Monitor Malfunction
you are a retired electronics service engineer and it has you beat --time to junk it as it must not be repairable
I have SVA VR 15A Flat Panel LCD Monitor . but
The power supply has a bad capacitor. It's 4700uf at 16v, electrolytic. You'll notice it from the slight bulge in the top that may be very apparent or barely visible. Replace it with a LOW ESR cap of at least the same voltage rating as the original if not greater. Simply de-solder the old one from the psu board using a soldering iron and some
solder wick, insert the new capacitor, polarity correct, and you should be fine.
The capacitor will cost about $2.00 not including shipping.
Here's a link to Mouser. Don't buy this capacitor until you've verified the value and voltage from the one on your monitor power supply. It's alright to use a slightly higher (up to 10%) value of capacitor and the voltage doesn't really matter as long as you're over the rated voltage of the unit you're removing.
Don't do this if you have no experience, the voltages are high enough to hurt you and you may regret it. This monitor is worth less than the cost to repair it but if you're set on it fine.
Conectng securety camera to sva monitors
It depends if the camera has composite video output or is an i.p. camera. Most likely it's composite video output in which case you'll need to
purchase a scaler like this one. If the camera is an i.p. camera then you simply use a computer attached to the same router or subnet and open a browser window and navigate to the same i.p. address as the camera, you may need to know password and username to log into stream.
How do I fix the color?
No! the problem is in the LCD panel display, behind the LCD is a large circuit board that process video, colour, brightness, and balance, if that goes wrong it throws the colour content off, replacing monitor best option. But first it would be a good idea to sub the video cable from the monitor to the computer to cover everything and hook a spare monitor to the computer to rule out the video graphics card.
VR-15R monitor in sleep mode
Most likely your issue is a bad video card or a bad vga cable. Try swapping video cards and see if this doesn't solve the problem. You could also use a vga signal generator, available for pretty cheap, to inject a signal into the monitor to determine if the problem is indeed your source rather than your monitor. If the monitor is the problem, you can try troubleshooting the various components on the circuit board with a huntron tracker while the unit is powered down. But then, I digress, as this is quickly becoming a solution beyond my ability to explain to you the inner workings of such things as a pn junction or the phase lag of a capacitor or the ringing of an inductor. Sorry, might be best for you to simply buy a new monitor. Ones like these cost, what - oh, look! FRee on craigslist.

You could also use better descriptive words and sentences to help me - help you. I have no idea what you're asking. Sorry.
Sva monitor model 2400w-bd.
Your monitor is suffering an overheat condition due to the switcher internally working too hard and overheating, shutting down the switching supply. Replace the electrolytic caps on the board with new low esr ones and you should see this problem go away.
SVA 24" the monitor
This is a problem on the power supply board...probably the inverter has a issue ..To give you a clue ..it has a bridge board that transforms the ac current into dc ..and if a condenser or something is failing ..the current it receives it is not accurate anymore..and it gives it this chaotic behavior..
My advice ..is to change the power supply ..cause this may be something you can do by yourself ...If you want just to fix the issue ..it may cost you more to pay a repairman ..
http://www.sva-usa.com/partsandservices.htmlif you want a second opinion ..or the parts ..this is the link to order for them ...(you may find the parts on other sites too ...)
I have a flat screen
This means your video card is set to a frequency that is too high for the monitor to match. Lower the switching speed via the properties window on the computer. Try 800x600 @ 60hz for starters. You can reboot into safe mode by pressing and holding F8 as you reboot. This will allow you to boot in a low resolution mode which should allow you access to these settings.
My SVA Monitor just started
Unfortunately this isn't a solution but a request for one, as my monitor does the same thing. D: Anyone?

SVA VR-17s, I inadvertantly reversed
It difficult to say what thing or things got damaged when they are reversed biased. If you are lucky it could just be a fuse, otherwise there could be a lot of components that could be damaged by the reversal. Only way to know the extend of the damage is to pop open the case and look inside. I would check if it has a fuse first and the condition of it and look for any obvious parts that were blown up. Unless you know how to troubleshoot electronics, it not worth the trouble to try to see if you can fix it considering how affordable LCD monitors have gotten.
