SOURCE: I have a Philips plasma 42 with black lines across the screen

I would first check if there is an available firmware upgrade for your model .Upgrade requires you to download firmware from philips website.Then transfer it to a memory stick .Then use a memory stick reader to plug into tv for firmware upgrade.Other wise the set would probably need repair .Possible a bad SSB board or another issue

The standard way to find out whether the issues on a tv are hardware related or settings environment related is to perform a reset to factory default through the menus available from the remote controlIf the fault persists after a reset and rescan the fault is almost certainly hardware related and will need the attention of a competent technician

Go to Philips web site, (enter Model number....) then download updated software & drive to update your TV software. It will fix that problem. I just did for my TV (42PF7320A/37).

My phillips 2006 hd tv has a black line across the screen with a snowy freeze


If you have parallel horizontal black lines on a white background, you can see the separation between the lines when it is viewed at close range (Figure 1). As you view the lines from further and further away,the image gets smaller, you eventually get to the point where you can no longer see the separation between the lines, and it looks like one line. Losing the ability to see separation in the lines is exactly what happens when you sit too far back from an HDTV set. If we apply the same principle to an HDTV, a 1080p resolution HDTV has to fit 1920 vertical and 1080 and horizontal black lines separated by the white space on the screen, (that is the pixel grid of a 1080p HDTV display). Furthermore the spaces between each cell of the grid need to be very small in relation to the area each cell occupies, or you will get a screen door type effect. A bigger HDTV can increase the size of the cells and the separation between the cells, so everything doesn't run together when you sit further back.

My screen has blue and red lines across it. Now the red lines are becoming stronger and the screen flashes red until it turns off. how do i fix this?


This is for if the lines are thin and in the form of an arc across the screen.

You need to turn down the screen voltage for the blue and red CRT. I believe the access is through the front on that model.

1) Remove the front grill
2) There should be access panel you need to remove once you remove the front grill. This is where the screen voltage adjustment is located
3) Look for a small black box with six knobs on it. One row is for "Focus" and one row is for "screen". It will be marked, but probably need a flashlight to see which row it is. There will be a "R", "G" and "B" next to each knob to represent Red, Green Blue respectively.

4) Careful with the access panel removed, you are only inches away from very dangerous voltages.
5) slowly turn the R or B knob counterclockwise until the lines on the screen disappear.
Keep your hands away from everything else and only use one hand near the tv. put the other hand behind your back.

6) Once corrected, replace the panel and put the grill cover back on.
