1st guess is bad convergence ic-either IC804 or IC805. Both are part #STK392-110. May be bad connections in convergence circuit, or open resistor(s) As for too much green, not sure, shouldn't be because of convergenece circuit, possibly green CRT screen voltage needs adjustment.

Mitsubishi WS55859, was getting 2 and 2 blink, replaced the pico fuses and convergence chip - 3 times, each fix worked better than the next but evenually failed - now have it working, trying to adjust...

The most likely cause is shorted convergence chips and possibly a few pico fuses.

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 Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with 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 - TV Shuts down - May also make a constant 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

You can see some more examples and find a fix here

Green convergance wont adjust, bowed screen

Green really shouldn't be adjusted, you adjust red and blue to the green. When a color is bowed that indicates that a part or two are bad, probably the convergence output IC's and possibly a fuse or fusible resister. You may need a tech to come adjust it for you because after replacing IC's the adjustments should be done in the servicers menus not just in the consumers menus.

Red,Blue,Green Image

YOu have convergence issues. Ok first question. IN your setup menu do you have the convergence option/ if you DO not then it can be a specail fusable link. fl231 if you do. next question do the picture bow in at the middle. if you do then it possibly a convergence power supply issue. next if you go into setup convergence does the crosshairs adjust up or down left to right on both blue and red. I if so then theres is a chance that it can be a convergence adjusment or a amplifer problem AS always THIS SET CAN GENERATE LEATHAL 380 VOLTS EVEN WITH SET UPLUGED SO BE CAREFULL.

Mistaken: Not the green gun convergence at all. confusion sets in...

the problem you are having is the convergance amplifiers have failed and may be some support resistors and pico fuses. the amplifiers are STK392-110 but STK392-120 can be used and are better for load handling. these are located on very large heat sinks. there are two of these IC's and both should be replaced.this is the most common failure in a projection tv. if you got into the service menu for multi point convergance setting you may have place the data well outside the tolerance of the amps and they may blow again. if you did not get into the service menu reset the convergance to factory reset (this is in the cutomer menu) before you replace the amps. the panasonic part # for the amps is C5AA00000203 . you can get it at www.vancebaldwin.com . if you don't have the skills to repair this then you a tech should be called the cost of the repair maybe around $350.00 to $375.00

Fine tuning grid on my Samsung HDTV with remote.(BP59-00048)

To adjust manual convergence on your projection TV, follow theses steps:

Turn your TV on.
Let it warm up for 30 minutes.
Press the Menu button on your remote. The Main menu appears.
Use your remote to select Function, and then press the joystick.
Select Convergence, and then press the joystick. The Manual Convergence screen appears.
Select Red, and then press the joystick. A series of crosshairs appears on the screen.
Select one of the outside crosshairs by moving the joystick up/down/right/left or by pressing the 2 (up), 4 (left), 6 (right), or 8 (down) buttons on your remote. The method you use depends on the model of remote you have. Note: You must do the outside crosshairs first.

In the crosshair you selected, if you can see a horizontal red line, use the CH up or CH down buttons to move the line so that it is superimposed on the horizontal center line of the crosshair. Note: Make the single horizontal line as white as possible.

In the crosshair you selected, if you can see a vertical red line, use the Vol + or Vol - buttons to move the line so that it is superimposed on the vertical center line of the crosshair. Note: Make the single vertical line as white as possible.

Repeat for all outside crosshairs, and then for the inside crosshair.
Return to the Manual Convergence Screen, and select Blue, and then press the joystick.
Repeat Steps 7 through 10 for Blue.
Press the Menu button on your remote to exit.

Important: The directions above work for most Samsung Rear Projection TVs. Yours may be different. For exact directions to perform manual convergence, see your user's manual. If you don't have your user's manual on hand, click HERE to view your manual on line.
If you cannot get your Projection TV to converge, it may need to be serviced. To arrange a service appointment, call Samsung Customer Care at 1-800-Samsung (1-800-726-7864). Have your TV's model number and serial number on hand when you call.

HCM4215W Green convergence problem

Hi Greg,
Sounds like you have a bad convergence chip in the convergence board. Unfortunatly, about 80% of the rear projection sets I work on have this similar problem. I suggest that you change both chips ( there are 2 of the same ) and remember to use heat sink compound as this is why you not have the problem ( excessive heat destoys electronic components). Good Luck
