Check all connections (power and data cords on both ends). Otherwise, these don't last forever and may be near the end of it's useful life.

It will be more likely to have power supply problem, open it up and look for bad caps with bulging tops first and report back what you see so we can guide you further, see failed SAMSUNG monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

- You can test the monitor by using another CPU, if still the same then the problem is monitor, but if it's working well then the problem is your CPU, to make it sure then you can try another monitor on your CPU. - check if the hardware connection is well attach, you can pull & re- plug the hardware just to make sure. - the monitor is need a DVI connection (white or gray) to run properly, if you use AGP connection ( blue ) on your VGA card that might the problem, so you can also try upgrade your VGA card. - other ways is to install the latest driver for your VGA card.

The menu popping up sounds like faulty switches, easily fixed. That may also be the cause of the switching off as well, or it could be a symptom of bad capacitors also easily fixed. So I've posted my solutions for both here.


Switch solution

--------------------


You have 2-3 options.

1. If it's under warranty then send it back to be fixed, although you'll probably have to pay for it to be sent back etc. But anything else will void the warranty.

2. Pay a tv repairman or similar to fix it for you.

3. You could remove/replace it yourself if you're handy with electronics, or know someone who is. The part itself is called a tactile switch and should cost around £1 if you live in the UK. Make sure you get the correct one as they come in different heights and orientations.

Should look something like this:

Tools
-------
1. Soldering iron - 40w+
2. Solder - not acid core
3. Phillips and flathead screwdrivers

Instructions
--------------
1. Unplug monitor and open case, you may need to carefully lever the case off with the flathead screwdriver.

2. Find the little board with the buttons on, and identify the faulty button(s). This is done through watching what is happening with the menu or a trial and error process.

3. Very carefully heat up the contacts on one side with the soldering iron, you'll probably have to do the two contacts at the same time, and rock the switch the other way, then do the other side, keep doing this until the switch comes out.

4. Either test without switch first or just replace with new switch. Make sure it's securely seated, correctly, and soldered in. Make sure the solder is neat, tidy and doesn't contact anything else.

5. Replace casing and test. If it doesn't work then you'll have been a bit messy with the solder, tidy it up and try it again.



Bad Caps solution

------------------------


p { margin-bottom: 0.21cm; }a:link { }

1. If it's under warranty then you could send it back to be fixed, problem is they will likely use the same rubbish brand of capacitors again, but anything else will void the warranty.

2. Pay a tv repairman or similar to fix it for you. They may still use substandard capacitors, so specify what brand you want them to use, this will probably mean waiting longer and possibly paying a little more. This way you know the job should be done right.

3. You could replace them yourself if you're comfortable with a soldering iron, or know someone who is. The capacitors themselves are quite cheap and easy to replace.



Go for the best ones you can get for the job and try to buy from reputable companies, the links below will help you chose but you can't go wrong with Rubycons. Every capacitor manufacturer has several ranges, each having different properties which make some more suitable than others




Always match the values on the original capacitors. You can actually use slightly different values for the capacitance and voltage (uf and v) but never use ones below what the originals are rated at.



The links below will explain this further.



They should look something like this:
drunknmonkey_4.jpg
As you should be able to see, the one on the left is bulging. The blue stripe with the arrow tells you that the lead on that side is the negative, the positive lead should also be longer than the negative one(only on a new cap, old ones will have been trimmed).

Tools needed
-----------------
1. Soldering iron. - preferably with a stand with a sponge in.
2. Solder - there's different types so make sure it's suitable for electronics
3. Phillips screwdriver
4. Flat head screwdriver
5. Wirecutters
6. De-soldering wick, or pump. - definitely recommended but not really essential.


If you haven't already got the tools then it's a good investment, as bad caps cause a lot of faults in all kinds of electronics.


Instructions
--------------
1. Unplug monitor and open case.

2. Identify power board, it should have a lot of electrolytic caps on there and obviously should be connected to where the power lead is attached.

3. Identify the bad caps, they should be bulging and/or leaking, although not always. Note down the three values for each cap (eg 220uf, 16v, 105c) and their approximate dimensions, and get new ones, preferably Rubicon or Panasonic, the link below will help you chose some good ones. If in doubt you could remove them and take them to the shop, but you'll have to remember where each one goes and which way round it was (take pics).

4. Very carefully heat up the contact on one side with the soldering iron, and rock the cap the other way, then do the other side, keep doing this until the cap comes out, if you have a de-soldering wick/pump use it to remove the solder and it should just pop out easily.

4. Replace with new cap, making sure that you observe the polarity and make sure it's securely seated and soldered in. Make sure the solder is neat, tidy and doesn't contact anything else. If there's any solder left in the holes then you'll have to heat it up or remove it before you can get the new cap's leads through. Once done properly trim the leads off so they won't cause any problems.

5. Replace casing and test. If it doesn't work then you'll have been a bit messy with the solder, tidy it up and try it again.

You have failing LCD panel, see example here: http://s807.photobucket.com/albums/yy352/budm/LCD%20panel/

It will get worst with more lines, you can try reseating the ribbon cable on the T-CON board to see if it helps.

I would take it back right away, when electronics break down in lees than 6 months it is not a good sign. Get the replacement or have it fixed under warranty.
