Question about Samsung HCN653W 65" Rear Projection Television

2 Answers

Samsung HCN653W 65 in.!

My set has annoying lines that run accross my screen from side to side, about 2-6 inches wide and they have a brighter picture to each line. I tried all the inputs, and its the same if your watching a dvd, or sat. I ajusted the brightness way down so i wouldn't notice them as much. Also when there is wording on the screen, it creates bars that are darker all the way accross the screen for each line of wording. It seems that those bars are the way the picture supposed to look. before i call to have it looked at, i wanted some ideas of what it could be, so i'm not fed a bunch of bull. Is it something i can fix myself?? i build cars and bikes for a living so i'm handy, i just don't know where to begin and don't want to make the problem worse. Is it fixable?? or worth it?? i hope so i love the tv!

Sounds more like a power supply issue than a convergence problem. Do these lines move and go from bottom top the top slowly or from top to bottom?

My first guess is it kind of sounds like a convergence board problem i know they had some service bulletins on them. hope that helps oh and convergence boards arent exactly cheap and will probably require some soldering

My Samsung HCN653W 65-Inch Widescreen Projection HD-Ready TV has a 3d like picture when it has been on a hour it goes back to normal

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

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. In some cases the TV will also not show any video. 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, wavy, or has a shadow or shadows
  • 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 pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Double Vision & Bowed Screen

Chances are that the convergence amps are bad.
If those are mounted on a separate board, replacing the board would be the easiest thing to do. Running the magic focus or touching up the convergence in the customer menu may be required.

Red lines when watching DVD

Regardless of what inputs you use when the lines appear, that symptom suggests that the Proscan Module Samsung p/n#BP95-00140T is probably defective. That board is a plug and play replacement but there are no short-cuts to testing it to be certain that's the problem or the entire problem. That said, the top of the metal shield lifts off and the board can be pulled with no greater skill than a first year technician. The board is $184.25 plus shipping from Vance Baldwin - so if you're feeling lucky you could try this one yourself... Just be careful. If you have ANY questions drop me a note at and include the model number. Hope this helps Bill Good luck

Samsung HCN653W Transport

the bottom stand seperates from the top screen portion. On the side under the top potion you will see 4 black phillips head screws on each side. Remove those. Also there is a small access panel on the right side ( if your facing the tv ). There are 2 screws there, remove them , and look inside , you will see 3 plugs. Unplug them. Once you have done all this, have someone help you and lift the top portion off.

Bad signal board or something else?

You weren't very specific about your problem, but assuming you've tried different inputs and tried messing with the convergence setting, it may indeed be the signal board, and you may need to have it replaced. BTW these sets also have an issue with the dynamic focus circuit and with crt fluid leakage. Make sure that you do not have a fluid on one of the crt boards. And as always with repairmen, a second opinion couldn't hurt.
