When adjusting the convergence, ended up with a concave screen, then it smoked. Is this a power supply, or worse? Is there any advice that you could give me on this...


Thats usually indicating the ICs have failed. Usually with that model its best to replace the board rather than try replacing the individual components as ther are several 3.9 ohm resistors that will need to be checked and possibly replaced along with both ICs. www.tvcircuitboards.com should have the replacement board for your model if you need one.

It should be a 4.7 OHM if its under the heatsink near the convergence chips.

You can do the repair yourself using the following instructions.

The actual Convergence amp ICs not located on the convergence board are probaly what killed the origional convergence module, and likewise has killed the new board. You will need to change the convergence ICs first then replace the convergence module.
I would recommend getting the service manual . I can post a link if you would like.

AUSTRALIAN PARTS


the convergence board has nothing to do with tuning of tv, the convergence board put three colour gun (red, green, blue) to work with each other, else you get three image, of red , green,  blue or mixture of all as seperate image, the convergence board for american tv and Australian tv is possibly the same what you check to see the board  part number is the same you possibly need to see if the convergence board has got the memory i.c. if that is the case, you need to tune you t.v reset the channel etc good luck.
need more help let me know.

Do NOT attempt to enter the service mode to align convergence if you cannot align the convergence with the user's menu. If the convergence cannot be corrected with the user's menu, it means that one of your convergence IC's has burned out and possibly burned out the fuse next to it. If you change any settings without first replacing the bad parts, you will only make things much worse. I believe that set is actually a Samsung, and has the 2 convergence IC's on their own board mounted above the small signal board. If you do not know how to identify and replace shorted convergence IC's, allow a qualified tech to handle it for you.
