Philips 40PFL9704H/12 Firmware Upgrade and Driver Availability

User question

40Pfl9704h/12 software upgrade and drivers available

Artificial Intelligence Response

Direct answer to the question

For the Philips 40PFL9704H/12 LCD TV, software/firmware support is still referenced on Philips’ official support pages, but the TV is discontinued. Philips lists a Software & drivers section for this model, and the latest firmware history shown for this chassis is Q5492_0.26.78.0, also commonly represented as 000.026.078.000. (philips.co.uk)

There are no PC-style “drivers” for this TV. For a television, Philips “Software & drivers” mainly means:

• TV firmware update files.
• Firmware readme/history documents.
• End-user licence files.
• Open-source software packages where applicable.

Use the official Philips 40PFL9704H/12 support page and select Software & drivers. Philips’ own update guidance says that if software is available, it appears in the model’s Software and Drivers area; the firmware readme explains the update procedure and the actual update file is downloaded from there.

Detailed problem analysis

The firmware history document for this Philips TV platform lists the most recent entry as:

2. How to check the current software version on the TV

On most Philips sets of this generation, use the remote control:

1. Press Home.
2. Go to Setup / Configuration.
3. Open Software settings.
4. Select Current software info.

3. How to obtain the firmware

Use Philips’ official support route:

1. Go to the Philips support site.
2. Search for 40PFL9704H/12.
3. Open the product support page.
4. Select Software & drivers.
5. Download the firmware/update file if it is still offered in your region.
6. Also download/read the Firmware upgrade readme or Firmware history document.

Philips’ general update instructions state that the Software and Drivers section appears when an update is available, and that the readme file contains model-specific directions. (usa.philips.com)

Important note: because this is a discontinued 2009/2010-era TV, Philips pages in different countries may not show exactly the same downloadable items. Some regional pages may show only the firmware history, EULA, or open-source package rather than the actual installable firmware ZIP. If the actual firmware ZIP is not visible, use another Philips regional support page for the same exact model or contact Philips support.

Practical firmware update procedure

USB preparation

Use a simple USB flash drive:

• Preferably USB 2.0.
• Preferably 2 GB to 8 GB.
• Format as FAT32.
• Avoid NTFS or exFAT.
• Avoid USB hard drives.

After downloading the Philips firmware ZIP:

1. Extract the ZIP file on your computer.
2. Look for the update file, usually named something like:

autorun.upg

3. Copy the extracted firmware file to the USB stick as instructed by the Philips readme.
   Depending on the exact Philips instruction file, it may need to be:
   • in the root of the USB drive, or
   • inside an upgrades folder.

For this older generation of Philips TV, the most common method is to place the extracted autorun.upg file on a FAT32 USB stick and let the TV detect it.

Updating the TV

1. Turn the TV on normally.
2. Insert the USB stick into the TV’s USB port.
3. Wait for the software update prompt.
4. Confirm the update.
5. Do not remove the USB stick.
6. Do not switch off the TV.
7. Wait until the TV restarts by itself.

Philips’ update instructions warn that the update must be completed using the directions in the firmware readme for the specific model. (usa.philips.com)

Drivers: what is and is not available

Not available

There are no normal Windows, macOS, or Linux “drivers” for the 40PFL9704H/12. A TV connected by HDMI behaves like a display device; your computer uses the graphics-card driver, not a Philips TV driver.

What you may need instead

Use case	What you need
Use TV as PC monitor	HDMI cable; set PC resolution to 1920 × 1080
Play media from USB	USB storage formatted in a supported format
Stream media over network	DLNA/UPnP media server software on the PC
Remote/control integration	Philips Joint Space support, if enabled by firmware
Modern smart TV apps	External HDMI streaming device recommended

The old Net TV functionality on these Philips models is generally obsolete because many original services and security protocols are no longer compatible with current online services. In practice, for Netflix, YouTube, Prime Video, Disney+, etc., use an external HDMI device such as a Chromecast, Fire TV Stick, Apple TV, Roku, Blu-ray player, or game console.

Practical guidelines

Recommended update checklist

Before updating:

• Confirm the exact model: 40PFL9704H/12.
• Check current TV software version.
• Use only firmware intended for 40PFL9704H/12 or its exact Philips-supported chassis/software family.
• Use official Philips sources where possible.
• Do not downgrade unless Philips specifically instructs you to.
• Do not interrupt power during flashing.

After updating:

1. Remove the USB stick.
2. Power the TV off.
3. Disconnect AC mains for 1–2 minutes.
4. Reconnect and verify the software version.

If the TV does not detect the USB stick

Try:

• Smaller USB stick.
• FAT32 format.
• MBR partition table rather than GPT.
• Place only the firmware file on the stick.
• Try both root directory and an upgrades folder if the readme is unclear.
• Re-download and re-extract the ZIP file.

Possible disclaimers or additional notes

• The TV is discontinued, so Philips may no longer actively provide the full firmware package on every regional support page.
• The latest firmware history still points to Q5492_0.26.78.0 / 000.026.078.000, but actual download availability may depend on region or Philips’ current archive status.
• Do not use random firmware from forums unless you are prepared for a possible boot failure. Firmware for similar Philips models may appear compatible but can differ in panel configuration, tuner region, Ambilight configuration, or NVM data.
