Dear Sir/madam,

Panasonic is well known for their cold
solder joints on their circuit boards.
A component soldered onto the circuit board has a bad solder
connection. When you pound on the cabinet, the component
will achieve connection (now and then).

To find this anomaly, you have to take the back off the set and
access the electronics in the cabinet.
Turn the set on and use a non-metallic wand (wood or plastic)
(and not a pencil) to probe the boards. Since the problem has
a relation to the deflection circuits, I suggest probing the
deflection boards. When you find a "sensitive spot" with your
probing (the picture collapses and returns to normal size), mark
the spot.

Using a low heat soldering iron and a good 60-40 electronic
solder, resolder the connections on the circuit board at the
sensitive point.

Since the cold solder joint will not be readily visible, you may
have to do this two or three times until you finally hit the right
spot.



Thanks
good luck

Ive got a line down the left hand side of the screen when the tv is turned on the model number is panasonic viera tx-p42v20b


HI,

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER

GOOD LUCK IN RECTIFYING THE FAULT, THANKS

Tv screen is black except for 1 horizontal line of color


The line is there because the vertical deflection unit - the one that spreads that line across the entire screen to form the image - has failed. Replacing it is a job for a professional, or at least an experienced amateur, and the parts will be quite difficult to find for such an old tv .

Green line in middle of tv when switched on


Is there a picture with the green line going through the centre. If it`s just a green line with no picture, it sounds like the Frame (Vertical scan) Output IC has failed and possibly the safety feed resistor near the LOPTX. The reason why it`s a green line is to protect the tube from phosphor damage. The older TV`s would produce a VERY bright white line across the screen which could burn the phosphors withing the tube if left turned on in that condition. It`s not an expensive repair, but is it worth it with the price of Modern TV`s nowadays. If there is a picture with a green line, it may be due to phosphor damage, in which case, it`s a new CRT (tube). Ian

Intermittent 3 inch green vertical line-5 inches from right side


it you have a repair skills you need to open the TV and make sure all the ribon connectors around the circuit boards are proper connected
and if all seems to be ok, the DG board will need to be replaced.

If you dont have any repair skills I would recommend you to take you TV to a repair shop since this is complex repair

Panasonic - Poor Picture Quality


There can possibly one problem. If you check on tube bords. There is a white plug that plugs into the tube. If you carefuly open that white plug, there is 2 silver contact point, called the spark. clean it with benine., but it must be clean. If you have to use small peace of sand paper ok. But afther that use clear Q-Tex (for Nails) and cover points. Let it dry and set will be ok.

Thanks
