About Board Level
Board Level publishes practical, board-level guides to diagnosing and repairing flat-panel televisions: LCD and LED-backlit sets, and the plasma TVs that are still in use years after production ended.
Who it is for
People who are comfortable with a screwdriver and a multimeter and want to understand what is wrong before spending money: owners of a TV that has stopped working, hobbyists, and anyone deciding whether a set is worth repairing at all. The guides assume no formal electronics training, but they do assume care.
How the guides are checked
- Facts that come from a law, a standard or a manufacturer are linked to that source, such as the EU directive on electrical waste or a manufacturer's own support pages.
- Much of TV repair knowledge is convention: the way a brand tends to number its boards, or the fault a given board type tends to develop. Those points are written as tendencies, never as rules, and the guides always come back to the number printed on the board and the model and version label on the TV.
- No figure is given without a basis. Where a value depends on the set (a supply voltage, a panel's sustain voltage), the guides point you to where it is printed rather than quoting a number that may not apply.
- Guides are dated, and updated when something is found to be wrong or out of date.
What Board Level does not do
- It does not sell parts, boards or repair services, and it does not recommend or rank sellers.
- It does not provide component-level schematics or copy service manuals, which belong to their manufacturers.
- It does not encourage anyone to work on live mains circuits. Several checks described here are done with the set unplugged; those that need power say so and explain the risk.
Brand names and part numbers are used only to identify products. They belong to their owners, and Board Level has no connection with any manufacturer. Photographs are free-licensed; see photo credits.
About this domain
From roughly 2010 to 2019 this domain was the address of an online shop called Discount TV Parts, which sold replacement circuit boards for flat-panel televisions. Board Level has no connection with that business or its owners, does not sell parts, and reuses none of its text, images or branding. Old product links on this domain now lead to the guide closest to the board they described, usually the guide to reading part numbers or the guide to that type of board.
