Question about Hitachi 53UDX10B 53" Rear Projection Television

3 Answers

Convergence problem I have a Hitachi 53UWX10BA projection tv. I need to replace the convergence ICs. I plan to change them myself. I have STK392-110 units in my tv now. The tv has been repaired before for the same convergence problem. I found online to use STK392-120 convergence units. Which do I need to use? What is the difference between the two?

    I have the same problem, how to start looking for the IC?

    When the TV is ON, the top side doubled and converged. Can anybody tell me what's the problem?

    When point to the right direction, I can replace the components my self.!!

    Hitachi Model 53SWX10B with same problem. Will the same parts for 53UDX work and what is the parts link to order? One online parts reseller indicates a hybrid IC (STK394-16). What is your opinion about this? Thanks for the help.

Hello,
I have the same convergence problem with my Hitachi 53FDX20B. Blue ghost image appears. Do I have to replace STK392-120 Ics? If so how many are to be replaced? Is there any resistor that I have to replace? Where are they located. Please help. You may send your reply to me at shenoydiva@yahoo.com. Thanks again. Can you send a picture of the circuit board and circle it?

Yes,but the front that not what u wanted to be open.The back of the tv that what u wanted to be open.That where the tv convergence board is,that the board require reparing.Yes,if U have all the tools and can do basic soldering works too like take out desoldering ICS take it out of a circuit board and resoldering ICS on put in onto a circuit board and also desoldering/resodering like take out small components parts and replace with new small components parts onto a circuit board?Yes?The tv convergence board must require replaces like 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board to solved the tv convergence pictures problems.Tries websites like Tvrpairworld.com,Tvrepairkits.com to buy a whole complete convegence kit belong to ur tv make and model the kit also will have a dvd disc of tutoring job too.Or tries tvs shops will cost u like $300-350 for parts and labors.

Ur tv have a problems known as a convergence problems,it dead.Tv have corlors R,G,B lines mis alignments,have colors shadows picture or 3D picture look alike?Yes.The tv convergence board is dead.The convergence board must change 2 STK convergence ICS and some or all of it resistors to fix the convergence board to solved the tv convergence picture problems.The shop will cost u like $300-350 for parts and labors.

Hitachi projection tv 53uwx10ba - the Convergence ICs were replaced. When the PDKP bridge between convergence board and 2nd board is plugged in, it makes a noise. Kept that unplugged, the picture is...


Did set have this problem before you replaced the STKS?

I know these sets very well. If problem is different in any way from before you replaced chips.......double check all soldering or one of the new chips may be defective.

The more you tell me the better I can help.

Hitachi 53uwx10ba turns on & off when off red flashing light/clic


Same problem. Replaced both convergence ICs about 5 months ago. Worked fince since then and just recently no sound, no video, blinking red on front panel and clicking sound. I suspect that the ICs went bad again and blew a resistor or two. I used cheap Chinese ICs instead of the Sanyo ones and thing this is why. I'll be looking at it again and post solution.

Replace the conv ICs. Sometimes it's just the soldering involved, DK on Hit. But bottom line it's usually the conv ICs. They work very hard in there.

I would change both ICs STK392-110 and also the 3.3ohm 1 watt resistors and the 1.8 ohm 1 watt you would need 2 of each resistor. Then your convergence would be new again. You can get replacement ICs and resistors at the following link with free shipping and free instalation instructions with pictures.

Double shadow green and pourple


check the 3.3ohm resistors right next to the convergence ICs. Also the ICs for 3.49 are most likely cheap chinese ICs and not origional sanyo ICs . I have seen the cheap ICs go out as soon as you power up the set the first time.If you need more assistance please let me know.
