Dark band at the top of the screen. - Mitsubishi WD-65733 65" HDTV

A 5" wide dark band in the middle of a Samsung Smart Series 7 TV screen could be caused by several issues. Here are a few potential causes and solutions:

1. Faulty LCD Panel: If the LCD panel is damaged, it may cause a dark band in the middle of the screen. Unfortunately, a damaged LCD panel usually requires a professional repair or replacement, which can be expensive.
2. Loose or Damaged Connection: A loose or damaged connection between the TV's internal components could cause a dark band on the screen. Check all of the cables and connections between the TV and any external devices to ensure they are properly connected and undamaged.
3. Picture Settings: The dark band could be caused by the TV's picture settings. Try adjusting the picture settings to see if it improves the image. For example, you could try adjusting the brightness, contrast, or sharpness.
4. Software Update: A software issue could cause a dark band on the screen. Check if there is a software update available for your TV and install it if necessary.
5. Magnetic Interference: If there is a strong magnetic field near the TV, it could cause a dark band on the screen. Try moving any magnets or magnetic devices away from the TV to see if it improves the image.

If none of these solutions work, it may be best to contact a professional TV repair technician who can diagnose and fix the issue. They can ensure that the repair is done correctly and safely, and can help prevent further damage to the TV.

Change input device to some other like a DVD player.
Switch off TV, switch off power, remove plug and wait for 48 hours and retry. If problem persists, call in a qualified service technician.

Tell me if this is what you see: set comes on and after a few minutes (it has sound) you see a odd colored band of noise very dark and top to bottom to the right of center on the screen?

This is either 1 of 2 things, first it could be faulty panel tabs , in this case, there is nothing you can do and is unrepairable....2) you could take the back off the tv and you will see 2 ribbons going from your t-con board to the panel tabs (top center of tv) remove them carefully and reseat them. This is a common problem. Tv repair tech 15 years! Best of luck.

Is there a Tuner, or Cable Box Involved? If not i'd say your TV is dead

You would better served replacing monitor you can buy one for about $100-$120 dell if you lie has one for $99

Pop sound is probably the Lamp or maybe the color wheel. When you unplug and try it on do you hear a whirling or winning sound ? Is it followed by a slight ticking sound ? If you get the whirling and a ticking sound it's probably a bad lamp. If you don't hear the whirling sound you may have a bad color wheel. The parts are both made of glass. The pop you heard was one of them breaking. If you can't tell, order a lamp you will need to change it eventually anyway.

YOU MAY HAVE A DEFECTIVE Y DRIVER BOARD OR A RIBBON CABLE THAT HAS COME DISCONNECTED. THIS NOT USUALLY THE PANEL SINCE THE PANEL DOES TURN ON. TAKE IT TO AN AUTHORIZED SERVICER.

the reflecting mirror is likely loose and falling down inside the light reflecting tube. you should have seen the band getting darker and larger,
the small mirror is in front of the lamp and bends the light,
remove the lamp and look down the tube (light path)
