I’m currently trying to diagnose my TV not powering and I do not have a manual. Here are a few notes: -Screen is black (does not power on). Sound does not work as well. -Performed the “flashlight test” and did not see any “no signal” or anything dimly lit to indicate it is a backlighting issue. Opened up the back of the TV and: -Backlighting board seems fine. I havent taken it out and it is covered by metal but I can see the coils and they do not looked burned. -Initially heard a “popping” sound when TV broke. However, I can not find any swollen transformers on any of the boards. -Standby light in the front of the TV is On when plugged in, this light is red. -Power On/Off Switch works. Standby light turns blue when the power button is turned on and stays blue. I could use some help determining what the issue is and what replacement parts I need to buy. Thank you for your assistance.
@dmaisel commonly, if your standby light turns on then it is a main board issue. We would need to know the exact model number for your TV and if you can post pictures of the boards as well as the interconnect cables with your question. Adding images to an existing question
