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

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!

50" Pioneer TV blacks out and has shadow on the bottom third

yes it is worth fixing.if you r getting it repaired for the first time.
but you will have to wait for some long time to get it repaired as the tv is very old its very difficult to get the parts for reparing it.

the problem what you r facing is the problem of the convergence in your main board of the tv.
it has to be repaired.
i will advise you to get it repaired as it will work.

for doing it your self you can try clicking this link and following the given instructions in it

Hi, your vertical section is beginning to fail, from your description you have a few electrolytic capacitors that are beginning to go bad, the correct term is they are "leaky", the set can be fixed easily by a tech, not so easy for a layperson because you don`t have the service manual or a capacitor analyzer. NOT an expensive fix, tech will have to remove board, unsolder some caps, check them and replace the bad ones, do a little touch up solder work and set is good as new, any questions? feel free to ask away, if not Happy Holidays, BMW Rider
