TP.HV352T.PB753 is a combo smart-TV mainboard used in many budget/OEM Android LED TVs, typically in the 32–43 inch range. It combines:
It is commonly associated with the Novatek V3520 / V3520N platform, Android-based firmware, 8 GB eMMC storage, and often 1 GB DDR RAM, but the exact configuration depends on the TV manufacturer and LCD panel used.
If you are looking for firmware, the most important rule is:
Do not flash firmware only by board number. You must also match the LCD panel model and memory configuration.
The board marking TP.HV352T.PB753 identifies a universal TV motherboard platform. These boards are used by many brands and OEM assemblers, so the same PCB can appear in TVs sold under different brand names.
Typical functions integrated on the board include:
| Section | Function |
|---|---|
| Main CPU / SoC | Android TV processing, video decoding, UI |
| eMMC flash | Stores Android OS, boot partitions, apps |
| DDR RAM | Runtime memory |
| PSU section | Generates standby and operating voltages |
| LED driver | Drives the LCD backlight LEDs |
| Tuner | RF TV input |
| HDMI / USB / AV | External input interfaces |
| LVDS output | Sends video data to the LCD panel |
Because it is a combo board, troubleshooting must consider both the logic and power sections.
Commonly reported specifications for this board family are:
Exact specifications can differ between production batches.
For this board, the firmware usually depends on at least four things:
Board number:
TP.HV352T.PB753
SoC/platform:
Example: V3520N, V3520N0E
Memory configuration:
Example: 8G_512X2MB, meaning 8 GB eMMC and 2 × 512 MB RAM
LCD panel model:
This is critical.
The LCD panel model is usually printed on a sticker on the back of the display panel, for example:
The firmware contains panel parameters such as:
So, two TVs can use the same TP.HV352T.PB753 board but require different firmware.
Firmware files for this type of board may have names similar to:
allupgrade_an12_V3520N0E_8G_512X2MB_sos.binMeaning approximately:

Recommended checks:
Possible causes:
If the picture is white, negative, solarized, or inverted, it is often a panel parameter mismatch, not necessarily a hardware failure.
Possible causes:
Check:
Use this only if you are confident the firmware matches your board and LCD panel.
.bin file to the root directory of the USB drive.Example:
/allupgrade_an12_V3520N0E_8G_512X2MB_sos.binIf the TV does not detect the USB drive, try:
If the firmware boots but the display is wrong, enter the factory/service menu.
Common service codes used on many Chinese/OEM TV boards include:
1147
2580
8896The exact method varies by firmware. Typical sequences are:
Inside the service menu, look for:
| Setting | Purpose |
|---|---|
| Mirror / Flip | Corrects upside-down image |
| LVDS Map | Switches JEIDA/VESA format |
| Panel Type | Selects LCD timing |
| Backlight | Adjusts brightness/current behavior |
| Logo | Changes boot logo |
| IR Type | Selects remote-control protocol |
Be careful: incorrect service-menu changes can make the display unusable.
Many Android TV boards fail because of degraded eMMC memory. Symptoms include:
If the eMMC is physically worn out, flashing by USB may only temporarily fix the problem. The correct repair is to:
Professional tools include:
Some versions may use an external SPI NOR flash for early boot code. If corrupted, USB flashing may not start.
Typical SPI flash chips:
25Q32
25Q64
GD25Q32
W25Q64
MX25L seriesRepair method:
A CH341A programmer can sometimes be used, but level shifting and correct voltage are important. Many SPI flash chips are 3.3 V, but always check the marking.
Because this is a combo board, check power rails before assuming firmware failure.
Important rails may include:
| Rail | Typical use |
|---|---|
| 5 V standby | Standby controller, USB, logic wake |
| 12 V / 24 V | Main board supply or backlight section |
| 3.3 V | Logic, SPI flash, tuner |
| 1.8 V | eMMC I/O, DDR interface |
| 1.2 V / 1.1 V | CPU core |
| Panel VCC | LCD panel supply |
If a rail is missing or pulsing, suspect:
This board contains hazardous voltages.
Even after unplugging the TV:
Recommended precautions:
Before requesting or flashing firmware, record these details:
Board number: TP.HV352T.PB753
Panel model:
TV brand:
Screen size:
Resolution:
RAM:
eMMC size:
Original fault:
Standby LED behavior:
Backlight behavior:
Remote model:
Photo of board sticker:
Photo of panel sticker:The panel model is especially important. Without it, firmware selection is guesswork.
If your problem is:
| Symptom | Most likely direction |
|---|---|
| Stuck on logo | Firmware/eMMC |
| Red standby only | Power rails, bootloader, eMMC |
| Backlight but no image | Panel firmware, LVDS, panel supply |
| Inverted picture | Mirror setting or wrong firmware |
| Negative/solarized colors | JEIDA/VESA LVDS mismatch |
| Remote not working | Wrong IR configuration |
| No standby light | PSU section fault |
| Clicking/pulsing PSU | Shorted secondary rail or PSU feedback fault |
TP.HV352T.PB753 is a universal Android smart-TV combo motherboard, commonly based on the Novatek V3520N platform. If you need firmware, match not only the board number but also the LCD panel model, RAM/eMMC configuration, screen resolution, and remote-control type. Wrong firmware can cause inverted image, wrong colors, no display, or remote-control failure.
For repair, first distinguish between:
If you want, send the panel sticker model, TV brand, screen size, and symptom, and I can help identify the correct firmware direction or diagnostic steps.
