Question about Mintek DTV-263 26 in. LCD Television

1 Answer

Mintek Fix Ryan, Why can't I accomplish this by just plugging in the two audio wires from the RCA composite cable into the jacks on the set? What is different about soldering in the connections as you described as opposed to just plugging in the red & white audio jacks? What can I use as an inexpensive amplifier or receiver to power the speakers. I don't want to spend a lot of money for this purpose? I know you suggested the Onkyo but that is a couple hundred $$. Can you suggest some other cheaper source to power the speakers. Also how do I turn on the TV itself after I make the cable connection to my HD cable box? Will it come on as soon as I plug it in or will I have to use the on/off switch on the side of the unit. I don't have a remote for the TV. Can I plug the set into the rear of my cable box so that I can turn it or with the cable box's remote which is how I have it setup with my other TV. In either case will I have to reconnect the plastic interconnect and spade ground that comes from the on/off and other control buttons on the side of the unit? Mike

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

How can I connect a WII console to my Champion Plasma CV 142 TV set? Can I connect it with RCA cables?


The 42CVI has both composite and component video in the standard configuration. Either of these should connect to your Wii console. You will get better results if you use component video (3 RCA plugs on each end of the wire for video (Y,Pb,Pr); use a second cable with two RCA plugs on each end for audio.) The Component video is Input-4. The component video cable is usually not provided with the game console. There are 2 composite video inputs on the TV (these use one wire with 3 RCA plugs on each end of the cable for video (yellow) and audio (red and white)).

I hope this helps.

When I plug my PS2 or VCR into the back of my TV using red, white (audio), and yellow (Video) cables, the picture is grey and fuzzy. I have plugged the yellow into the far left port marked "Y". I...


Yellow is a composite output and should be plugged into a composite input, whereas Y indicates the COMPONENT input of the TV. If you don't have a separate composite input use a scart to phono (rca) adapter in your tv's scart input.

I hope I have been of help but please do not hesitate to ask if you have any further questions.

We need to connect a wii and a dvd player up to our 32 in Emerson? Unsure of which jacks to use?


First, you must figure out If your TV has component video inputs. This is a set of five cables (red, blue and green for video and red and white for audio) and will give you the best picture on an hdtv


Then, If your TV does not have the component video cables, you will be using the red white and yellow composite yellows the system came with. A very simple connection.


Last, If your TV does have the component video inputs, you will need to buy a set of the Nintendo Wii Component Video cables from Walmart, Target or any other gaming store. These will enable widescreen view and the best picture quality.


To connect your DVD player, you need to located the composite video inputs and s-video. Composite video is a yellow, female RCA jack, normally found next to two audio jacks, one red, the other white. The three jacks together provide an interface for audiovisual connections. The red RCA jack connects the right channel of a stereo system, while the white RCA jack connects the left. The yellow composite video jack rounds out the set.


When playing the Wii, you will need to be on the correct video input "Component"


When playing the DVD, you will be on "Composite/Svideo."

Hi, I bought an aquos lc-30hv4u and it has no rca jack etc, only two plug ins labled display input 1 and 2. I am guessing its just a pc monitor. How would I use it for cable tv video games etc


There are lots of inputs on the back behind the cover. Three inputs (1, 2, 3) have an S-video, composite video (A/V) and component video jacks. The cover will come off if you press the two top hook at the top of the cover. Then rotate the cover towards you. There are also a DVI-D port and 2 coax (antenna in) jack. The tuners included are for NTSC (analog OTA) and CATV (analog cable). The front of the PC (VGA) and a S-video or composite (A/V) video input (called Input 4).

Composite and component video jacks are all RCA jacks (as are the associated audio jacks for the input). Composite cables uses three RCA plugs on each end - yellow for video, red and white for Right and Left audio. Component video cables have three plugs on each end that just carry video (red, blue and green); the audio is wired separately with just 2 RCA red/white plugs. Match your colors from the device out to the TV input.

Changing inputs can be done with the remote or the input button on the top of the TV. The input button is to the left of the power and Main Power buttons.

Connecting your game system, cable system and all will depend on the units. For the best picture, use component video cables for mose set top box. Some cable boxes have a DVI port - use that if the box has that option. If they do not have component video out, then use composite or S-video cables.

The owner's manual is available from Sharp as a pdf: http://www.sharpusa.com/CustomerSupport/ProductDownloads.aspx?downloadtype=ownersmanual . Use the drop down menus as follows > LCD TV, Model not listed, LC-30HV4U then click Search. The picture of the inputs are on page 10.

I hope this helps.

THERE ARE 3 WIRES YELLOW,WHITE, AND RED WHICH WIRE I CAN DO PROPER CONECTION for get DVD WHICH JUCKS I CAN PLUG?


OK, what you have is the Composite Video cable (Yellow RCA plug) and the Audio cable for Right (Red RCA plug)) and Left (White RCA plug) audio channels. You just have to look at the back of the DVD and locate the Composite VIDEO output jack and Audio output jacks, just match the colors. Sma thing on the TV, just look for either AV1 or 2 Composite Video input jack and audio input jacks.
Set the TV to select the video source you have the cable plugged into, and that is.

Plug for pc speakers wire


To use the speakers on the TV when you connect to a PC, get a 3.5 mm M/M audio cable (it may be called a patch cable or audio aux cable) and connect it to the PC audio in port to the left of the composite A/V ports (that's the group with 3 RCA jacks yellow (video)/red(R audio)/white (L audio)). The other end goes into the computer's line out (speaker out) port - which is generally colored green. Otherwise your regular computer speakers will play the audio.

If you want the TV's audio to output to external speakers, use the headphone jack (sometimes labels Phones, again a 3.5 mm plug) or a set of speakers/receiver that takes an optical audio connection. The optical audio jack is between the two coax connectors. Please note using the headphone jack will force the internal speakers off.

I hope this helps.

No problem. What I was suggesting you could do with the speakers is to splice the positive (it should be red or white) speaker wire to the hot part another separate RCA (I used the side input) jack and the ground to the jack's ground sleeve (the outer part). So the process is similar to what you're already doing with the component RCAs and wires. Once this is done you can hook a receiver up to the built in speakers in the TV with no hassle. The speakers will not be powered, however, so you can't just hook the audio output from your cable box to the TV. All this process allows you to do is hook a powered amp or receiver to the speakers.

What I meant by saying to make sure there are no grounds was to double check and make sure each bit solder did not bridge over to another strand of metal or the metal chassis of the TV and cause a short or a ground.

Anything else, just let me know.

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.

Hook up dvd to Konka tv


Keep in mind that there is only one set of RCA (or composite) inputs to this tv. For the video, you have the option of using the RCA jacks OR S Video input. When using the composite set of inputs you are using set of jacks (looking from the back) to the right of the tv that are furthest away from you. The audio for this set of jacks are the second and third composite jacks (counting from the right).
