🧩 So what’s in the Box? Everything You Need!
Our Sony XBR-75X900F Repair Kit includes six essential boards, quality control inspected and matched for compatibility:

-
1-474-711-11 Power Supply – Converts AC power to various DC voltages for your TV's components.
-
1-474-713-11 Sub Power Supply – Manages standby and power sequencing operations.
-

-
1-458-998-11 Wi-Fi Board – Enables network connectivity and streaming features.
💡 TVpartsToday Tip: If your TV was hit by lightning or is totally dead with no obvious culprit, you should avoid replacing one part at a time. Damage often extends to multiple components - and that's where repair kits shine!
⚠️ When to Buy a Full Repair Kit
Not every repair requires a full kit , but here’s when it absolutely does:
✔️ You're Not Sure Which Board Is Bad – If your TV powers on but has distorted video, sound issues, or erratic behavior, it's likely more than one board is involved.
⚡ Your TV Was Hit by a Power Surge or Lightning Strike – These electrical events often damage multiple internal boards in one shot.
❌ You Already Replaced One Board But the Issue Persists – If you swapped out the power supply or main board and your problem still isn’t fixed, a second board may be the cause of the fault. Having all of the circuit boards on hand helps with troubleshooting!
🧩 Your TV Is Completely Dead – No power, no LED light, no response from the remote? One board likely failed and took others with it. A kit eliminates the guesswork.
💡 TVpartsToday Tip: Buying the full repair kit can actually save you money. Replacing one board at a time can add up - and if you accidentally fry a new board by pairing it with a defective one still in the TV, that’s a costly mistake.
🔍 Matching Part Numbers: Why It Matters
Each board in this repair kit is matched to your specific Sony model (XBR-75X900F) and selected by part number - not just appearance or model guesswork.
✅ Use part numbers like A-2197-252-A or 1-474-711-11 found on the white sticker or barcode label on your old boards.
🚫 Avoid using board numbers printed directly on the PCB - these are manufacturing reference codes and can mislead you into ordering the wrong part.
💡 TVpartsToday Tip: Still not sure what you need? Just send us a photo of your current board’s sticker - we’ll confirm compatibility for you!

🔧 DIY Installation Made Easier
Replacing multiple boards may sound intimidating, but with a little patience, it’s totally doable. Here’s how to make the job smoother:
-
Unplug your TV and place it face down on a soft surface.
-
Remove the back panel screws using a Phillips-head screwdriver.
-
Take photos of all ribbon cables and wire connections - future you will thank you!
-
Remove and replace each board, one at a time. Be gentle and thorough.
-
Reconnect everything, close the panel, and power it on.
💡 TVpartsToday Tip: Sometimes replacing the parts one-by-one is the answer! This helps with troubleshooting the issue and identifying which of your original parts failed. If the set was hit by lightning, however, it may be safer to replace ALL the boards at once!
🧠 Final Thoughts: Don’t Guess - Repair with Confidence
The XBR-75X900F Sony Repair Kit is the go-to solution when you're facing mysterious symptoms, surge damage, or multiple potential points of failure. It eliminates the stress of trial-and-error board swaps, ensures full compatibility, and brings your TV back to working condition the first time.
