New Tv Flashing Off/purple When Lights Turned Off


Recommended Posts

Hey guys

It seems like my place got struck by lightning or something during the week.

Came home to my circuit breaker tripped and my Panasonic plasma not turning on. A bunch of electronics in the place are also fried. Electrician came out and thought it was a strike/surge and that everything (minus the wrecked electronics, i.e. washing machine, foxtel, playstations) was okay.

So I got delivered my new Sony KD65X8500B during the day and tonight we've noticed that when certain lights are turned off around the house the tv flicks to black, and in rarer cases, to purple. I'm going to do some more thorough testing tomorrow with sources/cables etc, but I'm thinking it's the house as opposed to the tv.

Any thoughts or advice?

Thanks

Some while ago I installed 12V LED downlights and these caused severe reception problems i.e.pixelation, colour changes and ,at times, complete loss of picture and sound. Digital radio reception also suffered however FM was not affected to any great extent. Your problem appears to be quite opposite causing problems when there are no lights or do you just dim them?

Hey hornblower, thanks for your quick reply.

It actually only seems to happen when i turn off certain ceiling lights in the house, a mix of conventional incandescent and down lights. I actually thought all the lights in the house were on the same circuit, and separate to actual appliance powerpoint circuits... so maybe it is some kind of interference?

Compact fluorescent lights on dimmer circuits are the most regular offenders for this sort of interference. Even if the CFL is designed for use on a dimmer circuit they can be an issue.

Thanks for taking the time to reply guys.

I have no idea how, or why, but I have identified that the issue occurs due to one new HDMI cable. I take it out of the equation and the house lights do nothing. I put it back and turning the lights off causes the tv to flick off... bizarre!

I've got a replacement HDMI cable and a new surge protector.

Cheers

      A pull-out-all-the-stops performer with future-proofing to its name
      Pros:Fantastic picture all-round, HDR support, Native 4K, Future-proofed, Solid, attractive design
      Cons:No 3D glasses, A pricey option

      Pros:4K pictures look amazing; HDR pictures look even more amazing; good setup flexibility; good price for what’s on offer
      Stuff TV
      A future-proofed projector with a license to thrill
      Pros:Startlingly good picture all-round, HDR and 4K, Dead simple set-up
      Cons:No 3D glasses, Still a pricey option

      HI
       
      I am getting a 75" Sony Bravia XH95 installed this afternoon.
       
      Searched the net and have only found a couple of posts on how to set it up for the best picture settings.
       
      I know "best" is subjective and personal preference however does anyone have a good starting point guide or recommendations?
       
      Cheers
