My samsung TL220 i dropped it won't power on or anything


Things to check first for a camera that won't turn on (no power, no lights, no noise, nothing) are battery contact points, and micro switches that are located on the battery and memory card doors. Troubleshooting tips on other things that need to be checked may be seen here. These tips won't work for every case, but they're worth a try.

But if there is some electrical activity, then you're more likely experiencing a lens error. In that case, see this article.

I turn on my samsung syncmaster710 and it just has a black screen, with a faint (very faint box floating around it. is this a fualty backlight?


The backlight invertor seems to be defective.
Check the main power supply board for bad capacitors (visible damage ) and make sure that the invertor tubes do not light up for a moment when you power up the monitor ( in that case their probably is one or more light tube defective (burnt)) --

Monitor comes on then after 2 seconds screen goes black then if i turn it off again then repeat the process does the same thing


hi,

the power supply of the light tubes is not working well
you need to replace the capacitors of the power suply
the value of the capacitors are bethween 220/40V 470/40V normal theire are 2 pieces.
you will find this in the bak of your screen after removing the cover, its near the tube connectors located.

Lcd screen shuts down


the powersupply for the tubes is defect.
you have to replace some electrical condensators
( elco) I think betwheen 100/40V and 470uF/25V
you will find different piece's inside
look near the transformers on the bcp where the wire for the tubes is connected. just replace them and it will work

Static noise on all radios in house including transistor unit. Turn off monitor static goes.


you have a problem with the power supply. this model has ex external switching power supply like on some laptop. 12V 3.5Amp positive tip output. To test this you would have to plug the Power supply unit and put a load on it other than the monitor. Not easy to do if you know noting about electronics.
You can get some made for laptops and other things like external hard disk.
There is also the inverter inside the monitor that drives the small fluorescent tubes . this could also create the noise. One way or an other you will have to replace the part.

My Dell monitor gives sharp noise when started without connecting to the CPU.When system has started it works fine.Can I know how to solve it please ?


Hi!
I used to have a monitor similar to yours, from the noise you are describing is it like a crack? or an high voltage electrical spark/arc? (Mini lightening flash sound).
The Monitor I had De-gaussed each time it was switched on this is a weird thing that lines up the colour guns. If done whilst in use it gives the brief appearance of a shimmy/shake to the screen.
Have you a menu bar on or near the power on/ off switch? if you do try looking for De-gausse it may inadvertently become switched on to auto. You can De-gausse manually.
I do hope this helps.

The monitor brings a 10cm thick line after powering on


this type of problem is may be due to the magnetic appliances near by ur monitor such as speakers etc... try keeping the speakers away for some distance and then in the monitor there will be one menu just press that and then go to degauss and give degauss... your problem will be solved...

if problem persists then may be the tube is gone just visit the technician ... he may tell u that he must recharge the tube....
