Question about Hitachi 61SWX12B 61" Rear Projection Television

2 Answers

Convergence problems? I was given a Hitachi 61SWX12B. The internal sound doesn't work. I haven't really started looking at that problem yet. I'm trying to get the video to look good first. Here is a link to a photo of what the screen looks like in service mode. What is the best way to fix this problem? I tried to line up the grids using the remote but the red starts to really screw up. I start getting lots of red lines going crazy. Any Ideals on what I can do? Thanks

Re: convergence problems?

While the OP may no longer have this issue, I'll comment on anyone else that may come across this.
In addition to the suggestion of replacing the ICs above by Leadtech, the resistors also should be changed at the same time.  Quite often, even if a single IC or both are replaced and the resistors are not, the issue will re-appear.  There are a few locations selling a kit in the $50 range, so the difference for the additional resistors is minimal.
As for the sound issues, several owners of this and other Hitachi RPTVs in this line have had issues with their sound boards, which seem to be largely a defective product.  Even replacement of these have resulted in the problem re-occurring at a later time.  I would suggest using an external receiver and speakers as it may not be worth the time and money to repair this problem.  -TD

Re: convergence problems?

Replace the convergence ICs. In this set the power resistors in the convergence circuit tend to change value, if not burn up. An alignment afterwards would be next. The audio may be as simple as the speakers turned off. The first thing to check would be the voltages to the output IC. If audio comes out of the audio out on the back of the set, you may use an amplifier for sound. Good Luck

How do i re aline my projection Hitachi TV out of the 6 x 5 are out of line how do I fix it

I'm not sure what you mean by: "out of the 6 x 5 are out of line"
If you are referring to aligning the colors on the screen, the settings you are looking for are called "Convergence". There will usually be a red, blue, and green cross you will have to line up perfectly. the green is usually not moveable.

Looks like I have extra blue and yellow lines abow the image on my Hitachi 61SWX12B 61 in , just started today ?

If you go into the customer menu and select convergence and red or blue are skewed and will not adjust---you have a convergence circuit problem.

61SWX12B uses two of the STK-392-110 convergence IC chips. Both chips and any bad protect resistors around them need to be replaced and the set adjusted with the Hitachi remote.

Most of the time just both chips need to be replaced and the set adjusted.

Considering you can buy all the parts needed for under 30 dollars on Ebay if you or someone you know can do this repair you can save a lot of money--most shops are going to get 300 or more. I can give you general instructions and tell you the best seller to get the chips from on Ebay---I buy the ones I use there.

I have no sound on my hitachi 61swx12b

Try these items first: re-set TV and any type of BOX you have hooked to the TV. 2) Ensure all cables are secure. 3) Make sure that there is not a speaker switch on back of TV. 4) go into customer menu (audio) and make that speakers are turned on. 5)
Cause: Remove ALL jumpers on bottom of SRS pwb.Add 1000mf@16v across CSH1 add 1000mf@16 across CSH4 add gnd wire 24ga from PSU1 conn pin 18 to IT02 pin 97.

Good Luck, Big Irish.

Hitachi projection hdtv has 3d effect and bowed shape

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

Check what is happening when you press flash focus?It completes 1 full cycle or not?
If not complete 1 full cycle check small value resistors on convergence board.All RK series resisitors..

I believe you can order the convergence board replacement for $299 from Part Store, here's a link to it for my 61" Hitachi, which should use the same board:

They offer a 30 day hassle-free return policy, so if for some reason it wouldn't work for you or isn't the right part, all you'd be out is the return shipping, as the initial shipping is free.
I'm in the process of having my board fixed w/the IC/resistor kit and hopefully I don't need a whole new board.  We'll see, but give this a shot, I don't see how you can lose...  -TD

Both of these problems sound like the 2 convergence ic's. Not something the owner is really able to repair. You'll need to call a svc co.
