Question about Samsung HCL4715W 47" Rear Projection Television

1 Answer

See lines in HD cable or DVD source images, also maybe a problem w/ color, see extra blue haze

Model: HCL4715W Service Model: HCL4715WX / XAA Ok, I don't know what I'm talking about here. TV was fine earlier today, then suddenly the cable image looked funny, could see lines in the screen was the first thing I noticed. I figured my daughter accidentally hit the 'zoom' image or something, and didn't have time to look at it. Now, coming back home, and looking at it again, not only is there lines in the screen, but the picture is a bit hazy w/ extra blue being seen as a shadow to the main images. Checked the cables, ran a DVD and had similar problems, so it's not the cable box, or the cables. I've seen this kind of problem before, at least w/ the color, only to realize in sliding the tv around one of the 3 component color cords was coming loose, pugged it back in and it fixed problem in the past... but that's not the case now... I recently re-wired everything adding a receiver, but was still sending the video images via component cables in each case from the DVD and the HD Cable box directly into the TV, so I can play music on the receiver while still watching TV, so it's not a problem w/ the receiver. I tried the perfect focus, but that didn't do anything. I looked at the convergence thing, but don't really know what to do with it. The TV is almost 5 yrs old, maybe I have a bad bulb or something? Any troubleshooting tips to try to narrow it down, and hopefully fix it cheap myself???? Thanks, Karz

Re: see lines in HD cable or DVD source images, also...

It sounds like convergence problem to me. There are two ways to correct these concerns; Samsung does sell boards, so if you are handy you can replace the boards yourself. BUT I recommend calling a factory authorized service company. It isn't costly, the cost will run around $400 -$550.

Picture Moved Up

Check the cable and connections between the TV and your cable line. Make sure the contacts are clean, no bent pins, etc. Try replacing the cable if possible.

Our samsung HCl4715W tv is all connected right but our picture is scrambled where you see double exposure and the color is off. Can not find our manual. any suggestions?

The problem of your tv is the convergence. Projection tv set has a 3 colors red,blue and green this 3 colors must be properly lined up to look the video normal. When this 3 colors is not properly aligned the video will produce a double image of color or like a 3d or wavy. In order to fix this problem you should adjust it in the menu program of your tv you should move any of the colors to up or down, left or right if you cannot align the 3 colors the problem is the convergence ic it must be replace. To locate the convergence ic you should remove the back cover of your tv but be sure to unplug your tv, you will see this ic attached in a large aluminum plate it has a marking of stk--- and followed by a numbers. or you could contact a service technician do do it for you and save you from stress. Good day and best regards.

Toshiba 57HX81: Green works but Blue and Red seem to be out.

Do you still have reds? Is the image still clear though discolored? If so you ought to replace the blue bulb which has most likely failed. The part no for the 57HX81 model blue CRT bulb is TOSHIBA     23008753.

Toshiba 65H80 has yellow hue.

Check you HD inputs or source. Sounds like the red stream is missing; maybe a loose cable.

I have a samsung sp42q2hl, which on the front of the tv say's it is a hdtv ready, and yet i cannot watch high defenition images or movies, also there is no hdmi inlet at the back so i'm not sure how you...

Use component to connect this will give yu HD picture,
On the back of the set you will see A group of 5 phono sockets Blue, Green, Red, These carry picture,

Then Red, White, these carry stereo sound.
Component video 0831d.gif
Component-video cable b.gif
Component video improves the picture quality even more by not only separating the color from the black-and-white portions of the picture but by further splitting the color information into two color-difference signals. When the picture signal is split up in this way, you get an unfiltered, uninterrupted image, with better resolution and greatly improved color saturation. And this is why component video is the predominant method of hookup from HDTV set-top decoders to HDTVs.

So this is how your set can produce HD picture from Hd source.

Loss Of Blue Color

The loss of blue could be one of 3 things. First of all if you are connected to a HD cable box or a HD sat. recvr. using component cables. Make sure the BLUE connection hasn't fallen out or is loose. The possibilities is the blue CRT (picture tube) itself or something in the blue CRT driving circuit.
