Hello

Your TV may have focus problem. If the focus pack of the TV [which is usually integrated with its Line Output Transformer (LOT)], may faulty. It is a rare case. In most similar cases, the CRT socket, connected on the base board of the TV may get damaged, due to this proper focus voltage doesn't reach to the respective pin of the picture tube. You just replace the picture tube base socket with a similar new one. In most cases this will retify the problem.

Coloured lines down the right side of screen


if the lines extend top to bottom and are thin, then the LCD panel is most likely defective.

Coloured lines down my tv


If the coloured lines are in the edges, then there is absolutely no problem and it should not be visible from a viewing range of 1.5 meters and further. If the lines are in the middle of the screen, then your phosphor coating (the screen) is burnt. you need to buy a new one, since burnt screens are not repairable.

A line stright down the screen


Scuse me
you can't do anything for this because if you have a defective anode or cathode on your cluster screen you will have what we call a dead-line (anode = Oriental , cathode = vertical)

but if your warrantied is not finish go for it it's your last chance

bye and sorry

26PFL5520D/50 DVT PROBLEM


If the lines across the screen are made up of coloured blocks, then the problem is likely to be a weak signal.

Digital channels are broadcast in groups called multiplexes. Sometimes one multiplex may have a weaker signal than others, and so you experience problems with up to 6 channels when all others are ok.

If it is only one or a few channels then just wait and see what happens, because it may be transmitter works.

If you have problems with all channels it could be a connection or antenna problem.



If the lines are just straight lines, then try resetting the TV as follows:

Switch on the TV

Press and hold the menu button on the side of the set. The settings menu will appear. Hold until the menu disappears again.

When you release the button, the TV will take up to about 90 seconds and then reset.

The TV will then show the original screen when the TV was new.

Press ok when shown.

Set language and country settings.

Move down the list and press ok to re-install all channels.

Line across top of screen


If the picture is ok otherwise then only thing that probably needs to be done is a vertical height adjustment. That is if the lines never changes position from cold to hot.
