Convergence problems


Did you buy the board new or used? It could also be your convergence Ics and not the convergence that is causing the shutdown . The convergence ICs are not located on the convergence Board.

One of your convergence output IC's has stopped working and needs to be replaced. This is a very common problem in projection TV's. The IC should be replaced and the convergence circuits realigned by someone with experience in repairing projection TV's.

My 54" PCN5425R TV will not turn on


You will need to locate the convergence amp IC's, the STK392-040, and replace both of them. The originals IC's can be ordered here http://www.mcminone.com/search.asp?keyword=STK392-040&btnSubmit.x=4&btnSubmit.y=6 Good Luck

Another Question Please.


Horizontal lines can be cause by many things. One of which is the convergence module. $130.00 is a little high for something that can be caused by other things as well.

Disconnect the convergence board and see if the set comes back on. If it does, replace the convergence board or the STK392-040 Convergence Amp IC's. Good Luck
