Just lost signal on the TV. But the light in bathroom and back bedroom. Did not effect the TV.

Kind of a very long pause between posts?

Your LEDs are causing RFI (Radio Frequency Interference) which is stronger than the TV stations strength.

The further the LEDs are away from the TV or TV antenna the less interference the TV will get.

Digital over the air (OTA) which is known as ATSC is a very fragile broadcast method. It doesn't take a lot of RFI to take out your TV reception, gets worse when you are further away from the stations broadcast towers.

You NEED to either buy a better made LED modules or buy modules without a built in voltage regulator (the ones you have was not designed properly or is missing critical RF noise reduction parts).

Typically modules with a built in switching voltage regulator will have voltage ratings from 10V-30V DC, non regulated will have a far more narrow voltage spec (10V-14V DC).

You DO need to make sure that the top voltage specified is at least 15V DC if you go with the non regulated versions, otherwise you will be burning out LED modules anytime your converter goes into bulk mode (14.4V)..

I replaced all of the 921s (16) with these cheap Chinese LEDs for about a buck a piece. We then took a 2602 mile camping trip over 21 days. No radio or TV interference. The LEDs worked great. Very satisfied with them.
