Question about Panasonic PT-47WX49 47" Rear Projection Television

7 Answers

Distorted Color and geometry of Picture

I have a PT-47WX49 rear projection Panasonic TV that is 4.5 years old. When I powered it up yesterday, the picture came on with a nonuniform distorted appearance. In general, the picture appears to be misaligned with a blue shadow on the entire picture. In addition, there is a blue semicircular area at the bottom of the picture with a red semicircular shadow above the blue area. It is impossible to align the blue and red using the convergence functions as different parts of the picture are out of alignment in differing amounts. Finally the geometry of the picture appears to be distorted in the blue and red semi-circular areas at the bottom of the picture.

    I have the panasonic pt-61sx30cb. In addition to the distorted color and geometry of the picture, it seems the television cannot stop from switching between 4:3 and 16:9. It constantly flickers like it cant choose which format. then it straightens up. It also will stretch the picture when its acting up. example if im reading subtitles they stretch right out of view.

    I bought this 53SBX a few yeas ago, it has the red distortion as yours. Magic focus could not fix it. Can we adjust some button to fix the problem?

    And if it is, then where ?

    I have a phillips\magnavox model# 60p8241 57" in general the picture appears to be misaligned with a blue and red color and the tint seems to be real light. I have adjusted the color just a little but the overall picture is still not clear.

    when aligning the blue moves fine but the red will not move side to side

    Same problem. Distorted vertical geometry. So bad you cannot read the menu if you try. Only about 3 years old and put in a brand new replacement lamp just a month ago after a month long warning that the lamp was about out. Cost of the lamp was $225. This will be my last JVC. Model is JVC 52z575. Called the cable guy who had me restart the cable setup to no avail.

    I have the Panasonic rear projection model TX-51P400H and am experiencing very similar problems. The convergence cannot be adjusted successfully with the remote and I still end up with a best result of a reasonable image on the centre of the screen with the three images (red, blue and green) on the perimeters of the screen. A technician friend replaced the brightness capacitor as his past experience on crt tvs indicated that this can effect convergence, but this fix was unsuccessful.

    I cannot adjust the lens given in the crosshairs. the lens will move vertically but not horizontally. The picture suddenly went out of focus and I have fixed it before but the lens will not move now, see first sentence.

    I have the same problem with my Sony projection TV. It looks like your wearing 3D glasses. I was told to have someone look at it it was $100 plus if it is the convergence it'll be about another $350. Any ideas on a eay fix? Sony had me try a few things, but it didn't work.

I've posted this solution several times but here goes. Try setting up the convergence through the menu by accessing the convergence setup menu. If this fails to work you have a bad digital convergence box and need a tech to replace it. About $60 to $100 fix.

Panasonic rear projection TV 47 in PT 47WX49

Camaroguy: This exact problem happened to us about 8 months ago. A board had to be replaced at a cost of $500. Yesterday, the convergence has gone on the set. You get a blue and yellow shadow on the picture. From what I have been reading, this has happened on a few TVs and it will cost another $500 or so. We refuse to pour more money down the drain so we just went out and bought a new plasma (RCA) for half what it cost us for the Panasonic 4 years ago. We have never had a problem with RCA in the past (two tvs for 20 years a piece).
