Migrating Pixels means, you have intermittent bright spots on the screen? If yes I am afraid it is an issue with the display panel. However lets confirm before we come to a conclusion. Did you check the Y-Sus and Z-sus board for any apparent damages?

Screen does not lighy


If you look very closely, is there an extremely dark picture, or a solid black screen? If it's an extremely dark picture, you just need a new backlight. If it's a black screen, you either have a bad connection (broken, shorted or unplugged cable), or need a new LCD. Let me know, and we'll go from there.

I have an LG Flat Panel 37LG 50-UG.ACCOLJM. The picture has many vertical lines less than a CM apart and the colour is wrong and looks negative (light is dark and dark is light)


Hi,
All Plasma and LCD TV have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times reseating the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken if you decide to tinker with em, the usually have lift locks that release them,. Good luck in solving the problem and do take care because it contains high voltages.

My hp C7180 all in one printer told me I needed to replace an ink cartridge as it would not print in color. I replace the one it said, still did not work, I have replaced all the cartidges and it is still...


First perform an observation of the printers compartibilty to color printing. For example, the printer ought to have been manufactured to capture color pixles to provide resource request in multimedia. usually is possible to have one printer that has several ink location areas to either install color media or dark ink media. In situations where a printer was designed to be black and white ink document compartible would least produce results on color when ink was interchaged. Ascertain that the printer is compartible with multimedia pixel printing proir to acquirng depeltable resources from retail.
