This board serves as the central processing unit of your TV, handling video processing, smart TV functions, HDMI input management, and Wi-Fi connectivity. Replacing a failed main board typically resolves issues such as a TV that won't power on, no picture with backlight present, no sound, unresponsive HDMI ports, and lost smart TV or Wi-Fi functionality. Note: a software\/firmware update may be required after installation to pair the board with your specific LCD panel.\u003c\/p\u003e\n\u003ch5\u003eContact Me\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"mailto:info@tvpartsforsale.com?Subject=TVPartQuestion\"\u003eASK A QUESTION\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eKey Features\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eOEM Sony replacement main board — guaranteed fit for compatible models\u003c\/li\u003e\n\u003cli\u003eRestores full smart TV, HDMI, Wi-Fi, and video\/audio functionality\u003c\/li\u003e\n\u003cli\u003eResolves Sony \u003cspan style=\"color: rgb(255, 42, 0);\"\u003e3 red\u003c\/span\u003e blinks error and no-power conditions\u003c\/li\u003e\n\u003cli\u003eTested and pulled from working units or new old stock\u003c\/li\u003e\n\u003cli\u003eFast shipping from our US warehouse\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eImportant Notes\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eVerify your board number matches A5056853A before ordering\u003c\/li\u003e\n\u003cli\u003eA firmware update is typically required after installation — download from \u003ca href=\"https:\/\/esupport.sony.com\/\"\u003eesupport.sony.com\u003c\/a\u003e using your model number\u003c\/li\u003e\n\u003cli\u003eInstallation requires basic electronics knowledge; professional installation recommended if unsure\u003c\/li\u003e\n\u003cli\u003eThis is a replacement part only — no tools or installation service included\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SONY","offers":[{"title":"Default Title","offer_id":48621904986336,"sku":"A-5056-903-A","price":74.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0668\/4793\/2640\/files\/A-5056-903-A.jpg?v=1778619306"}],"url":"https:\/\/tvpartsoutlet.com\/collections\/sony-parts.oembed","provider":"TV Parts Outlet","version":"1.0","type":"link"}
