    I have the same issue and need to known how much it would cost to have this repaired? I think that this TV was poorly built seeing it only lasted 4 years before this issue arised.

    I have the same problem but have figured I was ready for a new (non-rear projection) set anyway. If there is an easy and cheap fix for the problem, I'd love to know about it as I would much rather give away a working set rather than contribute to the local land fill.

    I agree with the last post. This TV sucks! After spending $1300. on it you would THINK it would last a little longer than 4 years. Sounds like this problem is common and I wish Panasonic would stand behind their product. I guess that is what happens when everything is made in China.

Sounds like you have a blue foldover in the convergence. Since tv has been worked on it could be bad ic, maybe not original, generic. I would say if you can open set and look in, look for the blue it should be marked. look for a loose connection. If you can have someone to gently tap around that blue amp and see if it moves are go away, it might be a simple loose connection and needs soldering. If not then my have to change ic again. Becareful cause set would need to be on to really check. Hope this helps.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

What you will need to do is convergence. You can get a repair kit from TvRepairKits.com . It includes replacement parts,step by step instructions, support, etc.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

You are on the right track. The problem is actually with the green convergence IC that controls the alignment. The convergence ic's take the information from the 3 pictures and align them into one picture on the back of your screen. Although this is an economical repair it is complicated and should be left to a quailfied service technician. If you are not sure of a local technician, panasonic's website has a servicer locator that can guide you to one. Hope this helps
