Hi my name is Greyson, i have a hitachi big screen and have just had the convergence ic's replaced, i also replaced two resistors that were supposedly bad...however the resistors were piggybacked together b/c i did not have the proper rating...the tv worked fine after the repair except for a red ghost on the left side. I thought it might be due to the resistors so i replaced them with the correct rating and now the tv goes into protection mode when turned on - two green led's flash. Any thoughts? Thank you

Hi, This tv has two big black ICs as convergence output on deflection circuit board that are defective and causing problem in tv, IC number is STK392-110 replace both ICs to solve tv problem, also chekc for faded color big resistor nearby these ICs or those got burn mark, replace these resistors with same value, aslo check cold/ dry solder joints in deflection circuit board and resolder these joint/ connections. Thanks.
Ur convergence is dead.Must know how to solders?Tries Tv repair World.com,Tvrepairkits.com to buy convergence kit.Replaced ICS and all it resistors to fix this problems.The shop will cost u $300 for parts and labors.
The 392-150 is a higher current device then the 110---you can use either--this is normal in the hitachi sets---I usually replace both with 150's---check the led that does not light---should indicate which voltage source is bad---if it is one of the 2 voltages for the convergence ic's(one is a positive and the other a negative voltage) then the convergence Ic's may be bad---look for any discolored resistors around the ic's---one way to tell if it is a convergence ic is to de-solder both ic's and see if the set turns on(the convergence will be out the window) but if it comes on change both and do the alignments with the Hitachi remote. By the way----the led should have a location number printed on the top of the circuit board.
Replace Both of your convergence ICs they are big black ICs and ck resistors RK4246,50,54,58,62 i have the values if you need them they are 1.5ohms up to 3.9ohms.ICs will have STK392-110s if this is the number on yours upgrade to 180s
Replace Both of your STK ICs they are your convergence ics they are big black ICs will have Part# on them for example STK392-110, if they are 110s use 180s, if 020s use 040s other wise replace with exact same number. To get Parts call Electronix 1-800-223-3205
Dave, HMMMM Dual pictures This is a problem that every projection TV runs into at least once or twice in its lifetime. Its the old convergence IC falure thingy. These IC's go bad and should be replace all at once. These are not consumer replaceable unless you have had training in the electronics or TV repair fields. Please call out a pro to assist you with this repair as A TV is not the place to experiment in because of the HI voltage and saftey issues. Good Luck
