Question about Mintek DTV-373-D 37 in. LCD HDTV
After a move, I recently hooked up our flat screen Sylvania TV to a Directv satellite receiver, same company but a different receiver than we previously used, and DVD/VCR unit. When playing a DVD the TV displays color, but when using the satellite the picture is in black and white and grainy.
Although the TV has inputs for S-Video, I only have composite cables (yellow, red, and white). There is no input on the TV for a coaxial-type cable.
How can I get a color picture, and improve picture quality with the TV connected to a satellite reciever and DVD/VCR unit?

Actually, it is not a Projection TV Problem. The problem is with a Mintek DTV-265 26" flat screen digital TV (not projection). I have not yet resolved the problem by unplugging the set, pressing the eject button and replugging in the set nor have I had any other suggetions. The manual clearly indicates Mintek DTV-265 26" (not Mintek DTV-263) but I feel they are very similar; however, the manual does not mention losing/restoring the on screen menu.

It may be a little different on the 26" model. It's been several months since I did the repair so my memory is a little fuzzy. It sounds like the non flat strands are a common ground and the flat ones are the hot wires. The best thing to do would be to take a multimeter and test for continuity on the center of the RCA jack and the flat strand of metal. If you get a reading, that is where the input wire should be soldered. More than likely you're correct and you should proceed as you found logical.
All you're really doing is making a new connection for the component input on the back of the TV. So just make sure that each hot wire from the DVD player will be on the strand of metal that corresponds with the hot wire from the component RCA jack, which is the center part of the jack, not the outer metal sleeve. In theory you could just attach all of the grounds from the DVD player to any metal part of the TV; I do not know if this will work however because the set might have a failsafe on the motherboard, not allowing video pass through when grounds are not detected.
I hope this helps! And please let me know if you get it working or have any other issues.

The biggest reason is the input on your TV will be stuck in DVD mode. Therefore the set expects any audio to becoming from the DVD player and not inputs on the back of the set. So every input on the back of the TV except for the component input is non functioning. Another reason is that you have no way to control the volume of the TV since there are no functioning buttons save the power button.
If you cut the speaker wire in the TV and solder to the respective RCA connections on the back or side of the TV you can treat the speakers passively, meaning there must be some sort of amplifier to power them. You could also just splice some wire to the cut speaker wire to extend the speaker connection to an amplifier, but I'm not a fan of loose wires coming from the back of my TV.
Therefore, using this set up you would have your cable box attached to your TV and an amplifier of some sort, and the amplifier attached to the RCA connections you soldered for the speakers.
Here's an amplifier that would work for fifty bucks:
To turn the TV on just make sure the power button is pressed (this will put the TV in standby) and then press any other button on the side of the TV: Source, volume, any of them will work.
In order for your cable box's remote to work it will need to be programmed for the TV. I have been unable to find the program codes for the TV, but I do know that Comcast's cable remote will work if you do the code search. You do need to reconnect all the grounds that you disconnected as well.
Let me know if you run into anything else

Check if the remote is in TV position, that is, because most of the remote controllers have the feature that you can program them for use with another devices. Make shure that one button that says "TV" in pressed and released once before you try to change any function on the TV.
