Samsung hl-r5078w flickering - higher resolution is worse
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

a DLP bulb lasts about 8,000 hours (if a TV is on 10 hours a day, every
day, the bulb will last about two years). A bulb can last longer if
it's used less frequently. Typically, a bulb in a DLP TV for household
use should last at least three to four years before it starts to flicker
and needs to be replaced.
Hi,Is your tv close to 6000-8000 hrs 2-4 yrs.If its it might be time to replace the lamp.Your part # is XL2200 Make sure you get the Philips lamp.There's other components that tend to go bad like the ballast which is the board that powers the lamp.When that is bad it will make continuous clicking noises or attempts to light up the lamp.But if you dont hear any of that then most likely its just the lamp that needs to be replaced.Have a blessed one!
there is a complete section in the tv that translate the different resolutions from the different out side video sources you normally use to the TV native resolution. That area has to be replaced. Is a module repair needed. Don't get scare. now days this kind of repair is normal and has to be included in the repair price to see if is economical to repair.
this noise is an indication of a bad color wheel. aa dlp uses a mechanical motor to spin a coloered segment disk. this turn the white light of the lamp into your colors of pictures. Now anything that moves will eventally break. the flickering is also an indication of a color wheel going bad. eventally this will cause the set to shut down. Color wheels can be replaced. i dont know your model so i am not sure of the exact replacement procedure. at my shop we charge average 250 for such a repair
The unit has a defective light tunnel contained within the light engine. This part is not easily replaced and you will a qualified tech to replace it. Many service centers condemn the light engine at a much hight cost. Do not buy or let someone tell you the light engine must be replaced. This repair requires only the light tunnel.
