Hello! I've got a problem with my Samsung


You may still have the problem with the 5vdc filter caps problem, bad cap can look normal but can have high ESR. I always repalce them in a set not just the bulging one. The 820/25vdc caps are more likely to be for the 18vdc inverter backlights circuits. Inspect the caps on the logic board also.

Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

Dear sir i ve lg 795 monitor which is now creating a problem whenever i switch it on, it sound like a spark beep same time the picture size goes larger and then with the time goes smaler(like zoom out)...


The Line-Out-Transformer is weak and the relay (spark beep) needs to be replaced. It is best advised to get in touch with a monitor technician who can replace the LOT and relay. If not, trade this monitor for a new LCD monitor.

In some cases, such problem could arise if the picture tube's electron gun circuits have become weak!

My monitor worked great for the period of 5 years or so...then one day it doesn't want to come on, the power light would flicker...anyway I removed the panel and looked for popped capacitors and I can't...


Bad caps can look normal but it they can have high ESR, but you should take some voltage readings first, it should have 5vdc and 12~16vdc when the monitor is plugged in but not turn on.
Post pictures of the caps also, many people told me the caps look OK until I see the pictures and they turn out to be bad. You need cap meter taht can read capacitance and ESR.

Screen goes black and then comes back on. It makes a double beep sometimes when this happens.


sounds like a loose cable or improperly seated. power or signal cable. Unplug all ends, and replug with snug fit. Most monitors dont beep. are you sure this not the computer restarting. I have also seen loose graphics cards sometimes do this. inspect where the card seats into the graphics card slot. see pic. (the grapics card is red in this picture.84a853e.jpg

VA1703wb... Monitor beeps when I turn on the pc then goes black


Please read below and look at the pictures of failed VIEWSONIC nd othe monitor before try to DIY repair.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

My screen does not come on when computer is turned on.I have a samsung syncmaster 2253lw as my main screen and have had both operating in the past at the same time.


Please check your plug if it is plug in properly or firmly. Locate the switch and turn it on again. If stil persist, try to inspect whether cpu is beeping while turning on. If its beeping something is wrong in your cpu or monitor depending upon the beeps.

My Samsung Syncmaster 240T stopped working today. I tried turning it on, and it starter emitting a constant short beep once every 2 seconds or so, along with the green Video light blinking every time it...


Hello,

Your Back light inverter power board has died. The beeping and blinking are caused by the power board repeatedly trying to start up and failing. This is a common failure point of LCD monitors2.gif after a few years of use. The heat build up in the monitor case causes parts called capacitors to blow leading to the power supply short. If you can solder you should be able to do the repair. Go to our web site at:
www.ccl-la.com/badcaps.htm We have pictures of what to look for. Now take the back off of your monitor and replace all of the caps that look like the pictures and you should be back going again. Be sure to use high temp parts, they will be marked 105c. The values you will need to get will be marked on the sides of the bad ones such as 220uf, 470uf or 1000uf. When you insert the new ones be sure to put the polarity stripe going the same direction as the old one comes out. If you have any questions just let me know. If you don't want to do the repair yourself we do offer a repair service for $30 + return shipping2.gif.

I hope this helps, if so please rate our solution.
