Samsung DLP 50-Inch TV Problems [Complete Troubleshooting Guide]

A Digital Light Processing (DLP) TV uses tiny mirrors to project images onto a screen. New models of DLP TVs, like the 50-inch Samsung DLP, have long-lasting DLP lamps that give users around 7,000 hours of screen time. That said, some watchers run into Samsung DLP 50-Inch TV problems that require troubleshooting. 

Stop guessing how to solve Samsung DLP 50-inch TV problems because this guide has all the tips you need to get back to enjoying your favorite shows. 

DLP TV Troubleshooting Audio With No Picture

There are six things to try if your Samsung DLP TV needs troubleshooting because of no picture. First, we’ll discuss all six ways to alleviate your Samsung DLP 50-Inch TV problems below. 

Tighten The DLP Lamp

Sometimes you’ll get audio with no picture with a Samsung 50-inch DLP TV because the DLP lamp isn’t correctly inserted. Tighten the DLP lamp to fix the picture. Remember, you’ll have to unplug your TV and pull it from the wall because access to the DLP lamp is at the back of the TV.

Avoid Overheating Your TV

Store your TV in a place where it’ll get proper ventilation to reduce the chance of overheating. Another good practice is to let your TV cool between viewing sprees and lower your brightness, color, and contrast settings to use less power. 

Watch For Warning Signs

Keep an eye open for warning signs with your Samsung DLP TV. Common warning signs are the Samsung DLP TV lamp light flashing, faded colors, and a popping sound if the DLP lamp burns out. 

Reboot Your Receiver

If you’re not getting a picture with your Samsung TV, reboot the receiver. 

You can reboot your receiver by unplugging your Samsung TV for around 30 seconds before plugging it into a working outlet. 

Investigate Your Picture Failure

You’ll need to investigate why images aren’t appearing on your DLP TV to properly troubleshoot Samsung projection TV problems. Check for lamp failure or problems with the TV ballast that powers the lamp. 

Replace LCD Inverter

If you have an LCD TV, you might have no picture because of a damaged LCD inverter. Similar to a lamp light in a DLP TV, the inverter in an LCD TV helps produce the picture. You’ll need to replace or repair your TV if this gets damaged.

Samsung DLP Shutting Off Without Warning

Few things are as annoying as your TV shutting off mid-show. If you’re experiencing this type of problem, follow these Samsung DLP television troubleshooting tips below. 

Power Outage

One of the easiest ways to solve Samsung DLP 50-Inch TV problems is to ensure it’s getting enough power. Plug another device into your TV outlet to check if it’s a working outlet. If not, contact an electrician or check if your neighborhood is experiencing a power outage. 

Mainboard Problems

One of the reasons your 50-inch Samsung DLP TV might be shutting off without warning is because of problems with the mainboard. The mainboard is like the brain of a high-tech gadget like a Samsung DLP TV.

Dust, water damage, heat damage, or defective wiring could be the culprit for your TV shutting off without warning. If that’s the case, clean your mainboard of dust, then consider Samsung DLP TV repairs or replacing your mainboard.

Power Supply Problem

If you’re not experiencing a power outage, you could have a power supply issue resulting in your TV shutting off without warning. Inspect your power cable for damages, and ensure that your outlet works with other devices. 

Samsung TV Lamp Burns Out

DLP TVs use lamps to project light onto mirrors to produce crisp, clear images on your screen. However, like all light bulbs, your DLP lamp can burn out and dim over time.

Lifespan of Lamp

If your Samsung DLP TV lamp light is flashing, it’s approaching time to replace the lamp light before it burns out. 

The lifespan of a DLP lamp is around 7,000 hours of screen time, though this can change depending on your brightness settings and heat damage from overuse. 

Lamp Replacement

When your Samsung DLP TV lamp light is flashing, you’ll need to replace the bulb to continue enjoying high-image quality. 

Luckily, replacing a burnt-out DLP TV lamp is easy. All you need to do is remove the lamp door, release the clip holding it in place, and pull out the old bulb. Simply insert a replacement, ensuring you’ve tightened it well, put the clip back into place, close the lamp door, and enjoy. 

Flickering of TV

If your TV is flickering, it’s likely due to an improperly connected cable. Check that all HDMI cords, your power cable, and other devices are well connected, and no cords show signs of damage.

Disposal of Lamp

Properly recycle your burnt-out DLP lamp light by bringing it to a nearby recycling facility, arranging pick-up with an online recycling service, or returning it to the place you purchase new lamp lights from. 

Poor Picture Quality of Samsung TV

You can’t go on watching TV with poor picture quality when a DLP TV is all about getting cinema-quality images. If poor picture quality is one of your Samsung DLP 50-Inch TV problems, follow the steps below to troubleshoot the issue. 

Perform a Soft Reset

A soft reset consists of unplugging your TV for 30 seconds to one minute and replugging it in. Perform a soft reset first to help improve the picture quality in your DLP TV.

Replace HDMI Cables

If you’re getting a poor picture, it may be because your HDMI cables are damaged. Try replacing old HDMI cords with new ones to see how it improves your image quality.

Update Firmware

Your image quality could be suffering because you need to update your TV’s firmware.

To update your firmware, press Menu on your remote and enter Settings. From Settings, find the Support tab and press Software Update. You should be able to select Update Now. However, if not, use your remote to change the source to Live TV, then try again.

Check The TV Settings

Improve your picture quality by adjusting the brightness, contrast, image sharpness, and color. 

Adjust your settings back to 100% for the best picture quality possible but remember to keep your device well-ventilated since full settings can cause overheating. 

DLP TV White Spots

Samsung DLP white dots usually means it’s time to replace the DLP chip. However, your best bet is to try using a can of compressed air around the lamp light and check if that helps.

Replace DLP Chip

DLP or digital micro-mirror device (DMD) chips are the millions of mirrors that produce impeccable images. 

Over time, DLP chips wear down from heat damage, dust, and humidity, causing mirrors to get stuck and leave white dots on your screen. Once the first dot appears, more are likely to follow, so it’s a warning sign you’ll need to replace the DLP chip soon.

Buzzing Sounds

Buzzing sounds are one of the common Samsung DLP 50-Inch TV problems, usually caused by overheating. Improve the ventilation where your TV is, or you may need to replace your color wheel. 

Proper Ventilation of the TV Area

Place your TV in an area with good ventilation to reduce overheating your Samsung 50-inch DLP TV. If you don’t want to reduce your brightness, color, or contrast settings, consider purchasing a TV fan to help cool down your device and lengthen its lifespan. 

Replace Color Wheel

DLP TVs use light, mirrors, and a color wheel to produce cinema-quality images in your home TV. However, if you start hearing buzzing sounds, it may be time to replace the color wheel. 


Now you know how to solve Samsung DLP TV problems if they come your way. Whether you lose audio or power, hear buzzing sounds, or see white spots, this Samsung 50-inch DLP TV troubleshooting guide has all the answers to common problems and questions.
