Question about Samsung HCM4215W 42" Rear Projection Television

1 Answer

TV Screen Randomly Goes Dark with Red Image

I am using my Samsung HCM4215W in "component" video mode (RGB) for both my DVD and cable connections (I have 2 separate component video inputs)

Regardless of the input, my TV from time to time goes dark with a residual red shadowy image. So far, it generally recovers in a few seconds, but sometimes it stays that way for a few minutes and then recovers.

I've run the auto-focus feature and that seems to run okay when the TV has recovered. I've tried running the auto-focus feature when the screen goes dark and it cannot complete the full cycle of tests (gets to about 25% and restarts the cycle)

Any suggestions?

    I am having the exact same problem with a 4-year-old Mitsubishi WS-65313. The screen looks perfect and all of a sudden goes dark with a red shadow-like picture. If I have the patience to wait it out, the screen returns to normal. This is happening more and more often with longer recovery times. I'm afaid that there's a simple solution that I don't know about, or if I have a tech out to fix the problem, it won't happen while they're here.

SAMSUNG LD TV - VIDEO PROBLEM


Make sure that your video is connected to the video port on your TV. Also check to see if you are using the proper channel (component) on your TV.

Most issues occur when the cables are plugged into the wrong port. Some are color coded. Red goes to red, white goes to white and yellow goes to yellow.

I have picture but no sound. We just had our surround sound system go out and are trying to run our tv on it's own internal speaker system. How do you hook it to our direct tv hd box


Hi.

You need to use audio cables. Connect two red and white audio cables from the output on the HD box to the relative input at the back of TV (nr.4 in picture below). The best way to connect the HD box is by using component cables, that are the red-green and blue trio of cables, plus a white and red audio cables.

Here what you need:

Three plus two:
Component Video Cable
Audio Red / White Cable

or single set of five:
Cables Unlimited - Video / audio cable

Once you have the five cables, connect them to the output at the back of the Direct TV box, and then connect the other end of the cable to either group of connectors 6, or to one of the columns in connector 7. Do connection with box and TV power off. After re-applying power use the source-input selector on remote to select the source from Direct TV box.

How do i get 1080i, my tv shows im only in 480i. i think i might have it hooked up incorrect. my other tv of another brand is much newer so all i did was connect the hdmi cable from the tv to the cable box...


Hello

Your TV will display all High Definition signals as 1080i True HDTV™ and all standard definition signals will be displayed as 480p.

Component Inputs 1-2
YPbPr(480i/480p/1080i)
These inputs can be used for the connection of A/V equipment with component video outputs, such as a DVD player or external HDTV receiver. Please see Appendix B for signal compatibility.
Input DTV (480i/480p/1080i)
This input is used to connect an external DTV receiver, and can be configured for YPrPb and RGB plus H&V signal types.

As a special feature, you have the ability to adjust the red and blue light beams in reference to the fixed green light beam. This process is called convergence. There are two separate memories for convergence. One, for SD 480i/480p signals; the other for HD 1080i signals. SD convergence should be adjusted while watching an SD source and HD convergence should be adjusted while watching an HD source.

Wide Expand: Enlarges the picture, cropping some of the image on both sides. This Expand format is useful to remove or reduce black side bars on HD broadcasts of 4:3 images with black bars. Available for analog 1080i, digital SD 16:9 and digital HD signals.

InputDTV
This input is compatible with most standard DTV and satellite receivers with component video (YPbPr) outputs. Compatible DTV signals are SDTV 480i/480p, and HDTV 1080i. All other DTV signals, such as 720p, need to be converted by the DTV receiver to one of the compatible signal types. Please check the DTV receiver specifications before connecting.
This input is compatible with some DTV receivers using RGB with "separate H and V sync". Compatible DTV signals are SDTV 480i, 480p, and HDTV 1080i. All other DTV signals, such as 720p, need to be converted by the DTV receiver to one of the compatible signal types. Industry standards for DTV RGB signals (systems, synchronization, timing, and signal strengths) are not currently established. These inputs will not be compatible with all DTV receivers that offer RGB, HV outputs. RGB, HV signals with less than 5 cables are not compatible.
If your DTV receiver offers both DTV component video signals and DTV RGB, HV signals, we suggest you use the DTV component video signals. Check the DTV receiver specifications before connecting.
Ok.

HD TV - Comcast - Samsung TV - "Component 3 not supported mode"


Hello willardlang,

This is because of the type of Component Video being used. Let me explain We got so use to the term RGB to explain component video we for got that there are two standards for component video and they are not compatible. These two standards are Component Analog Video (Y, R-Y, B-Y) and Component Digital Video (Y/Pb/Pr) or (Y/Cb/Cr)

Now, the problem is they never told us the public which one to use and when, they only told us RGB. Now to complicate things, you have have to figure out which one to use. So here is a helpful yet flawed hint:
If the TV was made after 2003 use Component Digital Video (Y/Pb/Pr) or (Y/Cb/Cr)
If the TV was made before 2003 use Component Analog Video (Y, R-Y, B-Y)

Yes this is flawed but for the most part it's good.

I hope this helps,

Thank you,

Just bought TV and connected with red,white, yellow and s-video connections. screen says NO SIGNAL. I have a satellite dish and dvd/vcr. the dvd/vcr image shows up on tv screen.


* Possible Problem *
It's not clear how you have each of the components connected to the TV, but you do mention that you used the "yellow" and s-video connections. Those are both video connections. The yellow is a "composite video" connection. Many TVs won't accept signals from both the yellow and the s-video connections at the same time. Usually one will override the other.

* Possible Solution *
Make sure the satellite dish is on and (hopefully) on a valid channel. Try disconnecting the s-video and checking the screen. If it didn't work, remove the yellow connection and replace the s-video cable. Check again.

If the problem persists, please explain how the TV, dish and the dvd/vcr devices are connected to each other (audio cables not relevant).

Poor picture quality on my samsung HD TV


Hey xf1racer,

Based on the description that you provided, it sounds like you are using a bundled composite video cable to connect your cable box and TV. Composite video cables generally consist of three color-coded cables: one yellow, one red and one white. While the yellow cable is typically used to transmit the video signal to your TV, the red and white cables transmit the right and left audio channels respectively.

Red/green/blue bundled cables however, are often referred to as component video cables - each of the three colored cables is used to transmit a different portion of the same video image from one device to another, and require a second separate cable (typically red/white) to transmit an audio signal.

The primary benefit of using component over composite cabling is that many users may report a cleaner, more brilliant image on their TV as a result. Please keep in mind however that this is not a guarantee that changing from your current set-up to component cables will improve the picture quality on your TV, as picture quality is often based as much on personal preference as it is the actual configuration and settings of the equipment used.

Additionally, many retailers may suggest changing your current configuration to one using HDMI cables instead to improve picture quality even further. Unlike composite and component cables, standard coaxial cables, and S-Video cables which transmit analog signals, HDMI cables are designed to instead transmit uncompressed digital signals. This typically means that more information is available for your TV to process in terms of color hue, color intensity, as well as image resolution. Again, remember that any perceived improvements will be based on both personal preference as well as your home theater configuration.

Should you have any questions or lingering doubts, I would strongly suggest speaking with a Magnolia Home Theater agent at your local Best Buy™ store for more information. Most stores will have similar TV's on display using more than one type of connection, and sales associates are always able to provide additional suggestions if desired.

Hope this helps you out.

Sincerely,
Aaron
Go Ahead. Use Us.

When the screen goes blank, hit any remote function that will show up on the screen-like volume bar. If the display is missing as well, then you have a tv problem. If the volume display is there when the tv picture is not, you may require a software upgrade.
