I own a Samsung Rear Projection HDTV 1080i
Serial Number HCM 4216x
Svc HCM4216xx/xac
type # CM4 2X5
120 V 60 HZ 240 WATTS.
We are experiencing a colour differentation across the top of the
screen in the form of an arc. The image above this arc line is tinted
yellow,, while the rest of the screen is as it should be. I'd like to
know if there's a part I can obtain and replace without having to call
repair, most of whom want min $300,00 to fix.
I have a picture of what the screen looks like but can't attach it to
this message.
This is the convergence IC's that are causing this and if you can replace them( unsoldering and soldering them ) then going to an electronic parts store to get your IC's for your set is what you will need to do , here is an example of the convergence IC's http://www.nteinc.com/specs/7100to7199/pdf/nte7178_81.pdf
if you need further assistance then just let me know and i will help
otherwise hope this info is at least worth a fixya
if you have never soldered then you will want to practice before doing a repair like this , also practice removing solder from a broken device or board with some solder wick
you will have to look at the numbers on your chips that are on a big heat sink , to get the matching or upgraded chip set , they will look like the example IC's link that I gave you , so finding them will not be hard at all, just the removal of them

The part replaced is the blue convergence IC, part number usually
STK392-040 .A generic IC will last 10-12 months.You must have
OEM or better quality for durable repair. I use Panasonic brand.
Change both IC's for long repair duration.
ok you have defective convergence crrection circuit! or maybe the RF Box is defective! can you describe the color of the ghost?

Thankyou for the information. Which chip would I use for the tv mentioned above? Also.... is soldering difficult?
