Echosonic ESTV 29D1 TNT 8MB Dump for TP.SIS231.P83 Boot Loop

User question

dump led echosonic estv 29d1

Artificial Intelligence Response

Direct answer to the question

For Echosonic ESTV 29D1 / ESTV 29D1 TNT, the matching firmware dump appears to be the package named:

• ECHOSONIC 29LED ESTV29D1 TNT.rar
• Compressed size shown online: 5.35 MB
• Intended flash size: 8 MB
• Typical SPI flash: 25Q64 / GD25Q64, 64 Mbit, 3.3 V

A MediaFire page currently lists this exact file name for download. (mediafire.com)

Before writing it, confirm these hardware details on your TV:

Item	Expected / reported value
TV model	Echosonic ESTV 29D1 / ESTV 29D1 TNT
Mainboard	usually reported as TP.SIS231.P83 C13116; one Arabic repair listing writes tp.sis213.p83 c13116, likely a typo, so verify the PCB silkscreen
SPI flash	25Q64 / GD25Q64, 8 MB
Panel	online listing reports HV320WX2, but some similar dumps may be for different panels; check the panel sticker before flashing

The Softaawy repair listing specifically references “echosonic estv 29d1 tnt”, board code C13116, panel HV320WX2, and 8 MB flash size. (softaawy.com)

Detailed problem analysis

The term “dump” in TV repair usually means a full binary image read from the SPI flash memory. In this chassis family, the firmware is usually stored in an SOIC-8 SPI NOR flash such as:

• 25Q64
• GD25Q64
• W25Q64
• MX25L6406

A 25Q64 is a 64 Mbit device, which equals:

\[ 64 \text{ Mbit} \div 8 = 8 \text{ MB} \]

So for direct programmer flashing, the correct full dump should normally be 8 MB / 8,388,608 bytes after extraction.

For TP.SIS231-family boards, repair references also mention a USB recovery file commonly named:

SISEU23X8M.bin

This file name is used by many SIS231 bootloaders, but the content must match the exact mainboard + panel + tuner/region + remote-control configuration. Elektroda repair references note that TP.SIS231.P83 boards commonly use an 8 MB GD25Q64 SPI flash and that USB recovery often uses SISEU23X8M.bin. (elektroda.com)

The important point: do not flash a random TP.SIS231.P83 dump only because the board number looks similar. A wrong dump may boot but cause:

• inverted image;
• solarized/negative colors;
• no backlight control;
• wrong LVDS mapping;
• remote control not working;
• tuner region mismatch;
• boot loop or standby-only fault.

Practical flashing procedure

Option 1: Direct SPI programmer method — recommended

Use this if the TV is dead, stuck on logo, restarts continuously, or does not read USB.

1. Open the TV and identify the SPI flash

   • Look for an SOIC-8 chip marked 25Q64, GD25Q64, W25Q64, etc.
   • It may be marked as U5 on TP.SIS231 boards.

2. Read and save the original dump first

   • Even if corrupted, save it.
   • It may contain useful option data, panel settings, remote table, or region configuration.

3. Use a 3.3 V SPI programmer

   • Suitable programmers include:
     • CH341A, preferably with verified 3.3 V output;
     • RT809F / RT809H;
     • TL866 series;
     • TNM5000 or equivalent.

4. Erase, blank-check, write, verify

   • Do not skip verification.
   • If erase or verify fails, replace the SPI flash IC.

5. Program the extracted 8 MB .bin file

   • The .rar archive must be extracted first.
   • Do not write the compressed .rar file directly.

6. Reinstall the chip

   • Observe pin-1 orientation.
   • Clean flux residue.
   • Inspect for bridges with a magnifier.

Option 2: USB recovery method

Try this only if the bootloader is still functional.

1. Format a small USB stick as FAT32.
2. Copy the firmware file to the root directory.
3. If required by the chassis, rename it to:

SISEU23X8M.bin

4. Disconnect AC power.
5. Insert USB.
6. Reconnect AC power.
7. Wait several minutes.
8. If the standby LED blinks, do not interrupt power.
9. After completion, disconnect AC, remove USB, then power on normally.

Repair references for TP.SIS231 platforms describe USB recovery using SISEU23X8M.bin on a FAT32 USB drive, and warn that the file must match the exact hardware configuration. (elektroda.com)

Post-flash checks

After flashing, check:

• TV boots past logo;
• image is not upside down;
• colors are correct;
• backlight dimming works;
• sound works;
• remote control works;
• tuner finds channels;
• HDMI/USB inputs work.

If the picture is inverted or colors are wrong, enter the service menu and adjust panel options such as:

• LVDS Map
• JEIDA / VESA
• Mirror
• Flip
• Panel Type
• Bit depth: 6-bit / 8-bit

Common SIS-platform service-menu sequences include:

MENU 1147

or similar variants, depending on the remote and firmware. TP.SIS231 references specifically mention changing LVDS and mirror settings after flashing if video is inverted or colors are wrong. (elektroda.com)

Important caution

There is a small inconsistency in online listings: one repair listing writes the mainboard as tp.sis213.p83 c13116, while this chassis family is commonly known as TP.SIS231.P83. Treat that as a possible typing error, not proof of compatibility. Confirm the real marking printed on your PCB before programming. (softaawy.com)

Also, firmware dumps are usually proprietary. Use them only for legitimate repair or restoration of the same device you own or are authorized to service.

Brief summary

Use the Echosonic ESTV 29D1 TNT 8 MB dump only if your TV matches the hardware: C13116 board, 25Q64/GD25Q64 SPI flash, and matching panel. Back up the old SPI content first, program the extracted 8 MB .bin with a 3.3 V programmer, verify the write, and then adjust panel settings in the service menu if the image is inverted or colors are wrong.
