Question about Samsung SyncMaster 245BW Monitor

1 Answer

245BW Snap/Crack sound and then does not work

The subject says it all... I was filing some papers - nothing unusual going on - heard a very sharp snap or crack sound and the monitor was no longer working. The power button was still working and getting electricity, but a dead screen. Any ideas what this could be? I'm pretty handy with repairing PCs and I was able to get the back cover off with no problems, but couldn't see anything obvious.

Thanks for any help.

    I have just experienced a very similar problem. Suddenly this morning my 245B just woulnd't show anything.. the screen is completely black, but not an illuminated black, black as if it were just turned off constantly. The only difference between its current state and it being turned off is that the power button seems to work as normal so I assume it's not a power source problem.


    I also have heard it 'crack' various times throughout the last few weeks(?) after approx. 45 minutes of usage when first turned on, and sometimes after it is turned off, but this didn't seem to have any effect, so I ignored it.


    Jmassengill, have you managed to fix your problem?


    Thanks

Be very careful! Some monitors/TV's have 30,000+ volts DC in them even when not plugged into AC house current. The crack/snap sound was most likely an electrical component breaking down and shorting against the metal of the case of the monitor. I would take the monitor to an authorized repair center because the danger of getting shocked/killed is very possible while working on this type of problem at home.

Hp va19b. How do I open the case? If I put a screwdriver through the hole in the back, nothing seems to happen.


The hole is for anti-theft security attachment. You will need thin flat blade screw driver to crack open the case, start at the bottom edge first and then work your way around, the bad part is that there is no slot to show you where the snap-in tabs are located.

Monitor will not display in native resolution.


sounds to me like they replaced your vga board with another compatible one but not the same exact one I would call the repair facility that did the work and ask questions about how they repaired the monitor like if they used another vga board etc. hope this helps

Open the LCD cover


I had the same problem and it was quite difficult to open the case. So now I want to share my experience on how to open it and also publish some helpfull pictures (of course these also works for the 2007 screen):

1. I made a tool from the top of a aluminium can. It's quite thin and bendable but still strong enough (make sure there are no sharp edges).

2. You have to understand how the parts of case are joined together and hold by snaps. Here a piture of a snap. The front frame has bails(?) hitching on the snaps (see picture 3).

Move the tool between the bails and the snaps so they will let go. The first snap is always difficult. Start at the top or bottom, because the sides have a "double" wall (see picture 1 black and grey) and it is difficult to find the right way.

There are five snaps on each side. Always one in the middle, one on each corner and one between. Start with the middle one. Use a screwdriver to get a little gap between the two parts of the case. Push the tool inside til the snap will let go and the case opens a little. Continue with the next snap.

When the case is open be carefull there are same cables soldered to the front part.

If you have a problem with the power button. Usually there is a thin bolt missing like the other buttons have. I glued a very small screw into the button. One like used to fix the small circuit board. Make sure the length is appropriate.

Broken Monitor


Hi Roeder, I have never heard of an LCD screen cracking from anything other than physical force, this is a first for me. It is possible since there is high voltage power in there for the backlight. In light of the sound I suspect a component failed, generated lots of heat real quick and caused the crack/failure. This is really unusual and you might try calling Gateway to see if they will replace it, especially if it is one year or less old. I would resist all temptation to open the LCD till you call Gateway. If they will replace it they won?t be happy to find you opened the case. Let us know how it works out and please don?t forget to rate this post.
