Question about Hitachi 43FDX01B TV

1 Answer

Hitachi Tube TV, 1994, 31", model 31DXT1B. Problem is the top third of the screen is distorted in that it will take the top third of the image and wrap it over itself (horizontally). The distortion height at the top of the screen seems to vary from time to time, from 25% to 40%. At first it would happen and then not happen. Now it happens all the time distorting 25% to 40% of the top of the screen. This happpens on all inputs (RCA, Coax, S-video). Thoughts?

    There are approximately 100 capacitors. I would need to identify the "Vertical Deflection section" to remove and replace those capacitors. Can I post or email pictures of the circuit boards of the TV to identify the "Vertical Deflection section"?

Hi,
This kind of problem occurred in TV when one or more electrolytic capacitors in Vertical Deflection section becomes dry/ leaky.
Please replace all electrolytic capacitors in vertical out section in TV, these would be around 6 or 7 capacitors and TV picture will be fine.

If you are handy with electronics stuff repair and can solder parts in circuit board then do it yourself OR contact local TV tech to do the job.

Thanks.

Hitachi C21 model.The colours on screen have got scrambled.


It sounds like something has left a strong magnetic field on the face of the picture tube, and that's causing the colour distortion. The electron beams from the tube's colour guns are hitting the wrong spots on the face. There is a degaussing circuit in the TV that tries to neutralise such fields every time the set turns on. Sometimes electrical equipment (particularly motorised appliances like a vacuum sweeper) operating too close to the TV can leave a field too strong for the degaussing circuit to cope with. Or a failed part in the circuit may have made it inoperative.

A hand-held degaussing coil can be used to remove the field. You can purchase one online, or call a TV service technician. It used to be a standard tool to carry.

Another possibility is that the tube has been damaged. There is a very thin metal mesh screen called the shadow mask behind the face of the tube. If this mask has been warped by a strong magnetic field or a mechanical shock (if the set was dropped, for instance), you will see the same colour distortion. In this case, however, there is no repair other than tube replacement. And that is likely to cost more than a new set with parts and labour.

Hitachi 43FDX15B distorted picture. The top of screen displays a half circle cirle and the image is distorted within the half circle. The same at the bottom of the screen. The middle of the screen is fine....


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.

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

Hitachi C50-FD2000 Screen Distorted


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. To get fixed either call in a local TV repair company or goto sites such as Tv Repair Kits to get a repair kit with instructions. Here is there link.
