I recently ordered cable, tried to set it up via HDTV cables and I get picture but it has a streaming red and green line that goes up the screen constantly.. I hook up my xbox to the exact same ports and I get perfect picture. I have tried changing cables and cable boxes. I cannot figure it out.

More info would be nice. Are you using HDMI or Component cables. If it is component cables (red, blue, green for video white and red for audio) Check your red and blue connection. Green alone will give you a black and white picture.
If you are using an HDMI cable, replace the cable to see if this changes anything or if you have another tv swap cables to see if problem stays with tv or moves to another tv.

meder tv service......this can sometimes be due to t-controller board failingnot sending proper data to panel.....can order on shopjimmy.com or partstore.com....happy repairs....

Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

in order to send hd video to your HDTV, you will need to use a hdmi cable. If you are planning to use component cables make sure you have component output from camcorder..still it is not HD.

The panel might be broken, but you should check the LVDS cable inside the TV:

any verticle bar which is blue, red green about an inch wide can be fixed by replacing a control board in the set. Board number 6871QCH038C. Can be ordered through Parts Store.com for about 112.00....easy to install yourself, located behind two larger boards which are ribboned together. Takes about an hour.

Ur convergence is dead.Require convergence kit tv model,replace parts.

Insignia and Geek squad has no other solution exvcept 1080i

The green, black and beige cable is non-standard and proprietary meaning that Coby has defined their purpose which hopefully is described in your user guide. It would be worth a few dollars to buy the properly color-coded cables to uncomplicate your setup. Buy cables (or cable sets) that have the same color coding as your TV jacks along with the cable suggested below.
There are several ways to connect to an HDTV system and these are normally standard as previously described.
The red and white are for right and left channels and it isn't uncommon to see a three cnductor cable with one not connected since one of the methods of connection is to supply audio via two cables, video (composite) via a 3rd which is plugged into a corresponding jack, normally colored yellow. Audio cables aren't really required to carry the mix of much higher frequencies of composite video.
If you have the following connectors, try this:
- S-Video (this does not contain any audio information and requires an S-Video cable) - Right (red) and left (white) audio paths.    The S-Video connection provides a better signal that gives you a noticeably sharper picture. This setup is selected from the TV's input source menu.   

more then likely you are using component input if you are check to make shore they are hooked up correctly red to red green to green and blue to blue if they are you might have a bad cable I have not seen a color stream board bad yet
