Question about Samsung HCN4226W 42" Rear Projection HDTV-Ready Television

Samsung Convergence Problem

Would the bowing, (geometry problem) be a convergence issue as well? Thank You,

Can I get a screen jig anywhere, or would I have to go to Samsung?
Looks like I need to adjust the screen with it after replacing the board.

Thanks

brent hardin,

Your description of the problem sounds like a convergence issue. You more than likely have lost the convergence ICs. They will need to be replaced and the convergence will have to be set. The green beam should not move. It is the standard which the red and green are moved to overlap. Since you have bow at the top and bottom I would replace the convergence ICs. I have a tip at http://www.fixya.com/support/r4220499-change_projection_tv_convergence_ics which explains the problem, how to replace the parts and where to get the replacement parts.

Thanks for using FixYa and for the great rating. Great ratings will keep the experts helping to solve problems. Thank you.

Bowed Picture; Still have access to convergence. HELP!

The convergence power supply board is usually the cause of that problem. You can get the replacement Convergence power supply board from www.tvrepairworld.com

My 57hx81 has a slight concave bow in the middle top to bottom

Sounds like a problem in the vertical sweep circuit. Check voltages to your convergence ICs. If they are not to spec then look for bad fuses and capacitors on the power board. These will throw off the DC voltage to the convergence chips causing the bow effect. I've had a single bad pico fuse ($1) cause this symptom.

The problem you're having is due to the failure of the convergence amplifier circuit. In that circuit are some components which amplify or control the signals to the dynamic convergence yokes, which line up the red green and blue images to superimpose them over each other to create a proper colour picture. When you get a failure in that circuit, it no longer aligns the images properly, and generally you get what appears to be badly set geometry in multiple colours. In some cases you will also get a problem with the part of the power supply that supplies the convergence amplifiers, or the digicon, which is the digital convergence control module.

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.

Samsung HCM4215w has wavy red lines and bowtie effect

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.

Samsung pcl5415rb convergence problems

If you bought a kit from sites such as TvRepairKits.com go back and ask for help. If you bought the parts over the internet without instructions you have two common problems...1) Bad/Fake chips... or 2) You did the repair wrong - because you lack proper instrucitons.

Pico fuses - yes - they can be one of many secondary reasons convergence is not fixed on Samsung models.

Green bow tie, convergence not helping

Yes, your geometry correction has failed and you will need to seek qualified tech for help. You need what are called STKs and you should be able to get the job done inhome for under 300.00

Red convergence is bad.

Hi, you need to change the convergence ICs , STKs: and some resistors,low values; , after changing them, you will have to go into the service mode, to do some adjustments.that's it.

Convergence - bow problem

If you know how to solder on a solid state pruinted circuit board, try to first resolder the convergence IC's. There are two of them, they are black and stand up on a metal heat sink. The IC's will start with stk and have some numbers following that. Sometimes you can get away with resoldering BUT most of the time they have to be replaced. Consult a trained service person if you dont have any TV repair experience as thei like I said is a solisd state set and trhere are really no user replaceable parts inside of them.

The audio on my Samsung TV does not work. I took it apart and checked the speakers, which work fine. I've tried using the remotes buttons, TV buttons, Pressing mute/un-mute, plugging in a DVD player to tryaudio on input/av1/av2, also I didn't mess with it for a couple months hoping it would magically work. What more possible resolutions or tricks are there to try? 42in., rear projection TV, silver, and it is a Samsung Model# : HCN4226W. The quicker i can get some help the better because I would hate throwing it away.... Thank You
