Extractor light interference with TV

When I turn the light on for the extractor fan above the cooker (Autosleeper Broadway fb) , the signal to the TV fails. The TV booster is nearby in the wardrobe next to the cooker. Took it to Marquis who said there was a problem with the booster. They then fitted a new booster. Took the vehicle home yesterday,  tried the TV, and guess what,  same problem.  Anyone else had this issue.

If the extractor fan has LED lamps then it’s possible that this is the cause of TV interference. Poor quality LEDs are known to be a potential problem in this way and I seem to recall has been reported previously on here. Recommend you replace the lamps with Philips or Osram LEDs.

Ok, I'll have a look at the LEDs, thanks.
