IÂ´m experiencing a problem that may be RF interference, but IÂ´m not sure yet. I first noticed the problem while watching the Delos â€œDVD Spectacularâ€: at the â€œ1812 Overtureâ€, I noticed that, on the â€œcrescendosâ€, it was clearly visible something like a spot, or phantom image, or dark flame (I canÂ´t describe exactly), moving vertically along the centre of the TV screen, from bottom to top. Also noticed the same problem with the â€œTrue Northâ€ DVD (Miramar), which combines extremely calm images with strong electronic music. I repeat, the phenomenon is only visible at the louder musical passages, and with the volume knob cranked up. Turn the volume down and the phenomenon disappears.
First I thought it had something to do with overcharge on the AC circuit, plugged the TV in another separate circuit and nothing changed.
Then I thought it was the DVD Player, borrowed one from a friend and the problem remained. By the way, also noticed the problem while listening to loud music through the CD Player with the TV turned on (and thereÂ´s no any connection between my CD player and the TV).
The DVD player is connected directly to the TV with S-video cable, so the video signal doesnÂ´t pass through the audio system (also replaced the S-video cable and nothing changed).
My current system includes Adcom GTP-550 preamp/processor and Rotel power amplifiers. Borrowed a preamp from a friend and, again, the problem remained.
Interconnects are Tributaries, XLO/VDO, AudioQuest and Monster Cable.
If you can, please help me to solve this problem.
Thanks in advance.
Demetrio.
