but he damaged,, the little Circuit board, that plugs into the Back of the YOKE... one heat sink was bent,, and damaged some of the board....
I can see some cracks.. and the coppertraces are broken.. in some places..

No instrution sheet that I know of. Those "F" connectors are most of the time part of the "tuner", if so just take off the tuner (unsolder it) and pop off the two sides of the "tuner can" and straighten the "can". Take the "F" connector with a small screw driver and scrape the side of the connector to make it shinny and so the solder will stick to it, and do the same to the "tuner can". Use a good hot iron to solder it back on. Do NOT get the "F" connector so hot that the inside of the connector will melt. The center conductor of the "F" connector will have to be soldered back into its hole as well.

You can repair any of the traces with small wires from the affected pin to the next componnent on that trace. To remove the board label all wires that you disconnect. There are "bridge" connectors that connect the signal bd and main bd. these lift up off the main board and will stay attached to the board youre working on. If you need further info please let me know. Also use solder wick to remove the solder and get a small tip solder iron 30watt from radio shack. The proper way to solder is (1) allow the iron to heat up. (2) touch the hot tip to the pin on one side and then briefly touch the solder to the other side of that pin so the solder flows around the pin. Use the solder sparingly so you dont bridge the pins with solder. (3) always check your work with a magnifying glass to insure the pins arent bridged.

dear friend if you have that type of skills you cerlainly can either resolder or replace the convergence stks. you we'll need to replace both if that's the case. they look like the audio outputs in the audio amplifiers. good luck

Well, my thought is that there are a ton of knock off generic convergence IC's out there that usually hold up as long as yours did. Professionals like me will only use Sanyo original STK's. The counterfeit STK's out there are everywhere. Do some research on the web to locate Sanyo originals, they are out there.

That's your HV distribution block, lift up the rubber boots and hold the block down and pull the red anode leads out, one at a time.
