YOu have convergence issues. Ok first question. IN your setup menu do you have the convergence option/ if you DO not then it can be a specail fusable link. fl231 if you do. next question do the picture bow in at the middle. if you do then it possibly a convergence power supply issue. next if you go into setup convergence does the crosshairs adjust up or down left to right on both blue and red. I if so then theres is a chance that it can be a convergence adjusment or a amplifer problem AS always THIS SET CAN GENERATE LEATHAL 380 VOLTS EVEN WITH SET UPLUGED SO BE CAREFULL.

PANASONICV that now has a "blurred" screen. We can see the channels but it looks like it's has a shadow around the images. The screen in in a red hue with green blur. TX-51P100H 51"...

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from and do the repair yourself. Its a fairly easy DIY fix.

Hello, I've got red wavy lines across screen

There are two common problems with these sets.

Problem #1) Convergence

  • Screen Looks 3D
  • Colors wont align
  • Video may look distorted
Problem #2 CRT Fluid has clouded over. Symtoms
  • Dull looking video
  • White looking video
  • Halos around objects
  • Red/Orange looking video

Red and green wavy lines

If the distortion that you see can be described as somewhat of a 3-D picture, the problem is teh convergence circuit and this can be fixed easily. Also, if you can solder, you can fix this yourself. If you wish to do this, please update this and I'll provide you with some instructions.

The lines you saw, i;m sure they are the ones called retrace lines but know the failure could be located on the red CRT board. Most likely the video amplifier is defective and not necessarily the CRT.
What is the model number of your TV?
