This is by far the easiest repair of any TV with a convergence problem.... Replace the CG amp board part# BP95-00142E Both STK's are on the board(no messy soldering),five plug-in connectors,mounted with only one screw away from the chassis in plain view,no alignments necessary - the whole repair takes about 15 mins and the board sells for about $80 !!

Your other model was more than likely a CRT projector where you coulod manually align the Red/Green/Blue guns. The one you have now is more than likely an LCD projector which can't be readily aligned. Sounds like the panel is failing.

My screen has a red tint to it. It used to wear off after the tv was on for awhile but now its red constantly.


It seems the HT Transformer (High Voltage) transformer is unable to supply the desired voltage to the picture tube. It was probably ebbing giving rise to the the red tinge earlier when starting up but easing up as the tube got heated up, however now the voltage has really dropped. Since the tube works by displaying a combination of RGB(red, green & blue) to make up the complete spectrum of displayed colors either the HT transformer &/OR the tube needs to be changed.

Why does my projection look green if the colors are right on the computer?


I'm going to guess that you are using an RGB cable to connect to the projector and the projector is expecting a composite signal. The composite signal would be what uses a yellow connector when you use hte red/whjite/yellow type of cable. All of the video is carried by the yellow. If the projector is expecting this and you send out component (RBG in this case), then the only video signal processed is the green. Since the green also contains the sync signal, the picture will be seen but green.

Check the menus on the projector. You should find a video selection area that will allow you to change to component input.

Please update this if you have any more questions.

Not real colors. maybe no green color


Projection TVs display using three separate color tubes red, green, blue. The less likely scenario is the tubes being out of alignment. Most likely scenario: the green tube is leaking/failing.

Unfortunately, there are many complaints regarding a color tube giving out on these types of TVs.

You should be able to search the internet for instructions on replacing the color tubes.

I was just given this t.v because friends couldn't figure out what is wrong with itl. The colors don't line up right,looks kinda blurry depending on the lighting of the program being watched. How do i fix...


According to the manual:
1) go to the "TV Main Menu"
2) Select "Screen"
3) Select Adjust Projection TV (obviously only if a projection TV).
This then allows you to adjust the TV's 3-colors. Selecting GREEN CENTERING brings up a control panel that lets you center the green projection tube on the screen. Selecting RED CONVERGENCE or BLUE CONVERGENCE lets you align the Red & Blue projector tubes. Centre the green projector tube 1st. Then adjust the red & blue until the test pattern on the TV screen appers white.
Good Luck!

Popping; sparking of Red Projector to metal frame


Sounds like the red CRT has an internal short. Sometimes happens that the picture tubes develop an internal short and cause arcing. I world CAREFULLY disconnect all of the wires to the CRT and see if the arcing goes away. VERY IMPORTANT!!! there is a high voltage wire attached to each pictur tube, usually a red wire that goes to the side of the tube. You can get a shock even if the TV is unplugged, as the tube will hold a charge for years after the power is disconnected. If you don't feel comfortable doing this, DON"T since the shock is powerful enough to stop your heart.

Colour problems with projector


In short If the reds show as red, The greens show as green & Blue shows as blue. I would say thats as good as it can project. It's hard to judge color without seeing it for ones self but usually DLP projectors that use a colorwheel do not have perfect color.
