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

Samsung's digital light projection (DLP) televisions use a spinning color wheel to create the colors that are seen on the screen. If the color wheel becomes misaligned during use, it will become damaged and have to be replaced. Replacing the color wheel on a Samsung DLP television can be done at home, once a compatible-sized color wheel has been bought from a TV supply store.Replacing the color wheel yourself will void any Samsung warranty that might be in place, but is the only solution for getting the TV working again in as short a time as possible.
Put on the anti-static grounding strap to keep static electricity from damaging the internal components of the Samsung DLP TV. Turn the Samsung around so that the back is facing you. Make sure the Samsung is unplugged from the AC socket.
2 Use the Phillips screwdriver to remove all of the screws from the back panel. Put the screws aside. Pull off the back panel.
3 Loosen the two screws from each side of the projection bulb's case. Pull the projection bulb out. Put the projection bulb aside. Use the Phillips screwdriver to remove the two screws from the left side panel. Pull the side panel and the circuit board attached to it out carefully and put it down so that the cables attached to it have not been pulled out.
4 Take a picture of the power cable's position with the digital camera so that you can put it back correctly later. Pull the power cable out from inside of the Samsung's case so that the center panel is free to be pulled out. Remove the two large headed screws from the center panel with the Phillips screwdriver. Remove the top two screws holding the panel to the plastic case using the Phillips screwdriver.
5 Slowly slide the center unit out a few inches. Take a picture of the projector lens' positioning with the digital camera so that you can put it back correctly later. Unplug the two cables from the left side of the center panel. Unscrew the sensor switch using the Phillips screwdriver. Slide the center panel completely out of the Samsung and put it down on the clean cloth. Blow off the color wheel assembly with the compressed air.
6 Use the tweezers to remove the green plug from the top of the color wheel cover. Use the tweezers to remove the two cables at the side that are coming from the color wheel. Use the Phillips jeweler's screwdriver to remove the screws from the top, front and back of the color wheel cover. Slide the color wheel cover straight up to expose the color wheel.
7 Use the Phillips screwdriver to remove the three screws holding the color wheel to the color wheel assembly. Lift the color wheel up and out of the color wheel assembly and discard it.
8 Position the replacement color wheel in the color wheel assembly. Reassemble the color wheel and reassemble the color wheel assembly. Put the color wheel assembly back into position in the rear of the Samsung DLP TV. Reassemble the Samsung DLP TV. Plug the Samsung DLP TV back in for power. Turn the Samsung on and enjoy seeing the colors displayed properly again now that you have replaced the color wheel.
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!
Most of the Analog viewing will be much poorer compared to HD. Since it it a digital product, it is designed to be used with a digital signal. You will get signal degradation if it has to take the analog and convert it to digital to be viewed and there is really nothing that can be done to compensate for it.
Hope this helps,
