Question about Samsung HCL4715W 47" Rear Projection Television

1 Answer

Picture Problems on HCL4715W

Today we came home, turned on the TV and the colors were no longer aligned - it looked like red, green, and yellow had separated. I found on this site that I could do some adjustments hitting mute-1-8-3. However, I have no idea what I'm doing when I go into that function. And then I hit some button while in that function that caused the green to be blurred (for lack of a better word). How do I get the blur to go away? And is there anywhere that I can get some instruction on using the mute-1-8-3 function, or can someone give me some advice on fixing this problem? Thanks for any help.

Most likely the convergence ic'd failed. Do not adjust the convergence until the ic's have been replaced. Most likely the ic's are all that failed but all resistors around the ic's should be checked to make sure none of them burned open. It is reccommended to replace both ic's. This is not a difficult repair if you are compentent at component removal and soldering, but a qualified service professional is reccommended.

How can i connect a video camera to play through tv. my camera cables are red-white-and yellow. tv. is white-red- green-green-and red.

Your camera has three cables, red and white for stereo audio, and yellow for what is called composite video. Composite video puts the three color signals into one composite signal. Your TV sounds like it has a component video connection, which wants all three color video signals separated onto three plugs. They are usually color coded green, blue, red. Not sure if you mistook a blue outlet for green..... In any case, on my TV, it will allow me to connect a yellow composite signal to the green component jack, the first (leftmost) of the three component video jacks. Not sure if your TV will work this way, but it is worth a try. Otherwise, you can look up accessories for your video camera and see if it can output true component video and stereo audio, but I tend to doubt it will.

How do i wire red white and yellow rca to an xbox 1 av plug. my av plug has blaack white orange and green wires

In the old school standard AV: Red and White are usually audio channels (Red:Right - White:Left), Yellow is video.

Orange can be coax audio, (both L&R channels in one cable). Before digital (optical) came out, some receivers actually had a coax (orange) jack in the back. Radio Shack sells a splitter if necessary.

In higher resolution systems video is separated into three colored cables: RGB or Red, Green, Blue
called 'component' video. The green cable carries Yellow, the blue cable carries (PB) Blue and the red cable carries Red (PR). And with today's tech, the component signal is carried YCBCR as (digital video.) cf.

Component 'wire colors' are there just to remind us. If your TV has "Component" input. Try green to green, white to yellow and black to red. Orange to audio (splitting L&R if necessary)..

Convergence problem TV won't let me align the

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs. To get fixed either call in a local TV repair company or goto sites such as Tv Repair Kits to get a repair kit with instructions. Here is there link.

They have put together complete kits for most models that include the parts, step by step photo instructions, repair assistance, etc.

Blurry and colors are seperated red green white

if you are viewing from a projection tv, chances are you have to go thru the menu of the tv to 'picture tuning'. here it gives you different things that could be fixed. one to look for is 'lamp alignment'. It should show all the colors and lines with directions to bring them into focus. This should fix the blurriness and 3-d red/green/white separations. hope this helps you!

After a few minutes the color goes to intense red and green

My tv didn't turn green, but the red separated significantly. It started off happening after a few minutes of being on (I suppose the defective part was "warming up"), then it got to where it was like that immediately upon turning the tv on. In my case, I had to pay a tv repair man $350 for a new part. There are 2 microcircuits that control the color alignment--one that controls the red only, and the other controlls the other 2 colors, blue and green I believe. Maybe your part is the blue/green controller, mine was red. The repair man said these parts fail so rarely they don't stock the part. The cost of repair may be different for a different part, but either way you have to choose if it's worth that cost to you. If you get rid of it, I'll buy your tv stand ;-), I bought mine from a friend and didn't get the stand in the deal.

Toshiba TP50G50 Theaterview picture is double with red color only

Your alignment is off. Go to the set up menu then convergence. hit right and you will be in the convergence menu. select the color that is not in alignment. The green line does not move. if blue and green are lined up the line will be cyan. if red and green are lined up the line will be yellow. when all three are lined up the color will be light. Best of luck!

Warped Picture, Separated colors

Each color (red,green & blue) has an amplifier IC (STK-).
When there is a convergence issue,the first step is change both
IC's for reliability. Then check for open fuses devices,usually
pico fuses.Then re-check convergence alignment.......T.
