TV woes (dead HDMI)
« on: January 22, 2017, 12:18:53 AM »
The large Vizio TV that came with my rig has 2 dead/dying HDMI ports (already! - I've only used it for a year and a half), and that's how I connect my laptop for streaming TV. (And yes, I did buy a new cable to check.)

Don't know what to do now. It's on a reticulating arm and I'm not even sure how to get it off there, or whether there are places that will fix the ports for a reasonable sum if I did?

I maybe have one alternative, which I'm running by you all for opinions. There is an RGB port with a corresponding "PC audio in" port on this TV, and my laptop is so old that it also has an RGB port. If I bought an RGB cable and the audio cable, would this be an acceptable substitute for the HDMI connection?

It will work if your computer has a serial monitor port.  That's the setup I had in both the RV and the S/B house until my laptop died and the new one I got didn't have a serial port.
Too bad you didn't post this a few weeks ago.  I just threw out a combo cable(had both the serial cable and the audio cable in one)as we were clearing stuff out of the house to put it on the market.
I believe I got both of my cables on Ebay fairly cheaply.

As far as removing the TV from the mount.  I've just changed out both the TV's in our new to us coach and thus spent some time studying mounts.
Most of them I looked at had a plate that attaches to the back of the TV with 4 screws.  This plate then hooks over the end of the arm and has one or 2 screws to lock it to the arm.  You can remove those screws(on the one I had with 2, the top one only had to be loosened)and lift the TV with the mount plate off of the bracket. 
Most of the newer flat screens are pretty light, compared to that old 23" console I drug from place to place for 20 years.

I would try yet another HDMI cable. The cheaper ones are notoriously bad.
I would like to apologize to anyone I have not yet offended. Please be patient and I will get to you shortly.

Contact Vizio. It may be out of warrantee but they can guide you in service possibilities.
Unless rig builder did something special/weird there are four screws (standard VESA) holding your articulated mount to the back of the TV...they simply unscrew.

Sure. And if your laptop lacks a PC audio jack, it will use its own internal speakers instead of the tv speakers.

Both ports dying at the same time should be rare.

Did you plug and unplug the cable to both ports on a regular bases?

Is there anyone around you that you could borrow a HDMI cable from just to rule out the new one
is or isn't bad?  Usually the thicker the cable the better the cable.

You asked if the RGB cable setup would work and the answer is YES
However HDMI is HIGH DEF and capable of 1080 resolution where as the RGB is more like 480.
So most people can tell a big difference and you may not like the results of a RGB setup.  I know I wouldn't.

Naw, I know this one's good because I had a signal... for about 10 seconds, until I moved the TV. That's the same symptoms I've been having.  :(

You're right! That would have been nice. I did order one off Amazon for $9. Will be here Tues with Prime.

FWIW, I discovered that not having a serial port on your laptop/computer isn't an issue any more. On Amazon I found a dongle that will convert an HDMI port to a serial one! Who knew?

Not from what I saw on YouTube. They probably go to the same chip inside the TV.

Oh. Crap. You're likely right, then.  :(

Funny it never occurred to me to contact Vizio! I will likely do that, too. Thanks.

As someone living in the 21st century  ;D I just want to add that physically connecting a laptop to a TV was lapped a while ago by buying a Chromecast (or similar) device and connecting both through your router instead. No more fumbling around with cables, no more balancing your laptop on your entertainment center, no more limiting yourself to one or the other but not both.

Chromecast is too simple and too cheap.

Oh, wow. Maybe I HAVE been lagging behind?

There might be one small problem with that, though. Anything going through my router costs me $$ I can't afford... unless Chromecast et. al. generates its own local signal? I get all my internet from my Jetpack/Verizon.

Chromecast, specifically, requires a internet connection (other similar devices do not), but it doesn't actually send data over it so there would be no usage charges

Guess I'll have to check this out, because I can't imagine a device which requires an internet connection but then sends no data that way.

Which "similar devices"? I would love to find a wireless solution that doesn't also suck up gigs from my modem!  :D

Rat, you say the ChromeCast requires an internet connection.  Does it require the actual internet, or will it work with just a router?
I wouldn't mind casting from my tablet or using my wireless printer for that matter.

It does not use the Internet, it just uses the Wifi to broadcast the signal. Just like a wireless printer.

If your PC has a standard 15 pin VGA connector as well as your TV, the simplest solution is to use a VGA video cable. This is an analog component video signal capable of high definition. Get one that includes a cable for audio. Here's one available on Amazon:

By default Chromecast requires an internet connection because its backgrounds and your login credentials are online, it doesn't pass any more data then that though. This helpful soul explains how to get around the issue of using it without a live internet connection:  https://www.reddit.com/r/LifeProTips/comments/38sb3v/lpt_use_chromecast_without_internetmobile_data_by/crxfse8/

As far as devices that are similar, I can't attest to either but there's Airplay and Miracast, or whatever newer product Best Buy could recommend.

Yeah, that's probably the same one I just ordered. This is going to be my next solution.

Do you have the manual for the Visio?  Try doing a hard reset.  If that doesn't work try updating the firmware.

If your current computer a Mac?  Did you update to Sierra recently?  If so the problem is probably not the TV.

Do you have any other HDMI capable devices you can connect to the TV?

I did call Vizio today and did a hard reset - no change. We went through all the most obvious possibilities (new cable; connect to another device) and even they decided it must be the TV's HDMI ports.

Now I'm trying to get repair estimates from 2 places to see whether it's cost effective to repair, while I wait for my VGA + audio cable to arrive.

Just some thoughts for future consideration...
HDMI connectors are not really designed for continuous connect/disconnect/reconnect. After you repair or replace your TV get a sacrificial extension cable for HDMI to connect to the TV and leave it connected all the time. Connect and reconnect your laptop to that to save wear and tear on the TV. Also, make sure TV and Laptop are powered off while doing so...electrical transients may have caused your failure rather than wear and tear.
Good luck!

Wish I could say that did it, but that HDMI cable was never disconnected until I started having problems and had to trouble-shoot. (And the laptop is dedicated to that TV alone and never moved, so I rarely disconnected the cable from that end, either.)

But I will take your advice seriously for any future projects that require an HDMI cable. The TV was always turned off when the cable was being disconnected, but not the laptop. Wouldn't have thought of that.

So, here's the update:

(1) The RGB (VGA) + audio cable I ordered is doing the trick! I'm perfectly satisfied with the screen resolution I'm seeing and thrilled that this was such a cheap fix. Yeah!!  ;D

(2) The repair people that Vizio referred me to no longer support my TV (it's only 3 years old!!). When I called Vizio back, they said that since they're no longer making this TV, they also don't have parts, so replacing the board that runs the HDMI ports depends entirely on whether a distributor still has it.

I guess this was my up-close-and-personal lesson in planned obsolescence? (An expensive 24" TV that's only 3 years old going straight to the dump??)

My biggest concern was that the board that ran the HDMI ports might also be the one that supported the RGB port. I am so relieved that this is not the case.

Glad it worked out for you.

I didn't know your TV was only 24" - so that is why the picture looks fine to you.
A VGA on a 42" or bigger TV wouldn't look as good, IMO  At least not as good as HDMI.

I doubt that it's worth getting it fixed at a TV repair place, even IF they did have the parts in stock.
Especially since you think it looks fine.  But you just might want to start saving for a replacement...........

Expensive 24"???????  is it 12volt?  Has a DVD built in?

It looks like the video inputs on Visio 24" TVs might be on the main board.  I.e. Not a separate board that can be easily replaced.  But without knowing the model number that's a generalization based upon a small sample of their TVs.

Probably a single chip went bad.  How are you with microsoldering SMDs?   :o

LOL!  ;D Goes to show you that I've never bought (myself) a 24" TV. Which to me is huge.

All I know are the prices I see in Costco as I rush past the gigantic TVs, but now that I think about it, those really are gigantic. I guess 24" isn't so big anymore, nor very expensive. So it really is disposable, and if/when the RGB (VGA) port dies, I'll just donate it and buy another.

CORRECTION: I just measured mine, and it's 32", not 24". But it's larger than I need, and if I need a new one, I will likely replace it with a 24".

We just got this coach in December.  The very first thing I did was replace both CRT TV's. 
For the salon, I got a 32" Element for under $150, and a 24" Samsung for the stateroom for under $100, both at WallyWorld. 
Heck the wall bracket I had to buy for the salon TV was almost more than the stateroom TV.
Only complaint I have with either TV is that none of the remote codes that Element provides will work with the Dish receiver remote.  First world problems, right?

Don't know what to do now. It's on a reticulating arm and I'm not even sure how to get it off there, or whether there are places that will fix the ports for a reasonable sum if I did?


Did you upgrade your software to Windows 10?  Have you tried using the HDMI to TV with any other device (DVD player)?
