KS Vertical Lines in all inputs.The intensity of the vertical lines changes with the RGB signals and very prominent on white video signal as shown below:. Since the vertical lines are not in the static location and always changing with the video display so, it is unlikely the LCD panel is at fault.

The possible cause could be the main board, T-con board or both. I performed a grey scale test with the same procedure as in my earlier article on gamma distortion. There is no gamma distortion or noise on the grey scale but RGB vertical lines are being superimposed on it see photo 1. The intensity of the vertical lines changes with the contrast level as well. I suspected the gamma IC is faulty although it displayed no gamma distortion. After changing the this IC there is a remarkable improvement on the video quality except for some fine vertical lines still visible only at high contrast level.

As I have suspected earlier the main board is also contributing to the problem. Changing the main board will be ideal but may not be worthwhile as the main board is not cheap.

TV Has Different Color Vertical Lines On Screen – How To Fix?

Well done with nice photos and explanation. Sometimes we must make compromise between price and repair results. This was worth the repair I think. My best regards. Humphrey Kimathi. Excellent work SK Wong, A satisfied customer will always come back and refer others too, Again thanks for keeping the repair cost low in order not to burn a hole in his pocket. Regards Humphrey - Kenya. Hi SK So maybe the iMAC LCD panel includes the electronics and replacing the panel coincidentally replaces the defective chip.

QFP-packaged ICs are indeed horrible. Especially when they are that small. I have watched a video by Shop Jimmy lately on Youtube. This guy knows how to do it. I think the key is to use just the right amount of solder paste for the bottom pad so that the chip does not float too high on top of the molten solder. It should just sit tight enough to let the contacts take on solder via the ironwhich is applied with a lot of flux gel.
