If convergence problem color would be bowed and off. If it is the convergence replace ic stks there are 2 inside tv if you could solder and good at this stuff. parts cost is 30.00 . if you are going to get fixed cost is 300.00 . www.part store.com has parts just give them model number .They can tell you part number.I would pay someone to do this it is trickey.

I think ghosting is ground problem on cable connections check connections and replace cable wire.

TV rca hd 52w59 has convex picture. can I fix it.


If convergence adjustment did not correct the problem likely the convergence IC's have failed and will need to be replaced along with a few defective resistors in that circuit. If you have never attempted TV repair this would not be a good repair to start on.

The only way to be positive of the problem is to have the circuitry diagnosed by someone with the proper TV test EQUIPMENT to determine what parts that are no longer within specs.

I have a 50FX20B Hitachi where the color has split up and there's some form of ghosting. Could this be caused by a video card or video board if one are in there.


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded over.

Samsung tv model # HCP4363WX Ghosting


The convergence board that you replaced will not correct the issue that your describing as your model has the convergence amp circuits located on the Deflection board. You would need the deflection board which is available at the following link. It also has a picture of the board which is in your model its the large board on the right with the Flyback and both Convergence ICs on it.

Hitachi, model 57UWX20B ghosting?


The most likely cause is shorted convergence chips and possibly a few pico fuses.

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. This is called convergence.

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,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with 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 - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Ghosting and distortion


You can buy just about anything you want on-line by searching.
 The convergence amplifiers are large, 2 inch x 3 inch IC's that
 are mounted on the largest heatsink(s) in your tv.Some Samsungs mount the convergence amp board up high,above the
main chassis (easy pull) or down low on main chassis.The part
number is Stk392-040.Change both for reliability.I use panasonic
brand  = never had a call-back failure yet.Reset alignment after
changing IC's. ..........T.
