TV Power Supply Boards for Sharp

Sharp TV power supply boards can be used to repair televisions that might not otherwise be salvageable. When looking for a replacement power supply board for your TV, the most important thing is to find the one that's needed for your particular Sharp television model. You can find the board you need and learn more about it here.

A power supply board is the component inside of a television that converts the AC voltage that the television receives from its power cord to the lower voltages used by electronics. Typical AC wall outlets provide a 110-volt current that is too high for sensitive electronics like the integrated circuits found in modern LCD TVs. The power supply board is responsible for stepping the AC current down to manageable levels like 12-, 18-, or 24-volt currents and also converting it to DC power.

Below is a list of some of the Sharp television models of power boards:

• LC-32LB370U
• LC-70LE650U
• LC-50LB370U
• LC-40LE550U
• LC-70LE733U
• LC-46D43U
• LC-60C52U
• LC-52D65

The most obvious symptom of a bad power supply board is that the TV won't turn on. However, more unpredictable or subtle problems can be created by a power supply board defect. Another common symptom of a problem with the power supply board is a television that will stay in standby mode, but won't turn on fully, or a television that turns on after several attempts and seems to work sporadically.

There are several issues that commonly cause a power supply board to malfunction. Below is a list of a few of them to consider:

• Blown fuse: This problem will cause a television to not respond at all when you attempt to turn it on. In this situation, the fuse may have failed because of age or because of a one-time event like a power surge.
• Failed capacitors: When capacitors fail, they need to be replaced in order to repair the power supply board, or the board will need replacement. Capacitors will sometimes explode, leak electrolyte fluids, or burn up.
• Failed IC chips: When IC chips fail, it can be difficult to diagnose since there's usually no visible sign of the problem, and in most cases, it is generally advised to replace the board.
