I've Panasonic TV TX51P100H with convergence problem, A group of tech try to fix this TV because in service mode lines are bent to inside (up and bottom, left and right) and line data didn't moves with cursor.We replaced both STK IC two time.

SOURCE: convergence problem
That unit has a convergence repair kit that should fix most problems. Order it directly from Hitachi p/n# X480295. It contains: Rk42 3.3 Ohm 1w Rk46 1.8 Ohm 1w Rk50 3.3 Ohm 1w Rk54 1.8 Ohm 1w Rk58 3.9 Ohm 1w Rk62 2.2 Ohm 1w Ik04 Stk392-150 Ik05 Stk392-150 And I would strongly recommend testing all the resistors in that circuit for change in value. Are you using a good heat sink compound on the STK's when you installed them? That and ordering the japanese knock-offs for STK's are the two most common critical mistakes made. Originally that unit had two STK392-110's for conv. amps. Even Hitachi recommends subbing to a STK392-150 or 180 for greater reliability. You do realize that for the cost you have after two failed attempts you probably could have taken this to a reputable shop and watching the ball games now. :) (no disrespect intended) Good Luck! Bill

the pico fuses will usually need replacement when the Ics go out they take out the two 5amp pico fuses.You can get replacement picos at the following link.

No. If you already tried, you already know why. Repair on TVs require the exact parts. If you feel you can repair this, the suggestion is see the website,www.TvRepairKits.com. Here they can instruct very throughly. You will find photos to see what you will be working on. I have repaired several TVs using this web. Be sure you have the model number and the symptoms you describe. If you have any further questions concerning repair, ask me here. Thanks for asking and show a few hands of support.
