No video input to my 32 inch samsung smart tv. How do I fix it. Model number UA32EH4003

Unfortunately, most TVs only support closed captions on the RF (OTA or analog cable without a set-top box) input. For other sources, the captions are enabled at the source device or app.

The Samsung Series 8 UA65TU8000KXXS does support some subtitled files from the USB drive. However, the support is limited to select subtitle and video formats. What is the format for these videos? See page 134 of the E-manual for details; the menu section on the subtitles is shown starting on page 222.

The manual for this model is available on the product page: https://www.samsung.com/sg/tvs/uhd-4k-tv/tu8000-65-inch-crystal-uhd-smart-tv-ua65tu8000kxxs/ . The current link to the manual is https://downloadcenter.samsung.com/content/UM/202208/20220802172628638/NIKDVBADT-3.2.0_EM_NIKE_ASIA_ENG_220110.0.pdf .

I hope this helps.

(VLC can support a number of caption file types. See https://www.rev.com/blog/resources/how-to-add-captions-and-subtitles-to-vlc-media-player-videos-and-movies . There is also a plugin that lets the program find subtitle files automatically. One or both of these is probably why the video captions work on VLC for Android.)

The search query for this is

make model manual

size, in this case is irrelevant :>) Or of course you could read the manual that came with it.

Channels are set by whatever the input is from, cable, satellite box, IP PVR, Over-Air decoder, etc. Your television just relays what it sees from the Input/Source HDMI cable
..

Has the power button on the TV been used often or not? If so it could be worn out/stuck and the two button leads making unwanted contact.

Check and replace the CCFL lamp.

Fix your tv with black screen blinking light, popping sound noise. ... Watch QueueQueue ... TV Black Screen - Repair LCD LED PLASMA - Problems SONY LG .... I have a 60 inch samsung DPL tv how can I stop the humming or ... What do I do if my tvturns on but its just a black screen so sound no picture?.

Here is what to check when your TV is turned on, power light is ON, but no picture is seen or sound is heard:

1 - Be sure the component you are using (Xbox, Cable, SAT, ROKU) is turned ON.
2 - Check to be sure all cable and cords are securely connected to the TV inputs and component outputs.
3 - Make sure you are on the correct input as some TV's will show a black screen if there is nothing connected to that input.
4 - Unplug the input you are trying to use from the TV (such as an HDMI Cable) and plug it back in.
5 - Check for signs of damage on all cords and cables from the TV to all components.
6 - Make sure the TV is not in ENERGY SAVE MODE, press the button on the remote control to go back to normal mode.
7 - Unplug the TV for 10 minutes to see if there was a temporary one time issue with the TV.
8 - Disconnect the TV from power for 2 minutes, then when plugging it back in PRESS AND HOLD THE POWER BUTTON ON THE TV FOR 10 to 20 SECONDS to try and force the TV to reset.
9 - If after checking all these different issues, you may have a Faulty Power Supply Board, A Bad Capacitor on the Power Supply Board, Loose Wire Harness, or Loose Ribbon Connector in the TV itself.
10 - Most likely when a TV has the power light ON but NO PICTURE and NO SOUND, it is the Power Supply Board that has failed.

BTW, here are solutions for you to play iTunes movies on Samsung smart TV

you may need HDMI cable to see video.
