Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

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.

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.

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.

If by not fucuse, you mean that it appears like a 3D picture, then the problem is in the convergence circuit. If you can solder, you can fix this yourself. Please confirm the model number and let me know if you wish to attempt this repair and I will provide additional details and instructions.

Jvc av65wp55 out of focus


When you say you changed the focus block, did you adjust each color individually ? Most projection sets are adjusted by covering 2 lens and focusing each one seperately. Try this , it has always worked for me

Too much yellow does not adjust with normal drop screen adjustments. can i adjust the light beams.on my philips 50"

Turn the green screen control on the Focus Block until retrace lines appear and gradually turn it back
Until the point where you can see the retrace line disappears, just before cutoff.
2. Turn the red screen control on the Focus Block until retrace lines appear and gradually turn it back
Until the point where you can see the retrace line disappears, just before cutoff.
3. Turn the blue screen control on the Focus Block until retrace lines appear and gradually turn it back
until the point where you can see the retrace line disappears, just before cutoff.
4. If the screen still appears too bright after proper G-2 adjustment, you need to adjust the sub-bright adjustment in the service menu
control down until screen cut-off. (Service data Range is usually 21 to 25 in the Service menu, for Sony sets you first go to category "MCP2", & then adjustment item 01( "SBRT")= subright.
For electrical the focus, put on the screen a clear picture of your choice thru an input of the TV set from a DVD, then pause the playback of the DVD Look into each color and rock that color focus control back and forth (turn the control one way then the other way slowing down as the picture goes into the best focus. till the picture looks sharp do each color till they all look in focus. NOTE: it is best to look into each color tube to achieve the best electrical focus. For optical focus please follow the manual lens adjustment in the sets service manual

You have a projection light element out. I had the green element go on mine. I had a service agreement so a repair tech changed it.

Yellow and blue color ruins total picture on 50" tv,can't get rid


lupe0112,

I'm no expert, but I think that you have a problem with the convergence of the 3 color guns. I've been working on a similar problem. As a first step, have you tried "Magic Focus?" The Magic Focus button for the Hitachi 53UDX10B is at the left of the small front panel controls that also include your RCA composite and SVideo connectors. Let the set warm up for about 20 minutes (as recommended by the user guide), and then press the Magic Focus button. When you press the Magic focus button, the set will auto align the 3 color guns. If this doesn't fix your problem, unplug the TV for at least 4 hours and try again.

Setting color and focus inside case


The only way to do that is by eye. To Adjust the screen controls the best thing to do is turn them all down then slowly adjust one up until you get retrace lines (arched lines across the tv) then turn it down until the lines re not visible then go about 1/4 turn more, repeat this for the 2 remaining colors, after that its just done to eye for the best color. if you are still having trouble getting the color right you can go in the menu to the video settings and turn the color all the way down then you will have a black and white picture and you can adjust for a perfect black and white picture then turn the color back up in the menu.
As for the focus controls its best done by covering 2 of the tubes so you only have one color on the screen then adjusting to the best looking focus for that color. then repeat this for the other 2 tubes.
If you need more help or clarification please let me know
