Question about Samsung HCM553W 55" Rear Projection Television

1 Answer

HDTV 1080i or HCM553W blue and yello ora around objects

I've had this TV for quite a few years now and this just happened recently

I had blue double vision on the screen so I did a bit of research on it and changed both the stk392-040 chips with brand new ones and the problems is a bit different now it looks much better but around every object there is a blue tint to the right of it and a thinner yellow tint to the left i was certain changing the chips would fix the problem but now uncertain what is wrong any suggestions would be much appreciated.

Thanks in advance

You are going to have to reconverge your TV. Order a service manual and it has a 20 page set of instructions on how to set up the convergence for the first time with new convergence amplifiers. Once you have done this procedure the "perfect picture" one touch control should be enough to keep it in convergence. You must have the original remote control in order to do the convergence procedure.

Good Luck.

Upgraded to Hd and tv started messing up. Double images for first 10 minutes and sometimes tv picture goes off and lines up and down.


Your HDTV is capable of up to 1080P resolution. SDTV (standard def) signals are 480i; EDTV (enhanced def) is 480P; HDTV are 720P, (there is no 720i) 1080i and 1080P. Generally, those modes ending in "P" look better than those ending in "i". 1080i is the highest possible for broadcast TV, but BluRay disks and Directv have 1080P display capabilities.

The double picture you're describing sounds like the TV is set to display only standard or enhanced def signals while the Dish Network box is supplying it with HD signals. You should locate the control for the TV's resolution and make sure it is set to "1080P" and then set the output of your Dish Network set top box to the highest output it offers. Do the same for your BluRay player and any other devices, too.

Once set correctly, you should have a great picture once again. I hope this helps & good luck!

How do I change my W2613 TV resolution to 1080i? I just bought this TV a few weeks ago and I want to be able to play my XBox360 in HD and when I connect all 6 wires (Red, White, Yellow & Green, Red,...


use just the red green and blue wires for the picture and NOT the yellow wire. That is why it is messed up.

XBOX games only play in 720, but it will still look great.

Convergence panasonic HDTV 1080i bbe hi definition


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

Double vision on my samsung HDTV 1080i


If one or more of the colors, red, green or blue have separated from each other and you can`t correct the problem using the convergence procedure as described in the users manual, that would indicate you have a convergence problem. Bad solder connections on the convergence output chips are common. If the set had a rough ride down the stairs while moving, that may have facilitated in exposing a preexisting condition. However, the most likely cause is the natural failure of one of the convergence output chips and or related components and not the move. The fix is to have a qualified technician address the problem. This is not a do it yourself job.

Replace the convergence ICs. you will need two of them. They are located on a large aluminum heat sink with STK numbers. They cost about 10.00 each. They need to be soldered in. Its an easy repair if you can solder. Let me know if you need any additional info.
