I’m having a problem where my television powers on, shows the startup logo, and then shuts off. It continuously does this until I unplug it. How do i figure out what needs replaced?
TV MODEL: P502ui-b1
edit:
i don’t see anything that looks wrong besides part of the speaker that looks a little crumpled

blt54321 you will have to remove the back of your Tv and see if there are any components on the power board that look damged (domed, leaking caps etc.) Post some good pictures with your question so we can see what you see. This could be a power noard, main board error but also a firmware issue. Checking on firmware upgrades for you right now. The turning off is usually casued by the power board since it cannot “communicate” with the main boad etc. We would need to see your board and the connectors closely. Vizio is not DIY friendly and schematics etc. are very difficult (if at all) to come by. We’ll realy on you for more information etc., to assist you with this

alright i added some photos.
i added another photo that looks strange. Maybe its just thermal paste but it looks wrong.
Is that substance soft and gooey or hard? If it is hard it is just some adhesive to keep the caps in place. No firmware update available. so the issue must be on one of the boards
yea its hardened. This might actually be a lost cause though, i searched for replacement parts for the P502ui-b1 but could only find boards for the P502ui-b1E.
