Most times when that models Convergence ICs blow they take out at least one of the resistors on the board right next to the ICs. They are easy to spot there are about 7 of them they have no color bands and they are all identical either light blue or light green. Look at those resistors you will no doubt find at least one maybe two that are open. they are rated at 2.2 ohm 2 watt and at 5% tolerance this is marked with a J on the resistor. Let me know if you need any additional help.

Hitachi 50SBX78B Horizontal lines and bow

John, Hitachi site is down at the moment, if you remove the clips on the front of the IC`s you will see the numbers of the convergence ic`s, and yes they are a pain to get out, they are probably stk 392-110`s if they are the originals, you`ll have to un-solder 36 pins total to get them out, check for burnt resistors in the general area of the ic`s and replace any that are burnt before turning the set on,be sure to order a tube of "heat sink compound" to apply to the back of the new IC`s, once on the set will probably still look poor, this is normal, run the set for minimum of 15 minutes then push the " magic focus button " inside the front door panel, after it has finished running magic focus it should look great, video-tek

Samsung HDTV 1080I-Model#HCP4363W-Convergence Problem

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

Horizontal Curvature with convergence problem

DA, convergence circuit has failed, the IC`s and possibly a couple of support resistors need to be replaced, your right about it being a good set, 6 years is about average for convergence IC`s, call your local shops for a few estimates and get it fixed, it will run for a lot longer than 6 years, hope this is the advice your looking for, e-mail me if you have more questions, BMW Rider

Right side convergence

A convergence IC has burned out. If I remember correctly, those Pioneer sets have one huge convergence IC, but that IC only has 5 channels in it so they use another smaller dual STK IC and one half of it is used for the 6th channel and the other half is the vertical output. Look on the convergence board, find the blue convergence jack, identify the blue horizontal channel, follow the traces and replace the IC handling the blue horizontal channel.

Your problem is a bad main filter, a regulator IC ,and or a combination of a convergence problem along with a vertical IC going bad. This set is not something you should mess with unless your a trained tech. Please seek a pro to assist you with this repair. good Luck

Distorted Color and geometry of Picture

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.
