Question about Initial Televison & Video

1 Answer

No signal HDMI or DVI

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?

    Have contacted service technicians in my area, but they mentioned nothing about doing a firmware update. Surely, they would know to do that before recommending that I replace the main board to solve the problem?!?

    Dear Mr. "Repair work to Electronic Equipments": Where do I find firmware update information for Initial HDTV-320 sited above? The source you referenced was not helpful. It is easy to say "Do a firmware update. Contact any service technician." recommend a source that is not provide the information I need, then leave me hanging. You claim to be a "Professional Technician since 40 years with a Pro rating". How did you manage that with such sketchy information? So far, you have not been helpful. Would you care to try again?

    And Fixya.com lists your comment as a "solution". Far from qualifying as a solution, it only adds confusion to the problem. I was very specific in describing my problem, yet you failed to address those specifics. If the solution to my problem does not require a main board replacement, but rather a "firmware update" instead, why not provide some explanation to give your so-called solution some credibility. Or are you someone who thinks he knows something and wants those of us who need help to think so, too.? So far you have not demonstrated that you know any more about the solution to my problem than I do.

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.
