Question about Hitachi FDX Series 43FDX10B 43" Rear Projection Television

2 Answers

Picture Too Large for Screen

The picture appears to be too big for the screen. TV station logos, names, etc. are chopped off.

Had the convergence feature repaired and since then have had this problem. I could not find a fix in the manual and was unable to find the problem while looking through the setup menu.

Please advise. Thank you

What you described sounds like a convergence problem. When convergence has failed the colors will commonly look 3D,warped, etc. This tips page here on Fixya has more details.

Picture is wiggly at top. this does NOT happen when watching hi-def stations.


Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. 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,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

THE PICTURE IS GHOSTING AT THE TOP & BOTTOM OF THE SCREEN. THERE


The most likely cause is shorted convergence chips and possibly a few pico fuses.

DOUBLE IMAGE ON SCREEN. tOP OF PICTURE LOOK LIKE A


That symptoms are due to failure of convergence out ICs in your TV that will be replaced to get correct converge picture on front screen.

There are 2 big black IC mounted on big aluminum heat sink and number would be written on as STKxxx, these 2 ICs will be replaced.

If you want to repair TV by yourself then confirm model number of TV to provide you more info or call local tech to replace said ICs.
Thanks.

There is a picture but it is blurry with a big yellow blur.


Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

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.

f0900cb.jpg
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.

2c07611.pngSolution #1

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.


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.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

The picture is distorted. It appears as the picture is being drawn to the center of the screen.


This is a convergence problem. This can be either bad solder connections at the convergence ICs or defective ICs. If you can solder, you can fix this yourself. Try resoldering the pins on the convergence ICs. If that fails, replace the ICs. These are large black ICs attached to a heatsink.These should be marked STKxxx.

Keep me posted.

Projected image is too large for screen


Good Day Brian;

The warped, too large picture is the same problem, the TV has a convergence problem. ln today's electronics the first thing that should be done on any electronic device is to, reset, unplug TV from the a/c outlet for at least 4-5 minutes then plug back in. If no fix; Your TV has a circuit problem. RCA has three common problems that could cause this condition; the most common is a fuse near the fly-back, IH-VT, the convergence power board or the signal board.

Always, call a factory authorized service dealer if you are not familiar with repairing electronic equipment that contain HIGH VOLTAGE, just for your own safety.

Good Luck, Big Irish.
