Question 1

i’m getting no sound from my built-in tv speakers when i switch to an hdmi input like my playstation

Accepted Answer

DIAGNOSIS The TV is likely receiving an audio format from your external device that its internal speakers can’t decode, like Dolby Digital or DTS. It’s an HDMI handshake issue. FIX 1) On your TV, go to Settings > Sound > Expert Settings > HDMI Input Audio Format. Change it from ‘Auto’ to ‘PCM’. This tells the TV to request a simpler, universal audio signal. 2) If that doesn’t work, go into the sound settings on your external device (PlayStation, cable box, etc.) and manually set its audio output to ‘PCM’ or ‘Linear PCM’, not ‘Bitstream’. IF THAT DIDN'T WORK Check your TV’s sound output setting. Press the Home button, go to Settings > Sound > Sound Output. Make sure it’s set to ‘TV Speaker’ and not accidentally switched to an external audio system like ‘Receiver’ or ‘Bluetooth’. Cycle through the options. HEADS UP If you later add a soundbar via HDMI ARC, you’ll need to go back into the HDMI Input Audio Format setting and change it back to ‘Auto’ or ‘Bitstream’ for the soundbar to get the proper high-quality signal.

Question 2

the motion on my qled looks weird and jittery during sports or fast scenes, even with motion smoothing off

Accepted Answer

DIAGNOSIS This is often the ‘Judder Effect’ from the TV’s native 60Hz panel struggling with 24 or 30 frames-per-second content. The default Auto Motion Plus settings can also be a culprit. FIX Go to Settings > Picture > Expert Settings. Find ‘Auto Motion Plus’. Set it to ‘Custom’. You’ll see two sliders: Blur Reduction and Judder Reduction. 1) Set Judder Reduction to ‘0’. This is usually the main source of the unnatural, soap-opera-like smoothness. 2) You can leave Blur Reduction low (1 or 2) if you want, but start with both at 0 and see if the natural look fixes your issue. IF THAT DIDN'T WORK Make sure you’re in a proper picture mode. ‘Movie’ or ‘Filmmaker Mode’ will have motion processing disabled by default. Avoid ‘Dynamic’, ‘Standard’, or ‘Sports’ modes if you’re sensitive to this, as they often have aggressive smoothing turned on. HEADS UP No setting will make a 60Hz panel perfect for high-speed content. Some judder on panning shots is inherent. The goal is to minimize the artificial processing, not eliminate all motion blur.

Question 3

my tv remote (tm2340a) is super laggy or doesn’t respond unless i point it right at the tv

Accepted Answer

DIAGNOSIS The SolarCell remote uses both RF (radio frequency) and IR (infrared). The lag or need to point means it’s falling back to the slower IR mode because the RF connection is weak or interrupted. FIX 1) First, recharge the remote. Place it under a bright light (a lamp is better than room lighting) or in indirect sunlight for a few hours. A low battery can weaken the RF signal. 2) While it’s charging, restart your TV (unplug it from the wall for 60 seconds, then plug back in). This resets the RF receiver in the TV. IF THAT DIDN'T WORK There might be RF interference. Move other wireless devices (like routers, Bluetooth speakers, or even USB 3.0 cables near the TV) further away. Also, make sure nothing is physically blocking the TV’s bottom-center, where the receiver is. HEADS UP These remotes don’t use traditional batteries you replace. If it won’t hold a charge after proper light exposure, the internal battery might be defective and the remote itself needs replacing under warranty.

Question 4

how do i properly clean the screen on my qn43q60d without messing up the coating?

Accepted Answer

DIAGNOSIS You’re right to be cautious. Using the wrong cleaner or cloth can damage the anti-glare and anti-smudge coatings on QLED screens. FIX Use only a dry, soft, lint-free microfiber cloth first. Gently wipe in one direction. For smudges, slightly dampen part of the cloth with distilled water—never spray liquid directly on the screen. Wipe gently, then immediately dry-buff with the dry part of the cloth. That’s all you should need for 99% of cleaning. IF THAT DIDN'T WORK For stubborn spots, you can use a 50/50 mix of distilled white vinegar and distilled water, applied sparingly to the cloth, never the screen. Avoid the edges so liquid doesn’t seep in. Never use window cleaner, solvents, or any abrasive cloths. HEADS UP Pressure is your enemy. Don’t press hard, especially on a thin QLED panel. You’re wiping a coated surface, not scrubbing a countertop. Gentle is the way.

Question 5

there's a faint but annoying high pitched buzz coming from the back of my samsung qled, is this normal?

Accepted Answer

DIAGNOSIS That’s coil whine, a high-frequency noise from the power supply components. It’s not dangerous, but it can be irritating, especially in a quiet room. FIX First, check if it’s related to picture brightness. 1) Go to Settings > Picture > Expert Settings. 2) Turn off any auto-brightness features like ‘Eco Sensor’ or ‘Auto Brightness’. 3) Manually lower the ‘Backlight’ or ‘Brightness’ setting. Often, the whine changes pitch or stops when the power draw to the LED backlight changes. IF THAT DIDN'T WORK The issue might be specific to the internal power supply component. If the buzz is loud and constant, and you’re still within your return/exchange window, you might consider swapping the TV, as the level of coil whine can vary unit-to-unit. HEADS UP This sound is often more noticeable during bright, white scenes (like a hockey game or a spreadsheet). If lowering the backlight fixes it, you’ve found the workaround.

Question 6

my qn43q60d keeps saying network disconnected even though my wifi is fine, streaming apps won’t open

Accepted Answer

DIAGNOSIS The TV’s wireless connection is dropping or failing to authenticate. It’s a common handshake problem between the TV’s network hardware and some routers. FIX 1) Go to Settings > General > Network > Open Network Settings. 2) Forget your current Wi-Fi network. 3) Re-select it and enter your password fresh. This forces a clean reconnect. 4) If that doesn’t stick, restart your router, wait a minute, then restart the TV by holding the power button on the remote until the TV turns off and back on. IF THAT DIDN'T WORK The 2.4GHz band is more stable for these TVs. If your router broadcasts a combined 2.4/5GHz signal (SSID), try splitting them in your router settings and connect the TV to the 2.4GHz network only. Interference is less likely. HEADS UP If you’re using a mesh system, sometimes the TV gets stuck on a distant node. Try moving the node closer or, if your system allows it, temporarily disable the node hopping feature for the TV.

Question 7

my new samsung 60d tv won't power on, no lights, nothing at all, it's like it's dead

Accepted Answer

DIAGNOSIS This is almost always a power supply issue, either at the wall or the connection to the TV itself. The internal power board is rarely the first culprit. FIX Start simple. First, check your power strip or wall outlet is working. Then, trace the power cable from the TV to the wall. Make sure the plug is fully seated at both ends—the one going into the TV’s back can be stiff and might not be pushed in all the way. You’ll feel it click. Unplug it and plug it back in firmly. Then try the power button on the remote or the TV. IF THAT DIDN'T WORK Try a completely different power outlet on a different circuit. If it suddenly works, the original outlet or power strip is the problem. If it’s still dead with a known-good outlet, it's time to contact Samsung support, as the power supply unit might be faulty. HEADS UP Don’t immediately assume the TV is bricked. These new slim power cords can look plugged in but not be making full contact. Always test that first before going through a warranty claim.
