KP-51HW40 - Picture not Clear

I've had my sony KP-51HW40 now TV for 6 years without a problem. It recently went grossly out of allignment (of so it seems). The image looks like a 3D immage (without the glasses on). It does appear that all of the CRTs are working. The flash allignment function does not help. Any suggestions how to re-align ? ? If I call min a pro. any thoughts on what this repair should cast ? ? Thanks in advance

    Sounds like a solution.

    I don't have much TV experience but can usually fix just about anything else. What would be the first step in fixing it myself ? ? If you think its too much for a novice what should a repair list this run me ? ?

    Thanks for you reponse. I really appreciate it.

    I purchased two new STK IC to replace the existing one. Other than swaping the conv. amp IC's is there anything else needed to resole the convergence issue (e.g. other component replacements, re-allignment on guns, etc,)

    I what to make sure I address the entrie issue.

    Thanks

Your problem is a typical convergence problem that happens on almost every tube type projection TV set ever built. There are two Convergence amp IC's that need to be replaced. If you have no TV repair experience, play it safe and call in a pro to assist you in this. Good Luck

My KP-51HW40 is better, but it still turn itself off


Are you sure you didn't turn the knob too far down? Just a though. I don't know off hand which one is the D board but the boards are marked. Please be careful when working on TV sets as they produce high voltage which may reside even while the sets is unplugged. Also I would do more research on this problem before purchasing a new D board. I have been told that the picture tubes in these sets go bad. G what a bummer guess what set I own :( Here is the code for 8 blinks, it looks like you may just have to replace a part on the D board.

8 times, Diagnosis: High voltage error. Possible cause: T8005 is faulty. (D board)

I hope this helps, keep in mind its hard to diagnose issues without actually being there.

Picture cutoff


if you are using a cable box or satellite,make sure those are also set to full mode..If tv only receives normal (16:9) etcc..then it will only display that..moset sources nowadays also have a picture mode ...

Video inputs


How is this distorted? Does DVD only have Video/Audio jacks or do it have RF output connection and if so have you tried going inset that way? How does it looks with only Dvd Logo on? If Logo is ok then I would look for some other problem.

Picture Quality


without seeing a picture I can guess that you may have a shorted green crt or the drive going to it has changed and you may need to turn down the g2 control for the green. If the tube is shorted or bad see what type of warrantee you have on the crts as some sets have two to 5 years. Good Luck
