Question about Hitachi Projection Televisions

Open Question

I have a Hitachi 32LD8600 LCD tv and the sound has started to have a kind of razzling noise and when it does that the normal sound disappears. It is ok for a while after I turn the tv off and back on again.

I have seen similar problems (features?) with Syntax LCD TVs. One thing to try is to make sure that the backlight brightness is set to its highest setting. On my Syntax, when this is set to a darker setting, it produces annoying hum through the speakers. Mine also is smart about turning *off* the audio amplifier when set to zero (or mute), which sounds like the behavior you are describing.

How can i fix my hitachi ultravision it has green and double vision on top of screen


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

54inch Hitachi TV has double figures and colors red, yellow-not normal. Set approximately seven -eight years old. Lost remote control and direction book in moving. Is the set worth getting fixed? Generally...


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 Sony2_bing.gif,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer2_bing.gif, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

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

Problem #1) Convergence

Yours may have one or more of the following symptoms

  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a 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

Sound shuts off. TV model 61SWX12B


If this set was made around 2000 it may be the audio module that is no longer available---They had all kinds of troubles---if your set has this board (looking from the back of the set with the cover removed--unplug set first) it will be mounted above the main boards on the left wall of the cabinet---it is about 5 x 6 inches in size.

Basically the problem with these was they crammed a lot of stuff that gets hot on the board and solder problems develop---

You find this board you really only have a few choices--You can have the board removed and sent to a company called PTS ELECTRONICS WHO will repair/rebuild the board for you--You can find them on the internet.

This board has several plugs and only 2 or 3 screws hold it and the metal frame for it to the inside of the set----Hitachi had detailed instructions for this repair on their technical site---I along with several other techs who looked at this decided considering the amount of time to try to fix it---it was cheaper just to send it out for rebuild---PTS should have a 800 number and can give you a quote for this service.

Let me know if you have ANY questions or need advice. Any good TV tech who actually looks at this set will be familiar with the problem---The first one I saw was a brand new one with no sound from right speakers, right outs etc.

REGARDS, SD TECH
