Samsung HC-P4252W convergence problem

Hi

I recently had this model as a broken gift. It seems the blue lens is way off. I have entered the MUTE 183 code and couldn't do much. I'm posting some pictures of what it actually look like. Is there any way to re-align the lenses ? Thanks. Pressing the focus button in convergence mode works, but doesn't help much.

    could you post back the link please ?

    In the MUTE183 menu, I could sucessfully move the red and green grid
    both vertically and horizontaly. The problem comes from the blue,
    because I can move it Vertically but can't move it horizontally with
    (vol+/vol-).

    Do I really need to change the ICs ? is there a need to solder them or something, i'm a complete noob when it comes to electronics.

    Thanks again !

  • Mizujin Mar 29, 2008

    thanks, I will open the back and try to look for theses pieces number. I'll then try to train myself to solder hehe

  • Mizujin Mar 29, 2008

    could you circle in the place I need to look ? there's a bunch of stuff in there. Are those aluminum things the heatsinks you are talking of ? thanks !

    My mistake, I see one of them directly on a heatsink. there are screws and white paste under it. model is a STK392-010
    I can't locate the second one.

  • Mizujin Mar 29, 2008

    Ok, I have located it. Should I remove them now ? or order the 2 pieces and wait for instructions ?

  • Mizujin Mar 30, 2008

    Hey again, I have ordered the two IC's and now i'm gonna train at soldering. I have noticed two VR-semi (RR402S - RR47S1) that are burnt and was wondering if thoses are the two main resistor that burns with the IC's. Should I look for other resistors ?

    Thanks alot for your help

You need to change the convergence ICs. This is an inexpensive repair if you do the repair yourself. The ICs are located on the big heatsink they should Be STK392-110 or 120 or else they could be STK 392-010 or 020 . But what ever STK number you have you will need to replace both. Here is a link where you can get replacement ICs and they include step by step installation instructions with the new ICs. Here is their link.

    Sorry the link didnt post here it is again. And yes they need to be solderd in, however if you purchase the ICs from this link they do provide complete step by step instruction with the ICs and also offer free support to help you should you have any problems. I am one of their support tech as well as a partner. We set up email accounts for all our customers for free support. Its an easy repair takes about an hour from start to finish.

    They should be right there near the outer edge on the board on the right on either one large heat sink or two large heatsinks right next to each other.

    Sonny Berry Mar 29, 2008

    I tried going to the link but it wont take me there could you post it again and i will circle the location of the ICs for you.

    Sonny Berry Mar 29, 2008

    Thta sthe right one. I believe that model has one heat sink right at the back and the other one is right next to it going in the opposite direction if I am not mistaken.

    Sonny Berry Mar 29, 2008

    Thats up to you. If you order them from the link I mentioned they will email out the instructions as soon as you place your order so if you need anything else at radio shack such as desoldering iron and what not.

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

Samsung HC-P4241W Convergance problem


press mute 183, if it isn't 183 it's 138.   You will see a large grid which you get the fun of adjusting, it's tedious as all get out! Enjoy!

Yes the HC-P4252W and the HC-P4752W are both P59A chassis so they both use the two STK392-010 Convergence amp iCs that are located on the sub deflection board

Convergence issues


if youre having convergence issues with your samsung HC-P4752W you need to replace both convergence ICs numbers STK392-010 they are available at the following link and they provide free instalation instructions with pics so you can do the repair your self and they also give free tech support in case you need extra help. Its an easy repair takes about an hour from start to finish, Changing the convergence board wont help as the Convergence ICs are located on the sub deflection board and thats about 400 to replace the board compared to 50 to replace the ICs. Heres the link.
