Hi,
I ordered a refurbished Samsung hlr5078w dlp tv and it flickers when displaying an HD picture mostly. It flickers less when using an S-Video connection and much worse when using HDMI or Component. So basically the higher the resolution the more flicker. The company we ordered it from said that there was a new bulb installed before the tv was shipped. Does this sound like a bad bulb or clorwheel?? or?? I'm lost.. I have unplugged the TV, Over the air HD also flickers badly.. the tv starts up pretty quick and there is no humming noise..
This problem is caused by what I beleive is a the dimming circuit. Most TV's will dim the brightness output in a dark room and brighten in a well lit room. There is a circuit that does this for you, and this circuit gets faulty after a year or so, (Bad capacitors probably) Samsung is aware of this problem and there is a fix. Just open up the back of the TV and cut jumper on the power supply (Upper right as you look from the back of the TV) named JP852 on the 46" and JP852 on the 55". If the jumper is not labelled as such. Do not cut it. To check if this fix will work for you. Go into your settings and turn picture to eco mode (economy mode) and the picture stop flickering will stay solid for about 20 mins. If this is the case.. Go ahead and cut the jumper. This procedure takes about 10 mins.. Here is a youtube video on how to do this https://www.youtube.com/watch?v=i-jQZ-TQdgU
Sounds like a damaged color wheel.
