I thought we open up a dialog and try to answer some of the most common questions rear projection TV users are experiencing… whether they have a DLP, LCOS, D-ILA, projection LCD, it’s really all the same technology more or less.

I’ll update this frequently, but please send your questions and answers and let’s compile a list to help everyone out!

Questions like:

  • My TV is making a weird noise, what can be the problem?
  • The front LED lights are blinking on my TV, what is the problem?
  • There is a loud humming noise coming from my TV…
  • TV shuts off automatically. It’s gotten worse over the last couple of weeks…
  • None of the buttons work on the front of my TV or the remote control doesn’t work…
  • I get audio but no video…

      Hi Steven,
      This sounds like it may be a problem with a cable connecting to the T-Con board. If it’s not connecting properly or has become loose it may be causing that white haze. I would suggest joining our forum where there are experts who know that me to help you out.
