Soldering resistors to AV cables and to HDMI cables

I have 3 LG TVs. Each has the same problem of randomly displaying an message about an AV input on one, and HDMI input on the other two. This is a common problem with all types of LG TVs, based on my Google search for a solution. On one thread, a poster stated he had a solution: "Any number of LG TVs have this issue. The solution is the put a load (~1000 Ohm) on each of the three analog AV inputs. Get a set of component AV cables. Cut the cables approx 6" from the RCA jack, strip the leads (there are two). Solder a 1000 ohm resister between the positive and negative lead on each of the three cables. This will fix the issue 100%." See, [login to view URL] MY PROJECT IS--soldering to the end of an AV cable (that will be attached to a TV input) a load (~1000 Ohm); and to do the same thing for the cable that will be attached to the analog AV input of a TV. .
