Hitachi 61SWX12B 61" Rear Projection Television Questions & Answers
Convergence problem
Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com
Common Problem #1) Convergence has gone out
Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.
Common Symptoms include....
- 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.
- TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy
Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

How do i re aline my projection Hitachi TV out of
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
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.

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)

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
Sound problems
you have defective speakers! you can repair your speaker change the spider suspension wire! thats why your speaker is crackle sounds!
Change input on Hitachi LCD TV model LE65K6R9 without remote?
I'd unplug/disconnect the Roku and after 30 seconds try the control button on the back. If you can change the input do so, then plug the Roku back in. Until you use the input button on the back to change input to Roku, you should be able to use the other buttons on the back to control the TV. If this does not work, unplug both the TV and the Roku. Wait maybe a minute, then plug the TV back in and follow the above instructions. Here are other alternatives: Using physical buttons: You can find the physical buttons on the left or right back side of the Hitachi TV. Using these keys, you can change the input, adjust the volume, or turn on Hitachi TV without a remote. Press the Input button located at the back or side of the Hitachi TV. The list of connected sources will appear on the TV screen12.
Using external devices: Connect a wireless keyboard or mouse to your Hitachi TV and change the input1.
Buy a universal remote: You can buy a universal remote to control your Hitachi TV and change the source.

How to remove small popup bottom left of Hitachi smart tv screen.
A little popup that appears in the lower left corner of your Hitachi smart TV screen may be related to one of the TV's settings or capabilities. You can attempt the following actions to get rid of it:
1.Investigate notifications:
Smart TVs occasionally show notifications for different events or upgrades. If there are any notifications, look for them and then clear them by following the on-screen directions.
2.Applications and Inputs:
Make sure all programmes and inputs are closed. The popup may occasionally be connected to an input source or app, which can be closed to get rid of it.
3.On-Screen Display (OSD) Off:
There might be an OSD option in the settings menu on Hitachi TVs. Try disabling OSD or changing its settings to see if it gets rid of the popup.
Verify any software/firmware updates:
4.Make that the most recent firmware or software upgrades are installed on your TV. Pop-up windows may appear as a result of faults in outdated software. Look for a software update option in the TV's settings menu.
5.Firmware Reset:
You can conduct a factory reset on your TV if the problem persists after you've tried various troubleshooting measures. The default values for all settings will be restored as a result. Make cautious to back up any crucial data before doing a factory reset because doing so will also remove any customised settings and data.
6.Message Hitachi Support here:
If none of the aforementioned fixes the problem, it's a good idea to get in touch with Hitachi customer service or refer to the TV's user manual for detailed instructions on how to get rid of the popup.
Regarding External Devices:
7.The popup may be related to any external devices you have connected to your TV, like a cable box or game console. Make sure that these gadgets are operating properly and that the settings have been changed as necessary.
Keep in mind that depending on the type and software version of your Hitachi smart TV, the precise processes and options may change. For instructions unique to your TV model, consult the user manual, or go to the Hitachi website for further help options.

Hitachi LE42S704 none of the HDMI ports work, need to update (i think)
Are you getting the various HDMI inputs on the screen but it acts like nothing is connected? We have repaired hundreds of TV's with no HDMI signal over the years and have never had an update correct this issue. There is an IC close to the HDMI input jacks (U501) that decodes the data, that's always been the defective part. You can order the part and change it but you will need advanced soldering skills and the equipment to do it, I'd recommend replacing the main board if you can find one.
