Ремонт саундбара Philips HTB5151K/51

Introduction

This tutorial provides a step-by-step guide to repairing the Philips HTB5151K/51 soundbar, specifically addressing issues when the device gets stuck on the starting screen. The repair involves updating the NAND firmware using a specific chip model, MICRON MT29F2G08ABAEAWP. Follow these steps to effectively resolve the problem.

Step 1: Gather Necessary Tools and Materials

Before starting the repair, ensure you have the following tools and materials ready:

• Philips HTB5151K/51 soundbar
• MICRON MT29F2G08ABAEAWP NAND chip
• Soldering iron and solder
• Screwdriver set (for disassembly)
• Multimeter (for testing)
• Computer with appropriate firmware update software
• USB programmer (if necessary for NAND programming)

Step 2: Disassemble the Soundbar

Carefully disassemble the soundbar to access the internal components:

1. Use the screwdriver set to remove screws from the back panel.
2. Gently pry open the casing to avoid damaging clips.
3. Take note of the placement of screws and components to ensure reassembly is easy.

Step 3: Locate the NAND Chip

Once the soundbar is open, locate the NAND chip on the motherboard:

• Identify the MICRON MT29F2G08ABAEAWP chip, which is typically rectangular and may have markings indicating its model.
• Use a multimeter to check for any visible damage or short circuits.

Step 4: Remove the Old NAND Chip

If the NAND chip is faulty, you will need to replace it:

1. Heat the soldering iron and carefully apply heat to the solder joints of the NAND chip.
2. Gently lift the chip using tweezers once the solder has melted.
3. Clean the area with solder wick to remove old solder.

Step 5: Install the New NAND Chip

Install the new MICRON MT29F2G08ABAEAWP chip:

1. Position the new chip in place, aligning it with the motherboard pads.
2. Apply solder to each joint while ensuring there are no bridges between pins.
3. Allow the solder to cool and solidify before proceeding.

Step 6: Program the NAND Chip (If Necessary)

If the new NAND chip requires programming, follow these steps:

1. Connect the chip to a USB programmer.
2. Use the appropriate software on your computer to upload the firmware.
3. Verify that the firmware upload is successful before disconnecting.

Step 7: Reassemble the Soundbar

Once the new NAND chip is installed and programmed, reassemble the soundbar:

1. Carefully place the back panel back on and secure it with screws.
2. Double-check that all components are properly connected and secured.

Step 8: Test the Soundbar

After reassembly, test the soundbar to ensure it functions correctly:

• Connect the soundbar to power and turn it on.
• Check if it boots beyond the starting screen.
• Test audio output to confirm that the repair was successful.

Conclusion

You have successfully repaired your Philips HTB5151K/51 soundbar by replacing and programming the NAND chip. This process can resolve issues related to the device freezing on startup. If problems persist, consider consulting a professional technician or exploring additional troubleshooting options.
