When ever i turn on my monitor, it shows vertical colored lines of green blue, yellow, pink, and red lines all over the screen, i tried checking the connections, i turned it off and on several times, even if it is not connected in the cpu, the colored lines still appear. what should i do? please help. :-s

Hi, This sounds like a color driver problem with the RED. I will assume that the blue is good since yellow will only be present if the green and blue are both ok. Below is a copy of my response to a similar post at http://www.fixya.com/support/t181021-zenith_a25a11d_no_red_color "...If you are comfortable working with a soldering iron, a continuity (VOM) multi tester and a fair knowledge of electronic components, then perhaps you can repair the missing color red. You have to open the unit, expose the small printed circuit board that is attached to the small end of the picture tube. There will be many components present but you will need to focus yourself on three (3) transistors that are bigger than the others sometimes with an aluminum heatsink. It is also possible that instead of 3 transistors you will have one power IC. In any case these control and provide the drive for the 3 colors of your picture tube: red, green and blue. One of them is either dead or suffers from cold solder to any or all of its pins/legs. You have to visually inspect the solder joints of these big transistors/IC and determine if any is dull in color, loose of simply not connected. You may even try the shotgun approach and solder each of the pins/terminals/legs just as long as you don't cross solder creating a short between pins/legs. If this works, you're set, if not: You have to check with the use of the VOM and determine which of the 3 transistor is defective. If you are familiar checking continuity of base to collector to emitter and reverse, again you're set, if not perhaps you check all three and compare which have the same reading from the same position and which is different. Pls keep in mind the transistors have forward and reverse bias readings. If able to determine defective component, desolder, replace and solder. If it were an IC, replace the entire pack. If the above would make you uncomfortable, pls ask for the services of a qualified TV repair man and explain your problem..." Hope this give too an idea. Good luck and pls post again how things are or if you need further information. Kind regards.

Hi Detrix, Check with www.lcdrepair.net if you want a repair. Something is wrong with your LCD controller and or GUI interface circuit or the circuit supplying power to it. If your technically endowed, you may want to open the monitor case and clean the dust and lint from around the circuits using a Small paint brush to sweep away any built up dust. These circuits take the Signal from the computer and controls the 2.5 million pixels on the LCD screen. Dsut can cause major problems with handling all that data. Give it a shot, what do you have to loose, its not dangerous if the monitor is unplugged.

Your panels are dying.
Well more to the point the driver tabs that run the panel are dying and are not going to be cheap to repair for either case.
For the stand alone LCD, it is cheaper to get another one.
For the laptop, find a laptop on Ebay or similar with a dead motherboard and swap out the screens, also gives you spare parts for the laptop. If you goto a repair shop and get a screen it will cost you as much as a new laptop.

It's because I accidentally plug the cable to the built-in graphics card port. Now I connected it to the right one and my monitor is working great!
