Re: Noise-like problems on Samsung T220HD



The first thing I've done before dissasembling for the first time the monitor T220HD was to switch my GPU (ati 5770 to a nVidia 8400GS) and the monitor presented the same problem. Then, I've disconnected all the inputs to the monitor, having only the DVI input from the Pc and the AC power cord to turn the monitor on (with just this power cord plugged to the wall). Same problem. Then I had tried disconnecting all except the power cord (obviously) to watch only TV: same problem (although on TV was lesser noticeable as on TV they...

Re: Noise-like problems on Samsung T220HD

The position is random as it is showed on the photos with the different standard colours that power point may offer (at that time, I wasn't eager to make a vector o colours, just test why there were noise on very bright colours and white ones), no stuck pixels. As I've said on my first post, the first time these 'noise lines' appeared were for a short time and vanished. The next times appeared for a little bit more time (turning on/off the monitor did not fix the problem) and finnally, the lines appeared always on the monitor (with more...

Re: Noise-like problems on Samsung T220HD

Thanks for your input selldoor!

About the photos, sorry and 'll try to do that. I've just linked an external link in order you can see them at full resolution.

About the connector, yes, I've done that and the problem still remains (which is what I was referring to on my second post at this thread. Sorry if I wasn't clear). Also, I've done that with the other connectors of the main board and the power supply with the same problem (still the same).

So, do you have any other ideas? Maybe is the chocke...

Re: Noise-like problems on Samsung T220HD

Hello and thanks for your response,

With the malfunctioning mainboard, I've tried to reseat the cables 1st (plug & unplug). Then after the history of the previous post, I've done the same thing. How am I sure that I am connecting the cables correctly? Well, the main board has a connector like [URL="http://pc-level.com/wp-content/uploads/2012/02/msi-wind-u135-touchpad-cable.jpg"]this one[/URL] (I can tell you the name in Spanish but not in English), so believe me is just imposible to go wrong putting it out and...

Hello to all the community,

My name is Javier and I am from Madrid (Spain), so English is my second language, then I would like to apologize in advance for any grammatical or mispelled words. Also I am at my least year of telecommunications degree specialized at electronics that maybe on Europe and USA is the same as electronic's engineer, so I think I have the background, knowledge and skills needed to try to fix the problem of this monitor (also I've done some maintenance like ~4 years ago on another electronics devices for a company).

Like a year ago my T220HD...
