Wavy green lines and offset during convergence calibration


There is whats called a convergence IC that is going bad inside this TV set. There is only one for all three tubes and the IC number is STK 393-11- and can be purchased here http://www.electronic-repair-kits.com/STK393-110.html You will only need to order one. If you are handy and can solder this should correct your problem. One very important thing is, before you reinstall the new convergence IC, make sure you use a good coating of heat sink compound on the back of the new IC. If you do not, the IC will fail within a short time frames. Only if you are good with a soldering gun should you attempt the repair. If you are not, this repair should run you about 300 bucks or so. Also if you are handy, there are seven capacitors that go bad inside a board called the DM board. These will go bad very soon so while your in there these should be changed as well. If you need info on how to change these capacitors, let me know and leave an e-mail and I will send you the pictorial on how this is done. the IC change you will need to find that, but I do have a service manual if you need one also to help you along if you can follow the schematic. Good Luck

How do i fix my toshiba flat screen 57" tv when it looks like it is 3d


Howdy;
It sounds like the convergence IC's have failed.
Replace the defective Convergence Output IC Part Number 23905094 (STK392-110) using the revised “T” version IC Part Number 23135090 (STK392-110T). When Convergence Output failure is detected, it’s recommended that both IC’s be changed to the “T” type IC version. Inspect the Convergence Output IC’s for the “T” type version.

The only items on your set that should need replacement would be both convergence IC IC801 and IC802 which are both STK392-570 and you will also need to change the two 5 Amp pico fuses which are F9A04 and F9A05 they are both % amp pico fuses. All parts are located on the center Board

Tosiba TZ55V61 Convergence IC 150?s vs 110?s


STK392-150 can be replacement for 110's no other resister values need to be changed, however be sure bad resisters are replaced and check all the resisters (6) have been taken out of circuit and checked. also check for solder cracks and cold solder joints.
