Question about Samsung HCM553W 55" Rear Projection Television

1 Answer

Auto focus problem

When I try the auto focus on my Samsung HCM553W tv, it says "No Sensor Data" and goes back to tv. The picture is not bad, this feature simply doesn't work. This problem started after the tuners had been replaced.

ISn't there a remote key sequence to manually focus the screen?

Thanks

    Am I able to do this myself?

    I took the back off and cannot find anything unplugged. However I was able to get the Perfect Focus to work in 1080i on component two. The problem is the convergence won't hold. I can adjust it manually and it looks ok in 480p but looks bad in 1080i. The red gun is way off, twisted, in the upper right and lower left so there is no way to adjust it completely. Since we just upgraded to HD dish, I thought I would give 1080 a try.

    The perfect focus says "no sensor data" on video 1 (480p), component 1 and on the antenna. On component two in 480p, it says "not available". I can manually adjust the convergence and get a decent picture in 480.

    This tv is out of warranty now. The warranty company spent so much money on it that they replaced it with another tv and never picked this one up. We put it in the bedroom. I do not want the warranty repair people out again. Every time they fixed one thing, they broke something else so I will go with another service if it needs professional repair. I hate to spend a lot of money on it since it's been replaced under the lemon clause. Fixing the convergence again will cost around $300 if that's all it is.

    The last time he brought this tv back, the picture had "waves". Since the perfect focus didn't work, he re-aligned the screen by manually moving a screen full of plus signs into straight lines using the remote in much the same way as the manual convergence. I cannot find a key sequence to get back to this screen. I wonder if he screwed up the convergence when he moved this around manually?

    Thanks for all the help.

The auto focus is not actually focusing the tv. When it is running it is adjusting the convergence. Most likely the repairman that replaced your tuner didn't plug the sensor wires back in. I would call him back out and have him hook it back up.

There should be a convergence menu in the tv. Use the samsung remote and go into the menu and look for convergence.

    If have a warranty from that company it would be best to call them back out, with my company if a customer opens the set we void their warranty.

    If you dont have a warranty with that comapny then you can open the back and see if you find a wire unpluged. If you find the wire then you need to make sure that you find the right plug that it goes into, if it can fit in more than one then you will need to send me pictures of the boards in the tv so i can show you where to plug it in at. Let me know if you need more info.

You have a bad sensor, a bad digital convergence board, or the new board is not working correctly. I would start by swaping out the convergence board or exchange it for another one. Good Luck

Hi, convergence amps have blown, if you have soldering equipment and are proficient at soldering & un-soldering you can make the repair if not you need to calll a tv tech, there is also an alignment that must be done with the original remote once you install the IC`s, if your capable of this get back to me and I`ll look up the parts for you, video-tek

Picture out of focus


There will be two big Audio Amplifiers on the convergence board, they will say STK382 or some such STK number on them. Look for burned connections on the bottom of them and resolder any suspect connections before anything else. If that doesn't work, get an ohm meter across the various outputs and look for one of them with vastly different readings than the others and change the chip with the funky readings. Lastly look for the connection to the edge sensors on the sides of the screen about half way up. If that wire is disconnected it will give a very bad picture that is very similar to what you are describing.

The picture went fuzzy (color alignment).


craighirman,

try going to the antenna input from the menu screen, then trying to do the auto focus, or manual focus. My Samsung won't let me do the auto focus unless I'm looking at the antenna for some strang reason.

Samsung rear projection tv has multiple images with differnet colors


The auto self focus screws up if the picture does not remain constant or close to it while focusing. It is designed to self focus every fifteen minutes. Go to menu and then setup and turn the auto focus feature off. I have had mine off for the past year and have had no problems. If you slide the bottom portion of the remote down you will see a self focus button. My suggestion is to put a DVD in and hit the pause button during a scene and then hit the self focus button. It should align back up and may take a couple of tries. (If you have an aftermarket remote, just enter the menu and then setup and you can activate the self focus feature, just don't turn it to auto focus!)
