SOURCE: Thick color lines on screen

Hi ,Sorry, this is not a solution. I have a question about your line. Is it transparent? (can you see through if the picture is bright)Does it remain there all the time if you change inputs? My LG 42" just had a blue transparent line appear on the right side of screen. Tried a few trouble shooting things w/ no change. About 1 hour later it went away. Did you find a solution and what was it?

LG 50PK550 Plasma Single Thin Green Vertical Line


It is going to be one of two basic issues:

1. There is a poor connection somewhere in the set--either with a plug or cable or on one of the boards.

2. There is a board that is beginning to fail causing this.

Either would require a shop and may or may not be worth the cause.

Having seen hundreds of these sets all are more prone to flaky problems than the older sets and average life span is 3-5 years.

Shop I work for 80% of them are 2 years old or less.

If problem began shortly after set was moved or relocated I would lean towards a bad connection somewhere.

Samsung 50 in. HPS5033X/XAA colored lines running vertically and won't go away.


How wide are the lines. Do they change width? Where on the screen are they located?Connections on the c boards at the bottom to the panel flex cables or bad c board itself can cause 2 inch wide verticle bar. Before touching these connectors be sure power supply is disconnected from the 2 sustain boards on the sides. If you don't there will be an arc that will destroy the flex cable thus you will have to replace the panel. If C boards or connections don't fix it the replace the plasma panel. If the lines are thin lines then panel is likely bad. Contact Panasonic even if out of warr they may help.

I have a verticle black line about 3 inches wide on my panasonic


Normally when a line appears on the screen of a plasma or LCD it indicates the TV needs repair. There are circuit boards inside the set that, if bad, will cause problems with the picture. The only troubleshooting the manufacturer will offer is to unplug the TV for 30 minutes. If that doesn't solve the issue, the unit needs service.

Call Panasonic at 800-211-7262 to see what they're willing to do for you. If you're under warranty they will service the TV for sure. If you're out of warranty they still might give you a break--they've been known to do that.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please post a comment if you need additional assistance so that I can help you further.
