Question about Philips 23PF5320 23 in. HD-Ready LCD Television

1 Answer

Horizontal Lines Moving Through Screen

Since connecting a HD-cable box to my TV, I have started to notice dark (possibly green) lines running vertically up the screen. The lines vary in thickness, depending on the program, and are even visible on the black screen when I turn the cable-box off. I have contacted Philips about having the unit repaired, but they have told me that I would need to mail it to Arkansas for replacement. I have read some horror stories about that, so I am reluctant to do it. Any suggestions?

Dark horizontal line scrolling up from bottom of screen

if you are using a cable box .. then disconnect everything that is feeding signals into the tv ... then get a signal from some other source (like off the air antenna or video camera) ... if the tv still has the dark lines then you have a bad primary filter capacitor in its power supply .. if it works ok off the air and only does it when the cable box is hooked up .. then the cable box has an open primary filter capacitor . ... the dark horizontal bars you see is ripple from the rectified AC power that is not properly filtered ... if the TVs verticle scan rate is 60 hz and the full wave rectified AC amounts to 120 hz ripple then you will see two dark bars across the picture ... since the two signals are not syncronized then they will slip in phase with respect to each other .. thus the constantly moving pattern ..

Slow moving lines up screen

I noticed the same lines on my 32" Sylvania LCD. After playing with some electrical plugs, I found that having my Sony PS3 plugged in interfered with my cable quality. When I unplugged the PS3, the lines and slight humming (only noticeable from behind TV) went away. I tried making sure the cable line and PS3 power cord weren't touching but to no avail. I guess I'll just leave in unplugged while watching TV.

Lines on the screen

Are they thin, white lines running east to west? If so, they are called retrace lines and indicate that the screen settings for the picture tubes is set too high or there may be a mal-function of the CRT driver circuitry. Try adjusting the screen controls which are located behind the front grill of the TV behind an access panel. Once you remove the grill and access panel, you'll see a small control assembly the has two sets of controls. Three for adjusting the red, green, and blue focus, the other, the red, blue, and green screen controls. To adjust correctly, put the TV on an unused input(dark, blank picture) and adjust until there are no visable retrace lines or color in the image.

Horizontal Lines scrolling on screen

I had a similar issue with my Mitsubishi HD 1080. My power supply went out, I had it replaced and it works like new. However, just today I had AT&T U-Verse installed. When the cable guy was showing me the new HD channels all seemed good. This evening (about 5 hours after being installed) I started seeing these horizontal lines across my screen. The picture was still HD quality, but those annoying lines just wouldn't go away. Anyway, after reading a few blogs on-line suggesting interference or bad grounding, it hit me!!! The AT&T guy who installed my U-Verse (cable, internet and phone) had set the modem on top of my TV!!! It was just starring at me this whole time. So I removed the modem off the top of my TV and put it on a side table just to see what would happen and sure enough the lines were gone!!! You may not have the exact same problem, but it may be some type of interference (cell phone, modem, etc, either on top or around your TV that is causing the issue... Hope this helps. Thanks.

Horizontal scan lines from bottom to top of my HDTV.

Hi There,

I stumbled across this when i was searching for a fix for the same problem, you're top hit on google for "LCD Horiztonal scan lines" :-)

Anyways, i had the exact same issue, didn't turn up any solutions on the web so i started troubleshooting, and i've fixed it!

My signal cable was running for approx 1metre right along side the 240v / 50hz (Scotland) power cable for the screen. When i moved the signal cable away from the power cable, the lines faded a lot.

Now i've routed the two cables seperately, and i have no more issues! Hope this helps you!

After a household power blips during bad weather, we have horizontal lines ....

Unfortunately there isn't any way to repair your tv as the magnet has distorted the tube that is in the tv and with CRT becoming obsolete the repair is likely to be very costly so probably your chaepest option is to buy a new tv .

Horizontal Lines

sounds like you are seeing retrace lines. you will have to adjuste the screen control. (it would be like a master brightness.) you will have to removed the front bottom plastic from the tv, look for 2 to 4 screws. then gently remove the front. sometimes the also add velcro to help hold it in place. now you need to remove the small plastic or wooden panel/door. in the upper right side you will see a small box with 6 controls.i do nor remember if the top 3 controls are for screen or focus, use a flashlight it is marked on the box which is which. adjusted the screen control to the left slightly to decrease the color you need. the green is the center control. like you said it is more noticable on dark screens, so try & adjust it in a dark romm with a drak seen. good luck.
