TCL Installation Method

A stuck logo problem in an LED/LCD TV means the TV powers on, displays the brand logo, but doesn’t proceed to the menu or channel display.
This is very common in LCD/LED TVs, and it usually points to firmware/software corruption or sometimes a hardware issue on the mainboard.

Here’s a step-by-step method to solve it, starting from the easiest fixes to advanced repair:

1️⃣ Check the Remote & Buttons First

Make sure the TV isn’t in demo mode or hotel mode (sometimes these cause logo freezes).
Disconnect remote and try powering on via TV buttons.
Perform a hard reset:
- Unplug TV from power.
- Press and hold Power button on TV for 15–20 seconds.
- Plug back in and turn on.

2️⃣ Try a USB Software Update (Firmware Flash)

Most stuck logo issues are fixed by reinstalling the correct firmware.

What you’ll need:

A USB flash drive (preferably 4GB–8GB, formatted to FAT32).
Correct firmware file for your TV’s model and mainboard version.
- Example: For a TCL V8-M901K01-LF1V076 board, you need the exact .bin or .pkg file from the manufacturer’s website or service resources.
A working PC to load the firmware.

Steps:

Download the correct firmware for your TV’s exact mainboard model (you can find it on the board label inside the TV).
Format USB to FAT32.
Copy firmware file to root of USB (do not rename unless instructed).
Turn off TV and unplug power.
Insert USB into TV’s USB port.
Press and hold the correct boot/update key combination while plugging in power:
- Common: Power + OK or Vol+ + Power (check service manual).
Keep holding until the TV’s LED blinks and update starts.
Wait until the process finishes — TV will reboot.

3️⃣ If USB Update Fails → Use ISP/Programmer Method

If firmware is badly corrupted, USB update might not start.
In that case:

You’ll need to read/write the eMMC or SPI flash directly.
Tools like RT809H, CH341A, or SkyPro can write the correct dump file.
Steps:
1. Identify storage chip (eMMC or SPI Flash).
2. Connect programmer (via clip or soldering).
3. Write correct firmware dump.
4. Test TV.

4️⃣ Check Power Supply & Mainboard

Sometimes stuck logo is due to unstable voltages on the mainboard:

Measure standby voltage (usually 3.3V / 5V).
Check main processor core voltages (1.2V, 1.5V, 1.8V, etc.).
If any are missing or unstable → check the DC-DC converters or replace faulty ICs.

5️⃣ If All Else Fails → Replace Mainboard

If both USB update and chip programming fail, and voltages are fine, the main SoC may be damaged.
Replacing the mainboard is the fastest option.

💡 Pro Tips for Technicians

Always match firmware with mainboard model, not just TV model.
Use service remote codes to enter recovery if available.
Keep backup firmware dumps of working boards for future repairs.
If TV has Android OS, use its recovery mode to wipe data/cache before flashing.

Here’s how to install or update TCL TV software from a USB drive depending on your TCL model—whether it’s Android TV, Google TV, Roku TV, or others.

Method 1: TCL Android TV (Including Google TV models)

Follow these steps to manually install firmware from USB:

Download the correct firmware file matching your TV model and chassis from TCL support or trusted sources.
Prepare a USB drive:
- Format it to FAT32.
- Copy the firmware file to the root directory of the drive.
  - For .img updates: extract the ZIP and place Update.img directly on the drive.
  - For OTA .zip updates: place the .zip file as-is on the drive. (Medium, TCL, TCL Support)
Perform the update:
- Power off the TV.
- Insert the USB drive.
- Press and hold the physical power button on the TV (typically on the back or side) while powering it back on.
- Release when you see a blinking light or update prompt.
- The process will begin—don’t remove the USB. After completion, the TV will restart automatically. (TCL, TCL Support)

Method 2: TCL Roku TV

If your Roku TV isn’t online, you can still update software manually:

Download the .rokutv update file from the Roku update portal by entering your TV’s brand and model. (TCL Support)
USB preparation:
- Use a USB 2.0 flash drive that's 256 MB or larger, formatted to FAT32. (TCL Support, Roku Community)
- Copy the update.roku file to the root of the drive.
Install the update:
- Insert the USB into the TV.
- Navigate on the TV to Settings → System → System update → I can’t connect.
- The TV will display a 12-digit validation code.
- Enter that code on the Roku update website for confirmation.
- A 6-digit code will then appear—enter that on the TV to initiate the update. (TCL Support)

Tips from Other Users & Community Advice

Use an MBR-partitioned, FAT32 USB, and plug into a USB 2.0 port, not 3.0, for better compatibility. (Reddit)
For ZIP vs IMG updates:

"It must be zipped … TV will unzip itself when you choose update from USB option"
"Depends, if you download OTA image then it must be zip, if you download img file it need to be .img file directly on root of usb!" (Reddit)

Quick Comparison Table

TV Type	File Type Needed	USB Format	Update Procedure
Android / Google TV	`.img` or `.zip`	FAT32 (root only)	Power off → Insert USB → Hold power button while turning on → Update starts and auto restarts
Roku TV	`.rokutv` file	FAT32, USB ≥256 MB	Insert USB → TV shows circle code → Enter on Roku site → Get rollback code → Enter on TV → Update begins

Final Thoughts

Always confirm the correct firmware for your model before proceeding.
Keep the TV powered during update to avoid bricking.
Let me know your specific TCL model if you’d like help finding the right firmware or need model-based instructions!
