Whether you’re repairing a Sony TV with a blank screen, no signal, or power issues, getting the correct part number is the key to a successful DIY repair. At TVpartsToday, we’ve helped thousands of customers fix their own TVs — and when it comes to Sony, identifying the right part takes a little extra detective work. But don’t worry — we’ve got you covered with this no-nonsense breakdown of how to find and match Sony part numbers for T-Con boards, main boards, and power supplies.
💡 TVpartsToday Tip: Always match your part number, NOT the board number! Board numbers are used in manufacturing and often appear across incompatible models. Using them could lead you to the wrong replacement part — costing you time, money, and a lot of frustration.
PLEASE NOTE: In the following pictures, the manufacturer's part number is circled in GREEN and is the number you need to match to your part to ensure you get the correct part. The numbers marked with a RED "X" are board numbers used in the manufacturing process and matching these numbers will not guarantee a compatible part. We have not put a red "X" on all board numbers present on the parts pictured.
🔌 SONY POWER SUPPLY BOARDS: The Backbone of Your TV’s Power
The power supply board is usually the largest circuit board in your Sony TV — and it’s typically where the power cord plugs in. If your TV has no power, flickering lights, or shuts off unexpectedly, this board is your first suspect. 🔍
Two common Sony power supply part number formats:
-
Label Format: A solid 9-digit number beginning with "1"
-
Example: 147471312
-
Found printed on a barcode sticker or QR code sticker on the board.
-
Board Format with Dashes: A formatted number like 1-001-389-11
-
Found printed directly on the board or on a label.
-
If printed on a label, the dashes may be missing — so look carefully!
💡 TVpartsToday Tip: See multiple numbers on the board? Snap a photo and email it to info@tvpartstoday.com. We’ll identify the correct part number for you — quick and easy.
🧠 SONY MAIN BOARDS: The Control Center of Your TV
Sony main boards can be tricky — and here’s why: most of them don’t actually have the manufacturer’s part number printed on the board. 😱 Instead, you’ll find a reference number on a white sticker, and that’s where your journey begins.
Sony main board part number formats:
-
Example: A-1726-204-A
-
Or: A1726204A
⚠️ These numbers are not the final part number — but TVpartsToday.com has a massive cross-reference database. Just plug in the number from your sticker and we’ll do the rest!
💡 TVpartsToday Tip: If you’re unsure whether your board number is usable, just reach out. We’ll cross-check it for you and get you the right part the first time. 🛠️
🎨 SONY T-CON BOARDS: When the Picture Goes Haywire
Your Sony T-Con board (Timing Control Board) is responsible for transmitting data between the main board and the TV panel — basically telling the pixels when and how to light up. If you’re seeing vertical lines, flashing images, or just a black screen with sound, this could be the issue.
Common Sony T-Con part number formats:
-
LG-style format: 6871L-####X (e.g., 6871L-3930D)
-
Other format: ##.##X##.X## (e.g., 55.43T09.C01)
-
Sony-style reference: LJ94-39433C — often matches back to an internal Sony part number.
💡 TVpartsToday Tip: Sony T-Con boards are notorious for having no obvious part number. If you're stumped, email a photo of the board AND your TV model to info@tvpartstoday.com — we’ll match it for you!
