Pioneer Tv SD-P4553

We have moved this tv a few times and now we have a black bar acrross the bottom of the screen, seems like the whole picture has shifted, is there a way to re-align this without a technician. I have tried changing the convergence settings.

You have incomplete vertical deflection at bottom of screen. Replace C155(2.2uf@16v) on video/deflection assy. Use part number ACH1131

Dvd's aren't fitting my screen, the sides and top/bottom is being cut of. I've tried the display menu, zoom, and making it widescreen, and it doesn't work.

Are you playing wide-screen movies on a 4x3=1.33:1 (standard=SD) TV? DVD output by default is SD. Even 16x9=1.78:1 (HD) movies with have top and bottom bars. Many "wide-screen" DVDs are squeezed horizontally so that you have to stretch them. Many theatrical releases are up to 2.7:1 or so. Side bars indicate you have the DVD output set for 4x3 and your TV is HD-like. There are usually controls for the screen format on HD TVs--no controls on SD TV. Hey, early movies were 1:1--take them side bars. More on aspect ratio (AR) in Wiki, I bet. With letterbox of SD you can get "pillar box" with black on all 4 side. Get a better source and/or choose a different AR. -Ken

How to remove front screen

The screen comes off from the front. First take off the speaker grill and you can access the frame screws they are right below the screen. This only takes off the frame with the filter. After the screws are out swing the bottom out a bit and lift straight up on the frame then pull it out away from the set. I have found these to be very stubborn somtimes, but you should be able to get the frame to move then work it up and off. I hope this helps you. let me know if you have any more quesitons.

My Pioneer 55 inch screen tv SD-P5553 has a solid black horizonta

This sounds like a picture mode issue. You maybe in a ZOOM mode. Try adjusting your set to FULL mode. If you are using a Sat receiver or cable box, some of these may have picture viewing mode as well, wich may need to be set in FULL or NORMAL viewing mode.

Good Luck!

it has to be repaired.
