Convergence issue... I tried to manually fix it through the menu option without any luck. The convergence does curve at the top and bottom of the screen.


It seems the solder is broken in Vertical Convergence Amplifiers or it is damage internally. This model has 2 Conv. Amps: 1 for Horizontal (Red, Green and Blue) and 1 for Vertical Convergence output (Red, Green and Blue), if the convergence does curve at the top and bottom, it is because Vertical Converegence output is no good. The Conv. Amp. costs around 20 dlls. Thats why you can not fix it with the Menu option. Good luck!

I have a blue shadow that outlines every image. the convergence of the blue cross does not seem to line up with the red cross as the manuel indicates it should. Also power has started to click off and on...


The problem is in the convergence system which can also cause the tv to not power up or intermittently turn on and off. About 50% of them are bad connections on the convergence power pacs. The convergence power pacs are easily located by the large heat syncs associated with them. The digital control board is located very close to the power pacs. Remove the circuit board housing the heat syncs and using high magnification look for rings around the pins of the convergence power pacs on the foil side of the board. Re-soldering up all the cracked solder joints in the convergence system including the digital control board should solve the problem.

If there are no cracked solder joints in the convergence system, or if repairing the connections does not restore the unit, the power pacs will have to be replaced. Ensure that you apply heat sync compound on the backs of power pacs or they won't last.

After replacing the power pacs, check all of the precision resistors for burn marks or detolerancing and replace as necessary. Next, although rare check the fuse links to the power pacs. This should complete the repair process unless there is some other atypical problem which is beyond the scope of this discussion.

If they tested the convergence board and thats ok, the only other Items it could be are the Digital convergence unit or the Velocity comando units that control the convergence yokes. If the convergence isnt adjustable with magic focus adjustments wont help it. Is the repair shop an authorized samsung repair facility? If you need more assistance let me know.

Blue color lamp cannot converge


GO TO THE CONVERGENCE MENU (MENU 2 3 5 9) AND CHECK THE ADJUSTMENT SETTINGS FOR CONVERGENCE. IF ALL ITEMS ARE SET AT "127". THE EEPROM SETTINGS ARE AT DEFAULT.

This website:

http://www.techlore.com/forum/thread/18547/Mitsubishi-convergence-IC-s-used-in-the-differant-models/

says your model uses the STK393-110 convergence chip. Another site I looked at said that was a 6 channel amplifier so I'm guessing you only need one to repair your TV.

If you do some google searches on "stk392-110 convergence problem" you'll find some good sites that discuss how to repair the tv. The STK392-110 is a convergence amplifier that is used any many other sets.

Good luck.
