It serves as the primary energy regulator, converting high-voltage alternating current (AC) from your wall outlet into the stable direct current (DC) required to power the TV&#8217;s motherboard and the backlight system.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Technical Specifications<\/h2>\n\n\n\n<p>While specific electrical tolerances can vary slightly based on the production batch, the BN44-01137A typically adheres to the following standards:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Input Voltage:\u00a0<\/strong>100V \u2013 240V ~ 50\/60Hz (Universal AC input).<\/li>\n\n\n\n<li><strong>Secondary Outputs:\u00a0<\/strong>Typically provides a 13V rail for the main logic board and varying high-voltage DC outputs for the LED backlight strings.<\/li>\n\n\n\n<li><strong>Connectors:<\/strong>\u00a0Includes a dedicated power input socket and specialized pin-out headers for the Main Board and the LED Panel connection.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Compatible TV Models<\/h2>\n\n\n\n<p>The&nbsp;<a href=\"https:\/\/www.all-battery.co.uk\/item\/20218633\/BN44-01137A\">BN44-01137A<\/a>&nbsp;is most commonly found in Samsung\u2019s TU7000 and TU8000 Crystal UHD series. It is specifically engineered for 55-inch displays. Compatible model numbers often include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>UN55TU7000FXZA<\/li>\n\n\n\n<li>UN55TU8000FXZA<\/li>\n\n\n\n<li>UN55TU8200FXZA<\/li>\n\n\n\n<li>UN55TU700DFXZA<\/li>\n\n\n\n<li>UE55TU7100 \/ UE55TU8000 (European variants)<\/li>\n<\/ul>\n\n\n\n<p>Note: Always verify the &#8220;BN44&#8221; part number on your original board before purchasing a replacement, as Samsung may use different power boards for the same TV model depending on the manufacturing region or panel type.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">When Should You Replace the Power Board?<\/h2>\n\n\n\n<p>The power supply is one of the most stressed components in a television. You should consider a&nbsp;<a href=\"https:\/\/www.all-battery.co.uk\/item\/20218633\/BN44-01137A\">replacement<\/a>&nbsp;if you encounter the following symptoms:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>No Power (Dead TV):\u00a0<\/strong>If the television fails to turn on and the standby light (usually red) is not illuminated, the power board has likely suffered a catastrophic failure, such as a blown fuse or a shorted capacitor.<\/li>\n\n\n\n<li><strong>The &#8220;Click of Death&#8221;:\u00a0<\/strong>If you hear a repetitive clicking sound when attempting to turn the TV on, it indicates that the PSU is stuck in a reboot loop, failing to stabilize the voltage required to boot the system.<\/li>\n\n\n\n<li><strong>Backlight Issues:\u00a0<\/strong>If the TV has sound and you can see a faint image when shining a flashlight on the screen, but the display remains dark, the LED driver section of the BN44-01137A may be faulty.<\/li>\n\n\n\n<li><strong>Intermittent Shut-offs:\u00a0<\/strong>If the TV works for a few minutes and then abruptly turns off, heat-sensitive components (like failing electrolytic capacitors) on the board are likely the culprit.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>The&nbsp;Samsung BN44-01137A&nbsp;is a vital internal component, specifically a Power Supply Unit (PSU), designed for modern Samsung LED televisions.
