Question about Hitachi 43UWX10B 43" Rear Projection Television

2 Answers

Convergence IC's? I suspect my Hit. 43UWX10b (5 yrs old)  requires new Convergence IC's as the several colors are bleeding down and to the left. How many convergence IC's does this model require if I were to replace them all? I got a price of about $40 US each from Sears.

Re: Convergence IC's?

If one or more B+ resistors have changed in value,the life of

the new IC is reduced.Compare resistors in one circuit with

match in other IC circuit.

Note: IC's can be generic cheap or name brand more expensive.

My set is 10 yrs old. In the upper left and lower

Try adjusting the convergence. If it won't move see below- red IC in particular
This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!

If the picture was good prior to the 3D images, I would fix it. The convergence ICs either have poor connections or are defective. The IC is an STK392-110. There may be 2 inside the set. If you have this repaired, expect a labor cost in the $200 range. Request that the ICs be replaced rather than the board changed. This will maintain all of the internal settings and require only part replacement not a complete re-convergence adjustment.

Keep us posted.

Hitachi Convergence

Check out the Convergence Gallery. If you see the colored outlines or color shading as in the Gallery, you have a convergence problem.

The repair for a Hitachi requires the replacement of the defective IC or ICs and any damaged or smoked resistors. Some models don't have a separate convergence board and the board is not usually available for the ones that do have a separate convergence board. Usually there is little alignment required after the repair. If you play with all the adjustments before the fix, hours may be spent re-aligning.

If you change the original ICs with substitute "new and improved" parts that are talked about in the blogs, you will probably create problems. Use the original ICs and resistors.

Don't monkey with it.

This is a delicate and difficult repair. If not done by someone with some electronic repair experience, the TV will likely end up as junk or cost considerably more for a tech to fix the damage done.

If you live in Calgary, call me. If elsewhere, find a competent tech.

Good Day,

Sounds like the TV's convergence circuit has failed:
*Call an Authorized Service Center and them give you an estimate cost of the repair, or
*Repair it your self; get KIT 10 locally or B&D Enterprises
Good luck, big IRISH.

43UWX10B problem with green

if you have a 2 IC convergence chassis they dont control the green , However if you have the 3 IC chassis the green is controlleed by the third IC these are usually STK4275 or simallar single amp ICs. Which type chassis does your hitachi have? Its possibly related to the digital convergence board if all resistor near the ICs are good. Do you have the service manual? I can post a link where you can get the full service manual if you need one

Covergence and Bowed Picture Problem

can you adjust any color of convergence in user menu blue, or red up or down left or right. if you can make any up or down left or right adjustments on any color then the likelihood it wont be a convergence ic. it would be a output resistor. so see if you can get any movement. with it being bowed i was suspect an convergence ic.
