Question about Hitachi 53UWX10B 53" Rear Projection Television

1 Answer

Any assistance appreciated

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

    I tried the menu convergence but the red would only go so far...it was still bowed in on the left side, should I check solder on the ic's as well? Thanks

  • Greyson Feb 03, 2008

    does it matter what % my resistors are? I used 5% because thats all the store had...thanks

  • Greyson Feb 04, 2008

    ya i got the newer ones from hitachi

  • Greyson Feb 04, 2008

    sorry the ic's are stk392-110...do they require different resistors?

  • Greyson Feb 04, 2008

    The ic's are the same number as in the service manual replacement parts list. I put 3.3k ohm and 1.8k ohm resistors in by accident first, then replaced with 3.3 ohm and 1.8 ohm....(correct) i just don't understand why it won't even turn on now....if ic's go bad won't the focus just be out and the tv should still turn on?

Check your soldering make sure you don't have any bad solder joints.
the red ghost on the left side sounds like you could have adjusted that out with the menu convergence.

    check the resisters and solder.

    no that should not make a difference. did you purchase cheap ic's?
    some have been know to be generic have been bad, did you purchase them from a good company?

    are they the same as what was first inside them? did you replace the resisters after you had turn the tv on and had installed the stk's?
    if you found the resister later then chances are you caused the new ic chips to go bad.

    btw you can purchase the same ic's from mcm electronics at half the cost.

    with that high of resistance you would be correct.
    make sure your connectors are in all the way and nothing is bent or out of place. there might be fuses that are the size and look like resisters around the H.O.T. thats about all i can think of.

On the screen there is a green shadow on one side and a red shadow on the other side of every object in the scene


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.

Hitachi 51UWX20B no sound, no picture, blinking green LED


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 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

Picture has a blue shadow


Hi,
Seems convergence out IC is fried in TV so it gives blue shadow.

Check out Convergence Out IC which you need to replace in TV, if you have enough experience of repair of big TV, necessary tools and know basic electronics.

Red Lines on Screen


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
