Sony 910 baby monitor makes loud beeping when turned on


The picture you posted looks like it has the channel setting option. Notice at the bottom there are three little holes that are (as I recall) either red, yellow or green. You have to set the channel on both the transmitter in the baby's room, and in the receiver you keep with you, so that they have the same pattern of colored dots in those holes. When they have the same pattern, they're on the same radio channel. If you can hear a neighbor's monitor, pick a different color pattern to change channels. As long as both units have the same pattern, you should hear the baby, not the beeping.

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.

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 hp computer wont display picture and makes a beep noise when i turn it on


It should make one beep. That means it passed the self-test.
If there is nothing on the monitor (is the monitor light green or yellow?)
then the monitor is bad.
I suggest you try another monitor to be sure. Borrow one from a friend.

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.

No picture and desktop makes beeping sound


Base on the post codes this continuous beeping indicates a power problem. Atypically this is a power supply problem and it will need to be replaced.

Lcd monitor won't turn on


Hi,

the fact that there is no picture it doesn't mean that the lcd monitor wouldn't turn on or would be faulty.

It means that the monitor is not getting picture from the computer, the cord could be loose or the computer has a problem and its unable to start up or send signal.

you can try the monitor on another computer that works, to find out if the display works fine.

if the display works fine then the problem is the computer not turning on or starting up, if there is a fault or error you should hear beeps, the lack of beeps may also be a sign of a fault or a error.

What you can do is, unplug the computer for 10 minutes and try turning it on again, reconnect the display cable and try again.

Do you have a screwdriver and is the computer covered with warranty or not? if the computer is on warranty better not to get inside, just contact your dealer and get it serviced.
