Question about Hitachi Televison & Video

1 Answer

Ok here we go..... i have the hitachi 61udx10b and i have had the convergence chips replaced last month and the tv was fine, two weeks after the it started turning its self off... called the tv guy again, he came back and had to re soder 7 of the 11 connections associated with the horizontal on the circuit board and he also replaced a transformer (BM00634)when he turned on the TV the picture was bowed on the upper left hand and right hand corners and short at the bottom...so he did an adjustment to the horizontal with a knob inside the tv and it helped to a point, but he said he needed to do some research and come back, well in the mean time the set was watchable so i watched it and the picture eventually evened out at the bottom and top, so when the tv guy came back all he did was readjust the convergence and horizontal and it was ok for a few days... tonight after being on for 5 hours or so, the picture once again started to flicker and the red and blue bow up from the bottom into the middle of the screen.... can any one tell me what the hell is going on with this thing, because the TV guy seems to be stumped and so far i have put closet to $500 into it....is this set fixable or and i wasting my time and cash?!?! please email me at dls031568@aol.com THANK YOU!!

Replaced conv. chips stk150. It turns on now but red overshadows other colors and focus magic doesn't work


Where there burned or faulty resistors in the convergence output section that you did not replace? Did you plug the convergence yoke connectors back into the right places? Did you not do very good soldering and/or leave solder bridges or damage traces? Does you tv actually have a bad DCU? Did you buy generic convergence I.C.s? Alot of STK392-150's are poor quality generic amps. You should have paid more than $15.00 dollars apiece wholesale for them.... Oh and Hitachi also says the correct sub is STK3394-160E .. 150s should function though and are the old subsitute..Alot of poeple say use 150s but that is usually because they are cheap , don't care if it lasts more than 10 months and can't understand the problems with generic amps nor tell the difference.. Or you tv just needs some convergence alignment.

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

The red on the digital array will not line up.


Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

Stk394-160 Convergence IC, number on top right of chip


I have read both of the above posts.
On the first post, the 'codes' are the date codes. Both parts were manufactured in 2007, and will have no bearing on performance, should both lots not be the same as they were manufactured on different weeks.

On the second post:
There is allot of misinformation on the web pertaining to the applications of STK394-160(E)'s.
This special device was manufactured by Sanyo exclusively for Hitachi PTV's. They will not work in any other projection TV's except for Hitachi. Let me say this again, "They will not work in any other projection TV's except for Hitachi." The 'E' suffix is the nomenclature for PB Free or lead free. All STK394-160's were manufactured as 'lead free'. The 'E' will not appear on the part. Here's more information:

For Hitachi PTV's ( Projection TV's ), STK392-150 replaces STK392-110. STK392-120 should be replaced with STK392-120 or STK394-160's in matched pairs. The -120's are 4 amp devices while both the -110's and -150's are 3 amp. We market replacement kits for -110's that contain two original Sanyo STK392-150's and the associated resistors along with solder and resistor designations for all models. We also have an STK394-160 Kit, along with solder and resistor designations for all models.

Prelco electronics is a direct purchaser of STK's IC's directly from Sanyo Semiconductor Distribution. If you would like the real parts, your search has ended. Parts can be ordered on line, or toll free: 888-773-5268, ( 908-429-9999 local ) Sales X 2, http://www.prelcoparts.com

Hitachi 61UDX10B


I would check for burnt resistors as the 150s are interchangeable with the 110s however in alot of hitachis I have seen resistors blow after upgradeing to the higher wattage ICs. I Usually switch out the convergence resistors whenever I go to a higher wattage IC just to be sure. If you need more help let me know.
