50 foot HDMI cutting out

sman1234 · 12-31-2012, 09:31 AM

Hello all, hoping someone can help me out. I am having issues with a 50 foot HDMI cable that I recently purchased. I have it connected to the TV and when I turn on the blue ray player, the thing will work for a second or two, but then the screen will go black and then say “ no signal”. It does the same thing when hooked up to the cable box ( picture will be displayed on TV for a second or two then nothing). Then, if I hook the tv up via a 25 foot cable it will work fine ( both blueray and cable). I would think that if the 50 foot cable was defective, it would just not work at all ( rather than work for a second and then go black) What am I missing here????

It may be a bad cable. Go to monoprice and they have an adaptor to make a ethernet wire HDMI for long runs with no loss.

Welcome to the forum. What is probably happening is the voltage loss over 50 feet is right on the threshold for your TV to work. So sometimes it works and sometimes it does not. I think monoprice also makes a HDMI amplifier as well as the cat5 cable adapters.

Being that you already have the 50 foot cable, I would follow rbinck's recommendation and get an HDMI extender to try first. It's very likely that will solve the problem. I have a 75 foot HDMI run and it works great with an extender at the sending end, but fails without one.

I would recommend powering the extender (external 5V supply).

If you have a couple of devices to send over the HDMI cable, you might consider an HDMI selector (2x1 switch) with extender built in. This will allow you to select which device you want to send to your display, and work with a longer cable as in your case.

50 feet is the maximum to push the signal. If your signal is slightly low to start with, it probsbly isn't making it the 50 feet.
