Hi. I am using a Amoi LCD TV LC20D5S. When I turned on the television, the screen shows Amoi with a background blue screen. Next, the screen shows wavy colourful lines. The coloured screen just remains that way. I tried re-plugging the wires but the problem still persist. May anyone please help my ASAP? Is my TV spoiled or is there a way to fix it. Thank you.

SOURCE: Tv showing blue screen with flyback lines sound ok

Flyback lines? Is the picture all white with no brightness control with faint horizontal faint lines? If this is what you are saying, the screen voltage could be bad, and if thats the case, the picture tube or the flyback itself could be bad. You could also have a bad connection on the crt socket

SOURCE: no colour on television

Hi, It is possible that the reason for the black & white as well as lines across the screen is weak, defective or wrong oriented antenna. If you are hooked up to cable, then it should not be a problem as you can call for service; if on the other hand you are using aerial antenna, you can try to: reorient or adjust the direction to where the antenna is pointed until the reception improves, check the lead in wire (cable or flat) for any breaks or shorts or loose connection, check/clean the connection of the antenna elements to the cable/flat wire, replace your aerial/cable as may be deemed fit and needed. A couple of questions pls if the above does not solve your problem: when receiving from aerial, is the picture full vertically? are you also having problem with sound? If yes, where was the TV bought and where is it being used now? If no, is the image snowy and some channels/stations are better than the others? Good luck and pls post back how things turn up or further information. kind regards.

SOURCE: LG PLASMA TV WITH COLOURED LINES OVER SCREEN

If the Video (Picture/Pix) is gone but you can hear the Audio (sound), then it could mean the YSUS PCB Assembly is gone/kaput/finish. Can replace the PCB, not repair the PCB due to timing circuitry involve. Cost maybe roughly $500 depending where you located. The PCB is located on the left hand side of your TV when you are facing the back (Back open). Might find 3-4 brown flex membrane connecting to the plasma panel. The PCB has a silver or black aluminum heatsink (big) on it.
Good Luck.

SOURCE: westinghouse LCD TV - broad vertical green and blue lines

try to go to the factory reset and see if that helps. If not, you can then check your connection. if you use component (red, green and blue for video and red and white for audio), make sure all the color matches when you plug it in. if everything have been checked then you need to replace the main board and it should correct the problem.

SOURCE: although tv is showing picture the colours only

Hello
Your TVs red colour output section has the trouble. There is no red output at the red cathode of the picture tube. The red, green, and blue output sections are on the picture tube base board. In some Philips model, these will be consists of transistors, and some has an IC or Tree ICs for three colour output used. You just open your TV, measure the voltages at these three cahodes. There will be markings on the printed circuit board for these cathodes marked as [Rk,Bk and Gk].
In your TVs case the voltage at the Rk marked pin will be higher that the other two cathodes. This can be caused by an open drive transistor or an Ic whichever may ysed there. If it is transistor, just replace it with a same type and number, as in the ace of ICs the related Ic, must be replaced. If only one Ic is uded for red, green and blue outputs, that Ic must be replaced.
If you need any more assistance, feel free to get me through Fixya. Ok.

Hi i have a Zenith z20la7r lcd tv.Leave it on overnight next day i notice a white appearance in the background of the screen and some color stream at the top. can this problem fix?. is it the board or


I doubt you will damage it unless black or bright blue on screen which could burn the image.

Before trouble shooting I would call Zenith (they are LG) and inquire if this is a known issue in this model and also if any software upgrades exist for this model.

Philips 42pfl7762D-lcd blue screen, remote control


Hi! I have the probably same problem (since today) - all I know is that it is because the TV is set to digital instead of analogue, and it won't allow me to put it back into analogue mode - when I try that, i get the cross you mentioned. The strange thing is, that there are no menus visible at all. But the volume and screen output format buttons are workijng and show on the TV. Otherwise the screen is blue. Any solutions?

For about 6 months there has been a faint gray/black verticle line running down the middle of the screen . is worse on blue/green backgrounds, and is almost not noticable on white backgrounds. I know that...


I've seen a similar looking problem and it is a bad LCD panel. It will show even on a non-used input, and will show through the menu screen and the screen saver, also. Sharp's LCD panels are very expensive,too. Over 4000 at encompassparts.
