If you are preparing to repair your Westinghouse television, the most important step happens before you ever open the back panel. Identifying the correct part number is the foundation of a successful repair. At TVpartsToday, known as The World's #1 Hub for DIY TV Repair, we have helped thousands of customers avoid costly mistakes by focusing on this exact step. Westinghouse TVs often display multiple numbers on each board, and knowing which one actually matters can save you time, money, and frustration.
The key rule is simple and applies to every repair. Always use the manufacturer’s part number, not the board number. Board numbers are used during production and may appear on multiple boards that are not interchangeable. Relying on them can easily lead to ordering the wrong component and delaying your repair.

Identifying Westinghouse Power Supply Boards
The power supply board is responsible for delivering consistent voltage to every component inside your television. When this board begins to fail, common symptoms include no power, random shutdowns, or a TV that attempts to start but does not stay on.
Westinghouse power supply boards typically include a white barcode sticker that contains several numbers. Among these, only one is the correct part number. The most common formats include a combination of letters and numbers arranged in a structured pattern, often separated by dashes.
Below are example of the two most common part number formats for Westinghouse power supply boards:
Because multiple identifiers are printed on the same label, it is easy to confuse the correct number with serial codes or manufacturing references. Taking the time to carefully review the sticker and isolate the proper format is essential before placing an order.
Understanding Westinghouse Main Board Numbers
The main board acts as the central control system for your TV, managing inputs, audio processing, video output, and smart features. When this component fails, the TV may still power on but display no signal, produce no sound, or freeze during operation.
Westinghouse main board part numbers are usually found on a white label attached to the board. These numbers often follow a straightforward format, commonly appearing as an eight digit sequence or a shorter combination that includes letters and numbers.

It is important to ignore any large numbers printed directly onto the circuit board itself. These are board numbers and do not guarantee compatibility. The barcode sticker remains the most reliable source for identifying the correct replacement.
Locating Westinghouse T-Con Board Part Numbers
The T-Con board plays a critical role in delivering image data from the main board to the display panel. When it begins to fail, you may notice issues such as vertical lines, distorted colors, flickering images, or partial screen loss.
T-Con boards are often the most difficult to identify because their part numbers are not always presented clearly. In many cases, the number is printed in small text, etched directly onto the board, or located on the reverse side. The format may include a segmented combination of numbers and letters that differs from other components in the TV.
Below are example of the two most common part number formats for Westinghouse T-con boards:
Because these identifiers can be subtle and easy to overlook, careful inspection is necessary. Using proper lighting and examining both sides of the board can help reveal the correct number.
Why Part Number Accuracy Is Critical
Westinghouse televisions, like many modern TVs, can include multiple internal variations within the same model line. This means that two TVs with the same model number may use different boards depending on production batch or component sourcing.
Ordering the wrong part can result in compatibility issues such as improper voltage delivery, missing inputs, display errors, or a complete failure to power on. In some cases, installing an incorrect board can create additional problems rather than solving the original issue. Matching the exact part number ensures that the replacement is designed specifically for your TV.
Final Thoughts on Westinghouse TV Repairs
A successful DIY repair starts with accurate identification. By focusing on the barcode label, avoiding board numbers, and verifying the correct part number before ordering, you greatly increase your chances of completing the repair quickly and correctly.
