Green flickering pixels.

[Robert_H]

Hey.

I got a broken LG Widescreen LCD Monitor W2453SQ from a friend, and I decided to try and fix it.

I opened it and saw that 4 capacitors had popped, so I bought new ones online and changed them.

Now when I tried to plug the screen in I get green pixels all over the screen.
I´ve tried plugging the screen into 2 different PC´s and I get the same problem.
I dont get the pixels on any other screen I´ll plug in. (I´ve tested with 3 other screens)

I didn´t manage to take a good picture that shows the prblem, but I found a good image online with a similar issue.

Does anyone know what the problem can be?

Possibilities:

A) Wrong replacement capacitors.
B) Whatever blew the caps also damaged other components.

The capacitors are the correct type. I checked very carefully before I ordered them. I can´t see any burnmarks or something obvious damage on the card. Is there any way to see if some other component is damaged?

Does the monitor only have one input? If yes check the connector itself. If it has more than one, test it with the other inputs.
