Question about Mintek DTV-263 26 in. LCD Television

1 Answer

Mintek Fix Ryan, Bad news; I completed the fix and connected the TV to my HD cable box and turned it on and I get the exact same thing I had before I fixed it. I get a nice blue screen and in the upper right corner it say "DVD" and under it says "no signal". FYI the fix I used was the one in your original email which was to solder the component cable directly to the wires of the cable coming from the DVD player. I didn't try the one where I solder the cable to the flat and non-flat strands of the component jack. I'll try that next if necessary. My cable supplier is Cablevision not Comcast and you say that the cable box remote needs to be programmed for the TV. Could this be why I don't get a picture? In the instructions with the cable box it says the TV must be tuned to channel 3 for the channels to appear. How do I get the TV to channel 3 or is that not necessary in this case? Another possibility might be that one or more of the solder connection is broken. Would one broken connection cause the fix not to work at all? Should I be able to get the code for the remote for the cable company or do I have to search for it with the remote? I not going to worry about the audio connection until i get the video working. Any further suggestions to try? Mike

Depending on the connection, one loose solder point could be the problem. Unfortunately I have to leave for work so I can't help you any further until about 10:00 tonight (EST). I will post some pictures by this time tomorrow, though. Maybe those will help as well. Oh and just to double check, you cut the wires from the DVD player and soldered them so that the component cables now run directly into the motherboard, correct?

I'll post some more info just as soon as I can.

Mintek DTV-260


The Mintek DTV-260 only has a NTSC (analog) tuner. You will need to connect your RCA antenna to a digital to analog converter box to watch TV over the air. Then connect the output of the converter box to your TV.

The common converter boxes are limited to SD output. You might be able to find an HD converter box online. (With the standard converter box, the available outputs are coaxial and composite video.) The DTV-260 has a composite video port; alternatively set the TV to channel 3 or 4 and use the coaxial (RF) input on the TV.

There may be a low-power station that still broadcasts in analog. However these are rare. You will need to switch from CATV to OTA (Air) to check for one of these stations. Analog Cable has different parameters than scanning for over the air signals.

I hope this helps.

What kind of cable do i need to connect my panasonic pc-p46c2 to a non hd cable box


The cable box will most likely have multiple options for display - the most common will be a standard coax cable(exactly the same as what comes out of your wall).

This is where I would start since you have no HD option on your cable box.

There will probably also be RCA's on the back of the cable box (red, white and yellow). You should be able to use these three, the yellow being for your video and the red/white for left/right stereo sound, to connect to your TV as well. You would need to select the appropriate input for the cable you use.

CABLE/SAT will be your coax input, and depending on the input you plug into for the RCAs it would most likely be Video1 or Video2.

You can plug in the coax as well as the RCA's without a problem, they won't conflict or anything.

Make sure the cable box is on and then use your remote to select the different inputs - there should be a specific button dedicated to switching through these.

I got a hd box and the channels keep cuttin out


Hello, I actually install HD boxes for Verizon Fios. If your video signal is too low, you will notice "Pixellation" (Those weird square boxes that come and go) and in some cases, you will not even be able to receive some channels at all. HD channels use much more bandwidth than standard definition channels. The good news....there's a fix. If you use standard cable (Not Fios) you can buy a signal booster. These can be purchased at best buy, Radio Shack, etc. It is a powered device that plugs into an outlet (110v) You take your cable company's input or "Feed" run it into the booster, connect the power, and the run a coax cable out of the booster and into your splitter. Assuming all of your cabling is up to par, this will fix your problem. If you have Verizon Fios, you must call and have us come out as our tv service uses "Moca" and cannot be boosted with a store bought unit. I hope this helps.

Screen is all Green


New cable box recently? If not, your cable provider has probably pushed a firmware update to your cable box. Green screens are very common with HDMI connection. From your symptom, I am going to take a guess that you are connected via HDMI. If so, switch to Component cables and your problem is solved. It's not the TVs fault... cable boxes seem to be the single largest problem child for HDMI compatibility. I hope this was of some assistance.

Just connected our directv hd receiver to the tv via component cables, because we just bought a blue ray player and the only output for that is HDMI and since there is only 1 DVI input we had to change the...


You may be able the settings of your directTV box to stop frustrating you. If you help me identify the model you are using, I can research the proper menu choices you will need to choose to select the correct features. There are many different directTV set-top boxes available.

My own home theater setup did the same thing, and my solution was to use component cables from the PVR instead of HDMI cables. It is too bad your blu-ray doesn't allow for this configuration.

My work-around until I realized that using different interconnects fixed the problem, was to turn the TV off and then on again whenever switching from HD to non-HD sources. This fixed my problem, maybe it will fix yours.

I hope that helps.

No sound on NON HD channels


I had the exact same problem on a brand new Insignia 26 " LCD with DVD. Comcast tech was able to fix it by changing the Comcast box diagnostics. Here is what he did. Using the Comcast remote with the TV on - press power, cable, menu in that order. A comcast diagnostic srceen will appear. Select Additional HDMI options, then audio options. Change the audio options to L-PCM. Press power again to exit the diagnostics. That will fix it and you get to use the HDMI cable.

The TV needs to remain in DVD mode. Please correct me if I'm wrong but from my understanding you're hooking the TV up through a standard coaxial cable. You'll need to connect you cable box to the TV using component RCAs, not regular coaxial cable.

Since the DVD player sends component video to the motherboard of the TV, that's the only thing you can send through the new connection you just made.

I was going to post pictures tomorrow however I loaned my sister my digital camera a few days ago and she won't be able to return it until the end of the week. I can try using my cell phone and bluetooth... I'll see how it goes.

Let me know how it goes

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

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.
