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

1 Answer

Graphics are cut off.

No matter what I do with the convergence my picture is cutting graphics either on the top or the bottom or even the sides of the screen. I tried every aspect ratio and failed. For example, any bottomline wheather its news or espn, I cannot read the scroll entirely. If I were to bring the picture up a little, then I cut the graphics on the top. If I were to move the picture to the left, then it becomes tilted. Every other TV in my home doesnt have this problem. Can anyone help. Thank you.

SOURCE: Graphics are cut off.

First, have you made any adjustments to the tv other than from the setup menu? If not I have the service manuals for the tv in pdf files and would be glad to send them to you. Let me know I have the same tv and corrected the same problem. v/r, Scott

How to replace convergence ICs in samsung

You will need:
  1. Convergence ICs.
  2. Heat sink grease or thermal compound.
  3. Soldering iron.
  4. Solder lead.
  5. Digital multimeter.
  6. Solder pump.
  7. Small side cutter.
  1. Unplug the unit from the AC outlet.
  2. Remove the screws and take the back panel off the TV. The convergence ICs are located behind a large heat sink.
  3. Remove the board that the ICs are on.
  4. Check all the big resistors on the board using the digital multimeter. Some resistors are connected in parallel so they read half of their nominal resistance.
  5. Check the board for cracked solders and tracks.
  6. Cut all the legs of the ICs and unscrew them from the heat sink to take them out.
  7. Remove all the legs by applying soldering iron on one side and pulling on the other side.
  8. Clean the holes for the new ICs with the soldering iron and solder pump.
  9. Clean the heat sink from the old thermal compound or grease and apply the new one to the ICs.
  10. Fit the new ICs legs on the holes and screw them to the heat sink. Wipe excessive grease. Make sure they are making good contact with the heat sink.
  11. Cut excessive length of legs. Leave about 2mm and solder it in.
  12. Clean solder points with lacquer thinner or even alcohol.
  13. Make sure no solder is going to two legs at the same time.
  14. Put all back together.
  15. You may need to readjust the convergence on the menu.

My TV picture cuts off on the top and bottom

Check what format you are in. 4:3 is like a regular tv. Sides will be cut off in this format on a widescreen tv. 16:9 zoomed will cut of top & bottom slightly. You want just regular 16:9. No zoom.

Sounds like you have a convergence problem and the set will require repair. This repair will run somewhere around $400 if you have a good company complete the repair for you.

If you are interested in doing this repair yourself you will need to be able to use a meter and solder VERY well.

If you have more questions please email me.

Thank you,

Projected image is too large for screen

Good Day Brian;

The warped, too large picture is the same problem, the TV has a convergence problem. ln today's electronics the first thing that should be done on any electronic device is to, reset, unplug TV from the a/c outlet for at least 4-5 minutes then plug back in. If no fix; Your TV has a circuit problem. RCA has three common problems that could cause this condition; the most common is a fuse near the fly-back, IH-VT, the convergence power board or the signal board.

Always, call a factory authorized service dealer if you are not familiar with repairing electronic equipment that contain HIGH VOLTAGE, just for your own safety.

Good Luck, Big Irish.
