Two things to look at first:

Remove and inspect lamp to see if damaged or if picture is dim.

Second is listen for a fan like or high pitched sound or even a grinding sound---color wheel...

Those are the two most common issues here.

Possibly a bad light tunnel assembly if the part is only a shadow effect. If not then probably a bad DMD board. The DMD board is part of the light engine but needs to be replaced by a technician.

Replaced lamp, however 50% of screen continues to turn black when the TV is on a long time.


This problems it is not fixable or worth fixing because of the CRT picture tube of screen itself.Slowly dying,now the tv it is not worth a whole tv anymore if tv require a new CRT picture tube.CRT picture tube,if u can get a hold of it,most likely only can buy it from the tvs corporations themselves only and they charges u like a new tv,because the CRT picture screen it self 90% important to the tv functions itself.

As soon as I turn the TV on, a loud screeching noise comes out, and the picture is all distorted.


It sounds like the color wheel has failed and needs to be replaced. You can call 1-800-samsung to find the nearest service center.

Color wheel for Samsung HLR5688WX DLP TV


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.

That humming sound is a sign that your color wheel is becoming or already is defective. If you don't replace it you might even lose picture in the future since it's part of the light engine system

Sounds like one of the Bulbs has burnt out. This is a very easy problem to fix. You just have to remove the back panel of the TV and replace the bulb on the side that has gone black.

The bulbs can be purchased directly from the dealer. (And are rather pricey)

BEFORE purchasing the bulb...I would first make sure that the current bulb has not become loose. Try reseeding the bulb and see if it will function correctly.
