First reset the settings to factory default. if that doesn't help and you also have it on the title (splash) screen, one of the ribbon cables for the lcd panels may be loose. you'd need to remove the cover and reseat the cables.

I have RED verticle lines all the way across the screen fro top to bottom 10 minutes after I turn my Panasonic PT-52LCX65 TV on. Is there a solution?


Hello
Check and replace the main filter capacitor in the power supply section. Replace all of them in the secondary section of the power supply too. The problem is due to insufficant smoothing and regulatio fo the power supply section. If main smoothing capacitor gets value deveoped, it won't supply enough voltage to the switching section, and switching section also will go inefficient. Replace all of them. It won't cost not much. OK.

Panasonic PT-AE900u Horizontal Ghost Image/ 2:35 Image Retention.


It sounds like an Intergrated Circuit (IC) has fried. Even on a good day, this is not something you can attack at home. As a tech (and as an owner of that model samsung), I'd need a map & tools to know what's going on. Your best bet in this situation is to contact Samsung and let them recommend an authorized service center in your area. Sorry I can't be of more help, but this is a rather serious problem.

Pt-47wx49e convergence problem


I just replaced the 2 convergance chips, but it did not seem to fix the problem. I then tested all the resistors that feed the convergence chips anf there was a 2.2 ohm fusable blown. IT was R7050 on mine. That seemed to fix it so that I could adjust all the colors through the convergence 2 screen. There seems to be a slight bow near the bottom when you look at the c2 screen, but not noticable when you are watching a picture. Since I got this broken, I am not sure how perfect it should be.

If anyone can send me the service manual, I would appretiate it. Thanks.

PT-47WX53G green convergence and wave on bottom of screen


Had same problem with Red. Could not adjust. Funny broken lines. Found this link:

http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.html

Replaced the ICs. Was disappointed at first 'cause it was still all bowed out, but then realized that the Convergence 2 "target" can be changed with the number keys. Working thru 1-9 and going back to readjust as necessary adjusted each one into perfect alignment.

Problem solved. TV works great.

I should add that while I am reasonable technically adept, I am a software geek and never soldered before... hardest part was getting up the courage to dive in and do it myself. Glad I did.

Blue line trouble


Hi Kracka,

Are you able to post a picture of the problem?

It sounds from your description that it might be a 'convergence' problem which is when the red, green and blue parts of the image aren't alligned properly.

Check in your menu to see if there is a convergence setting.

Hope this helps
