Iqc60h95w zenith=hitachi i can set up convergence but when i press swits on the main board to retorne the picture the convergence wont stay on memory.witch butons on the remote i have to press before press...


Projection TV2_bing.gif 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, Samsung2_bing.gif, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith2_bing.gif, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • Screen looks 3D2_bing.gif
  • 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 flash2_bing.gif 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

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

Tv turns t"s self off,take 20 minutes to get back on


Check the "sleep timer" function and make sure that it is not turned on (if it has one) - one other thing I would try is to be sure that an energy saving feature is not enabled that puts your TV on standby after a period of time (although this is unlikely).

Tv turns off by it self


Ours 60" (60P8342) turns off after a short period of time also. My husband researched it online. The cheap solution he was told to try is to unplug the TV (or plug into power strip and switch off) when you are done watching it. A computer board inside over heats and it's a protection mechanism for it to turn off. Otherwise, it's over $100 to fix the computer board.

Samsung Rear Projection TV - SP43H3HT


There is a problem with the self focus function on the TV set.  We have had ours replaced twice. Once under warranty and once out of pocket.  After you get it fixed, if you do, the self focus option needs to be set to "OFF" and only focus the TV when necessary.  Ours is going out again unfortunately. You would think paying what we all did for this paticular TV  we would or received a higher quality project.  However, Samsung only hymns and haws about it and offern absolutely no help other than TV repair people in our area that they know about. (which seem to charge absolute top price).

We tried to get the screen replaced while under warranty and were unable to Samsung wouldnt cover it.  Now we cant even locate the top layer screen and pay for it ourselves.

I dont think I will ever purchase a Samsung TV again.  Never again.

Mitsubishi wd-62327 red light


1. Self-diagnosis error 4-4, check for open F9A06 part # 283P128050 on the Power PCB. 2. Self-diagnosis error 4-4, check for proper seating of the DVI cable between the FMT PCB and the DMD (Light Engine). It may be necessary to disconnect and reconnect this cable to insure proper connection. 3. Self-diagnosis error 4-4, if F9A06 is good and the connection on the DVI cable between the FMT PCB and DMD are secure, suspect the Light Engine part # 939P977020 4. Self-diagnosis error 4-4, check F9A07 part # 283P128050 on the Power PCB, if open suspect the Light Engine part # 939P977020 5. Self-diagnosis error 4-1, suspect the Power PCB part # 930B929001
