Question about Initial HDTV-320 32 in. LCD TV

1 Answer

No signal for HDMI or DVI

Have a new (never been used) Initial LCD TV Model HDTV-320 with all functions working EXCEPT no signal for HDMI or DVI. Vision inspection of main board reveals no obvious problem with ports. Main board is a DTV3218ATM V2.3 QAM. Assuming I need to replace the main board, where do I get one?

    Connected Netgear NeoTV Streaming Player through HDMI port and connected MacBook Pro laptop through DVI port. Both devices worked on smaller Sanyo flatscreen TV using the same HDMI and DVI cables.

Hi, what device or devices have you tried to connect through those ports? Were they working prior to this problem?

    I would assume then this new TV is the issue. I had this issue on a TV in a holiday cottage. Turned out they were dummy/redundant ports for higher end models of the same TV. Is this a feature the new TV supports?

  • Gary Sampson

    Yes, these are features the new TV supports according to the manual. Following is a more detailed account of my problem. I have a like-new (never been used) 2007 Initial LCD TV Model HDTV-320. All functions work EXCEPT no signal for HDMI or DVI. I have connected a Netgear NeoTV Streaming Player through HDMI port, but get no signal. Also, I have connected a MacBook Pro laptop through DVI port, but get no signal. Both devices worked on a smaller Sanyo flatscreen TV using the same HDMI and DVI cables. So I know both devices and cables work. A cable company tech suggested the ports were bad, so I removed the main board. Visual inspection of the main board revealed nothing obvious, so I showed it to local electronic technicians, who said they were unable to test or repair the main board, but they suspected that is where the problem lies. Main board part number is DTV3218ATM V2.3 QAM. A Google search for this part number suggests this same main board is also used in another brand, ILO LCD TV Model HDTV-322. Further research revealed the ILO and Initial brands look identical. If you agree the problem most likely originates with the main board, can you recommend a reliable source for a replacement? Should I search for new or used? How much should I expect to pay? Based on the information I have provided, can you think of another possible solution to the problem? A "firmware update" was suggested, but I have not been able to find firmware update information for the Initial HDTV-320. Any suggestions on this?

    Yes, I would agree, with information you have provided a mainboard replacement seems like your best bet. I can't recommend anyone to supply this part, however I can advise most manufacturers, if you approach them directly can advise you of their main part distributors.

    My first action was to contact manufacturer directly on 3-17-14. So far, no returned phone call or reply to email. NO HELP from Double Power Technology (formerly Initial Technology, Inc.), 1935 Puddingstone Dr., La Verne CA 91750 U.S.A., 800-216-5156 or 909-974-2859, www.doublepowertech.com. Why is it so difficult to find main part distributors for brand TVs? Since I have the main board part number, would you recommend that I take my chances on finding a replacement part on Ebay? And by the way, you did not comment on the "update firmware" theory that I mentioned. Could my problem be solved with a "reset"? And where do I find the firmware update information? Sorry for all the questions, but you guys are the only ones providing credible responses to my inquiry. Thanks!

SOURCE: can't get all digital channels

There are several possibilities assuming you have an outdoor antenna with the amplification. You are too far from the transmitter or the station is still on a low power digital transmitter until the analog broadcasts end. Additionally, there may be buildings, hills or trees in the way. The first one is called the digital cliff - you either have enough signal for your tuner or you don't. Some stations may need to add transmitters to cover the secondary areas that could still receive the analog signal. The second possibility will either resolve on Feb 18 or June 12 or anywhere in between. (It will depend on your station and the Digital TV transistion delay bill. Some stations are changing frequencies with the transistion and can't go to full power until another analog station moves its frequency.) The last one can't be resolved.
If you have an indoor antenna, you can try moving it around to get better results. My household has an amplified outdoor antenna with a rotator to get the antenna to line up with the signal. We have two analog stations that give problems when we look for their digital signals. We hope the issue will resolve with the changeover since we have seen the signals on both stations improve when they wanted to broadcast football games.

SOURCE: initial hdmi tv, no signal received

If you are trying to get 'off the air' signals then you must scan for the new digital channels in your reception area (this info should be in your owners manual). If scanning doesn't find any signals, you might have to add a VHF/UHF line amplifier(s) between your antenna and the TV set or improve your outside antenna or the cable leading from it to your set. You might have to resort to subscribing to HD cable or satellite TV.

How do I connect my PS3 to my sanyo dp50747 in hdmi? I have everything hooked up correctly, but its not coming up on the TV. What do I do?????


If you see a no signal message, then it means that the signal output format of the PS3 does not match . It happens if you have previous used it on another tv and now connected it to a different tv. To resolve this, turn off the PS3 . Press and hold the power button on the PS3 till you hear three BEEPS. The PS3 should automatically detect the tv's resolution and the initial setup screen should appear. After that you should just follow on-screen instructions to set it up.

How to connect a Samsung R700 PC to Sony LCD TV KDL-46S2010


hi my name is Rui i would like to help you with your problem...

its just easy to connect a PC to a sony lcd tv...^_^ here are 5 ways to do it...

1. S-Video - This is probably the most common method out there currently because an S-Video Cable is cheap as heck and just about every TV under the sun has a S-Video port. You'll have to make sure you laptop is equipped with this port. Remember, there are two types of S-Video cables: 4-pin and 7-pin. Most laptops and PC's are equipped with a 7-pin port, so if your TV only has a 4-pin S-Video port, then this method will not work.

2. VGA - If you have a HDTV, then you will be better off connecting using a VGA Cable. It gives much better quality than S-Video and as with S-Video, the cable is very cheap. You usually won't find a VGA port on regular TV's though, so this option is if you have an HDTV.

3. DVI - DVI stands for Digital Visual Interface with "digital" being the key word there. The digital signal will give a higher quality picture than either S-Video or VGA. Of course, your computer will need to have a DVI connection and your TV will need to be an HDTV. This cord is definitely not cheap, it ranges anywhere from $40 to $80.

4. HDMI - Using HDMI will give you the best quality by far. No computers that I know of yet have HDMI ports, but you can get a DVI to HDMI cable to connect it to your HDTV. HDMI is compatible with DVI.

5. Scan Coverter Box - This is the last method that I could think of and it involves using a scan converter box, which takes a VGA signal and converts it into S-Video or component video.

just try hooking up 1 of this tips i give you.well if you ask me i prefer HDMI & VGA. ^_^
but it will still depend on your preference..

hope this will help you... Good luck... ^_^

How do I connect my hdtv cable box to the tv/monitor. There is no hdmi input on the tv.


Your setup has a TV/Monitor and a audio/video box. The A/V box is connected to the TV and other source inputs connect to the A/V box. Hookup your cable box to the A/V box either using component video (green, blue, red) RCA cables from cable box outputs to the A/V box inputs OR the A/V box also has a DVI/HDMI input jack which may work using a HDMI cable.
Select the proper source.

I have a Samsung Series 6-650 LCD TV (Model # LN46A650A1F). I am trying to connect my Laptop to use the TV as a monitor and have done everything to make it work, using a VGA/HDMI cable, but the TV refuses...


Why do you use VGA-HDMI cable? This TV works fine with VGA cable - it has VGA plug.
Or if your notebook has DVI output, then you can use DVI/HDMI cable and connect it to the TV to plug named DVI/HDMI (only one HDMI input is marked as DVI on TV).
I suppose that over HDMI the TV supports only some standard resolutions, but over VGA it supports almost every resolution laptops use. You can find supported resolutions for each input in the TV manual. Try setting the same resolution on the laptop.

What do I need to hook it up to an hdtv...what type of cables..DVI-D to HDMI?


Your laptop will need a HDMI output or a DVI output for HD video. If your laptop only has a VGA out the your tv will need a VGA or DVI input. You could use a vga to dvi adapter if your tv does not have a vga connector. They do have a DVI to HDMI adapter but there are a couple of problems with that. One you will not get the sound and the TV will only obtain sound from HDMI cable when connected that way and Two the TV will have problems processing the signal from the computer due to the HDMI will only process the HD signals at certain formats and the computer video can send out many different signals. I tried and I could not get my tv to process the signal so I got a video card that has a HDMI out and my blu-ray player works great.

yes the DVD player will work on it thru HDMI to DVI connector but however the audio is not carried on DVI so you will have to have a seperate audio cables. also the 1080p signal is not supported by this set 1080i only.
