New Convergence board but need help adjusting convergence still

I have a Samsung hcm5525w that was having convergence problems so I bought the sub definition board because I didn’t want to deal with the soldering or if it was the fuses or amp that could have been bad. Anyways I put it in and am still having some problems with the red convergence. I only have a universal remote so when I use the key functions for the convergence screen (mute 1-8-3) I can adjust it back to place but I don’t have the (auto focus) button that saves the adjustments that I just made and have to turn off the TV to get out of this screen. Any suggestions?

    I replaced the board part number AA95-01846D i thought this was the convergence board? If thats not it and i need a new convergence board what is the part number of the board i need and where can i find it? Thanks for your time and help

    Thanks a lot for all the help. I'm just wondering if I even needed the sub def board in the first place?

  • amroller503 May 26, 2008

    Before I buy the aa95-01799g convergence board part I just wanted to make sure the problem was completely understood. when I go to the mute 1-8-3 screen i can adjust all the red, blue and green back perfectly but my understanding is inorder to save it i need the auto focus button that is only on the factory remote, not my universal remote. should buying the convergence board automatically fix the problem or will i still need to adjust it and save with the original remote?

If the new sub board didnt fix the problem you will need a new convergence board as the sub deflection boards with the ICs only powers the convergence board. thats a complete seperate board. Let me know if you need more assistance.

Ghosts


How old is ur tv...? Cos the wear & tear is the cause for this ghost appearance. The repair for this is only temporarily. It can not be eliminated completely.

Generally the blue ad yellow colour can be removed by a tool which is available with a tv technician. It is not very expensive to do this. Hoping to hear from you.

Thankyou

Right side ghosting problem on the screen


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

Samsung HCM5525W - Picture pulses slightly


It sounds like a filter cap is out or a resistor has gone o/c. check the circuit around the sub deflect board and anything that feeds it sometimes when convergence boards go they also take out a smaller component that is linked with the deflection. In this case the capacitors need to be tested or looked at for any signs of venting.

This is a convergence problem. It happens to all big screen rear projectors. The convergence output ic's need to be replaced. I would let a repair man do this.
