    Thanks for your reply Computes. The link says identifier invalid. I have the service manual but no mention in it of the ID settings for my 34XBR800. How did I get here? Well, the set wouldn't come on and diag showed 3,6 blinks. Changed the two MCZ3001D IC6501 & IC8002 on D Board and TV came back on. Then got over-ambitious and don't know exactly, but I think I went to RAMW and set it to 1 and also reset data 7 > Jump > Enter and did a copy on CXA2170D-4 item 6 and D-Conv item 13. Lost width/zoom control button and a couple of settings on the TV menu, but more seriously, related or not, have H convergence on the outskirts of the picture only and LSAP/RSAP do not work. Managed to find out by trial and error that ID7 set to an odd number, like 1, does thetrick and the width/zoom control comes back, but have not identified if the outside convergence problem is related to ID settings or some hardware fault.

    Do you have the ID codes for this model? Where did you get them?

I don't know what he did after, but it sounds like he started with the same fix I did----->Go here
for my post #108 for a step-by-step solution with pictures. $21.83 is all it cost me. I fixed my own TV as many others on that forum have. Feel free to contact me at if you run into difficulties.
P.S. There are codes listed near the bottom of that page of posts. I hope I have helped.

I would love to know the original problem, and what you did exactly so far. If you change any data I suggest you write down the original numbers, or the set may become unfixable. If you check the data use the 4 key to start at the bottom and confirm that the ID codes are correct for this model. (ID1 = ID2 = ect)
You can download the complete Sony manual with this link I made, and open it with any Adobe PDF viewer.

What is cost of yoke for panasonic ct tv?

You're discussing about the width problem to picture. If yoke have a short in between its wingdings [even a single winding short], will cause the failure of horizontal output transistor. As per you report here, the set has a raster, but problem is with the picture width.
There possibliliites for this fault are.
1. Lack of voltage from the SMPS power supply output.
2. Horizontal width capacitor.
3. Horizontal output capacitor.
Check the output voltage from the SMPS section first, and confirm that it is OK.

Sony kp-46v15 convergence problem dont know were to start on adjusting main convergence board in front were do i start there is 15 or so red green blue ajustments for horizontal and the same for vertical...

Do not mess with those, they don't just go out. they are also for skew linearity, heighth, width for vertical and horizontal adjustments. If your convergence went out need to find convergence circuit and look on the plugs for your vcc voltages going to the convergence circuit. If missing, trace back to power supply and look for an open low value resistor.

Picture bowing in center from top down about 1 inch in middle, ok at edges, also looks as if degause is inoperative with colors on left and right (purity) --------------------------------__________________...

This is a convergence problem. Look for poor connections at the convergence ICs. Try resoldering the pins on the ICs. If that does not resolve the problem, replace the ICs.

Correct overscan on kv-34xbr800

With TV off, enter the following on your remote:
Display > 5 > Volume + > Power now you are in service mode 2 & 5 will take you up and down categories 1 & 4 will take you up and down settings within categories 3 & 6 will change the data up or down
So press 2 until you come to the 2170D_2 category Press 1 until you get to HSIZ and change the data down to the required setting (different data registers for different width settings)
It could be more involved but this might do the trick in your case. Good luck!
