This set uses either 2 of the STK-392-020 OR -40 CHIPS. Both will have to be replaced and the set adjusted with the remote.

There are two versions of this set, one is very easy to get at the parts and would be a do it yourself job.

See attached photo of what part looks like (set has 2). In the easy version with the back removed is a small circuit board mounted well above the boards in the bottom (about 8 inches wide and 3 deep) and a few screws and some plugs and it comes right out.

A pair of the chips will cost less than 20 dollars---there are some resistors that need to be looked at and usually two fuses on that board (not glass but easy to test)

If this information told you something you did not know, rate this solution as very helpful as I do this here for free.

i have a samsung HCL4715WX/XAA - c610e9e.jpg The -020 and -040 are the same but the -040 lasts longer and is a higher current device.

I have a60 inch hitachi projection tv. I tried to fix the screen alignment using the grid but the blue line doesnt move to line up on the grid. The green and red work fine. So theres a blue ghostly glow...


you will need convergence work done & for Hitachi I recommend a professional as the convergence will have to be reset for normal & HD pictures. See if you can get a quote from a local servicer.Be sure you are sitting down.
I really think your money would be better spent on a 21st century LED or LCD TV.

"Perfect Focus" problem on Samsung HCN4727W


You have a bad sensor, a bad digital convergence board, or the new board is not working correctly. I would start by swaping out the convergence board or exchange it for another one. Good Luck

Horizontal lines can be cause by many things. One of which is the convergence module. $130.00 is a little high for something that can be caused by other things as well.

Color and images


Projection TV 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.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • 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.
  • TV shuts off after powering on. Power light will blink. 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. And you should be able to get the grid straight.

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 flash 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 fix

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

OK, Its always best to replace the lens assembly if its not preforming well. never dump the fluid. just replace the lens. As for the double images and the misalignment of the blue convergence line, this is caused by a faulty convergence chip that is located on the convergence board. you will need to replace this board in order to restore proper convergence performance.

you have a failed IC resistor usually you can physically see the bad one because it burns out leaving you to guess what the value was. Hitachi offers a convergence fix kit which has 2 IC's and all approiate resistors.

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


To adjust manual convergence on your projection TV, follow theses steps:
  1. Turn your TV on.
  2. Let it warm up for 30 minutes.
  3. Press the Menu button on your remote. The Main menu appears.
  4. Use your remote to select Function, and then press the joystick.
  5. Select Convergence, and then press the joystick. The Manual Convergence screen appears.
  6. Select Red, and then press the joystick. A series of crosshairs appears on the screen.
  7. 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.
  1. 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.
  1. 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.
  1. Repeat for all outside crosshairs, and then for the inside crosshair.
  2. Return to the Manual Convergence Screen, and select Blue, and then press the joystick.
  3. Repeat Steps 7 through 10 for Blue.
  4. 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.
