TV powers on, but there no picture or menu.

I have a Blaupunkt 40/148z LED TV that was previously completely dead (no power light or signs of life). I replaced the AV board with one I bought online and, after reassembling, the TV now powers on. It starts on standby mode, then the red standby light turns blue as normal when you press the power button. The back light also comes on. However there is no picture, and the menu won't come up. What could be causing this issue?

@hungergeist some of those TV's require a software update whenever you replace the main board. It might help if you can tell us what the Chassis number for your TV is as well as post some good pictures of your boards and interconnect cables. Agregar imágenes a una pregunta existente

How's it going I want to ask you a couple questions have you tried to unplugging all the wires from your TV like the HDMI to plug in for the TV honest chords all that stuff try unplugging all that Indian plug and all that back in that doesn't work check your cords check out your cord to see if there's a breakage or a splice or cut or damaged cords anywhere remind me to replace a cord and if that's not working very well could be the power supply board has failed and that will have to be replaced if none of these are working please let me know I'll be happy to find more things to get your TV back up and running
