Question about Hitachi 51G500 51" Rear Projection HDTV-Ready Television

Hitachi 51G500 picture scrambled

I was having a convergence problem where the red was out. I replaced the convergence unit and now everything come up scrambled. Any reason?? What did I miss? I also checked the resistors in the convergence circuit. All but one tested fine. The odd one tested good but wasnt matched to what the schematics called for. It was the RK42 which tested at 19ohm and was marked the same.The scematics called for a 3.3 ohm so I replaced it. Still have the scrambling issue though.

    All the parts I used were ordered from a site online that caries hitachi parts. I used the part numbers from the service manual and cross checked them with the existing parts where applicable.

    Same as b4 only I also have now replaced both convergence IC's Which i know wont help the scrambling issue but hopefully now the convergence will be fixed. Any help would be greatly appreciated!

    thanx

    Hmmm.. I ran the cable for my internet connection over to the tv (cable internet)and whalaa!! a picture. But still comes up scrambled on the s-video input from my stereo reciever. It was fine when I initially brought the tv home a few weeks ago. Could it be some form of copy protection? Although I dont see why it would be doing it now all of a sudden. Will try a simple solution of using a different cable I guess. Weeee..this is fun!

    Ha! It WAS the cable!Now for the finishing touches on the convergence.

    ok, Dissectional, please rate me thanks for trying so that your problems visible to other expert.



    In this case i suggest you to bring your TV to the service center so that all the parts will be clearly diagnosed for errors because some part of it indicated no sign of error. that errors cannot be detect by an ordinary tester.



    best regards, melnavz

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
