Question about Samsung HCM4215W 42" Rear Projection Television

1 Answer

Samsung HCM4215w has wavy red lines and bowtie effect

I ordered a new convergence board in an attempt to correct problem and same problem. I have a new one on way but don't want to waste it, is there a way to reset tv back to factory setting before I install new board?

    thank you very much. It could be my inability to adjust but after installing the new board I still had red line and "ghosting". All of the points when in convergence are adjustable but I can't seem to get it lined up properly. Probably just need tohave it looked at before I mess something up. Again thank you

    The picture is out of wack. It appears that there are two colors that are projecting wavy lines and the Perfect Focus will not correct the problem. This happened all of a sudden. One day the picture was fine and the next day when we turned the TV on, the two of the colors appear wavy and the overall picture is out of focus. What could possibly cause this probelm? Where would I buy replacement parts to fix it? Is there a shop manual available that defines the process to correct the focus of the picture? Would the cost to buy replacement parts cost more than buying a new 42 inch TV?

Are you saying that after installing a new convergence board, you still have the same issue? If that's the case, another new board isn't going to resolve this. Also, you can't do a factory reset. Doing that would lose all the convergence and geometry data in the TV and would require a qualified technician hours of work to restore the settings. If you've installed a new board and have the same problem, suspect a problem in the TV's power supply. All convergence circuits require 2 voltages to operate. There will be a postive and a negative voltage of the same value. If you're missing either of these voltages, your convergence will never work properly.

Intellesence cant correct wavy color ghosted images on my screen. attempted to manually adjust and line up the colors blue will adjust but red will not.


Projection TV sets have two very common problems listed below.

Problem #1) Convergence


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 more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*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

Color blends together. Picture has a curve on top of screen.


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

Wavy red lines ,double vision


This is a convergence problem and if you can solder, you should be able to fix this yourself. First open up the back and locate the convergence ICs. These are large black ICs attached to a heatsink and should be marked STKxxx. Post the markings here and I'll confirm you have the correct ones. Try resoldering the pins on the ICs. If that fails to resolve the problem, you will need to replace them.

Keep me posted,

Unplug the power.

Remove largest plug from convergence board. Plug in TV, see if it starts. If it does, then a convergence IC is are shorted.

Fine Yellow Lines


The lines I believe are retrace lines (if I interpert correctly) and may or may not be corrected by turning down the screen controls red green and blue. But first I would see if the 200V source that feeds the video outputs on each crt board is there or low. If so the problem would be a resistor or 200-250V capacitor that feed them. (200V source usually off the HV transformer secondary.

Color alignment problem


You will need to put the unit into wahts called service mode because it will have to totally realigned since you change the whole module you changed the chip that had you stored memory setting for convergence called an EEPROM. here in the shop I would unsolder the old EEPROM and put it on the new BOARD. Also on most models you don't have adjustments for the green you have to move red and blue to match green. Imay want you to describe again to me what you can adjust now with the new board in the unit can you move all colors left right and up/down
