Hitachi 43FDX15B 43" Rear Projection Television - Answered Questions & Fixed issues


I'm sorry for the difficulties you're experiencing in viewing the pictures in full screen. Please set the Aspect Ratio Settings on the TV to Aspect Ration 1 as shown in the below picture to resolve the issue.

This model uses two convergence IC's----if 3 D one or both are bad.


Most of the time this set uses either two of the STK-392-110 OR THE STK-392-150 CHIPS.

Both chips and any bad protection resistors around them need to be replaced and the set adjusted.

If you are able to do the repair yourself total parts cost will be under 30 dollars.

Some history for you:
This set like all rear projection tube type sets uses two chips---the ones in your set are Black in color--about 2 1/2 inches wide X 1 1/2 inches tall and are on either one large or two smaller heat sinks with fins on them.

When the chips are installed a white grease called heat sink compound is applied to the metal back of each---the grease transfers heat from the chip quickly to the metal it is bolted to.

After some years the grease dries out from the heat and one of the chips goes instantly.

You can buy a pair of the chips for your set on Ebay for less than 15 dollars plus shipping--

If you cannot do the repair yourself--shop around your area---most shops charge 300-400 for this type of repair. Whoever you get to do it make sure BOTH chips are replaced or you will have the same problem in a few months.

If you open the set and locate the chips---they will have the full STK number printed on them in white letters----there are about 12 resistors around them that need to be looked at--if any are discolored they need to be replaced.

If a shop says it HAS TO GO TO THE SHOP keep looking as any good tech can do this repair right in your home in about 1 hour---I know as I have done hundreds of them.

IF you can solder and are handy I will give you general instructions on how to do the repair and what you need---some people I talk to can either do it or have a friend who can do it for them---let me know

I can tell you what you will need aside from the parts and how to proceed with the fix---

If all this helped rate this solution---I do this here for free.

IF YOU HAVE ANY QUESTIONS OR NEED ADVICE LET ME KNOW--I am here to help people.

Regards, SD TECH

you may have a dead or bad color gun. go thorough the convergence routine and see if all the colors are there. If your missing a color, you can purchase just that gun but I would advice that your replace all three. Be aware that this can be costly and in some cases you may have to purchase the whole pc board with the three color guns on it, depends on the model.

In a nutshell, the convergence ICs have failed. The cost to fix by a service company is likely about $300. You may find someone who does it on the side for around $150.

If you are happy with the picture, you like the tv, then $150 might be worth it.

It is possible to do this repair yourself if you have an electronics background.

Please do us a favor and rate this solution after reading.

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.

A pop means that a component inside the tv has failed the big way - it has exploded. The red button that blinks is the status light - it signals that a massive short has been detected and the power source of the tv has been forcefully shut down. The clicking comes from the source, it keeps trying to start so the protection system keeps shutting it down.
The failed component will have to be identified, replaced and the rest of the tv tested to check what other damage has occurred and fix it. This is a job for a pro, no way you can fix that yourself. Unplug the tv from the wall - leaving it powered only makes the damage greater - and call one.

Hi,

When you turn it on, does the red light sort of pulsate on and off?
Do you hear any odd sounds (a squeal, perhaps, as the red light flashes) coming from inside the set?


How old the unit is?

Let me know,so that we could proceed.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Take the back off the set and resolder new cord into the circuit board that the old cord came out of

Hitachi 43FDX15B... | Answered on Sep 24, 2010 | 24 views


I think this set uses 2 of the STK-392-120 chips but it is easy to tell. They are as you look from back on far right side on large metal with fins--either -120 or -110 chips.

This can be a do it yourself repair (parts on EBAY cost under 25 dollars total)

See attached photos of what the board should look like, the chips are the black parts with 18 pins each.

Let me know if I can help, it is worth fixing if you or someone you know can do it.

It seems that you have a clear case of dry/ poor soldering joints on some sections of the main board. Remove the main board, disconnect the power and use a good lamp to investigate. Use a good soldering iron to TOUCH up all the poor soldering joints, could be series resistors, Ic's , outputs drives, inductors or even connectors. Take time and do NOT be hasty to be careless and bridge up circuits to damage your set. Hence if not confident get a friendly technician to help with this advice. I m sure it will be solved. Hope I could help. Good day

When u turn the tv on,u hear alot of clicking?That mean the Ballast that help the projection bulb to work is dead.Change the Ballast,might as well change the bulb too.U don't know what is the condition of the projection bulb in.

Hitachi 43FDX15B... | Answered on Dec 24, 2015 | 410 views


3 reasons for this.

1st reason the fluid is contaminated and thats why u dont get red.

2nd reason no red drive possibly due to a bad colour driver on the base of the tube neck.

3rd reason the tube is out.

If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

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 - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

93a1209.pngCONVERGENCE SOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com
