720p 50 inch LG plasm TV....all HDMI ports are now dead.

ukiltmybrutha 301 February 22, 2016 at 04:44 PM
I physically broke 2 out of 3 ports on this TV when I opened it up to fix another issue. Long story....

Anyways, there was one HDMI port left on the TV. I purchased an HDMI switch for that hub that allowed me to connect multiple devices and switch devices manually.

Well I recently left my WDTV and XBOX 360 on and plugged in simultaneously. In the morning the TV now produces an extremely dim picture on that HDMI port.

I know it is the HDMI port because one of the other HDMI port on the TV is barely useable (but will give you a complete and bright picture) if you hold it at the right angle. (The shield on that port is mechanically damaged making it extremely unreliable).

All I have left are 2 free component jack sets on the TV and 2 composite sets on the TV.

The TV is now about 7 years old, but I'd still like to see what kind of mileage I can get out of it.

I have thought about hdmi to rca or composite adapters as a stopgap, but was wondering if that setup would support 720p.....I am doubting it.

Thanks for any info.

Component can support 1080p if your devices do, composite is much lower quality. If you try to use a HDMI to component adapter you will have problems with some content (hdcp). A component video cable for the xbox 360 is pretty cheap: http://www.amazon.com/Microsoft-X...B000B6MLPU

A good HDMI switch should have been able to handle multiple devices connected and turned on.

I'd consider getting a short 6-12" HDMI extension cable for the port that sometimes works. You could use something like some hot glue, sugru, or some other adhesive to hold it firmly in the position that works and support the female end of the extension reducing strain on the problematic connector.

720p @ 50" isn't that enjoyable. 720p at sizes <32" isn't as bad.

Thank you! I wouldn't know the difference at 50 inch and would rather keep it that way....lol!

The funky HDMI bit the bucket as I tried to support it.

I'll try the component cable on the XBOX 360.

What about my WDTV Live Media Player though? Would this HDCP be an issue? Not sure when and where that content would come up.

Would component audio (the L&R audio jacks that would remain) be substandard as compared to HDMI?

There are lots of moving parts to this antiquated setup, but like all Legacy garbage I am trying to keep things running as long as possible.

Also part of this setup is a Samsung 5.1 Home theater setup that would be a real hassle to remove from this setup.

It has an HDMI connection and an Optical connection. I have been running the Optical connection between the TV and the Home theater as opposed to HDMI for other reasons (basically because I couldn't get the WDTV Live to output sound other than via optical....probably a settings issue).

Thanks

A lot of content is HDCP protected. There are many things on the xbox 360, and things like netflix, hulu, etc are hdcp protected. It varies by content / content provider, but on many things you can get lower resolution analog video (composite/component) but hdcp is required to get full res digital. So it helps you that you only want 720p.

Thanks....I just picked up the XBOX 360 cable for now.

Just need to figure out how to get the WDTV to player to play on Component. Will see what happens and move the TV over to the kids next.

yes, that would only be stereo. The best you'd get out of it would be prologic.

HDMI and SPDIF (optical or coax) are about the same quality wise.

World of knowledge here. Thanks again.

Well I was able to hot glue an HDMI cable on that port which is on the edge...took your advice and lucked out!

I might JB Quick it later.

You alluded to different qualities of switches.

I was using something like this without all the fancy paint work:

http://www.ebay.com/itm/New-3-Por...xyLchRvszI

Is this possibly junk?

Is there something better out there with the same simple form factor? It's already a rats nest back there....(I guess it could have been worse had I not salvaged that HDMI port).

I like hot glue or something like sugru better because you could remove it if you need to.

The better quality hdmi switches require an external power supply. The quality of some direct from asia parts like that varies widely. Cheap stuff from ebay, dx, meritline, etc often leaves a lot to be desired. Sometimes it doesn't even function.

Here are a few examples of better hdmi switches:

Very cool, thanks for your thoughts. I thought about the JB just about the same time you did. With the weaker JB Quick variant I could get it off....but who wants to be grinding and messing things up back there.

So far so good!

It's probably a good idea to use some cable ties and cable tie mounts to help support the cable a foot or two from the jack. If necessary, you could always swap the foam adhesive for the super strong red foam adhesive tape.

Sounds like you may have a solution. If you ever need to strip off DHCP in order to run a HDMI to Component adapter try something like this:
http://www.amazon.com/gp/product/...detailpage

I use this to send video to a portable screen that does not have HDCP capabilities. Not sure if $20 is worth it though.
