, however I would seek information from the manufacturer about this as removing any of the covers would most likely invalidate your warranty, it is possible that this was missold to you and you should be able to take it back as not being fit for purpose.
