The yoke needs to be turned slightly and the picture will move in the same direction as you rotate the Yoke. (located on the neck of the Picture Tube) Just loosen the screw on the yokes clamp slightly then carefully touch only plastic edge of the yoke and turn it slightly while an assistance watches the picture be careful not to slide the yoke up hugher or lower on the neck. It has to saty at the same spot but just rotated slightly.The pic below shows the yoke with yellow arraows. Do not disturb the purity rings (RED ARROW) or it will cause blotches in the picture so its very important not to disturb the item with red arrow.
This is usually due to a leaking CRT. Or picture tube oxidation in the cooling liquid. Definatly not a job to be performed in the home. The cooling liquid needs to be changed in all three picture tubes. Cleaned inside the jugs and replacement gaskets. Gennerally about 60 to 85 dollars each. often, the fluid leaks onto the power supply or sweep module and causes other problems.
Got the same problem with same TV (PT-61-LCX65) that was bought 4 years go in 2006 - first red spot appeared, then few weeks ago got green one nearby. Fixed it for free.
I called Panasonic using the phone number in the manual (1-888-843-9788), selected Service, told that I got the problem which is most probably "a manufacturer's defect" that should be fixed for free - they redirected me to next step, then to next one and in about 20 minutes they arranged me a home-visit by support person (the guy had to drive 2 hours to get here!). Every thing went _very_ smoothly, I am very satisfied with Panasonic's support, it was just one call with few redirections.
The service guy came in two days, unscrewed back panel, connected some kind of box to one of the boards (eeprom programmer?), turned TV onto some channel and let the box do its job for about 5 minutes - then all of a sudden spots disappeared and picture is OK now. The service guy told me that the overall picture quality should have also improved all across the screen, I guess TV sends some kind of feedback to that box for optimization.
It was free service, the service guy mentioned something about law action and that Panasonic is required to fix that for free.
you may have a short in the picture tube. but from your description it sounds like the positor has failed. really hard from your description but if the positor has failed its very cheap to replace..farr64
Smoking absolutely destroys these TVs. Just like Teeth, the smoke gets inside and permenantly yellows the Light Prism. Since the Light Prism is responsible for passing light in these units, the yellowing dims and yellows the picture. There is NO fix for this.
Cleaning these is dangerous since all the parts have either a UV or Polarizing coating on them.
Again, I am sorry but this is the truth. On the other hand, try pressing the "Video" Button to see if one of these settings is any improvement
The problem you have with the picture is a problem with the video circuit. Most likely a coupling capacitor or the Y/C Video Jungle IC. the half mood on the picture could be a seriuos problem though. You will need to take off the front screen and while the set is on, look down all three picture tubes. Is there what looks like a spot on one of the pictubes surfaces? If there is, that tube is going to have to be replaced. If it looks like something floating around inside the tube, maybe the tube can be disassembled and cleaned.. Also check the mirrors inside the set and on the surface of the three lens, maybe there is a spot on one of those. Good Luck.
It probably has a broken mirror or somethings inside the set blocking part of the pic. Now for ther picture all red. If your not a tech I highly advise you going insidew this . Unless you know about the saftey issues and the HI voltage issues. Your problem could be a shorted Picture tube all the way to na bad distribution block . Good Luck
