So moved into a house after 3 months of remolding and started to terminate all the cables at the home distribution hub.

Well I accidentally cut one of my long HDMI runs that goes to another floor!!!

It's the RedMere 60 ft HDMI (directional) cable from MonoPrice. Re-running this would mean a lot of cutting throughout a brand new house.

Does ANYONE know of a "it was worth a shot" attempt at repairing this?

Good luck on this one, your over do. If you do not have a long enough tail on the connector to work with get a short RedMere to sacrifice, and maybe get one for just practice as this could be a one shot deal.

Ick. Does the cable move at all? If so, you can use it as a pull string to pull a new cable through. But if the replacement HDMI cable can't be pulled through due to the connector size (likely), pulling a cat6 cable and using an HDBaseT solution instead is probably your solution. If you've got any cat6 runs to that location, use that.

You did pull a cat-5/6 cable along with the HDMI cable as repeatedly recommended didn't you?

This is always a requirement IMO because HDMI will be dead in 5 or 10 (or 50) years and then the next solution will still offer some cat-x solution (most likely).

Otherwise, you are in for a real headache as I've yet to hear of a successful repair of a HDMI cable.

Yeah I ran Cat 6 through out house. I suppose that can be my backup. I'm going to try the fix phil posted to see if that works. I'll keep the thread posted to see how the project goes!!!

The Redmere cable has active components to re-equalize the signal at the TV end. The cable construction is different than a 'normal' HDMI cable. So I think your chances of success are low, but certainly nothing to lose by trying. See this app note about the Redmere solution which might give you some useful info. I just grabbed one of their notes dealing with HDMI products - the cable may have a different model chip in their product line, but the info should be valid regardless:

It's easy to match new paint color. Repairing a drywall hole (or 2) is $100 or less, from a pro drywaller/painter - cheaper than an extender over catx.

Be aware that any fix will be less than perfect, regardless of what the guy in the link said. It may yield a flawless picture today, but not work well in the future when you bump up the bit rate. A TDR will be able to pinpoint exactly where the splice was made when done by a pro, let alone a noob.

You are better off in the long run pulling a new cable or using the existing Cat 6 with an extender, preferably HDBaseT.

And if you splice incorrectly, you could damage a connected component. I've read some horror stories that are unfortunately true including smoke coming out of the HDMI connector on the component.

(Take whatever Colm tells you about HDMI to the bank)

Alright everyone. I decided to give the repair a shot. Here's the results on a 60 foot Redmere HDMI cable. took a while but It works beautifully!!!! I wrapped some shield between each one using foil and then electric tape.

I would love to see what you did to the impedance at that point in the cable. Don't suppose you have access to a TDR?

Holy !@#$ eek.gif

I think you could get away with a splice if done carefully, that is keeping the pair untwist to a half inch, use a 1/8in solder splice and keep the whole thing tight with an overall shrink boot. That would probably work for most systems.

But this? I too am very surprised it works at all over that distance.

I actually took some aluminum foil and did a ghetto shield around it with duct tape....yes duct tape. it's the most rigged cable you'd ever see, but 3 months strong now!

It was an off the top of my head idea, I had run across that post and linked it. Glad it worked out.
