    Problem seems with light-engine as Lamp is still OK.
    Please contact Hitachi Service and I'm sure this would be costly repair.

Doing the adjustment is not actually a fix, all that does is change the drive amount of the green CRT which allows the set to work but the 3 CRts will be out of balance so picture color will be affected. The only way to repair a bad CRT is to replace the CRT itself. You can get replacement Green CRT from www.tvrepairworld.com

You need to adjust the Green Screen Drive Located on the Focus/Screen Control Block Their will be 3 on Top to adjust Focus to each Tube R/G/B and under it is 3 Controls to adjust Screen Drive to each Tube R/G/B . Cleaning the mirror and Top of Tube Lenses will help improve Picture also if they are Dirty. Control Block is Located behind Front Bottom Panel Pull it off and you should see it.

My color seems to be more green than should be and I have tried to reset the color with no help


You have a focus/screen control box Find it and adjust the R/G/B screen drives When you first start Go to Menu turn Color off then with a mirror adjust the picture as close as you can to a black and white picture R/G/B screen drives, the little control box you are looking for will have 3 controls on top for focus and 3 controls under them for screen drives to each tube red,green,blue after you have adjusted to a black and white picture then go back and turn color on.

My convergence is fine but after professional replacement of the board there is a slight bowing and slanting of in-screen borders and some channels have a little distortion at the top of the screen. The...


First: If the convergence board was replaced--the set may need a total adjustment---this is why most good techs replace the convergence chips and any bad parts instead--also costs less----Second: to enter the service mode (it is done with the set already turned on) should be Mute, 182 or Mute 183---if you get the convergence mode--7,8, 9 will select red, green, blue, 5 will stop the cursor from blinking and allow adjustment---with the cursor blinking 2,8, 4, 6 will allow you to navigate---depending on the remote used--the P mode button will take you across the screen in a series of steps--the remote I use for this has a button on it marked data save--this saves the adjustments. Your remote may have it or a different button for this.

Understand---if you get into the convergence mode---Green determines if the geometry of the picture is straight---red and blue are adjusted to it---to align the green you need to call the convergence mode up and then cover the lens for the red and blue---leaves you with a green grid---then you need to select green and wherever the grid is not straight adjust it--once you get it straight you need to uncover the red and adjust it to the green, and then the blue to the green---green alignment determines if the picture is straight---It sounds like this guy did not try to get the green straight and just adjusted the red and blue to whatever the green was.


My point here is if you paid money for this repair--either he aligns it straight or you should get your money back----GREEN never needs to be adjusted unless the dcu(digital convergence unit that stores the adjustments) has been replaced or the Convergence module has been replaced---I bet if the original convergence module was repaired(chips replaced etc) and installed you would not have this problem.

If the guy replaced the DCU then GREEN must be fully adjusted for a straight picture FIRST! then red and blue adjusted to it.

It is not easy or quick to Adjust the green--maybe he just wanted to get out the door?

I do this here for free so if this has helped you take a minute and give me a vote here.

If you have any questions or need help reply to this post here.

Red , Green And Blue.


Heres the best way to set a phillips screen controls. Go into the picture controls and set picture or contrast to roughly 75%, then set brightness to 50% and then set the color level completely off. Then adjust the screen with the 3 color controls untill you recieve the best black and white picture as possible. If you are unable to achieve a good black and white picture change the coolant in the green and blue tubes. But if you can get a good black and white picture stop there then turn your color level back up and the picture should be correct. Let me know if you need further assistance.

Try this procedure:

Adjust the green & blue CRT screens to match the red. Go into your picture menu adjust, turn color all the way down to a black & white picture. Now adjust each CRT screen so that you end up with a true black & white picture. Then adjust each focus control to get a sharp picture, and adjust each CRT focus one at a time for clarity by covering the other two up. Then go back into picture adjust and turn color half way up, you should see a better picture.

If you cannot get the blue & green to even out to a black & white screen you have other problems such as faulty CRT card on back of tube or it could even be that the video IC is faulty. If this is the case, then you may have to get a competent local technician to check the TV and get the necessary parts replaced. It could set you back between $200-$400, depending upon how many components need replacing.

You can also try a hard reset..Unplug all cables, including power from the back of TV. Wait for 4 hrs and reconnect them. Try and see if it works now.

Hope that helps...Should you have any further questions, please feel free to post them here.

Green picture


Hi,
I'm not sure about this model but most projection tv's have a focus/screen control block usually located behind the front grille where the speakers are. The grille usually comes off easily. If there are no circuit problems you can adjust the red green and blue picture tubes there. Also the focus. It will be written somewhere screen and focus: Three for screen and three for focus. If you find the screens then adjust them slowly clockwise for increase brightness on the red and blue and you may have to reduce the green. Adjust for best picture. If the picture does not adjust too good then the tubes are weak. Only if there are no circuit problems Hope this helps

Green Picture.


i suggest to have it check by a qualified service technician. there seems to be a problem with your crt (cathode ray tube). because inside this projection tv are 3 crt guns responsible for color red, green and blue, which only qualified technician can adjust it and replace if it is necessary.
